Product backgroundThe Baby Elephant Running Technology Co., Ltd. behind PaPa was established in November 2014 and was co-founded by two senior executives from Gumi and Huawei. In January 2015, PaPa Entertainment received an angel investment of 5 million yuan in the sea. The investors were former Alibaba and Tencent executives, as well as Northern Lights Venture Capital. In July 2015, PaPa Entertainment completed a Series A financing of 45 million yuan
Configuration brief
PaPa has 4 core processors of Rockchip RK3188 in terms of hardware configuration, and is equipped with the DLP digital optical processing chip of Texas Instruments as recently as domestic intelligent micro-projection. The 1G ram+8G rom has a resolution of 854×480 (FVGA). The brightness is 100 ANSI lumens, which is approximately equivalent to 450 lumens in the domestic light bulb machine. The contrast ratio is 1000:1. The light source is LED and the lifespan is 20,000 hours. The official stated that it can project a hundred-inch screen. v
The box is a modern, minimalist white style with a very young Q-color red logo in the middle, and the early crowdfunding version has slightly changed dimensions. It is thought that it is a square without careful look.
The size of the packaging box and the ordinary mobile phone packaging. If you don't say it, it's hard to believe that a projector is installed inside.
The back of the box is the conventional hardware parameters/character selling points/manufacturer information.
Open the lid of the box upwards. The inside of the box is black, highlighting the center white protagonist. The accessories are also packed in different size black cartons on the side.
Family portrait, accessories mainstream level. Host, charger, charging cable, remote control, manual, and extra mini tripod.
The overall machine is square, with a touch panel area on the top glass panel, and a power switch on the red pattern in the lower right corner. The middle frame is made of aluminum alloy material, and the front is made of milky mirror glass material. The combination of glass and metal and the white tone of the front face are quite beautiful and textured.
Body size is 10x10x62.5px, how small, multi-pocket level, the following comparison to see
Compared with the mainstream portable micro-projection meter in the market, the size of the meter is only half the size of a meter.
Smaller than Android game box
Put together with MX5
This is far smaller than the mainstream micro-projection, is also smaller than the Andrews box, PaPa micro-projection than the phone is small, from the size, called the pocket projection worthy of its name, then the weight, then take a look.
Bare metal to weigh it, 216.7 grams. Also put some references below, so that everyone understands the weight level more intuitively.
An MX5 phone with a tempered film is 159.4 grams.
The most portable micro-producer currently weighing 613.1 grams.
The weight of a mobile phone is also much lighter than that of a mainstream micro-projector. The overall size and weight of the official pocket cinema title are still well deserved. However, light weight also has its own advantages and disadvantages. It is light and lightweight, and it also causes instability in the projection, and it is easy to touch.
Touch the red power switch on the top. After the hidden touch area lights up for a few seconds, it can be turned on for a few seconds. This may be to prevent accidental touch, but the operating experience is not smooth enough. , but it can be opened by remote control a key.
The front touch button area is very eye-catching at night.
The front of the machine is the lens and the infrared receiving opening. The layout of the big one and the small one, whether it feels like a big eyes and a small eyes, the sprouting expression? The only thing unsatisfactory is the black plastic ring outside the lens, which is contrary to the overall delicate design.
With a few strokes added, this PaPa has no resemblance to a selling robot. =
Close-up of the lens area, consulting official customer service reply glass lens, not resin. Unlike other products, the lens is concave in depth, and the outer 2 layers of the frame that looks like they have protective lenses are actually lensless. The lens outer border plastic material processing should be the biggest regret on the appearance.
Or the first display technology, Taobao on a lot of cheap projectors are eliminated single-chip LCD technology, the principle is similar to previous slides used in teaching, the advantages are low cost, but poor light transmission, light energy conversion rate It is not high, and the projected image is also blurred and not recommended. The current mainstream display technology should be 3LCD and DLP. This DLP technology refers to reflective projection technology, a solution that uses optical semiconductors to produce digital multi-light source displays. Reflective DMD device applications, and PaPa is using this DMD device, LED light source, DMD size is larger theoretically the better, PaPa is using DLP 0.3†DMD EM technology, just another home micro-projection with home Naturally, it will bring contrast behind it, and it will not irritate the eyes with refracted light.The advantage of DLP is good contrast and uniformity, sharpness, and sharp colors.PaPa officials may know that their brightness is not a selling point at all, so they are more vague. With less than 2000 lumens, the response is 450 lumens after consultation, according to the LED projection international standard is actually 100ansi lumens.Looking at the LCD kind of light bulb lumen parameters of thousands of start, there are many users may be as worried about this lumen is enough, At the back of the meeting, the actual viewing contrasts.Despite the obvious advantages of the DLP technology of Texas Instruments, it has a long life, lower power consumption, and no maintenance costs such as light bulbs.
Run a question, I hope that more domestic and foreign manufacturers can develop similar technologies to promote the replacement of projection, after all, a good light bulb price and maintenance threshold is still relatively high, currently only a Texas Instruments DLP technology in the projection In the transformation, we are able to play a leading role in the competition. We can have more competition and promote technological development, which will benefit both manufacturers and users.
Return to the product and look at the back of the machine. From left to right are the headphone jack, TF card slot, USB2.0 jack, RESET hole, and microusb power hole. The PaPa's portable streamlined approach is more aggressive, perhaps because of the real portable definition and actual resolution considerations, so it does not come with an HDMI input. If you want to transfer computer operation screens, you can extend the wireless display to the projector via WiDi (compatible with Miracast). If some computer hardware does not support it, you can use other network-based screen software, but the transmission efficiency may not be so good. If you also want to display and control the computer in reverse through projection? The same can be! Install a remote control software, such as sunflower remote control, can both view the mode and control the computer. The specific effects can also be seen in my accompanying video evaluation section.
In addition Microusb power hole also has the same data transmission function, and the same phone, through the data line connected to the computer can read the data, the default is to turn on the USB debugging, if the computer does not respond, you can go to the projection settings / USB / connection Go to the PC and switch back and forth.
The side of the machine next to the infrared is provided with a row of air outlet holes for heat dissipation, and the actual noise and heat generation under such a small body will be tested later.
The side of the lens that is next to the lens is designed to have its own speaker opening, which will also bring about the speaker's specific effects. The right side of the speaker is a focus dial for adjusting the sharpness. The feeling of dial shifting is too thin, too easy to over-push, it is recommended to increase the appropriate damping effect is conducive to precise adjustment, if you can later change to machine auto focus, the overall design will appear more advanced.
Even with real pocket-level portability, there is still a screw connector that keeps the tripod at the bottom (plugging Tucao: Since this is preserved, you also cut the HDMI port, =. =), and there are several rows of thermal inlets on the side. Consider To a small size, placed easily moved, there are non-slip footpad design around.
PaPa's standard remote control is fully white, with very comfortable color schemes and key layouts. Functions are categorized into maximised categories, which are Power, Direction, OK, Back, Home, Menu, and Volume. The keystrokes are moderate, but the feedback is slightly dry. And my right button on this desk feels a weak feedback. I do not know how long life can be.
This remote control is infrared, not the common 2.4Ghz remote control box, but it is not imaginary insensitive, basically the direction is correct, can easily respond to remote control.
In addition, the CR2032 button battery is used for remote control. For the first time, open the battery compartment first and unplug the plastic gasket.
Compared with other micro-projection remote control and Android box, it can be described as the most compact remote control, with the least functionality.
Standard power adapter. Shenzhen Qixin foundry, looked at the parameters for the 5V-2A, power and mobile phone charging head is almost the same, the mainstream of the charging head is basically compatible.
The plug is slightly larger than the ordinary mobile phone charger, but it is petite in the micro-investment.
In addition, the standard power cord feels very comfortable, but the length is too short, shorter than other micro-investments, may also be due to the product for the pocket level considerations, made a modest streamlining.
The PaPa is more generous than the usual micro-projections. It also comes with a portable mini desktop tripod. The official website quotes 39 yuan. Amount, to be honest does not feel so much.
Because of the rough material material and I used to send a mobile phone clip to a treasure 9.9, but the details are still slightly better. After all, you don’t want to pay for it alone. Many occasions are still very practical. It's easy to adjust the height and direction, which is more convenient than adding or subtracting things on the table. However, the PaPa is too small. When adjusting the angle and direction during projection, it is also very attractive.
Hardware description
The Rockchip RK3188 chipset from Rockchip used by PaPa (using a 28nm quad-core master chip with a quad-core A9 architecture). This chip was released at the end of the 12th year. It is believed that PaPa uses it on the one hand for cost considerations, on the other hand It is also out of the current more stable and mature program. PaPa is equipped with a 1G ram, and the performance running point is certainly not a bright spot. It is similar to a TV box, but it is enough to handle normal video playback.
In addition, after the actual test of the audio in the video, the conclusion was barely enough. Because, after all, the volume is small, only a speaker, the sound is relatively thin, there is a mixed phenomenon, a person to see the movie barely enough, if the pursuit of better results, it is recommended that external speakers or headphones. The video evaluation part attached to this article has a reference comparison of the various devices. (PaPa's built-in storage comes with a veil of Faye Wong's rush that year. Faye Wong's voice is more ethereal, so the sense of thinness may not be too obvious. He clapping and applauds Pa Pa's wit, but the effect is still unsatisfactory.)
Get started
In the introduction of projection parameters in the market, you will generally see that there are two kinds of indicators: standard resolution and highest compatible resolution. The standard resolution refers to the actual physical resolution of the product. PaPa is 854×480, which is the machine. The best supported resolution. The maximum compatible resolution refers to the maximum compatible resolution of the machine. Although PaPa can support the 1080P hard solution, the picture is actually compressed when the 1080P resolution video is played, even if the PaPa plays 1080p video. The actual output projection display is also 480p.
The official parameters did not specify the throw ratio, and the consulting customer service responded with a more intuitive answer: 2 meters can project 74 inches, and 3 meters can project 100 inches. Next mainly based on 2 meters of test screen.
Turning on the projector for the first time, it took about 1 point to reach the system successfully after turning on the power.
There is no first-time novice to boot, the first boot directly into the desktop, the desktop is based on the Android 4.4 custom PaPa UI (officially the original is a deep customization of the PaPa UI, but personally feel that is not enough depth, will be mentioned later). The Metro block design is still somewhat rough for designers with obsessive-compulsive disorder. The shape and color of the homepage icon, as well as the choice of the default background, can also be considered. Moreover, the current flat style is not an absolute plane and rejection of the sense of body, but should be restrained modest use of light and shadow, even if the solid color can also be designed to integrate a three-dimensional visual sense. The degree of customization of the desktop can only count the initial stage of the TV version of the launcher.
The most common boxes and projections I use are video, live, and resource managers. Let's take a look at the PaPa's own film and television. Open it is actually a pre-installed film, and users of the TV box in the early days will not be too strange. Unfortunately, the old version of Tai Jie is currently blocked by radio and television, this pre-installed can not be opened, must update the latest 4.X version.
The television in the desktop is actually a TV cat. Fortunately, the TV cat survived the last round of radio and television raids. Even if the new version is not updated, it can be directly used to test the factory-installed old version to order several movies and videos. TV channels are broadcast live.
The file manager uses the white and white file manager. Many people should be familiar with it. The interface is relatively simple and easy to use. However, I encountered a problem here. I saved a file on one of my Toshiba NTFS U disks. I couldn't identify it in Xiaobai. I could only use another system's built-in resource manager to recognize it. White's own player has a very bad remote control experience. When you open the U disk video player with White, you cannot pause/play directly with the OK key. You cannot use the arrow keys to fast forward and backward.
The game center that comes with it is also pre-installed by a third-party grape game hall.
Out of 8 pieces of artifacts in the box to test the compatibility of the peripherals, actually perfect operation, just download a game can also be directly compatible, this is better than the other one at home, very m plug in No response. However, there are few games to play, and no professional handles are installed. 8 pieces of artifacts are demoed in the video.
The market that the average manufacturer pays more attention to is similar to the third-party Chippe market used in PaPa. It may be the first product of the initial stage. The development of its own APP has not kept pace with the use of third-party APPs. Fortunately, these are also used. Are more familiar, the user is more acceptable. This kind of benefit is surely to save a lot of costs, shorten the development cycle, and users are not difficult to get started, but the current direction of development, without its own soft power, is difficult to do for a long time.
Click on the system settings to enter the display of the second floor interface, there is a projection on the projection method, but unfortunately there is no ordinary projection common upper and lower trapezoidal correction. Saying that this "settings" APP actually comes with it, but it is a native Android system settings interface, this platform for remote control operation, the interaction is not easy to use, first use, first when connected to wifi Tired, completely failed to achieve the official so-called deep customization, after a long period of turmoil in the television box after a long period of turmoil, theoretically mature experience and technology in the industry should be sufficient to use smart lithography, PaPa software development has yet to continue efforts .
In addition to the fact that PaPa did not have a complete interaction and custom app, the more native system has a good side. Near-native Android is more suitable for geeks. Use the mouse to draw a status bar from the bottom. After opening the screenshot shortcut button in the settings, you can click on the screenshot in any interface. It is also possible to draw the top bar down from the top. (PS: The right mouse button responds to the return action in this system. Pressing the left mouse button on the icon of the desktop is equivalent to the long press operation in the phone, which can trigger more options, such as uninstalling the app.)
In the upper right corner of the standard interface, no specific power is displayed. Sometimes it is not convenient to view. Use the mouse to drag down the right side of the top bar. You can see the percentage of power.
Back to the desktop, switch to the application tab and see that many applications are pre-installed. Wukong Remote Control is very practical, making up for the shortcomings of mobile remote control assistants who do not have their own. Others that are useful to me should also be WPS.
PaPa is very interesting and pre-installed security Bunny. In this case, open up and see. Previously introduced U and configuration, so this score is also reasonable.
There are not many applications built into the system. Multi-screen interactions exist in the form of independent APP portals. For example, this WifiDisplay, which is Miracast on mobile phones, is very effective under test, and basically has no delay. The same is also shown in the video evaluation section. In addition, native Andrew Dafa is very good, very conscientiously retains Google Play store, you can easily house better toss.
There is another independent resource manager, although the interface is much less than the pre-installed white manager, but the compatibility is much better. The previously mentioned white manager can't read and use the U disk. Can display and operate normally.
After watching the normal use of the APP in the background of the occupancy and storage situation.
Picture measurement
Return to the actual projection screen and test the grayscale display of the next screen. Test environment: Night bedroom lights, 70-inch screen. The actual viewing effect can always be resolved to the second upper left.
Opened the bedside lamp, 70-inch screen real shot effect
The same night off lights, 70-inch screen real shot effect (ignore the corner of the night light)
Real shot part
Continue to enlarge the part, you can see different from the conventional rectangular arrangement, PaPa is a diamond arrangement, this method has both advantages and disadvantages, the same level, the diamond for watching movies, imaging better, but for the text display is still rectangular The arrangement is better, but the physical resolution of the 480P is basically not used to project computer content. If it is a large-size PPT, it does not matter, so in this regard, PaPa can be understood using a diamond arrangement.
Fine text display under diamond arrangement.
In addition, most of these types of micro-projections have a small number of centers and edges that cannot be clearly focused at the same time. Under normal circumstances, they are all based on the definition of the middle region.
Move out another brightness comparison with the same size as the smart microprojection. It can be seen that either the brightness or the color reproduction performance is lacking.
During the day, the PaPa projection effect under the curtain is still on the right, which is basically not suitable for viewing.
However, under the same conditions during the daytime, this ultra-portable micro-projection effect is even better than PaPa, but overall it is equally satisfactory.
This is PaPa's projection of a 100-inch screen at night. The effect can only be said to be reluctant, and the experience will be much worse. The projection size increases as the projection distance becomes larger, but the brightness decreases as the distance increases. The distance is certainly the brightest, but there is no large-scale shock, so in general, personally feel that Pa01 It is appropriate to project 50 to 70 inches at night or in the darkest possible environment.
Life testThe official announcement announced that the PaPa has a built-in 3000mAh battery and the battery life is 2 hours and 30 minutes. However, how about the specific battery life? I made a simple statistics before and after.
Full battery life test began, played a 1 hour 34 minutes of 720P/MP4 video, 9:30 to 11 points more. After the play is finished, the remaining battery power is 20%. It is estimated that the actual broadcast situation can barely be sustained for 2 hours. Of course, it may be related to different environments.
Continue to test the picture under full power and play life, use the slide feature of the own white file manager to rotate the picture, rotate back and forth more than 200 pictures multiple times. After 30 minutes, it dropped from 100% to 60%. It seems that opening a short few people will only demonstrate what the slide should be enough.
But don't be afraid to use the built-in power projection outdoors, although the battery life is limited, but the charging standard is 5V, 2A, so it also supports the same power of the mobile power supply (there are tests below), you can safely put aside the power plug in the outdoor projection.
Charging test
Received the goods to test the charging efficiency. For the first time, I could not open the machine. I charged it directly for the first time. By the way, I started counting from 10:30 in the morning until 17:00 in the afternoon. It took a total of 6 hours and 30 minutes. It feels too slow. And when the power is off, the power is only about 3 to 4W, which is very low.
Then, a second charge test was conducted. When the battery was discharged to the remaining 10%, it began to charge. From 11 am to 5:30 pm, it was full, 10% to 100% for a total of 6 hours... The speed is really flattering.
Only when the projector is turned on for power supply, the power is improved, as shown in Figure 7W. I hope that I can achieve a fast charge later, or else I have been dragging the line. This is also called pocket cinema.
Mobile Power Compatibility Test
In the case of a projection operation, the mobile power supply adapter is tested. A 5V-2A output port of a not-known second-line mobile power source of a certain treasure successfully supplies power to the mobile power source, and the power is maintained between 6 and 7 W.
Switch to a mobile phone with music bubble found that can not afford to supply power, the test found that when the PaPa power supply, the voltage is too low, only 4V, resulting in normal charging.
For another Meizu mobile power, it seems no pear, successfully rushed into the PaPa being projected.
Most 5V, 2A mobile power supplies can power the PaPa, but there may be some incompatibility. We must first pay attention to the use of mobile power to charge the PaPa.
Heat test
Many people are worried about fever. With such a small machine, there will be no problem with heat. Here is a simple test. At this moment, in the winter and the south, the temperature at room temperature is 10 degrees. After 30 minutes of projecting a 720P video, the front temperature is less than 30 degrees.
The back temperature is up to 33 degrees. The test results are quite satisfactory, but the temperature should be higher in the air-conditioned room.
Noise test
Place the phone on the side of the outlet hole test (the video is temporarily muted during playback) and place the phone in close contact with the loudest area. The maximum is about 60dB, but if people stand on the edge, almost no sound can be heard, plus the sound when playing the video, there is no need to worry about the cooling fan noise problem.
In addition, regarding the life, the theoretical use time is 20,000 to 30,000 hours, and the maximum life span of the traditional projection standard mode is 3000 hours, which is more than 10 times. According to someone on the Internet, using 8 hours per day is sufficient for 10 years. At this time, it may be said that the brightness of the LED projection attenuation?
Data indicate that there is no significant attenuation in the first 5,000 hours of the LED (half the decay rate of conventional light bulbs for more than 500 hours). Therefore, even if the actual playing brightness, the network and other different environmental factors affect, there will be no problem in three to five years, and according to the current development speed of smart micro-projection, do not wait until 10 years, in fact, less than 5 years, I believe you have eliminated the replacement of bamboo tube Better projection. So the lens is no longer the bottleneck of current LED projectors.
Insufficiency/suggestions:Resolution is less than 720P, 1080P is not expected, the current bandwidth is not really enough smooth, but 720P always
· lack of HDMI input, perhaps only 854 × 480 resolution, think the computer desktop input can not see the word in the past?
1G is only shipped, although the pro version of the latter has 2G, but also hope that 2G should be started as a standard in the future
· Lumen is still low, 100 lumens of Ann's lumens, probably translated into the lumen of the domestic light bulb statement is only about 450.
There is no keystone correction, although other projections I rarely use the correction, but at some times it is more convenient
· No 3D function, now home DLP micro-projection has many 3D features, but also a good selling point
· The built-in speaker is too thin, and the level of customization can only be heard. I hope to improve it later in the budget considerations.
·The system is still in the initial stage of customization. Today, the interactive experience is more important, PaPa needs to continue to work hard.
·Top touch keys often fail, and need to be lifted by both hands to work (similar to the symptoms of early capacitive screen phones)
·Unplugged and plugged in the power plug, there have been several automatic restart phenomenon, also hope that the firmware update to improve the repair later
Advantages/Highlights:TV box size, but contains TV box + smart system + projection
· Built-in power supply and Android system, convenient location, direct projection
Top touch panel function, direct operation without any remote control
·The tripod hole is added to the bottom of the tiny micro-projection.
· In addition to being small, it's really lightweight, and the weight of a mobile phone is more
Low power, outdoor support extended battery life through mobile power
Final summary:Built-in power supply, compact size to surprise you, built-in android system, etc., inherited the traditional projection function, and changed the people's views on the projector. Perhaps there is still a gap between hardware indicators and professional micro-investment, but PaPa's current positioning determines that it is not a substitute for the living room TV, nor is it the use of Blu-ray and advanced audio enthusiasts to play things, but pay more attention to the real portable Sexuality, audiences are often out of office to demonstrate the PPT report staff anytime, anywhere, or to rent out the weapon for renters who are away from home, as well as the Tim Happiness when playing travel. PaPa for ordinary users, is already a surprise digital new playthings, as the young man's first projection is also good, and PaPa brings the new direction of home projection, and later with the PaPa and similar manufacturers update , The real pocket-level projection to replace the home TV is not out of reach. And other highlights, after the implementation of short focal spot, can not be turned into a mobile computer, the future can go anywhere in this projection box with a U disk, then the mouse and keyboard, turn the power projection WPS office to become new the trend of.
At present PaPa is still a product of this company, looking forward to the second generation to ensure compact at the same time, improve the resolution to the definition and the appropriate bandwidth of the mainstream 720P level, increase the Angle of lumen to 200 or so, increase the dust protection cover is almost Although the next year, DLP technology applications under the home smart projection estimated to start the 1080P level, but PaPa is doing differentiated market segmentation, so 720P is still sufficient for portable positioning. In addition to continuing to increase hardware and process accidents, it should also continue to improve its own soft power at the same time. The customization UI is not deep enough. Basically, no user experience is optimized. Many details have not yet been implemented. There is almost no content provision. These are still the PaPa still have to work hard. Local, accelerating and genuine content providers should seek greater development, and should carry their own market platforms, and they should try to do content and avoid ecosystems instead of just being a hardware provider. At present, PaPa hardware is not very good in the field of micro-investment and is not a selling point of PaPa. In addition, many encountered some details of doubts or problems, I went to the Internet search, it is difficult to find the answer, QQ group is very inactive, Jingdong / Taobao's official customer service for the pure use of the details of the consultation and not to buy the user is not enough enthusiasm, community Forum long time did not update, the same way it paste it and other channels, many wait and see users see the forum are advertising, see it is not active, and the official website is not online customer service page, which will inevitably lead the user will think that the brand no one to use , after sales not to force the impression. Today, fan marketing and after-sales service are important.
From PaPa's point of view, it should be more detailed in its positioning. The dimensions in the portable space have indeed been achieved, but what is next to continue to upgrade hardware as a selling point? Or optimize system customization first? Or to enlarge the price to sell it? Or to increase after-sales service and related services? Users naturally hope that they will all achieve it. However, if the capacity of emerging companies is limited and they cannot achieve all-round development, they should first improve their ability to be the first. Avoid the current configuration is not high, soft power did not keep up with the embarrassment. Of course, this is PaPa's first product, perhaps it should not be so harsh, I believe it can do better in the future.
Purchase suggestion:When you come to see it again, many people are waiting for this sentence: For the user who is watching and buying the first introductory projector for home TV, my personal suggestion is, not recommended! It does not replace television. If you're a wandering dweller, you don't have a place to put TV. Using PaPa to take a look at the walls to see the movie is also a way to improve the quality of life. You can travel and entertain your family and share your photos and videos in the evening! Love to play digital, as long as it is not cast fire class, it will definitely be interested in such a small PaPa. The PaPa's flagship crowd should also be these now! At present, the lowest 1200 on the Internet is being sold. For the same price, it is harder to find such a portable and attractive projection. If people who are still too expensive can wait for a meeting, they should be around 1000 years later, and they will be more cost-effective and able to walk. It is believed that the competition for smart micro-investment in the next 16 years will be even more intense, and the entry-level version will also enter the price range of 999 units just like the domestic thousand-yuan machine.
In addition, due to price, configuration and positioning, individuals do not recommend PaPa users to re-provision professional curtains, and direct projection of white walls is sufficient.
