Now that the television industry has gradually entered the smart age, and smart TVs have become the mainstream, then what special attention should be paid to smart TVs compared with traditional TVs? The following is a guide to smart TV purchases, hoping to provide a little help for everyone.
Buying a smart TV screen is the key:
With the television entering the era of intelligence, the sources of video signals are becoming more and more high-definition, and the general LCD screen has been difficult to meet the demand for high-definition playback. Therefore, the high resolution of the screen resolution is an important indicator to judge the quality of the TV. 4k displays will gradually become Mainstream, another brand is also very important point, foreign 4k technology is more mature than domestic, import screen, Japan screen best (Sharp), South Korea screen next (LG friends, Samsung friends ~) but more common.
Smart TVs are more than televisions. They can also provide games, music and other services.
The interface is important:
USB interface and HDMI are common, the best is USB3.0 and HDMI2.0 faster, more advanced interface. The SD card slot is mainly used for directly inserting the camera's SD card to play pictures. SLR families have to consider this function.
Buy smart TV chip brand CPU is very important:
This point we should pay attention to, CPU is the core of smart TV, about the speed of smart TV system operation, it is very important. Just like a cell phone's computer, cpu is the soul of the TV. Without a good CPU, the smart TV will become stuck.
Smart TV dynamic picture technology:
Dynamic picture processing chip. As we all know, LCD TVs have a tail, and this technology for picture compensation has been used by many television companies. Some low-end products do not. Be sure to have ah, otherwise watching the game when the trailing screen is very difficult to tolerate. (See me a hundred thousand)
Smart TV memory and flash memory:
The main memory is the storage of data processed by the user. The larger the memory, the better, and the bigger it is, the more fluid it is.
The use of flash memory is to store APP, video pictures or music files, which is equivalent to a computer hard disk. The lowest is 8GB; the highest is now 32GB.
Buy smart TV energy consumption also need to consider:
Explains TV's power saving performance. General 50-inch TVs are rated at level 2 for energy efficiency. Level 3 energy-efficient ordinary products can be bought with caution, but it may be a relatively old model. However, it should be noted that the 4K display itself consumes more power, and the level 3 energy efficiency can be regarded as conventional energy consumption.
Is Wifi dual or single frequency:
Dual-band wifi is equivalent to adding one path to the single-frequency signal path. If your home network equipment is more, dual-band wifi function is very important. In general, three people at home have three or four mobile phones, a desktop, a notebook, a pad, and a TV.....
Does the smart TV have Bluetooth reception:
Bluetooth speakers, Bluetooth headsets, etc. If the TV has this function, it can be connected, especially when watching the game at night, with a Bluetooth headset, his own situation in the living room High is possible. (Otherwise, it's only a matter of high-tech) ~
Smart TV remote control:
First of all, ask if the remote control you use is not a standard one. Many brands of smart remote controllers are purchased separately. In addition, there is no basic function of the remote control and air mouse remote control, although it is Cool, but considering that the TV is a household product, the elderly is difficult to grasp, still have to consider carefully. Ordinary remote controls with arrow keys, numeric keys, mute keys, channel plus and minus keys, and setting keys are the best. Of course, everything is absolute. If you combine new technology and old keys, it is definitely the best design.
Buying a smart TV system is also crucial:
The smart TV is said to be a video-based computer. Since it is a computer operating system, it is of course very important. Nowadays, mainstream smart TV operating systems are developed based on Android. Some systems have strong compatibility. Some systems are The compatibility of customization will be almost, we should try our best to choose a compatible system, so that it is convenient to install third-party applications to expand our TV.
In fact, the selection of television is very simple, as long as you open the coat of the business, revealing the inner nature, know what is the focus of what is a girl, the other will not need me to say more ~ ​​Fire eyes, a see through the manufacturers of their TV in the end is not true The intentions. Only the manufacturers are interested in their products, we can buy them with confidence, you say it
PCB antenna is widely used in Bluetooth module, WiFi module, ZigBee module and other single-band module circuit boards.
Advantages: the cost is very low, a debugging without debugging again.
Disadvantages: suitable for single band, such as Bluetooth, WiFi. Different batches of PCB antenna performance will have certain deviation.

- The Description of PCB/FPC/Ceramic Antenna
Cellular /WiFi multi-band embedded flexible PCB antenna
It is equivalent to pulling out the antenna line on the PCB board and using other external metals to do the antenna. It is usually used in medium and low end mobile phones with complex frequency band and smart hardware products.
Advantages: suitable for almost all small electronic products, can do more than ten frequency band of complex antennas, good performance, low cost.
Disadvantages: need to be debugged separately for each product.
