On July 25th, the "Foreground 20** China Industry Forum" hosted by Prospect Consulting was held in Shanghai as scheduled. With the high temperature of more than 40 degrees, the "warmness" of the entire forum meeting continued to soar, attracting many top global leaders. The equipment manufacturers performed product demonstrations and guest speeches, and nearly 400 professional AV professionals in Shanghai came to listen to the study and exchange, and discussed the future development direction of the AV (Audio Video) industry.

At the invitation of the organizer, Beijing Huanyu Lanbo Technology Co., Ltd. (abbreviation: LANBO), as a guest speaker, mainly discussed the "display new technology, and strive to solve the pain points of users," and discussed and discussed the advantages and disadvantages of display products. At the same time, it brought disappointing display product flat panel projection: Athena series and Apollo series, both independently developed by LANBO, and obtained patents for invention products. One of the main visual screens on this conference site used the LANBO flat panel projection. The display was well received by the visitors.

What are the "black" technologies in flat panel projection?

The projection circle has been the subject of discussion is the light source and brightness, how to change the type of light source to provide the brightness of the projector, from 1000ANSI lumens to 20000ANSI lumens brightness, or even higher; Is the projector is not enough light? Even if the projector reaches tens of thousands of lumens, why does the display still not satisfy you? As long as the lights are on or the curtains are opened, the projection screen cannot be read. Do not believe. Look at the picture.

In fact, the fundamental reason is that the projector is not "black". To understand this problem, you need to understand the projector's important technical indicator "contrast". The definition of contrast is very simple: it is the value of "white divided by black" if " The value of "black" is relatively large, and then the value of "white" is so large that it cannot fundamentally solve the problem of high contrast. (We do not discuss the test standard differences of ANSI and ISO contrast here)

Where did the "black" go?

There are two aspects that affect the projection screen without the "black" factor:

1 The projection screen is white or gray. From the aspect of imaging angle, there will be no “black” screen, and the color saturation will also be affected. This will lead to the need to turn off the curtains when artificially used the projector, and artificially create a "Black" house environment.

2 The projector's own imaging principle determines that even if the screen is black, the light source of the projector is still on, and there will be excess light projected from the projector's light path. When the black screen is finally presented, it is actually doped with bright light. There is no way to form true black.

If it is the use of high-end conference or classroom environment, the scene needs to ensure sufficient brightness, it can not be a "black" house, so the display effect is far from satisfactory.

The flat panel projection independently developed by LANBO is based on the “grid pixel projection” technology. Each pixel is an independent projection unit. The distance from the light source to the screen is less than 3mm, there is no complicated light path, and there is no need to calculate the brightness loss of the light path projection. , Low power consumption can ensure sufficient brightness, and will not interfere with adjacent display pixels at the same time, ensuring that the screen "black" color rendering, to achieve a high contrast effect;

Small pitch LED display screen bright and glare eye problems have been controversial is relatively large; LANBO flat screen projection surface protection of the patented screen, after the point light into a surface light, ensure the continuity of the picture pixels, make it reach a high Bright and soft display screen, and effectively prevent the problem of blue light radiation at 460nm, the third-party inspection report shows that the value of blue radiation at 460nm is less than 1/10 of OLED TV, OLED TV has been known as no blue light damage, then Flat-panel projection is even safer.

While ensuring the safety of the screen-facing person, the user can touch the screen at random and also protect the screen from being hurt by external forces, thereby realizing the safety of the person against the screen.

Big data display:

LCD TV radiation brightness: 0.6339W/m2·sr·nm*

OLED TV radiation brightness: 0.1441W/m2·sr·nm*

LANBO flat panel projection radiance: 0.0135W/m2·sr·nm

At the same time to meet the needs of many people watching, the screen size must be large enough, and the current large-size stitching screen, whether it is DLP, LCD, LPD or edge fusion, visual patchwork has always been the culmination of the splicing screen, and LANBO flat screen projection screen is Continuous display, so that the entire screen display effect does not have a visual patchwork, as shown below, can you see that it is a mosaic screen?

The main visual screen of this forum is the 173-inch Apollo series. Its ultra-thin structure can be moved, which greatly saves the use of space on the spot. It is flexible and flexible. Its realistic display effect and soft high-definition picture become the forum's focus;

At the entrance of the Forum Hall, LANBO also displayed the 145-inch flat panel projection of the Athena series. Compared with the Apollo series, the number of display pixels increased by 44% per square meter in terms of pixel display. In the same display size, the Athena series displayed more images. Delicate and better.

The debut of the LANBO flat panel professional AV forum, the new display method, and excellent display effect caused a great sensation on the scene, and the on-site participants also had a great interest in the flat panel projection.

Strive to solve the pain points and bottlenecks encountered by large-size display products, LANBO is still on the road to continuous innovation.
