Detailed Explanation of Seamless Mosaic Technology for LED HD Display Screen

In order to further improve the monitoring technology and data collection, the technicians of display terminals have improved the existing technology, so that it can develop seamlessly and high-definition. Immediately, seamlessly stitched HD LED display screen came into being.

Seamless Stitching Technology

Seamless stitching technology is a special and demanding projection display application. It can fuse multi-screen images together and reduce the stitching gap to the minimum so that the stitching technology can completely overlap. Seamless stitching technology requires not only a complete super-large screen, but also special requirements for projection of super-large screen. The biggest difference between seamless splicing technology and BSV liquid crystal splicing technology lies in the small gap.

Practical application of seamless LED splicing technology in Engineering

1. Solve thoroughly the visual defect of splicing large screen images and realize seamless.

Throughout the large screen stitching system in our country at present, there are still many stitching seams in the work of many display screens. For example, LCD splicing system, the gap is too large to meet the needs of users. Compared with liquid splicing technology, plasma and back projection large screen splicing system has more advantages, but there are still a large number of segmentation lines in terms of its visual effect. Even if lcd, DLP and PDP technology are applied in engineering, the gap can only be reduced, but can not be completely eliminated. But the seamless led stitching technology can make the screen segmentation problem thoroughly solved and achieve the requirement of complete seamlessness.

The seamless LED splicing technology can improve the screen resolution in a small area, ensure the texture of the screen, and meet the needs of users to watch at close range. Compared with the existing splicing technology, the physical seamless splicing of LED can achieve cross-screen display. For joints, the level of seams is not the size of seams, but the existence of seams.

2. Solve thoroughly the problem of inconsistent attenuation of brightness and chroma of spliced large screen

The application of seamless LED technology will effectively deal with the situation that the brightness and chroma attenuation of mosaic large screen are different. In this technology, the point-by-point brightness and chroma correction technology is generally used, which ensures the unity of brightness and chroma. For example, the application of point control technology creates a platform for users to correct the chroma and brightness point by point, and controls the pixels of the screen to achieve the height restoration of the image. This technology also has the function of short message and e-mail prompt, which enables users to grasp the status information of the splicing wall in time.

3. Intensive display and control platform, so as to make sure all monitoring video sources

The application of seamless LED technology in intensive display and control platform ensures the reliability of monitoring video sources, creates a management platform for customers, and effectively realizes the management of video signals, computer signals and network signals, and provides better services for users.

4. Redundant backup design with powerful power supply and signal to ensure safe and reliable operation

In the design of seamless led system, the redundancy of power supply and signal is backed up, which can reduce the problem in the use process.

5. Super-long service life, simple maintenance process and ultra-low maintenance cost

Compared with the general display screen, the life of LED is longer, and its maintenance and maintenance costs are relatively low.

6. Ultra-large viewing angle, ultra-high contrast, ultra-high refresh frequency

The project provides a larger viewing angle and prevents the appearance of reflective phenomena. When capturing a picture, the state is relatively stable, and the dynamic display screen should be dealt with. The edge of the image is clear and the dynamic expression is good. The image information can be accurately and truly restored, which makes the video picture delicate and smooth and brings the greatest visual enjoyment. In addition, the brightness uniformity of the LED screen is excellent, and the brightness uniformity of the whole screen tends to the extreme with single point brightness correction.

7. Ultra-thin, Ultra-light Structure, Ultra-silent Heat Dissipation Technology

In the application of seamless led splicing technology, super-silent heat dissipation technology is also used. Chinese style

8. Dynamic energy saving, ultra-low power consumption, green light source, energy saving and environmental protection, pollution-free
In the actual application process, the seamless led splicing technology of expressway can reduce energy consumption and save engineering cost. Highlighted in the following two aspects.

(1) Low-power and energy-saving technology

When the LED high definition display wall works, it produces different power consumption with the change of the picture. That is to say, the power consumption equivalent to the peak value is generally between 30% and 50%. The display content is different. Traditional mosaic large screen maintains a constant power consumption, i.e. the required power, regardless of the content of the screen, even if the screen is black.

(2) Energy-saving and environmental protection, non-polluting products

Because of its luminescent materials and working principle, the non-polluting traditional mosaic large screen will have various sources of environmental pollution, such as mercury, ultraviolet radiation, auxiliary radiation and so on. Led high-definition display direct light-emitting products, LCD light source is backlight bulb (tube), its light-emitting medium is mostly tungsten, lead and so on, which has no significant impact on the environment. To be careful

In summary, seamless splicing technology is another great-leap-forward progress in the LED display industry, which comprehensively solves the seamless splicing defects that other display devices can not complete, and can also achieve energy-saving, environmental protection, intensive display, increase service life, etc. It is an indispensable technology in the LED industry.
