How to realize seamless splicing of LED display文章来源：华云视界 发表时间：2021-06-04
LED display seamless splicing technology is a special projection display application with high requirements, which can realize multi screen image fusion, and reduce the splicing gap to the minimum so as to completely overlap. Seamless splicing technology not only needs a complete super large screen, but also has special requirements for the projection used to project super large screen. The biggest difference between seamless splicing technology and BSV liquid crystal splicing technology is the small gap.
Solve the visual defect of segmented mosaic picture
Throughout the current large screen splicing system in China, there are still many splicing seams in the work of many displays. 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 from its visual effect, there are still a lot of segmentation lines. Even if LCD, DLP and PDP technologies are applied in engineering, the gap can only be reduced, but not completely eliminated. The seamless led splicing technology can completely solve the problem of screen segmentation and achieve the requirement of complete seamless.
The seamless led splicing technology can improve the screen resolution in a small area, ensure the texture of the picture, and meet the needs of users for close viewing. Compared with the existing splicing technology, led physical seamless splicing can achieve cross screen display. For the joint, its level is not the size of the gap, but the existence of the gap.
Solve the inconsistency of brightness and chroma attenuation of splicing large screen
The application of seamless LED technology will effectively deal with the situation of different brightness and chroma attenuation of splicing large screen. In this technology, 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 chromaticity and brightness point by point, and controls the pixels of the screen to realize the high restoration of the image. This technology has the function of short message and e-mail prompt at the same time, which can let users grasp the status information of splicing wall in time.
Intensive display and control platform
Seamless LED technology applies intensive display and control platform to ensure the reliability of monitoring video source, build a management platform for customers, and effectively realize the management of video signal, computer signal and network signal, so as to provide better services for users.
Power and signal redundancy backup design
In the design of seamless led system, the redundancy of power supply and signal is backed up, which can reduce the problems in the use process.
Super long life, simple maintenance and low cost
Compared with the general display, LED has a longer service life, and its maintenance and repair costs are relatively low.
Super large angle, super high contrast, super high refresh rate
The project provides a larger viewing angle and prevents the reflection phenomenon. When taking pictures, the state is relatively stable, and the image edge is clear and has good dynamic expression, which can restore the image information accurately and truly. Make the video picture delicate and smooth, bring the greatest visual enjoyment. In addition, the brightness uniformity of LED screen is excellent, and the brightness uniformity of the whole screen tends to the extreme with the single point brightness correction。
To sum up, seamless splicing technology is another great leap forward in LED display, which comprehensively solves the seamless splicing defects that can not be completed by other display devices. At the same time, it can also achieve the characteristics of energy saving, environmental protection, intensive display, and increasing service life. It is an indispensable technology in LED industry.
