At this stage, due to the led video wall improvement of monitoring technology and data collection ability in China, it is very important to show whether the terminal can accurately present the collected data on the led display wall in time, which is directly related to the rationality of decision-making of higher authorities. In order to meet the needs of the market, technicians improved the company’s original technology splicing technology, making it seamless, high-definition direction of development, and then, seamless splicing LED display panel came into being.
Seamless stitching technology is a special and demanding projection display application, which can realize the fusion of multi-screen images and reduce the stitching gap to the minimum so as to completely coincide with the stitching technology. Seamless stitching technology not only requires a complete super large screen, but also has 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.
1. Solve thoroughly the visual defect of splicing large screen images and realize complete seamlessness.
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; and plasma and back projection large screen splicing system has more advantages than liquid splicing technology, but from its visual effect, there are still a large number of segmentation lines. Even if LCD, DLP and PDP technology are applied in engineering, the gap can only be reduced, but can not be completely eliminated. Seamless LED splicing technology can completely solve the problem of screen segmentation and achieve the requirement of seamless.
Using seamless LED splicing technology, the screen resolution can be improved in a smaller area, ensuring the texture of the screen, and meeting 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 brightness and chroma attenuation of spliced large screen
The application of seamless LED splicing technology will effectively deal with the situation of different brightness and chroma attenuation of splicing large screen. 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.
