How to Realize Seamless Stitching of LED Display Screen

Author: From: Time: 2019-07-04

 At this stage, due to the 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 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, the technicians of the display terminal have improved the existing technology and made it develop towards seamless and high-definition. Then, seamless jointed high-definition LED display emerges as the times require.

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. Solving the visual defect of spliced picture

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 the inconsistency between brightness and chroma attenuation of spliced large screen

The application of seamless LED technology will effectively deal with the situation of different brightness and chroma attenuation of mosaic 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.

3. Intensive Display and Control Platform

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. Design of Redundant Backup with Powerful Power Supply and Signal

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

5. Extra-long life, simple maintenance and ultra-low cost

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

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

The project provides a larger viewing angle and prevents the appearance of reflective phenomenon. When capturing a picture, the state is relatively stable, and the image edge is clear and has good dynamic expression, so the image information can be accurately and truly restored. Make the video picture delicate and smooth, bring the greatest visual enjoyment. In addition, a special point is put forward that 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. Handicraft of Ultra-thin, Ultra-light Structure and Ultra-silent Heat Disposal

In the process of using seamless LED splicing technology, super silent heat dissipation technology is also adopted. 

8. Static energy saving, ultra-low power consumption, green light source, energy saving and environmental protection.
