At this stage, as China's monitoring technology level and data collection capacity have been improved to a certain extent, whether the display terminal can accurately present the collected data on the display wall in time is very important, which directly relates to the rationality of the decision-making of the superior departments. In order to meet the market demand, the technical personnel of science and technology improved the company's original technology splicing technology, making it develop towards seamless and high-definition. Then, the seamless splicing LED display came into being.
Seamless splicing technology is a special and demanding projection display application, which can realize the fusion of multi screen images and minimize the splicing gap so that it is completely coincident. Seamless splicing technology not only requires a complete ultra large screen, but also has special requirements for the projection used to project ultra large pictures. The biggest difference between seamless splicing technology and BSV liquid crystal splicing technology is that the gap is small.
1. Completely solve the visual defect of splicing large screen images to achieve complete seamless
Looking at the current large screen splicing system in China, there are still many splicing seams in the work of many display screens. For example, the LCD splicing system has too large gap to meet the needs of users; Plasma and back projection large screen splicing systems have more advantages than liquid splicing technology, but there are still a large number of segmentation lines in terms of their visual effects. Even if LCD, DLP and PDP technologies are applied in the project, the gap can only be reduced, but can not be completely eliminated. The seamless led splicing technology can completely solve the problem of screen segmentation and achieve the requirements 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, the level is not the size of the joint, but whether the joint exists.
2. Completely solve the problem of inconsistent brightness and chrominance attenuation of splicing large screen
The application of seamless led splicing technology will effectively deal with the different brightness and chroma attenuation of the spliced large screen. In this technology, point by point luminance and chrominance correction technology is generally used, which ensures the unity of luminance and chrominance. For example, the application of point control technology creates a platform for users to correct chromaticity and brightness point by point, and controls the pixels of the screen to realize the high restoration of the image. This technology also has the functions of SMS and e-mail prompt, which can enable users to grasp the status information of the splicing wall in time.
3. Intensive display and control platform, all monitoring video sources
Seamless LED technology applies an intensive display and control platform to ensure the reliability of monitoring video sources, create a management platform for customers, and effectively realize the management of video signals, computer signals and network signals, so as to provide better services for users.
4. Powerful redundant backup design of power supply and signal ensures safe and reliable use
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.
5. Long service life, simple maintenance process and low maintenance cost
The service life of LED display screen is longer than that of general display screen, and its maintenance and repair costs are relatively low.
6. Large viewing angle, high contrast and high refresh rate
The LED display provides a large viewing angle in the installation project, and prevents the occurrence of reflective phenomenon. When the picture is taken, the state is relatively stable. In response to the dynamic display picture, the image edge is clear, with good dynamic expressiveness, and the image information is accurately and truly restored. Make the video picture delicate and smooth, and bring the greatest visual enjoyment. In addition, it is especially pointed out that the brightness uniformity of LED screen is excellent. With the single point brightness correction, the brightness uniformity of the whole screen tends to the extreme.
7. Ultra thin, ultra light structure and ultra quiet heat dissipation technology
In the application of seamless led splicing technology, the ultra quiet heat dissipation technology is also adopted.
8. Dynamic energy saving and ultra-low power consumption
