At this stage, as my country's monitoring technology level and data collection capabilities have been improved to a certain extent, it is very important whether the display terminal can accurately present the collected data on the display wall in a timely manner, which is directly related to the rationality of the superior department's decision-making. sex. In order to meet the needs of the market, the technicians of the display terminal improved the existing technology to make it develop in the direction of seamlessness and high-definition. Then, the seamless splicing high-definition LED display came into being.
Seamless splicing technology is a special projection display application with relatively high requirements, which can realize the fusion of multiple screen images and minimize the splicing gap to completely overlap. The seamless splicing technology not only requires a complete ultra-large screen, but also has special requirements for the projection used to project ultra-large images. The biggest difference between seamless splicing technology and BSV LCD splicing technology is that the gap is small.
1. Completely solve the visual defect of splitting large-screen splicing images, and realize complete seamlessness
Looking at the large-screen splicing system in my country at this stage, there are still many splicing seams in the work of many display screens. For example, the LCD splicing system, the gap is too large to meet the needs of users; while the plasma and rear projection large-screen splicing system has more advantages than the liquid splicing technology, but from the perspective of its visual effect, there are still a lot of problems. the dividing line. Even the application of LCD, DLP, and PDP technologies in engineering can only reduce the gap, but cannot completely eliminate it. The seamless LED splicing technology can completely solve the problem of screen segmentation and meet the requirements of complete seamlessness.
The use of 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 realize cross-screen display. For the seam, the level of its level does not lie in the size of the gap, but the existence of the gap.
2. Thoroughly solve the problem of inconsistency in splicing large screen brightness and chromaticity attenuation
The application of seamless LED technology will effectively handle the situation that the brightness and chromaticity attenuation of splicing large screens are not the same. In this technology, point-by-point brightness and chromaticity correction technology is generally used, which ensures the uniformity of brightness and chromaticity. 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 achieve a high degree of image restoration. This technology also has SMS and E-mail reminder functions, which can allow users to grasp the status information of the splicing wall in a timely manner.
3. Intensive display and control platform handles all surveillance video sources
Seamless LED technology applies an intensive display and control platform, which ensures the reliability of surveillance video sources, creates a management platform for customers, and effectively realizes the management of video signals, computer signals, and network signals, providing users with better service.
4. Powerful redundant backup design for power supply and signal to ensure safe and reliable use
In the design of the seamless LED system, the redundancy of power supply and signal is backed up, which can reduce the occurrence of problems during its use.
5. Ultra-long life, simple maintenance process, and ultra-low maintenance cost
Compared with ordinary display screens, LED has a longer service life, and its maintenance and repair costs are relatively low.
6. Super large viewing angle, super high contrast, super high refresh rate
The project provides a larger viewing angle and prevents the occurrence of reflections. When taking pictures, the state is relatively stable, and when dealing with dynamic display pictures, the edges of the images are clear, with good dynamic expressiveness, and the image information is accurately and truly restored. Make the video picture delicate and smooth, bring the greatest visual enjoyment. In addition, it is particularly pointed out that the brightness uniformity of the LED screen is excellent, and with the single-point brightness correction, the brightness uniformity of the entire screen tends to the extreme.
7. Ultra-thin, ultra-light structure, ultra-quiet heat dissipation technology
In the application process of seamless LED splicing technology, ultra-quiet heat dissipation treatment technology is also adopted.
8. Dynamic energy saving, ultra-low power consumption, green light source, energy saving and environmental protection, no pollution
In the actual application process, the highway seamless LED splicing technology can reduce energy consumption and save engineering costs. It is prominently reflected in the following two aspects:
(1) Low power consumption and energy saving technology
When the LED high-definition display wall is working, different power consumption will be generated with the change of the picture; that is, it is equivalent to a part of the peak power consumption, generally between 30% and 50%; it is different depending on the display content; the traditional splicing large screen When working, no matter what the screen content is, even if the screen is black, it still maintains a constant power consumption, that is, the required power.
(2) Energy saving and environmental protection, non-polluting products
Pollution-free traditional splicing large screens have various environmental pollution sources such as mercury, ultraviolet rays, and auxiliary radiation due to their luminescent materials and working principles. The LED high-definition display directly emits light to display products. The LCD light source is a backlight bulb (tube), Indoor Flexible Mesh Curtain (resources) and its light-emitting medium is mostly tungsten, lead, etc., which has no significant impact on the environment.
To sum up, seamless splicing technology is another great leap forward in the LED display industry, which comprehensively solves the seamless splicing defects that other display devices cannot complete, and at the same time can achieve energy saving and environmental protection, intensive display, and prolong service life And other characteristics, it is an indispensable technology for the LED industry.
