At this stage, as China ’s level of monitoring technology and data collection capabilities have been improved to a certain extent, it is very important for the display terminal to accurately display the collected data on the display wall in a timely manner, which directly affects the rational decision-making of the superior department. Sex. In order to meet the needs of the market, the technicians of the display terminal improved the existing technology and made it develop towards the direction of seamless and high-definition. Then, the seamless high-definition LED display technology came into being.
Seamless stitching technology is a special, highly demanding projection display application that can achieve multi-screen image fusion together and reduce the stitching gap to the smallest so that it completely overlaps the stitching technology. The seamless stitching technology not only requires a complete ultra-large screen, but also has special requirements for the projection used to project an oversized picture. The biggest difference between seamless stitching technology and BSV LED power supply technology is the small gap.
Practical application of seamless LED splicing technology in engineering
1) Completely solve the visual defect of the large screen splicing and achieve complete seamlessness
Throughout China’s current large screen splicing system, many display screens still have more splicing seams in their work. For example, the LCD splicing system is too large to meet the needs of users; while plasma and rear projection large screen splicing systems have more advantages than liquid splicing technology, but from the perspective of their visual effects, there are still a large number of Dividing line. Even if the LCD, DLP, and PDP technologies are applied in the project, the gap can only be reduced, and it cannot be completely eliminated. The seamless LED novastar vx4u splicing technology can completely solve the problem of screen segmentation and achieve the requirements of complete seamlessness.
The use of seamless LED splicing technology can improve the screen resolution in a smaller area, ensure the texture of the picture, and meet the user’s needs for close viewing. Compared with the existing splicing technology, LED physical seamless splicing can achieve cross-screen LED display service. For patchwork, the level is not the size of the gap, but whether the gap exists.
2) Completely solve the problem of inconsistent brightness and chroma attenuation of the large screen
The application of seamless design for LED technology will effectively deal with the situation where the brightness and chroma attenuation of the large screen are different. In this technique, point-by-point luminance and chrominance correction technology is generally used, which ensures the uniformity of luminance and chrominance. For example, the application of point control technology creates a platform for users to correct chroma and brightness point by point, and controls the pixels of the screen to achieve a high degree of image restoration. This technology has both SMS and E-mail reminder functions, which allows users to grasp the status information of the splicing wall in time.
3) Intensive display and control platform to handle all surveillance video sources
Seamless LED technology uses an intensive display and control platform to ensure the reliability of surveillance video sources, to create a management platform for customers, and to effectively implement the management of video signals, computer signals, and network signals, providing users with better service.
4) Powerful and redundant backup design to ensure safe and reliable use
In the design of the seamless LED system, the redundancy of the power supply and signals is backed up, which can reduce the problems during its use.
5) Ultra long life, easy maintenance process, ultra low maintenance cost
Compared with ordinary display screens, LEDs have a longer service life, and their maintenance and repair costs are relatively low.
6) Large viewing angle, high contrast, and high refresh rate
The project provides a large accessories viewing angle and prevents the occurrence of reflections. When capturing the picture, the state is relatively stable. It responds to the dynamic display picture, the edges of the image are clearance, and the dynamic expression is good, 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 the single-point brightness correction is used to make the brightness uniformity of the entire screen tend to be 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 processing technology is also used.
8) Dynamic energy saving, ultra-low power consumption, green light source, energy saving and environmental protection, no pollution
In actual application process, highway seamless LED splicing technology can reduce energy consumption and save engineering costs. It is prominent in the following two aspects:
1) Low power consumption and energy saving technology
The LED high-definition display wall generates different power consumption as the picture changes during operation; that is, it is equivalent to a portion of the peak power consumption, generally in linsn rv901t between 30% and 50%; depending on the display content, it is different; traditional large screen During work, regardless of the picture content, even if the screen is black, a constant power consumption is maintained, that is, the required power.
2) Energy saving and environmental protection, non-polluting products
No pollution The traditional splicing large screen will have various environmental pollution sources such as mercury, ultraviolet rays, and auxiliary radiation due to its light-emitting materials and working principles. The LED high-definition display directly emits display products. The LCD light source is a backlight bulb (tube), and its light-emitting medium is mostly tungsten, lead, etc., which has no significant impact on the environment.
To sum up, the seamless splicing technology is another big leap forward in the LED display industry, which comprehensively solves the seamless splicing defects that other display devices cannot complete, while also achieving energy saving and environmental protection, intensive display and increasing service life And other characteristics, is an indispensable technology for the LED industry.
