The LED display seamless splicing technology is a special, relatively high-demand projection display application, which can realize splicing technology in which multi-screen images are fused together and the splicing gap is minimized to completely overlap. The seamless splicing technology not only requires a complete super-slim screen, but also has special requirements for the projection used for projecting an oversized picture. The biggest difference between seamless splicing technology and BSV liquid crystal splicing technology is the small gap.
1. Thoroughly solve the visual defects of splicing large-screen images and achieve complete seamlessness
Looking at the large-screen splicing system in China at this stage, many display screens still have more stitching seams in their work. For example, the liquid crystal splicing system has too large a gap to meet the needs of the user; and plasma and the rear projection large screen splicing system have more advantages in terms of the liquid splicing technology, but from the visual effect point of view, there are still a lot of The dividing line. Even if LCD, DLP, and PDP technologies are used in the project, only the gap can only be reduced and it cannot be completely eliminated. The seamless LED splicing technology can completely solve the problem of screen segmentation and achieve a completely seamless requirement.
With seamless LED splicing technology, the screen resolution can be improved in a small area, ensuring the texture of the screen and satisfying the user's need for close viewing. Compared with the existing splicing technology, LED physical seamless splicing can realize multi-screen display. For patchwork, its level is not the size of the gap, but the existence of gaps.
2. Thoroughly solve the problem of inconsistent brightness and chroma attenuation on large screens
The application of seamless LED technology will effectively handle the spliced large screen brightness and chroma attenuation is not the same situation. In this technique, point-by-point luminance and chroma correction techniques are generally used, which guarantees the uniformity of luminance and chrominance. For example, the application of point control technology creates a point-by-point correction platform for chromaticity and brightness, and controls the pixels of the screen to achieve a high degree of image restoration. This technology also has SMS and E-mail reminding capabilities, so that users can promptly grasp the status of the video wall.
3, intensive display control platform, get all monitoring video source
Seamless LED technology applies an intensive display and control platform to ensure the reliability of surveillance video sources, create a management platform for customers, and effectively implement management of video signals, computer signals, and network signals, providing users with better service.
4, Power and signal powerful redundant backup design, ensure safe and reliable use
In the design of a seamless LED system, backup of power and signal redundancy is performed, which can reduce the occurrence of problems during its use.
5, long life, simple maintenance process, low maintenance costs
The service life of the LED is longer than that of the general display, and its maintenance and maintenance costs are relatively low.
6, large viewing angle, high contrast, high refresh rate
The project provides a larger viewing angle and prevents reflections from occurring. When the screen is captured, the state is relatively stable, the dynamic display screen is handled, the edges of the image are clear, and the dynamic expression is good, and the image information is restored accurately and truly. Make the video screen smooth and smooth, bringing maximum visual enjoyment. In addition, a special point is made that the uniformity of the brightness of the LED screen is excellent, and the single-point brightness correction is coordinated, so that the uniformity of the brightness of the entire screen tends to be extreme.
7, ultra-thin, ultra-light structure, ultra-quiet cooling technology
In the process of seamless LED splicing technology, ultra-quiet thermal processing technology has also been adopted.
8, dynamic energy, 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. The highlights are reflected in the following two aspects:
(1) Low-power energy-saving technology
When the LED high-definition display wall is working, different power consumption is generated as the screen changes; that is, a part of the power consumption equivalent to the peak, generally between 30% and 50%; the display content is different; the traditional splicing large screen At work, regardless of the picture content, even if the screen is black, it maintains a constant power consumption, that is, the power required.
(2) Energy-saving and environmental protection, non-polluting products
Pollution-free traditional splicing large screens, due to their luminescent materials, working principles, etc., will have various sources of environmental pollution such as mercury, ultraviolet radiation, and auxiliary radiation. LED high-definition display direct light display products, LCD light source for the backlight bulb (tube), the luminescence medium is mostly tungsten, lead, etc., have no significant impact on the environment.
In summary, the seamless splicing technology is another leap-forward progress in the LED display industry, which fully solves the problems of seamless splicing that cannot be accomplished by other display devices, and at the same time, it can achieve energy-saving and environmental protection, intensive display, and increase the service life. Such features are an indispensable technology for the LED industry.
