LED high-definition display seamless splicing technology
Seamless splicing technology
Seamless splicing technology is a special and relatively demanding projection display application, which can realize the fusion of multi-screen images and reduce the splicing gap to a minimum so as to completely overlap the splicing technology. The seamless splicing technology not only requires a complete super large screen, but also has special requirements for the projection used to project the super large screen. The biggest difference between seamless splicing technology and BSV LCD splicing technology is the small gap.
Practical application of seamless LED splicing technology in engineering
1. Completely solve the visual defect of splicing large screen images and achieve complete seamlessness
In the current large-screen splicing system, many display screens still have more splicing seams during work. For example, the liquid crystal splicing system, the gap is too large to meet the needs of users; while the plasma and rear projection large screen splicing system has many advantages compared with the liquid splicing splicing technology, but from the perspective of its visual effect, there are still a lot of dividing line. Even if LCD, DLP, and PDP technologies are applied in engineering, the gap can only be reduced, but cannot be completely eliminated. 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-up viewing. Compared with the existing splicing technology, LED physical seamless splicing can realize cross-screen display. For patchwork, the level of its level is not the size of the gap, but the existence of the gap.
2. Completely solve the problem of inconsistent brightness and chroma attenuation of splicing large screens
The application of seamless LED technology will effectively deal with the situation of different brightness and chromaticity attenuation of splicing large screens. In this technology, point-by-point luminance and chromaticity correction techniques are generally used, which ensures the uniformity of luminance 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.
3. Intensive display and control platform, get all monitoring video sources
The seamless LED technology uses an intensive display and control platform to ensure the reliability of monitoring video sources, build a management platform for customers, and effectively realize the management of video signals, computer signals, and network signals, providing users with better service.
4. Powerful redundant backup design of 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. Super long life, simple maintenance process, super low maintenance cost
Compared with the general display screen, the service life of LED is longer, and its maintenance and repair costs are relatively low.
6. Large viewing angle, ultra-high contrast ratio, ultra-high refresh rate
The project provides a larger viewing angle and prevents the appearance of reflections. When taking pictures, the state is relatively stable. In response to dynamic display pictures, the edges of the images are clear, with good dynamic expression, and the image information can be accurately and truly restored. Make the video picture delicate and smooth, bringing 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 carried out to make the brightness uniformity of the whole screen tend to be extreme.
7. Ultra-thin, ultra-light structure, ultra-quiet heat dissipation technology
In the application 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 the actual application process, the highway seamless LED splicing technology can reduce energy consumption and save engineering costs. It is highlighted 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 is generated with the change of the picture; that is, it is equivalent to a part of the power consumption required for the peak value, which is generally between 30% and 50%; it depends on the display content; the traditional splicing large screen When working, regardless of the content of the screen, 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 will have various sources of environmental pollution such as mercury, ultraviolet rays, and auxiliary radiation due to their luminescent materials and working principles. The LED high-definition display screen directly emits light. The LCD light source is a backlight bulb (tube), and its light-emitting medium is mostly tungsten, lead, etc., which has no major impact on the environment.
To sum up, the seamless splicing technology is another great leap forward in the LED display industry, which comprehensively solves the defects of seamless splicing that other display devices cannot complete, and at the same time can achieve energy saving, environmental protection, intensive display, and long service life. It is an indispensable technology in the LED industry.
