Seamless splicing technology
Seamless splicing technology is a special and demanding projection display application that can realize the fusion of multi-screen images and minimize the splicing gap 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 a 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. Thoroughly solve the visual defect caused by segmentation of large-screen splicing screens, and achieve complete seamlessness
Looking at the large-screen splicing system in my country at this stage, many displays still have more splicing seams in their work. For example, the LCD splicing system has too large gaps to meet the needs of users; while plasma and rear projection large-screen splicing systems have more advantages than liquid splicing technology, but in terms of their visual effects, there are still a lot of advantages.的分线。 The dividing line. Even if LCD, DLP, and PDP technologies are used in engineering, they can only reduce the gap, but cannot completely eliminate them. 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 increase the screen resolution in a small area, ensure the quality 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 splicing, its level is not the size of the gap, but the question of whether the gap exists.
2. Thoroughly solve the problem of inconsistent brightness and chromaticity attenuation of spliced large screens
The application of seamless LED technology will effectively handle the situation where the brightness and chromaticity attenuation of the spliced large screen are different. In this technology, point-by-point brightness and chroma correction technology is generally used, which ensures the unity of brightness and chroma. For example, the application of point control technology creates a platform for users to correct chromaticity and brightness point by point, and to control the pixels of the screen to achieve a high degree of image restoration. This technology has both SMS and E-mail prompt functions, which can enable users to grasp the status information of the splicing wall in time.
3. Intensive display and control platform to handle all surveillance video sources
The seamless LED technology uses an intensive display and control platform to ensure the reliability of surveillance video sources, create a management platform for customers, and effectively realize the management of video signals, computer signals, and network signals to provide users with better service.
4. Power and signal powerful redundant backup design to ensure safe and reliable use
In the design of the seamless LED system, the redundancy of the power supply and the signal is backed up, which can reduce the occurrence of problems during its use.
5. Ultra-long life, simple maintenance process, ultra-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. Ultra-large viewing angle, ultra-high contrast, ultra-high refresh rate
In the project, a larger viewing angle is provided, and the occurrence of light reflection is prevented. When the picture is taken, the state is relatively stable, and it can respond to the dynamic display of the picture. The edge of the image is clear, and it has good dynamic expressiveness, which can accurately and truly restore the image information. Make the video screen delicate and smooth, and bring the greatest visual enjoyment. In addition, it is particularly pointed out that the brightness uniformity of the LED screen is excellent, and the brightness uniformity of the whole screen tends to the extreme with the single-point brightness correction.
7. Ultra-thin, ultra-light structure, ultra-quiet heat dissipation processing technology
In the application of seamless LED splicing technology, ultra-quiet heat dissipation technology is also used.
8. Dynamic energy saving, ultra-low dynamic 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, it will produce different power consumption as the picture changes; that is, it is equivalent to a part of the peak power consumption, which is generally between 30% and 50%; it depends on the display content; traditional splicing large screen At work, 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, environmentally friendly, pollution-free products
Non-polluting 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 the product, 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.
In summary, the seamless splicing technology is another great leap forward in the LED display industry. It fully solves the seamless splicing defects that other display devices cannot complete. At the same time, it can achieve energy saving and environmental protection, intensive display, and increase the service life. And other characteristics, is an indispensable technology in the LED industry.
