Seamless splicing screen refers specifically to a large LCD splicing screen that can achieve 0mm splicing display. Although it does not make the LCD panel borderless, it eliminates the effect of the splicing on the screen display through later technical means, and also maintains the advantage of the LCD screen's high-definition resolution, so that the display effect of the entire large screen can be improved.
Seamless splicing technology is a special and relatively demanding projection display application that can achieve the fusion of multiple screen images and minimize the splicing gap to the point of complete overlap.
Seamless splicing technology not only requires a complete ultra-large screen, but also has special requirements for the projection used to project an ultra-large screen.
The biggest difference between seamless splicing technology and BSV LCD splicing technology is that the gap is small. The main technical advantages are presented as follows:
1. Completely solve the visual defect of the splicing large screen image being divided and achieve complete seamlessness
Looking at the current large-screen splicing system in my country, many display screens still have a lot of splicing seams during work.
For example, the gap of 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 visual effect, there are still a lot of dividing lines.
Even if LCD, DLP, and PDP technologies are applied in engineering, the gap can only be reduced, but not completely eliminated. Seamless LED splicing technology can completely solve the problem of screen segmentation and achieve the requirement 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 needs of users for close viewing.
Compared with existing splicing technologies, LED physical seamless splicing can achieve cross-screen display. For the splicing seam, the level does not depend on the size of the gap, but whether the gap exists.
2. Completely solve the problem of inconsistent brightness and chromaticity attenuation of spliced large screens
The application of seamless LED technology will effectively deal with the situation of different brightness and chromaticity attenuation of spliced large screens. In this technology, point-by-point brightness and color correction technology is generally used, which ensures the uniformity of brightness and color.
For example, the application of point control technology creates a platform for users to correct color and brightness point by point, and control the pixels of the screen to achieve high 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 time.
3. Intensive display and control platform, handle all monitoring video sources
Seamless LED technology uses an intensive display and control platform to ensure the reliability of monitoring video sources, create a management platform for customers, and effectively realize the management of video signals, computer signals, and network signals, providing users with better services.
4. Widely used, can be installed both outdoors and indoors
LED splicing screen is often used in various fields and industries because of its lightness, excellent quality and effect, and the price of LED display screen is also moderate. If it is more advanced in the future, its coverage will be wider! Moreover, the environmental adaptability of LED screen is extremely strong. After a little waterproof treatment, it can meet the requirements of outdoor use, even if it is exposed to wind and sun.
5. Powerful redundant backup design of power supply and signal to ensure safe and reliable use
In the design of seamless LED system, the redundancy of power supply and signal is backed up, which can reduce the occurrence of problems during its use.
6. Super long life, simple maintenance process, ultra-low maintenance cost
Compared with general display screens, LED has a longer lifespan, and its maintenance and repair costs are relatively low.
7. High brightness and adjustable
The brightness of LED screen is much higher than that of LCD, so when it is displayed outdoors, even when facing the sun, the LED screen can display the content normally without any reflection. At the same time, it can be manually adjusted according to the brightness of the installation environment. For example, the brightness can be adjusted on the sunny side and the shady side to adapt to the display under different brightness.
8. Ultra-large viewing angle, ultra-high contrast, ultra-high refresh rate
The project provides a large viewing angle and prevents the occurrence of reflection. When capturing the picture, the state is relatively stable. It can respond to dynamic display pictures, the image edges are clear, and it has good dynamic expression, and the image information is 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 display screen is excellent, and the single-point brightness correction is carried out to make the brightness uniformity of the entire screen tend to the extreme.
9. Ultra-thin, ultra-light structure, ultra-quiet heat dissipation processing technology
In the application process of seamless LED splicing technology, ultra-quiet heat dissipation processing technology is also used.
10. Dynamic energy saving, ultra-low power consumption, green light source, energy saving and environmental protection, pollution-free
In actual application, 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 screen is working, it generates different power consumption as the picture changes; that is, it is equivalent to a part of the peak power consumption, generally between 30% and 50%; it varies depending on the display content; when the traditional splicing large screen is working, no matter what the picture 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, pollution-free products: Due to its luminous materials and working principles, pollution-free traditional splicing large screens will have various environmental pollution sources such as mercury, ultraviolet rays, and auxiliary radiation. LED high-definition display products are directly luminous, and the LCD light source is the backlight bulb (tube). Its luminous medium is mostly tungsten, lead, etc., which has no significant impact on the environment.
In summary, seamless splicing technology is another major leap forward in the LED display industry. It comprehensively solves the seamless splicing defects that other display devices cannot complete. At the same time, it can also achieve energy saving and environmental protection, intensive display, and increase service life. It is an indispensable technology in the LED industry.
