At this stage, as my country's monitoring technology level and data collection ability have been improved to a certain extent, whether the LED display terminal can accurately display the collected data on the display wall in a timely manner is very important, which is directly related to the decision-making of the superior department. rationality. In order to meet the needs of the market, the technicians of the display terminal improved the existing technology and made it develop in the direction of seamless and high-definition.
Seamless splicing technology is a special and relatively demanding projection display application, which can realize the fusion of multi-screen images and minimize the splicing gap to completely overlap. The seamless splicing technology not only requires a complete super large LED 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. So how does the LED electronic display and the LCD liquid crystal display achieve seamless splicing? Next, the editor of Liancheng will introduce you one by one!
1. Seamless splicing technology of led electronic display
(1) Solve the visual defect that the splicing screen is divided
Looking at the current large-screen splicing system in my country, many LED displays still have more splicing seams in their work. For example, in the LCD splicing system, the gap is too large to meet the needs of users. Compared with liquid splicing technology, plasma and rear projection large-screen splicing systems have many advantages, but from the perspective of their visual effects, 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 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)Solve the inconsistency of splicing large screen brightness and chroma attenuation
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. This technology has both SMS and E-mail prompt functions, which can allow users to grasp the status information of the video wall in time.
(3)Intensive display and control platform
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 for power supply and signal
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)Long life, easy maintenance, low cost
Compared with the general display screen, the service life of LED is longer, and its maintenance and repair costs are relatively low. The LED display screen produced by Lianchengfa provides a larger viewing angle during the installation project and prevents reflection. When the picture is captured, the state is relatively stable, and the picture should be displayed dynamically. The edge of the picture is clear, with good dynamic expression, so that 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 makes the brightness uniformity of the entire screen tend to be extreme.
(6)Ultra-large 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 and ultra-light structure, ultra-quiet heat dissipation technology
In the application process of seamless LED splicing technology, Lianchengfa LED display also adopts ultra-quiet heat dissipation technology.
2. LCD liquid crystal display splicing technology
The basic concept of optoelectronic device splicing LCD splicing screen is to assemble a distinctive optical laser lens operation panel body on a general 3.5mm operation panel, and the basic concept of line-of-sight projection based on the wired glass, so that the original page looks divided. According to the optical laser lens, it is not difficult to see in an image, and the seam with the black edge can not be seen at all, completing the patchwork in the visual impact.
(1) The joints use full-screen LED electronic components to display the picture quality compensation, and use optical laser lenses and optoelectronic devices to project the basic concept of piecing together.
(2)The image resolution pitch of the picture quality correction of LED electronic components is less than 1.5mm, so that most people cannot see the gap.
(3)The LED that pays for the picture quality of the electronic components adopts the professional SMD logo, and does not use the large particle lamp-like display, which promotes the softer lighting and weakens the damage caused by the visual impact of the gap.
(4)After the picture quality of the LED electronic components is corrected, the edge of the light-transmitting condensing lens is widened to make the LED light source softer and closer to the primary color of the liquid crystal display.
To sum up, seamless splicing technology is another major leap forward in the LED display industry, which fully solves the seamless splicing defects that other display devices cannot complete, and at the same time can achieve energy saving, environmental protection, intensive display, and increased use. Longevity and other characteristics are indispensable technologies in the LED industry.
