The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen

LCD brightness Brightness represents the amount of brightness of a picture per unit area. Specifically, the density of the amount of light passing through the normal direction of the screen. The unit is [CD / m2] or nit（1 nit = CD / m2).Brightness depends on the amount of light passing through the LCD and color film, and the brightness of the backlight.   LCD backlight requirements: The liquid crystal should have good transmittance; light weight; It should be thin and not easy to damage; The area light source with uniform brightness is the best; Low cost; The light color is pleasing to the eye, the primary color is rich, and the brightness can be adjusted; Low power consumption and easy power supply

As the COVID-19 epidemic breaks out all over the world, all walks of life are suffering from the impact of the epidemic, and the LCD industry has also suffered a cold winter, and demand has fallen sharply. The epidemic is a new test for the entire LCD panel industry chain. In previous years, at the China Import and Export Fair, twice a year, you could see people from all over the country going to Guangzhou to participate in the exhibition. But this spring, compared to face-to-face cooperation negotiations in the exhibition hall, all advertisers and LCD purchasers had to find another way to negotiate this year’s market cooperation projects. All LCD companies in Shenzhen have a problem in survival in such a big environment. It is understood that due to the impact of the epidemic, sales staff of many companies keep product prices low in order to place orders, but do not consider whether the quality of product accessories is satisfactory, which added many unnecessary after-sales problems to buyers. In other words, while pursuing low prices, we also need to pay for the quality problems caused by low prices. We hope everyone chooses carefully.
