In recent years, with the development of the security industry and the improvement of display technology, people have higher and higher requirements for visual images. The visual impact and the quality of the displayed image have become the standard for people to judge the display performance. The visual effect not only comes from a clear image, but also depends on the size, brightness and contrast of the screen. The traditional LED display can no longer meet the market demand. In order to meet this demand, LCD splicing screen manufacturers have emerged.
The English abbreviation for outdoor LED display is LCD or DID. The splicing display unit is adopted, and the splicing screen body with full-screen or split-screen display effect is realized through the large-screen control software system. Its core component is the LCD panel. Currently, South Korea, Samsung and LG are the main panels on the market, while BOE and AUO are domestic panels. The main sizes in the outdoor LED display market are 46 inches, 47 inches, 55 inches and so on. The mainstream splicing is about 3.5 mm, the smallest is the LG 55-inch splicing screen, and the bilateral splicing is only 1.8 mm. In China, LCD splicing screen manufacturers are mainly in Guangdong, Shandong, Zhejiang, and other places. Mainstream brands include Haikang, Dahua, Youse Special Display, and so on.
