Description

Spliced display module and spliced screen Technical Field The application relates to the technical field of display, in particular to a spliced display module and a spliced screen. Background The Liquid crystal display (Liquid CRYSTAL DISPLAY, LCD) device is the display product which is most widely applied in the market at present, the production process technology is very mature, the product yield is high, the production cost is relatively low, and the market acceptance is high. At present, the requirements of various oversized display screens are increasing, the application of the oversized display screens is also becoming wider, and the integrated manufacturing process of the oversized display screens is difficult and high in cost due to the limitation of the process, so that the spliced screen technology is an effective way for realizing the oversized display devices. For example, two liquid crystal display devices are spliced together to form a spliced screen, but the formed spliced screen has a splicing gap, so that the visual effect is affected.
