Splicable large-size liquid crystal display device and process method thereof

Abstract

Provided in the invention is a splicable large-size liquid crystal display device comprising an upper frame, a lower frame and a side frame. The side frame serves as a splicing side frame of the display device and is used for transverse splicing of a plurality of display devices, wherein the width of the splicing side frame ranges from 0.6 mm to 0.8 mm; the upper frame and the lower frame or one of the upper frame and the lower frame is a conductive side frame, wherein the width of the conductive side frame is 1.5-2.0 mm. And a liquid crystal filling port of each display device is arranged atthe edge of the spliced side frame and is adjacent to the conductive side frame. In-box lining materials of a liquid crystal box of each display device are evenly distributed in the density range of 30 to 50 pieces per square millimeter, and the lining materials in the liquid crystal box are formed by mixing 5.0-5.5 microns of white silicon ball hard powder and 5.5-6.0 microns of black plastic soft powder. The width of the splicing side is very small, and the splicing side can be transversely and seamlessly spliced for use; and meanwhile, the position of the filling port is redesigned to adaptto the width of the splicing side. And the large-size liquid crystal display also enables a problem of non-uniform bottom color caused by overall change of the box thickness when the outdoor temperature is changed to be solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a splicable large-size liquid crystal display and a process method thereof. Background technique [0002] In recent years, LCD (Liquid Crystal Display) has been more and more widely used in daily life due to its advantages of high contrast, low power consumption, and small size (ultra-thin), especially in instruments, household items, and car dashboards. and other fields. We often see liquid crystal displays for notification in the waiting halls and platforms of many domestic and foreign railway stations and bus stations. However, due to the limited display area and few display contents of a single liquid crystal display, the usual method in this field is to splice a series of large-size (about 300*400mm) liquid crystal displays horizontally, and to achieve seamless splicing as much as possible. [0003] Such as figure 1 As shown, the frame of the existing larg...
