Liquid crystal display device

Abstract

The invention discloses a liquid crystal display device, which comprises a lower frame, a backlight module, a shading adhesive tape, a liquid crystal panel and an upper frame. The backlight module is arranged in the lower frame, the shading adhesive tape consists of a bottom edge and a side edge, the bottom edge is attached to the backlight module, the side edge is attached to a side surface of the lower frame, the liquid crystal panel is arranged on a surface, with the lower frame, of the shading adhesive tape, the edge of a surface of the liquid crystal panel is attached to the bottom edge of the shading adhesive tape, the peripheral edge of the liquid crystal panel is attached to the side edge of the shading adhesive tape, and the upper frame is covered on the liquid crystal panel and combined with the lower frame. The backlight module and the liquid crystal panel are covered and carried by the metal lower frame, the shading adhesive tape with a flanging structure prevents light from leaking, an adhesive frame structure of a traditional liquid crystal display device is omitted, a design trend of light weight, thinness and short and small size of the market is met, material cost and manufacturing working hours are reduced.

Description

technical field [0001] The invention relates to the technical field of a display, in particular to a liquid crystal display device which reduces material costs and manufacturing man-hours. Background technique [0002] Generally, the existing liquid crystal display devices in the industry are mainly composed of a liquid crystal display module and a backlight module. Please refer to figure 1 A schematic structural view of a conventional liquid crystal display device is shown, the liquid crystal display device 100 includes an upper frame 101, a liquid crystal panel 102, a double-sided adhesive tape 103, a plastic frame 104, an upper prism sheet 105, and a lower prism sheet 106 , a diffuser 107, a light guide plate 108, a reflector 109 and a lower frame 110, one side of the light guide plate 108 is provided with a light source (not shown), the liquid crystal panel 102 is glued to the The plastic frame 104 forms a liquid crystal display module 111, and the upper prism sheet 105...

AI Technical Summary

Problems solved by technology

[0003] 1. The plastic frame 104 is usually a "mouth"-shaped rectangular frame, so it takes up a lot of internal space in the lower frame 110, resulting in the volume and weight of the liquid crystal display device 100 being unable to be effectively reduced, and unable to meet the light, thin, short, and small design in the market trend

[0004] 2. Using the plastic frame 104 to carry the liquid crystal panel 102 is an existing technology traditionally adopted in the industry. Since the industry has little difference in the injection molding capabilities of the plastic frame 104, it cannot be significantly different from the industry in terms of module thinning and narrow margin design. Competitiveness

[0005] 3. The mold cost of the plastic frame 104 is high and the mold opening time is long

Therefore, it seriously affects the development schedule and increases the cost
