LCD display module and display device for improving sealing performance of adhesive side

Abstract

The invention relates to an LCD display module and a display device. A piece of surface ITO conductive glass, a piece of bottom ITO conductive glass, a packaging adhesive side frame body, a liquid crystal layer, an orientation assembly and a polaroid assembly are arranged. With an avoidance area, when the LCD display module is packaged, one side of the packaging adhesive side frame body is connected with the edge of the surface ITO conductive glass and the other side of the packaging adhesive side frame body penetrates the avoidance area and is connected with the bottom ITO conductive glass. Since the surface ITO conductive glass and the bottom ITO conductive glass are made of same manufacturing materials, the sealing performance is good. The connecting forces between the packaging adhesive side frame body and the surface ITO conductive glass and between the packaging adhesive side frame body and the bottom ITO conductive glass are same; when an external force is applied to the extension part, the surface ITO conductive glass and the bottom ITO conductive glass are not separated mutually and thus direct damages of the LCD display module are avoided, so that the overall mechanical strength of the LCD display module is enhanced and the service life of the LCD display module is prolonged.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to an LCD display module and display equipment. Background technique [0002] At present, a liquid crystal display, or LCD (Liquid Crystal Dispaly), is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, and is placed in front of a light source or a reflective surface. Liquid crystal displays consume very little power and are therefore favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. The working principle of liquid crystal display: Liquid crystal is a special substance between solid and liquid. It is an organic compound, which is liquid under normal conditions, but its molecular arrangement is as regular as solid crystal, so it is named liquid cry...

Problems solved by technology

However, due to the coating of TOP insulation protection, please refer to figure 1 , figure 1 It is a schematic diagram of the internal structure of the LCD display screen 20 of the prior art, from figure 1 It can be seen that the glue frame 23 must be connected with the TOP insulating protective layer on the surface glass substrate 21 and the bottom glass substrate 22, which is easy to cause a problem, because in the actual use of the LCD display, it is necessary to pass through the bottom glass substrate. The extended end 24 of 22 inputs an external signal, if the extended end 24 of the bottom glass substrate 22 is subject to a large external force, it will cause the surface glass substrate 21 and the bottom glass substrate 22 to separate from each other, directly damaging the LCD display screen 20, because the surface glass substrate 21 and the TOP insulating protection layer are made of different materials, so that the connection force will not be different when the glue frame 23 is connected to these two, resulting in the extension end 24 of the bottom glass substrate 22 being subjected to a relatively large external force, and the front glass substrate 21 and the bottom glass substrate 22 are separated from each other and damage the LCD display screen 20. The overall mechanical strength of the LCD display screen 20 adopting the above structure is low. When the extension end 24 of the bottom glass substrate 22 is subjected to a large external force, the LCD display screen 20 will be directly damaged. Later maintenance Cost and replacement costs are quite high
