Liquid crystal display panel binding method and structure

Abstract

The invention provides a liquid crystal display panel binding method and structure. The liquid crystal display panel binding method is that fusion metal material or conductive glue material is applied to the side surface and the upper surface of a TFT substrate to form a conductive pattern connected with a lead wire; and then conductive pattern and a flip-chip thin film can be bond when anisotropic conductive adhesive film is arranged on the side surface of the TFT substrate. The process is simple; a binding area is arranged on the side surface of the TFT substrate, so compared with a binding method of arranging the binding area on the upper surface of the TFT substrate, liquid crystal display panel narrow frame display and narrow frame tiled display can be achieved; and unfavorable effects due to the bend of the flip-chip thin film can be effectively avoided. The liquid crystal display panel binding structure can be achieved by the use of the above binding method; the binding area is arranged on the side surface of the TFT substrate, so liquid crystal display panel narrow frame display and narrow frame tiled display can be facilitated.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a bonding method of a liquid crystal display panel and a bonding structure of a liquid crystal display panel. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module (Backlight Module). The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires betwee...

Figure 5 Schematic diagram of bonding structure for existing LCD panels, such as Figure 5 As shown, in the bonding structure of the liquid crystal display panel, the edge of the upper surface of the TFT substrate 310 is provided with a bonding area 315, and metal leads 600 are distributed in the bonding area 315, and the metal leads 600 pass through the anisotropic conductive adhesive film (Anisotropic Conductive Film, ACF) 700 is bonded to the chip-on-chip film 400. In this liquid crystal display panel bonding structure, since the area of ​​the bonding region 315 on the upper surface of the TFT substrate 310 is relatively large, it needs to be bonded outside the liquid crystal display panel. Set a wider border to cover the bonding area 315, so that it is difficult to achieve a narrow border display
