Liquid crystal screen and gate COF structure assembly and liquid crystal display device

Abstract

The invention relates to a liquid crystal screen and gate COF structure assembly and a liquid crystal display device. The liquid crystal display device comprises the components of a liquid crystal screen, gate COF structures which are arranged on the sides of the liquid crystal screen, a backlight module which is arranged behind the liquid crystal screen, and a front frame outside the backlight module; wherein one end of each gate COF structure is connected with the side of the liquid crystal screen and furthermore is bent from the side of the liquid crystal screen to the back surface of the liquid crystal screen, so that the other end of the gate COF structure is connected with the back surface of the liquid crystal screen. The backlight module is arranged behind the gate COF structures. The front frame is arranged outside the bent parts of the gate COF structures. The liquid crystal screen, the backlight module and the front frame form an accommodating space which is surrounded by the liquid crystal screen, the backlight module and the front frame and is used for accommodating the gate COF structures. The liquid crystal display device provided by the invention has advantages of compact structure design and small occupation space between the gate COF structures and the liquid crystal screen, so that an ultrathin and ultranarrow frame of the liquid crystal display device can be realized.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal screen-grid COF structural component and a liquid crystal display device. Background technique [0002] With the rapid development of liquid crystal display technology, it has become an industry development trend to provide liquid crystal display devices with thinner and thinner borders. Due to the limitation of the thickness and appearance of the display, if it is to achieve an ultra-thin and ultra-narrow bezel design, it is necessary to re-optimize the positioning structure of its components to make its structure more compact. [0003] Such as figure 1 Shown is a schematic diagram of the structure of the existing liquid crystal screen, in which a gate COF structure 2 (CHIPON FILM, often called chip-on-film) is arranged on both sides of the liquid crystal screen 1, and the driver IC is fixed on the flexible circuit board with the grain soft film structure ...

AI Technical Summary

Problems solved by technology

When this storage method is used, although the thickness of the backlight module is no longer limited by the grid COF structure, the display can be designed as an ultra-thin product, but the frame length of the entire liquid crystal display device is reduced due to the flat grid COF structure. Limited by the length of the gate COF structure, it is difficult to realize the design of ultra-narrow bezel display

[0006] It can be seen that in the existing liquid crystal display device, limited by the storage design of the gate COF structure, it is impossible to realize the ultra-thin and ultra-narrow bezel design of the liquid crystal display device at the same time
