Liquid display device

Abstract

The invention discloses a liquid display device. The liquid display device comprises a back light module, a liquid crystal panel and a chip on film, wherein the backlight module is composed of a lightemitting surface and a back surface opposite to the light emitting surface; the liquid crystal panel is arranged on the light emitting surface of the backlight module, and the front surface of the liquid crystal panel, which backs to the backlight module, is provided with a signal binding end; the chip on film is composed of a flexible circuit board, a binding unit and a driving chip, the bindingunit and the driving chip are arranged on the first surface of the flexible circuit board, the flexible circuit board is electrically connected to the signal binding end through the binding unit andis bent to extend towards the back surface of the backlight module; in the part of the flexible circuit board which is bent to extend towards the back surface of the backlight module, the first surface of the flexible circuit board comprises a first area back to the backlight module, and the driving chip is connected inside the first area. The liquid display device can reduce influence of heat generated by the backlight module on the driving chip, thereby improving the reliability of the driving chip.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] Among flat panel display devices, Liquid Crystal Display (LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, and occupies a dominant position in the current flat panel display market. [0003] A chip on film (COF) is a driving unit used in a liquid crystal display device, and is usually attached and bonded to the edge of the liquid crystal panel by means of heat and pressure. With the continuous advancement of display technology, display products with narrow bezels (Narrow Bezel) have attracted a large number of consumers because they can enable users to obtain a better viewing experience. In order to obtain a liquid crystal display device with a narrow frame, it is usually necessary to bend the COF from the side of the liquid crystal panel to the b...

AI Technical Summary

Problems solved by technology

During the operation of the liquid crystal display device, the driver chip itself will generate a large amount of heat radiation, and the backlight module will also generate a large amount of heat radiation. If the distance is very small, the heat radiation generated by the backlight module and the heat radiation generated by the driver chip will superimpose, which will make the temperature of the driver chip too high

The driver chip is an important part for transmitting and processing signals. If its temperature is too high, it will affect the stability of the working performance, which will reduce the reliability of the driver chip and even cause the driver chip to be damaged due to overheating.
