Abstract

The present invention discloses a liquid crystal display device, which comprises a liquid crystal panel and a flexible printed wiring board electrically connected with the liquid crystal panel; a drive chip is arranged on the liquid crystal panel, and is covered by the flexible printed wiring board. A metal conducting layer on the flexible printed wiring board of the liquid crystal display deviceis served as a metal radome of the drive chip, which effectively prevents external static electricity flowing through the drive chip, simultaneously effectively solves the technical problems that thedirve chip can not work or be damaged caused by the electromagnetic interference generated by the drive chip itself.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] In recent years, liquid crystal display devices have gradually occupied the mainstream of display products due to their advantages of light and thin, small space occupation, and low radiation. In a liquid crystal display device, the liquid crystal panel itself does not emit light, but the backlight module provides it with uniform planar light. [0003] The liquid crystal panel includes an upper glass substrate and a lower glass substrate and a liquid crystal layer sandwiched between the two glass substrates. The lower substrate of the glass substrate includes a driver IC, which is used to drive the liquid crystal panel to control the luminous flux supplied by the backlight module, so as to display images with rich colors. The driver chip is fixed on the LCD panel by COG (Chip On Glass) technology, and a black light-shielding tape is attached to the driver chip to ...
