Abstract

The invention discloses a liquid crystal display device. The liquid crystal display device includes a driving chip, a backlight structure and a metal support part; the backlight structure includes a flexible printed circuit board, the flexible printed circuit board includes a luminous zone, and a plurality of light emitting diodes are arranged in the luminous zone; the flexible printed circuit board includes a first protruding end a second protruding end, the first protruding end includes at least one port for being electrically connected with the driving chip, and the second protruding end includes a conductive zone; a grounding wire surrounding the luminous zone is arranged on the flexible printed circuit board, the grounding wire is electrically connected with the conductive zone, and the conductive zone is electrically connected with the metal support part. According to the liquid crystal display device, static electricity around the backlight structure can be conducted on the metal support part of the liquid crystal display device, the risk is reduced that the light emitting diodes are broken down due to the static electricity accumulated on the flexible printed circuit board, and a good static electricity prevention effect can be achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to the field of liquid crystal display technology, and in particular to a liquid crystal display device. Background technique [0002] Liquid crystal display devices are more and more widely used in various fields related to display because of their advantages such as low power consumption, high resolution, and low cost. A liquid crystal display device generally includes a light emitting diode (Light Emitting Diode, LED) light bar as a backlight, and the LED light bar is composed of a flexible printed circuit (Flexible Printed Circuit, FPC) and LEDs welded on the FPC. [0003] When the driving chip of the liquid crystal display device supplies power to the LED, static electricity is likely to be generated. The existing LED light bar has no grounding design, and the generated static electricity will accumulate on the LED light bar, causing the LED to be damaged, and then ...
