Embodiment Construction

[0026] It can be known from the background art that the performance of the backlight module in the prior art needs to be improved.

[0027] A light bar is usually used as a light source in a backlight module of an existing display device, so as to provide a light source for the display panel. Light-emitting diode strips have become the preferred type of strips for display panel manufacturers because of their energy-saving and environmental protection properties. However, in the actual production process, the light-emitting diode lamp will be greatly affected by static electricity from the external environment. At the same time, in order to understand the anti-static ability of the light-emitting diode lamp, the manufacturer of the display panel usually conducts an electrostatic test on the light bar. During the process, LED lamps are usually damaged by static electricity, which leads to problems of product reliability and performance degradation.

Abstract

Embodiments of the present invention provide a backlight module and a display device, including: a backlight flexible printed circuit board, on which a positive electrode pad and a negative electrode pad are arranged; On one side of the circuit board, the two ends of the backlight strip are electrically connected to the positive electrode pad and the negative electrode pad of the backlight flexible printed circuit board respectively; a wire, the wire is located at least on one side of the backlight strip , and the wire is grounded. The backlight module and the display device provided by the embodiments of the present invention solve the problem of product reliability and performance degradation caused by the easy breakdown of the backlight strip during electrostatic testing.

Description

technical field [0001] Embodiments of the present invention relate to the field of display, and in particular, to a backlight module and a display device. Background technique [0002] A light bar is usually used as a light source in a backlight module of an existing display device to provide backlight for a display panel. Light-emitting diode strips have become the preferred type of strips for display panel manufacturers because of their energy-saving and environmental protection properties. [0003] The structure of the light emitting diode light bar includes electrical connection wiring between the light emitting diodes and electrical connection wiring with an external light emitting diode driving system. However, in the actual production process, the light-emitting diode will be affected by the large static electricity of the external environment. At the same time, in order to understand the anti-static ability of the light-emitting diode lamp, the manufacturer of the d...
