Embodiment Construction

[0026] It can be seen 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 to provide a light source for a display panel. LED light strips have become the preferred light strip type for display panel manufacturers due to their energy-saving and environmental protection properties. However, in the actual production process, the LED lamp will receive a large static electricity impact from the external environment. At the same time, in order to understand the antistatic ability of the LED 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, resulting in problems of product reliability and performance degradation.

[0028] In order to solve the above problem, the embodiment of the present invention pro...

Abstract

The embodiment of the invention provides a backlight module and a display device, and the backlight module comprises a backlight flexible printed circuit board, a backlight light bar, and a wire. Thebacklight flexible printed circuit board is provided with a positive electrode bonding pad and a negative electrode bonding pad; the backlight light bar is arranged on one side of the backlight flexible printed circuit board, and the two ends of the backlight light bar are electrically connected with the positive electrode bonding pad and the negative electrode bonding pad of the backlight flexible printed circuit board respectively; and the wire is at least located on one side of the backlight light bar, and the wire is grounded. According to the backlight module and the display device provided by the embodiment of the invention, the problem that the product reliability and performance are reduced due to the fact that the backlight light bar is easily broken down in an electrostatic testis solved.

Description

technical field [0001] Embodiments of the present invention relate to the display field, 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 a backlight for a display panel. LED light strips have become the preferred light strip type for display panel manufacturers due to their energy-saving and environmental protection properties. [0003] The structure of the LED light bar includes the electrical connection wiring between the LEDs and the electrical connection wiring with the external LED driving system. However, in the actual production process, the light-emitting diodes will be greatly affected by the static electricity of the external environment. In the process, light-emitting diodes are usually damaged by static electricity. Because there is no design to improve the antistatic ability of the existing LED light strips, ...
