Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 1 According to a preferred embodiment of the present invention, a schematic diagram of a surface of a light bar used for electrostatic discharge protection in a backlight module of a liquid crystal panel is shown. As mentioned above, in order to prevent high-voltage static electricity generated during manual or machine operation, it is often necessary to set up a certain static electricity discharge path to protect the backlight LED of the backlight module and the corresponding circuit board from damage. refer to figure 1 , the backlight module at least includes: a light bar 10 , a bracket 20 and a connecting piece 30 . Wherein, the bracket 20 is used for accommodating the light bar 10 when the light bar 10 is pushed in. Moreover, the light bar 10 has two surfaces, namely a first surface and a second surface, and the second surf...

Abstract

The invention discloses a backlight module of a liquid crystal display panel, which is suitable for preventing static discharge from damaging a backlight LED and a circuit board. The backlight module comprises a light bar, a bracket and a connecting member, wherein the light bar comprises a plurality of LEDs positioned on the first surface of the light bar and a grounding copper sheet positioned on the second surface of the light bar; the bracket is used for accommodating the light bar when the light bar is pushed in; one surface of the connecting member is electrically connected to the bracket and the other surface is electrically connected with the grounding copper sheet on the second surface of the light bar. By adopting the backlight module, the grounding copper sheet is laid on the back surface of the light bar of the backlight module, and the grounding copper sheet is adhered on the bracket through a conductive double sticky tape, thus static discharge protection can be better carried out. In addition, the copper sheet laid on the back surface of the light bar is relatively larger, the conducting effect between the copper sheet and the sticky tape is better, and the impedance of a static discharge protection path is lower.

Description

technical field [0001] The invention relates to a liquid crystal panel in a liquid crystal display, in particular to a backlight module capable of effectively protecting electrostatic discharge in the liquid crystal panel. Background technique [0002] At present, for any type of thin film transistor liquid crystal display (TFT-LCD), the internal backlight module often generates static electricity during the assembly process, although static electricity can be generated in various ways, for example, it may be that the operator is assembling However, what people are most concerned about is that if this high-voltage static electricity cannot be effectively released or eliminated, it will easily cause damage to the backlight LED and related circuit boards. [0003] In the prior art, a commonly used technical solution is to make an annular protective band on the circuit board so as to generate a low-impedance conduction path around the circuit board of the light bar to discharge...
