[0041] Such as figure 2 As shown, according to the first embodiment of the present invention, a backlight module is provided, including:

[0042] The bottom polyester film (White polyester film) 11, also referred to as the bottom layer in the backlight module, is used to protect and support the backlight module. Generally, the bottom polyester film 11 is made of polyester material.

[0043] An adhesive layer (Adhesive layer) 12 disposed on the bottom polyester layer 11 , the adhesive layer 12 has high adhesiveness, is used for bonding the bottom polyester layer 11 and the brightness enhancement layer 13 .

[0044] A brightness enhancement layer 13 (Top coat layer) disposed on the adhesive layer 12, further, the brightness enhancement layer 13 is used to increase the brightness of the light emitted from the backlight module.

[0045] The silver anti-layer 14 arranged on the brightness enhancement layer 13, usually, the silver anti-layer 14 is made of metal, therefore, after t...

Abstract

The invention provides a backlight module and a display device. The backlight module includes a bottom polyester layer; an adhesive layer disposed over the bottom polyester layer; A brightening layerdisposed over the adhesive layer; A silver inverse layer disposed over the brightness enhancement layer; A tackifying coating disposed over the silver counter layer; A polyester layer disposed over the tackifying coating; A grounding wire arranged above the polyester layer; Wherein vias in contact with the silver counter layer are provided in the polyester layer and the tackifying coating, and theground wire is electrically connected with the silver counter layer through the vias. As that via is arrange to ground the silver reverse lay, the charge of the silver reverse layer is led out, thereby preventing the silver reverse layer from being affected by electrostatic impact on other devices, and improving the protection capability of the backlight module against electrostatic impact.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the rapid development of modern society, the competition among display device manufacturers is becoming more and more fierce. In order to make their products more competitive, they must not only improve the quality of the products, but also lower the prices of the products. [0003] Generally, a display device includes a backlight module and a display module. As the technology of the display module becomes more and more mature, there are fewer and fewer ways to reduce the cost and price of the display module. The cost price of the group, thereby reducing the cost price of the display device. [0004] Such as figure 1 As shown, the lower-cost backlight module structure in the prior art includes a polyester layer 16, an adhesion-promoting coating 15, a silver anti-layer 14, a brightness-enhancing layer 1...
