Abstract

The invention discloses a backlight module and a display device, belonging to the technical field of display. The backlight module comprises a frame body, a light bar, a conductive connecting portionand at least one optical film. The frame body forms a holding space to hold the light bar, the conductive connecting portion and the at least one optical film; the light bar comprises a flexible circuit board and a plurality of light-emitting elements electrically connected to the flexible circuit board; the flexible circuit board comprises a protective film and a grounding trace; the protective film comprises at least one hollow portion which exposes at least part of the grounding trace; the grounding trace is electrically connected with the conductive connecting portion and the frame body. The frame body obtains the ground potential of the grounding wire through the conductive connecting portion to rapidly release the static electricity to protect the structure in the backlight module from being electrostatically damaged. The connection structure is simple, and reliability is high. The frame body can protect the conductive connecting portion. When the backlight module provided by theinvention is applied to the display device, the touch failure phenomenon caused by the instability of the frame potential can be avoided.

Description

Technical field [0001] The present invention relates to the field of display technology, and more specifically, to a backlight module and a display device. Background technique [0002] In a display device provided by the prior art, a backlight module is used to provide a light source. [0003] Please refer to figure 1 , figure 1 This is a schematic structural diagram of a display device provided by the prior art. A display device provided by the prior art includes: a display panel 01 and a backlight module 02 arranged opposite to the display panel. The backlight module includes an iron frame 021, and an optical film 022 is disposed in the accommodation space formed by the iron frame 021. FPC03 is bound to display panel 01, and FPC03 is used to transmit electrical signals to the display panel. There is a ground wire on FPC03, which receives the ground signal. [0004] Touch electrodes are provided in the display panel 01 to implement the touch function. For self-capaci...
