Abstract

A display device which is immune to a build-up of static electricity includes a display module and an anti-static layer. The anti-static layer is formed on a side surface of the display module. The anti-static layer includes an insulating layer on the side surface and a conductive layer stacked on the insulating layer. The conductive layer is electrically coupled to a conductive component of the display device.

Claims

1. A display device comprising:

a backlight module;

a display module stacked on the backlight module, the display module and the backlight module cooperatively defining at least one side surface; and

an anti-static layer on the at least one side surface;

an outer frame receiving the display module and the backlight module;

wherein the anti-static layer comprises an insulating layer on the at least one side surface and a conductive layer stacked on the insulating layer;

the conductive layer is electrically coupled to a conductive component of the display device;

wherein the insulating layer is configured to accumulate electrostatic charges, and the anti-static layer is configured to conduct the electrostatic charges from the insulating layer to the conductive component;

wherein the backlight module comprises a back plate made of an electrically conductive material;

the conductive layer extends to be electrically coupled to the back plate;

wherein the back plate comprises a bottom wall and at least one side wall substantially perpendicularly extending from the bottom wall;

the display module and the at least one side wall are coupled to define the at least one side surface;

wherein a gap is formed between the back plate and the outer frame;

the anti-static layer is in the gap;

the insulating layer is in direct contact with the at least one side surface, and the conductive layer is in direct contact with a surface of the insulating layer away from the at least one side surface.
