Abstract
A light guide assembly for a backlight module is disclosed, comprising a metal element and a light guide element which are integrated together. At least a portion of at least a side surface of the light guide element is used to receive light emitted from a light source to generate backlight, and the metal element surrounds a side surface of the light guide element that is not used to receive light from the light source. In this way, the backlight module can omit the structures such as rubber frame, backplate, and the like, while the overall mechanical strength of the backlight module can be ensured, the thickness of the backlight module can be decreased to meet the requirement on thinning of the display device, and the production and maintenance costs can be reduced.
