Abstract

The invention discloses a backlight device, which comprises: a reflective sheet, a plastic frame in contact with the reflective sheet, and a light guide plate accommodated in the plastic frame, wherein the plastic frame and the reflective The side in contact with the sheet is the first side of the plastic frame, and the side of the plastic frame facing away from the reflective sheet is the second side of the plastic frame; the plastic frame includes at least one groove for fixing the light-emitting element, The plastic frame also includes a heat dissipation channel, the heat dissipation channel is arranged in at least one of the first surface and the second surface of the plastic frame, and the heat dissipation channel is located at a peripheral position of the groove. The invention passes through the heat dissipation channel of the plastic frame in the plastic frame to form air convection in the heat dissipation channel, which speeds up the heat energy exchange and improves the heat dissipation efficiency. The heat dissipation channel and the plastic frame are integrally formed without affecting the thickness of the backlight device. Advantages of low cost and easy thinning of the backlight device.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight device for a display. Background technique [0002] The backlight module is located under the liquid crystal display panel. The liquid crystal display panel is a passive light-emitting element. It does not emit light itself, but the light source provided by the light source located in the backlight module below it. The backlight module and the liquid crystal display panel are combined together A liquid crystal display module is formed, and the luminous effect of the backlight module will directly affect the display effect of the liquid crystal display module. [0003] Since there are multiple light sources in the backlight module, heat radiation will be generated when the light sources emit light. In the prior art, heat sinks are usually used to dissipate heat from the light sources in the backlight module. Referring to Fig. 1 (a), it is a schematic diagram of a backlight module ...
