Abstract

The invention discloses a backlight module which comprises a light box, a transparent baseplate and a plurality of luminescence units, wherein the light box is provided with an opening; the transparent baseplate is arranged in the light box; and the luminescence units are arranged on the transparent baseplate and positioned between the transparent baseplate and the bottom surface of the light box. Light rays emitted by the luminescence units can pass through the transparent baseplate and come out from the opening; thus, the heat generated by the luminescence units can be effectively and directly transferred to the exterior of the light box.

Description

technical field

[0001] The invention relates to a backlight module, and in particular to a backlight module with high heat dissipation efficiency. Background technique

[0002] In general liquid crystal displays, since the liquid crystal display panel (Liquid crystal display panel) does not have the function of actively emitting light, a backlight module must be arranged under the liquid crystal display panel to provide a side light source, so that the liquid crystal display panel can achieve the display effect. Purpose.

[0003] figure 1 It is a schematic cross-sectional view of an existing backlight module. Please refer to figure 1 , the existing backlight module 100 includes a light box 102 , a circuit board 104 , a plurality of LEDs 106 and a diffusion film 108 . Wherein, both the circuit board 104 and the LED 106 are disposed in the light box 102 , and the LED 106 is disposed on the circuit board 104 . In addition, the diffusion film 108 is disposed above the light...
