Embodiment 1
[0033] Such as figure 1 As shown, the backlight module 1 of the present invention includes a backplane 11 , a light guide plate 12 , an optical film 13 a , a transparent film 14 , a reflection sheet 15 and a light source 16 .
[0034] The back plate 11 has a through hole 110 for providing a light-transmitting channel for the camera. The entire backboard 11 includes a bottom board 111 and side boards 112 vertically connected to sides of the bottom board 111 . In this embodiment, the back plate 11 is formed integrally with iron, aluminum or other metals or alloys, and the bottom plate 111 and the side plates 112 form a cavity.
[0035] The light guide plate 12 is disposed in the cavity surrounded by the back plate 11 , specifically, the light guide plate 12 is disposed above the bottom plate 111 in parallel. Wherein the light guide plate 12 has a light incident surface 121 and a light exit surface 122, the side of the light guide plate 12 facing away from the light exit surfac...
