Abstract

A backlight module comprises a light source assembly, a light guide plate and a back plate. The light guide plate comprises a plurality of sides. At least one side serves as an incident side close to the light source assembly. The light guide plate is used for guiding a beam emitted by the light source assembly. The light guide plate is in a stepped structure, and the stepped structure is formed on at least one side, except the incident side, of the light guide plate to form accommodating space. The back plate is embedded in the light guide plate, and at least part of the back plate is accommodated in the accommodating space formed by the stepped structure.

Description

technical field [0001] The invention relates to a backlight module. Background technique [0002] Figure 5 It is a schematic diagram of an existing backlight module. Such as Figure 5 As shown, the backlight module 100 includes a light source assembly 102 , a light guide plate 104 and a back plate 106 . The light guide plate 104 is disposed adjacent to the light source unit 102 and used to guide a light beam emitted by the light source unit 102 , and a plastic frame 108 limits the light guide plate 104 and the back plate 106 . Such as Figure 5 According to the existing design, since the backplane 106 is disposed on the outermost side of the backlight module 100 , the bottom 106 a of the backplane located below the light guide plate 104 and the bottom reflector 110 will increase the overall thickness of the backlight module 100 . [0003] US Patent Publication No. 20080291356 discloses a backlight module including a light guide plate, a first frame, a plurality of films, ...
