Abstract

The invention provides a backlight module which comprises a light source, a light guide plate and a reflector plate. The light source is located on the side face of the light guide plate. The bottom face of the light guide plate is provided with a plurality of lattice points arranged at intervals. The reflector plate is attached to the bottom face of the light guide plate and covers the multiple lattice points. The reflector plate is a mirror reflector plate with a mirror reflection function. The backlight module is good in light emitting effect, the thickness of the module can be reduced, and ultrathin complete machine design can be achieved.

Description

technical field [0001] The invention relates to the lighting field, in particular to a backlight module. Background technique [0002] Backlight modules are divided into side-type backlight modules and direct-type backlight modules according to the incident position of the light source. see figure 1 , which is a schematic structural diagram of an edge-lit backlight module in the prior art. The side-type backlight module includes a light source 101, a reflector 102 positioned at the periphery of the light source 101, a reflector 103, a light guide plate 104 located above the reflector 103, a diffuser plate 105 located above the light guide plate 104, and a diffuser plate 105 located above the diffuser plate 105. The prism sheet 106. In the side-lit backlight module, generally, the light guide plate 104 and the reflection sheet 103 are separately assembled in the backplane cavity of the backlight module. Existing backlight modules generally require a backplane or a structu...
