Description

technical field

[0001] The invention relates to a backlight module and its optical board, in particular to a backlight module for liquid crystal display and its optical board. Background technique

[0002] Since the liquid crystal itself of the liquid crystal display panel does not have light-emitting properties, it is necessary to provide a light source device, such as a backlight module, for the liquid crystal display panel in order to achieve a display effect. The function of the backlight module is to supply a surface light source with sufficient brightness and uniform distribution to the LCD panel.

[0003] See figure 1 , shows a conventional backlight module 100 , which includes a frame 101 , a reflector 102 , a diffuser 103 , a prism sheet 104 and at least one LED 105 . The frame 101 includes a bottom plate 1011 and a plurality of sidewalls 1013 vertically extending from the edge of the bottom plate 1011 to the same side thereof. The bottom plate 1011 and the plura...
