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 11 , a reflector 12 , a diffuser 13 , a prism sheet 14 and a light emitting diode 15 . The frame 11 includes a rectangular bottom plate 111 and four sidewalls 113 vertically extending from the edge of the bottom plate 111 to the same side thereof. The bottom plate 111 and the four si...
