ABSTRACT:
A backlight structure comprises a light-guide plate and a light source module. There is a light-entering surface, which is a burnished surface, on one side of the light-guide plate. Besides, there is an effective light-emitting area on the light source module, and there is a distance between the centerline of which area and that of the light-entering surface. Thereby, the luminance on the bottom-left corner of the backlight structure is made identical to the luminance on the bottom-right corner by increasing the propagation ranges of the light on the bottom-left and the bottom-right corners as a result of a burnish surface as well as of asymmetrically adapting the light source module.
