Abstract

The present invention relates to a dual lighting light guide plate comprising an upper plate and a lower plate. The upper plate comprises a light incident surface, a light emitting surface, a bottom surface opposite to the light emitting surface, and a side surface. The lower plate comprises a light incident surface, a light emitting surface, a bottom surface opposite to the light emitting surface, and a side surface. The bottom surface of the lower plate is disposed adjacent to the bottom surface of the upper surface. In operation, the side surface of the upper surface can reflect an incoming light into the side surface of the lower surface and vice verse. With these structures, the uniformity output light improves. The present invention also provides a backlight module using the light guide plate.
