We introduce a viewing angle switchable backlight module, which consists of a hybrid light guide plate and dual-light sources on the same layer. Comparing with the conventional backlight module, the on-axis luminance of the narrow viewing angle improved 4.9-times and the half-luminance angle decreased 11 degrees in the horizontal direction. When using the wide viewing angle mode, the on-axis luminance improved 2-times and the half-luminance angle improved 56 degrees in the horizontal direction.
