Abstract
The disclosure provides a light guide plate, a backlight unit, a display device and a display control system. The light guide plate has a first operation state and a second operation state. In the first operation state, an upper surface of the light guide plate is a surface where light comes out, and in the second operation state, the upper surface of the light guide plate includes a light exiting region and a non-light exiting region. In the technical solution of the present disclosure, when the display device performs a regional displaying, the light guide plate operates in the second operation state, here the upper surface of the light guide plate includes the light exiting region and the non-light exiting region; light emitted by a light source finally comes out from the light exiting region of the light guide plate after reflections inside the light guide plate.
