Species of the light guide plate, a backlight module, a display apparatus and a display control system

The present invention discloses a kind of the light guide plate, a backlight module, a display device and a display control system, to reduce power consumption when the display area of ​​the display device is performed. The light guide plate has a first operating state and a second operating state; the first operating state, the upper surface of the light guide plate exit surface; a second operating state, the upper surface of the light guide plate includes a light exit region and a non-light region. In the technical solution of the embodiments of the present invention, when the area display device, the light guide plate operate in a second operating state, when the upper surface of the light guide plate includes a light exit region and a non-light region, of light incident on the light guide plate when the display the final region is emitted from the light guide plate reflection of the light guide plate. When compared to the prior art, the display area of ​​the display device is performed, the light utilization efficiency is relatively high, and therefore, under the premise of satisfying the requirements of the display, power consumption of the light source can be reduced, i.e. to reduce power consumption when the display area of ​​the display device is performed .
