Title: DISPLAY DEVICE AND CONTROL METHOD THEREFOR
Abstract:
A display device and a control method therefor. The display device comprises a backlight source (11, 12), a liquid crystal lens layer (13) of multiple lens units arranged in a matrix, and a lens controller (31). The backlight source (11, 12) comprises three different colors of light sources. Each color of light source is circularly turned on and off. Only one color of light source is turned on at the same moment. The lens controller (31) is configured to control the matching degree between the enabling time of each lens unit and the on time of the light sources so as to select the amount of light passing through the enabled lens unit, and is further configured to enable a light exit direction of the multiple lens units to converge in an imaging area in front of a display device for imaging display.
