Abstract

The invention discloses a three-dimensional display. The three-dimensional display comprises a time sequence controller and a pair of active glasses, wherein the time sequence controller comprises a frame counter and a line buffer connected with each other in sequence; the frames are counted by the frame counter; when the frame number reaches a set constant, white image data are written into the line buffer and output and displayed as a white picture; the pair of active glasses is provided with a photosensitive module; and left and right lens switches of the active glasses are switched while the white picture is sensed by the photosensitive module. According to the invention, by using a time sequence controller embedded with a pluggable specific picture, the white picture is automatically plugged in the display picture in left-to-right direction while a three-dimensional display mode is switched to; therefore, the white picture can be also sensed by the photosensitive module at the front ends of the active glasses to control the switches of the left and right lenses of the glasses so that the desired synchronous action is realized to save an infrared/Bluetooth signal transmitter and reduce the cost.
