Abstract:
1. A stereoscopic image display device, comprising: a scan driver that transmits a plurality of scan signals to a plurality of scan lines; a data driver that transmits a plurality of data signals to a plurality of data lines; a light emission control driver that transmits a plurality of light emission control signals to a plurality of light emission control lines; a display including a plurality of pixels connected to a corresponding scan line of the plurality of scan lines, a corresponding data line of the plurality of data lines, and a corresponding light emission control line of the plurality of light emission control lines, the plurality of pixels having transmitted thereto a corresponding data signal when a corresponding scan signal is transmitted thereto; and a controller that controls the scan driver, the data driver, and the light emission control driver, that generates image data signals corresponding to a left-eye image display period, a right-eye image display period, a black image display period after each of the left-eye image display period and the right-eye image display period during one frame, and a shutter stabilization period during the black image display period, and that supplies the image data signals to the data driver, wherein the black image display period in which a black image according to a black data signal is displayed and the shutter stabilization period in which a left eye glass and a right eye glass of shutter spectacles are opened/closed overlap each other between the left-eye image display period and the right-eye image display period, wherein a shutter synchronization signal is to open a right eye of the shutter spectacles in the shutter stabilization period after the left-eye image display period, wherein the shutter synchronization signal is to open a left eye of the shutter spectacles in the shutter stabilization period the right-eye image display period, wherein the shutter stabilization period is between a start time and an end time of the black image display period, wherein the shutter stabilization period is less than the black image display period, wherein a duty ratio of the plurality of light emission control signals is adjusted according to a shutter reaction speed of the shutter spectacles, the controller is to generate a vertical synchronization signal and the shutter synchronization signal, the vertical synchronization signal divides each frame into equal four sub-frames of the left-eye image display period, a first black image display period, the right-eye image display period, and a second black image display period, and the shutter synchronization signal activates the shutter stabilization period, a logic level of the shutter synchronization signal to change after a start of a sub-frame of each of the first and second black image display periods but before an end of the respective black image display period.
