Abstract

A display device includes a scan driver transmitting a plurality of scan signals to a plurality of scan lines, a data driver transmitting a plurality of data signals to a plurality of data lines, a display unit including a plurality of pixels connected to corresponding scan lines and corresponding data lines, and respectively receiving the corresponding data signal when the plurality of pixels are selected with the corresponding scan signal, and a timing controller controlling the scan driver and the data driver, dividing one frame period into a first viewpoint image display period, a second viewpoint image display period, and a black image display period, and generating image data signals corresponding to the first viewpoint image display period, the second viewpoint image display period, and the black image display period, and supplying the respective image data signals to the data driver, wherein the black image display period is shorter than the first viewpoint image display period and the second viewpoint image display period, and the image data signal corresponding to the black image display period is a black image data signal controlling the plurality of pixels not to emit light.

Claims27

Dependent claims

A display device comprising:

a scan driver for transmitting a plurality of scan signals to a plurality of scan lines;
a data driver for transmitting a plurality of data signals to a plurality of data lines;
a display unit including a plurality of pixels connected to corresponding scan lines among the plurality of scan lines and corresponding data lines among the plurality of data lines, and respectively for receiving corresponding data signals among the plurality of data signals when the plurality of pixels are selected with corresponding scan signals among the plurality of scan signals;
and
a timing controller for
controlling the scan driver and the data driver,
dividing one frame period into a first viewpoint image display period comprising at least two first sub-frames having different emitting times, a second viewpoint image display period comprising at least two second sub-frames having different emitting times, and a black image display period comprising at least one black sub-frame,
generating first viewpoint image data signals corresponding to the first viewpoint image display period, second viewpoint image data signals corresponding to the second viewpoint image display period, and a black image data signal corresponding to the black image display period, and
supplying the first viewpoint image data signals, the second viewpoint image data signals, and the black image data signal to the data driver,
wherein the black image display period is shorter than the first viewpoint image display period and the second viewpoint image display period, and a black data signal of the plurality of data signals corresponds to the black image data signal and causes the plurality of pixels to not emit light.
