Abstract: A display device comprises: a panel comprising a pixel array; a data driver for outputting video data signals to the panel; and a latch part for receiving the video data signals from the data driver and outputting the received video data signals to the pixel array. With this configuration, the number of data drive ICs of the data driver can be reduced while maintaining the panel driving frequency.
