Abstract: An organic light emitting diode (OLED) display device includes a display panel including a plurality of pixels, and a panel driver configured to drive the display panel. The panel driver drives the display panel at a frame frequency corresponding to 1/N of an emission frequency such that each frame period corresponds to an N multiple of an emission period, where N is an integer greater than 1. The panel driver gradually decreases the frame frequency of the display panel in a case where input image data are not received and gradually increases the frame frequency of the display panel in a case where the input image data are received.

Abstract: A liquid crystal display includes a timing controller and a liquid crystal panel. The timing controller sequentially receives first through third primitive image signals and sequentially outputs first through third corrected image signals. The liquid crystal panel displays an image based on the first through third corrected image signals. The timing controller generates a first converted image signal having a first gray level based on the first primitive image signal and stores the first converted image signal. The second primitive image signal has a second gray level and the timing controller generates a second converted image signal having a third gray level higher than the second gray level when the second gray level is lower than the first gray level. The timing controller generates the third corrected image signal using the second converted image signal and the third primitive image signal.
