Abstract: An image processing method includes: receiving an input image signal (IIS); doubling the IIS into frames; determining a TGM mode to control an order in which gamma curves (GC) are to be applied to the doubled IIS, the GCs including first and second GCs; applying the GCs to the doubled IIS based on the TGM mode to generate a doubled, TGM-processed image signal (DTIS); correcting the DTIS to generate a corrected image signal (CIS); and dither-processing the CIS to generate an output image signal. The dither-processing of the CIS includes: performing dither-processing by sequentially applying dithering patterns (DP) of a first DP set to the CIS in association with first ones of the frames with respect to the first GC, and performing the dither-processing by sequentially applying DPs of a second DP set to the CIS in association with second ones of the frames with respect to the second GC.

Abstract: A display device includes a pixel unit including first pixels connected to a data line and second pixels connected to the data line; a sensing unit overlapping the first and second pixels, the sensing unit including sensing electrodes; and a sensing controller for receiving a sensing signal from at least some of the sensing electrodes in accordance with a sensing enable signal having a sensing-on level. In a first frame period, at least two of first data voltages having different levels are applied through the data line to the first pixels and second data voltages having the same level as each other but different from the first data voltages are applied through the data line to the second pixels. In the first frame period, the sensing enable signal has a sensing-off level while the first data voltages are applied and the sensing-on level while the second data voltages are applied.
