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.
