    Abstract: A display device includes a display panel, a source driving part, a gate driving part, a readout part and a pulse generating part. The display panel includes an array substrate on which a source line and a gate line are formed, and an opposite substrate on which a common electrode is formed. The readout part is electrically connected with at least one of the lines of the array substrate and the common electrode of the opposite substrate, and reads out a detection signal during an elimination period of a frame period. The pulse generating part outputs a control pulse for driving the readout part during the elimination period. Accordingly, a detection signal is read out through lines or a common electrode that are/is formed for displaying an image, so that an aperture ratio may be increased, and a manufacturing process thereof may be simplified.

    Abstract: A display device includes a display panel and a timing controller. The display panel includes a plurality of pixels, and the timing controller determines a driving method that includes a first sub-frame arrangement method and a second sub-frame arrangement method. An arrangement of weight values of a plurality of sub-frames of the second sub-frame arrangement method is given in an opposite order from an arrangement of weight values of a plurality of sub-frames of the first sub-frame arrangement method. The timing controller applies the first sub-frame arrangement method to a first pixel among the pixels, and applies the second sub-frame arrangement method to a second pixel that is disposed next to the first pixel.
