Abstract: A display device includes a signal controller and a data driver. The signal controller processes an input image signal to generate an output image signal. The signal controller processes the input image signal using a correction unit. The correction unit corrects the input image signal to a first gray scale value greater than 0 gray scale value when the gray scale value of the input image signal is 0. The output image signal is based on the corrected input image signal. The data driver converts the output image signal into a data voltage to be applied to a display panel.

Abstract: A display device includes: a display panel including pixels; a scan driver which supplies a scan signal to scan lines connected to the pixels and supplies a sensing signal to sensing lines connected to the pixels; a data driver which supplies a data signal corresponding to image data to data lines connected to the pixels; a sensing part which senses a threshold voltage of a first transistor included in each of the pixels through receiving lines connected to the pixels, and corrects the sensed threshold voltage based on a voltage drop corresponding to at least one of an internal resistance of the data lines and an internal resistance of the receiving lines; and a timing controller which generates the image data by changing input image data based on the corrected threshold voltage.

Abstract: A display device includes a display panel including unit areas. Each of the unit areas includes pixels arranged in a matrix formation; and data lines (DLs) connected to the pixels. The display device is configured to: apply data voltages of a same polarity to first DLs positioned between adjacent pixel columns; and apply DVs of different polarities to second DLs positioned at respective sides of each pixel column. Each of the pixels is connected to one of the second DLs. A connection direction between the pixels and the DLs in each of a plurality of pixel rows is changed in a determined pixel column interval. Connection directions between the pixels and the DLs are opposite each other in odd-numbered pixel rows adjacent in a column direction. Connection directions between the pixels and the DLs are opposite each other in even-numbered pixel rows adjacent in the column direction.
