Abstract: A display device includes a display panel in which a plurality of subpixels are arranged at positions at which a plurality of data lines and a plurality of gate lines overlap with each other. A gate driving circuit drives the plurality of subpixels via the plurality of gate lines. A data driving circuit supplies a data output signal to the plurality of subpixels via the plurality of data lines, and the data output signal includes a data voltage and an offset data voltage which is generated by adding an offset to the data voltage. A timing controller controls the gate driving circuit and the data driving circuit.

Abstract: Discussed is a display device including a display panel including first and second display areas that differ in the number of sub-pixels per unit area, a data driver that generates data voltages, and supplies the data voltages to the sub-pixels in the corresponding areas, and a power supply part that generates first display area high-potential power for the first display area and second display area high-potential power for the second display area, and supplies the first and second display area high-potential powers to the corresponding display areas. Each of the sub-pixels includes a switching transistor connected to a gate line and a data line, and a pixel circuit including a driving transistor that is turned on in response to a data voltage stored in a storage capacitor, and supplies a driving current to an organic light-emitting diode positioned between a first power line and a second power line.
