    Abstract: A display device includes pixels electrically connected to first scan lines, second scan lines, and emission lines, a first scan driver that applies first scan signals to the first scan lines, a second scan driver that applies second scan signals to the second scan lines, an emission control driver that applies emission signals to the emission lines, and a power supply that generates and outputs a first high voltage and a second high voltage. The second scan driver receives the first high voltage. The first scan driver and the emission control driver share the second high voltage.

    Abstract: A display device includes: a display panel including pixels connected to compensation gate lines, and a compensation gate driver which supplies compensation gate signals to the display panel. The compensation gate driver includes: a first compensation gate driver which generates the compensation gate signals based on a first-first clock signal and a second-first clock signal and a second compensation gate driver which generates the compensation gate signals based on a first-second clock signal and a second-second clock signal. The first-first clock signal and the second-first clock signal have the same waveform as the first-second clock signal and the second-second clock signal, respectively, during a scan period in which a compensation gate signal is supplied to the display panel, and have different waveforms from the first-second clock signal and the second-second clock signal, respectively, during a blank period in which the compensation gate signal is not supplied to the display panel.

    Abstract: A display device includes first and second initialization voltage sources and first and second pixel circuits. The first initialization voltage source provides a first initialization voltage. The second initialization voltage source provides a second initialization voltage less than the first initialization voltage. The first pixel circuit includes a first organic light emitting diode. The second pixel circuit includes a second organic light emitting diode with an organic material having a band gap different from a band gap of an organic material in the first organic light emitting diode. The first pixel circuit is coupled to the first initialization voltage source and the second initialization voltage source. The second pixel circuit is coupled to a single initialization voltage source.

    Abstract: A display device includes a substrate having a pixel area with at least a first rounded corner portion and first to third non-pixel areas arranged sequentially along an outer circumference of the pixel area. An internal circuit in the first non-pixel area has a first end portion adjacent to the first rounded corner portion of the pixel area. The first end portion of the internal circuit is rounded in accordance with the first rounded corner portion. A plurality of routing wires are in the third non-pixel area below the pixel area. The routing wires extending to the pixel area via the second non-pixel area and the first non-pixel area. The routing wires include at least a first routing wire connected to the pixel area passing an area of the first end portion of the internal circuit.

    Abstract: A display device includes: a substrate; scan lines extending in a first direction, and arranged along a second direction crossing the first direction on the substrate; data lines extending in the second direction, and arranged along the first direction on the substrate; a display area including pixels connected to the scan lines and the data lines; and a non-display area around the display area, and including compensation capacitors connected to some scan lines from among the scan lines. A sum of a capacitance of q odd scan lines or q even scan lines that are adjacent to each other from among the scan lines increases in the second direction, where q is a positive integer.
