Abstract:
1. A display device comprising: a plurality of pixels; a data driver connected to the plurality of pixels by a plurality of data lines and applying data signals to the plurality of pixels; a scan driver connected to the plurality of pixels by a plurality of scan lines and applying scan signals to the plurality of pixels for the data signals to be applied to the plurality of pixels; a boost driver connected to the plurality of pixels by a plurality of boost lines and applying boost signals, boosting a pixel voltage charged to the plurality of pixels by the data signals, to the plurality of pixels; and a boost voltage maintaining unit receiving i) an inversion signal inverting a polarity of the data signals and ii) the boost signals, and applying a restoring voltage, restoring a voltage in the plurality of boost lines by the scan signal, to the plurality of boost lines, the boost voltage maintaining unit comprising a transfer gate switch having at least one of a clock signal and the scan signal as the gate signal turning on the transfer gate switch, wherein the restoring voltage is selected to reduce noise on the boost signals generated due to coupling between the boost lines and at least one of the data lines or scan lines.
