Abstract
The present disclosure relates to a display driver and a display device using the same. The display device according to the embodiment improves an effect of preventing leakage current of a data supply transistor by adaptively controlling and supplying, on the basis of a luminance value of an input data, a parking voltage which is applied in order to prevent the leakage current of the data supply transistor. The display driver comprises a controller which provides a clock signal swinging between a high level and a low level during a refresh frame in which a data voltage is written in a pixel, and provides a clock signal having a direct current voltage during a hold frame in which the data voltage written in the pixel is maintained; a data driver which supplies the data voltage to the pixel during the refresh frame in accordance with a data control signal of the controller; and a power supplier which supplies a parking voltage to the pixel during the hold frame.
