Display device with enhanced brightness and driving method thereof

Abstract

A display device that does not suffer from blurring or reduction in brightness is presented. The device includes a plurality of pixels, a scan driver, a signal controller, and a data driver. Each pixel includes a light-emitting element and a driving transistor that outputs a driving current to the light-emitting element. The scan driver supplies a scan signal to the pixels. The signal controller generates a first output image signal representing a brightness higher than a reference brightness and a second output image signal representing a brightness lower than the reference brightness. The data driver converts the first output image signal and the second output image signal into a first and second data voltages and alternately supplies the two data voltages to the pixels. This way, the same images are displayed with a first period and a second period having a different brightness levels, achieving an impulsive effect between frames.
