Abstract
Disclosed herein is to a display device with high resolution of display image and low current consumption. In the display device of the disclosure, the activation width of a modulation signal that causes a current to flow in a light emitting element of a display panel, reflects an activation width of a micro response signal that can be divided into a short unit time. Accordingly, the light emitting element that emits light with a brightness corresponding to the activation width of the modulation signal, can implement a high-resolution display image. The micro modulation part that includes a high frequency clock generating unit and a micro modulation unit, is disabled in a subframe in which the micro response signal is inactivated. Therefore, according to the display device of the disclosure, current consumption can be reduced with maintaining a high resolution of a display image.
