Abstract: A display apparatus includes a display and a controller. The display includes a plurality color sub-pixels, each including an organic light emitting diode and a driving transistor to drive the organic light emitting diode. The driving transistor drives in a saturation region for a normal mode and in a linear region for a standby mode. The controller controls a first portion of preset-color sub-pixels among the color sub-pixels to emit light and a second portion of the preset-color sub-pixels among the color sub-pixels to not emit light in the standby mode.

Abstract: A display device includes a display panel including a plurality of pixel rows, and a panel driver which drives the display panel. The panel driver determines whether input image data represents a still image. When the input image data represents the still image, the panel driver determines a flicker value of the still image, applies a compensation value corresponding to a carry shift interval to the flicker value, determines a driving frequency for the display panel based on the flicker value to which the compensation value is applied, and performs an alternate driving operation for the display panel at the driving frequency.
