Abstract: An organic light emitting display device and a driving method thereof are disclosed. The display device has sub-pixels of multiple colors. In one aspect, the organic light emitting display device detects sub-pixels which are positioned at the edges of the panel. Data for the sub-pixels on the edges are reduced so that colors on the edges are less observable.

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.
