Organic Light Emitting Display Device and Driving Method Thereof

Abstract

An organic light emitting display device and a driving method thereof are disclosed, wherein the organic light emitting display device comprises a display panel provided with pixels connected to a sensing line; and a sensing unit outputting a sensing voltage of the pixel, which is input through the sensing line, as sensing data in a first sensing mode performed during power-off and a second sensing mode performed in the middle of driving a display mode, wherein the display panel includes a first capacitor connected to the sensing line to store a sensing voltage of the first sensing mode and provide the sensing voltage to the sensing unit, and a second capacitor connected to the sensing line to store a sensing voltage of the second sensing mode and provide the sensing voltage to the sensing unit.

Dependencies are inferred from the claim text.
