Abstract: The organic light emitting display device is driven to be divided into a refresh frame when the data voltage is programmed in the pixel and a reset frame when the anode electrode of the organic light emitting diode is reset, and the data voltage is maintained to a first level during the reset frame. Accordingly, a separate stage for applying an on bias stress is not provided so that the bezel may be reduced.

Abstract: The display device includes a pixel circuit, wherein the pixel circuit includes: a light-emitting element configured to emit light based on a driving current; a driving transistor configured to control the driving current, and including a gate electrode, a source electrode, and a drain electrode, wherein a data voltage is applied to the source electrode; a storage capacitor connected to and disposed between the gate electrode of the driving transistor and a power voltage; and a reset transistor configured to apply an initialization voltage to an anode electrode of the light-emitting element in response to a scan signal, wherein when the display device operates in a Variable Refresh Rate mode for a refresh frame, an operating frequency of the scan signal varies for an anode reset frame of the refresh frame. Thus, response and image quality characteristics at a low gray level are simultaneously improved.
