ORGANIC LIGHT-EMITTING DISPLAY AND DRIVING METHOD THEREOF
Abstract:
An organic light-emitting display includes a driving transistor that drives an organic light-emitting diode, a first transistor connected between a data line supplying a data voltage and a gate electrode of the driving transistor, a second transistor connected between a reference voltage input line and a source electrode of the driving transistor, and a third transistor that directly charges the gate electrode of the driving transistor with a reference voltage supplied from the reference voltage input line, in response to a black data control signal, wherein the third transistor directly receives the reference voltage by being turned on for a certain period of time after the gate electrode of the driving transistor is programmed with the data voltage in one frame before receiving a data voltage in the next frame.
