ORGANIC LIGHT EMITTING DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

The present invention relates to an organic light emitting display device so as to reduce charge and discharge power consumption. According to an embodiment of the present invention, the organic light emitting display device comprises: a data voltage control unit calculating power consumption by using input image data, and outputting a voltage control signal in response to the calculated power consumption; a data voltage generation unit controlling at least one from a first voltage and a second voltage to be used to generate a data signal in response to the voltage control signal, and outputting the controlled voltage; a data drive unit generating the data signal to be outputted by using the input image data, and the first and the second voltage; and a plurality of pixels whose light is emitted or not emitted in response to the data signal.
