Abstract
A display device includes a display panel on which a plurality of pixels connected to data lines, reference lines, and gate lines are arranged, each pixel having an organic light emitting diode (OLED) and a driving thin film transistor (TFT); a data drive circuit to supply a data voltage to the data lines and a reference voltage to the reference lines; a gate drive circuit to generate a scan signal and a sensing signal and to supply the scan signal and the sensing signal to the gate lines, the scan signal being synchronized with the data voltage and the sensing signal being synchronized with the reference voltage; and a timing controller to divide one frame into a programming time, an emission time, and a non-emission time, and to control an emission duty by variably controlling the programming time based on an analysis of input image data.
