Abstract
An organic light emitting diode display device that implements a high quality screen having uniform brightness by supplying uniform driving voltages to pixels irrespective of an external change is provided. The organic light emitting diode display device includes: an organic light emitting diode (OLED) panel comprising a plurality of pixels formed at crossings of a plurality of gate lines and a plurality of data lines of the panel; a timing controller configured to generate a plurality of control signals for driving the OLED panel; a data driver for driving the plurality of data lines; a gate driver for driving the plurality of gate lines; and a power supply unit configured to receive an input voltage and generate a stable driving voltage for driving each unit pixel of the liquid crystal panel without being affected by an instantaneous voltage rising and falling phenomenon of the input voltage.
