Abstract: An organic light emitting diode display device includes a display panel including a plurality of sub-pixels, each of which includes a driving thin film transistor and a light emitting diode; and an impedance detection part connected to the plurality of sub-pixels of the display panel. The impedance detection part includes a sensing circuit part, an input control part, and an analog-to-digital converter. The input control part generates a modulated output by modulating an output of the sensing circuit part and inputs the modulated output to the analog-to-digital converter.

Abstract: A gate driver, an organic light emitting diode display device and a method of driving the same, which are capable of preventing a driving transistor from affecting a light emitting diode when power is applied and when impedance is measured, are discussed. The organic light emitting diode display device can include a driving transistor connected to one end of an organic light emitting diode to supply operating current to the organic light emitting diode, an emission switching transistor switched according to an emission control signal to control flow of current supplied from the driving transistor to the organic light emitting diode, and a timing controller configured to perform control to maintain the emission switching transistor in an off state such that the driving transistor does not affect the organic light emitting diode until an internal terminal of a pixel of a display panel is stabilized when power is applied.
