Patent ID: 8264429

Claim:
An organic light-emitting diode (OLED) display apparatus, comprising: a control unit to receive an image signal and to generate a frame-based image data signal and a frame identification signal based at least in part on the received image signal, the frame identification signal being synchronized with the frame-based image data signal, and identifying a starting point of each frame included in the frame-based image data signal; a driving voltage supply unit to generate a first voltage and a second voltage for driving a display unit, the driving voltage supply unit to supply the second voltage to the display unit; and a switching unit to receive the first voltage and the frame identification signal, wherein the switching unit does not supply the first voltage for driving the display unit to any pixel in the display unit during a starting point of a frame included in the frame-based image data, and supplies the first voltage for driving the display unit to a driving thin film transistor which is connected to an OLED in each pixel of the display unit when the frame identification signal indicates that the frame-based image data signal is not at a starting point of a frame.
