Abstract
An organic light-emitting diode (OLED) display apparatus, including 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, a driving voltage supply unit to generate a first voltage for a switching unit and a second voltage for a display unit, and a switching unit to receive the first voltage and the frame identification signal and to supply the first voltage for the display unit based at least in part on the frame identification signal.
Claims11
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.
A method of driving an organic light-emitting diode (OLED) display apparatus, the method comprising:
- generating a frame-based image data signal and a frame identification signal based at least in part on an image input signal, the frame identification signal identifying a starting point of each frame included in the frame-based image data signal;
- providing the frame-based image data signal to a display unit;
- generating a first voltage and a second voltage for driving the display unit, supplying the second voltage to the display unit;
- and
- alternating a supply of the first voltage to the display unit in response to the frame identification signal such that the first voltage is not supplied to the display unit during a starting point of a frame included in the frame-based image data, and is supplied 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.
