Abstract
An organic light emitting diode display device includes a display unit including pixels each configured by an organic light emitting diode, a power supply unit configured to supply power for driving the display unit, a discharge unit connected to the display unit and configured to perform a discharge operation on a display driving voltage applied to the display unit, and a discharge control unit configured to control enabling and disabling of the discharge unit based on a power state of the organic light emitting diode display device.
Claims20
An organic light emitting diode display device, comprising:
- a display including a plurality of pixels each including an organic light emitting diode;
- a power supply configured to supply a display drive voltage to the display;
- a discharge circuit connected to the display and configured to perform a discharge operation on the display drive voltage applied to the display;
- and
- a discharge control circuit configured to control the discharge circuit to be enabled or disabled based on a power state of the organic light emitting diode display device.
A method of operating an organic light emitting diode display device, the method comprising:
- turning off power of the organic light emitting diode display device to stop supplying a display drive voltage to a display of the organic light emitting diode display device;
- controlling, by a discharge control circuit included in the organic light emitting diode display device, a discharge circuit that is connected to the display of the organic light emitting diode display device to turn on;
- and
- discharging, by the discharge circuit, residual current from the display drive voltage applied to the display after the power is turned off.
