Abstract
An organic light emitting diode (OLED) display device includes a display panel having a display region and a peripheral region, an OLED at the display region and including an end connected to a first voltage, a pixel circuit at the display region, a repair pixel circuit at the peripheral region, a repair line for connecting the repair pixel circuit to the OLED, and a switching circuit configured to apply a second voltage to the repair line during a power-up of the OLED display device.
Claims24
A display device comprising:
- a display panel having a display region and a peripheral region;
- a light emitting diode at the display region and comprising an end connected to a power supply for applying a first voltage;
- a pixel circuit at the display region;
- a repair pixel circuit at the peripheral region;
- a repair line for connecting the repair pixel circuit to an anode of the light emitting diode;
- and
- a switching circuit configured to apply a second voltage to the repair line during a power-up of the display device before applying the first voltage to a cathode of the light emitting diode.
