DISPLAY PANEL AND ORGANIC LIGHT-EMITTING DIODE (OLED) DISPLAY INCLUDING THE SAME
First Claim
1. A display panel, comprising:
- an active pixel including;
i) a driving circuit configured to generate a driving current based on a data signal and ii) an emission circuit configured to emit light based on the driving current; and
a repair pixel comprising;
a repair driving circuit configured to provide a repair driving current to the emission circuit instead of the driving current of the driving circuit when the driving circuit is disconnected from the emission circuit; and
an aging switch electrically connected to a power supply that is configured to generate an aging voltage, wherein the aging switch is configured to;
i) apply the aging voltage to the repair driving circuit during an aging operation for the active pixel and the repair pixel and ii) electrically disconnect the repair driving circuit from the power supply after the aging operation is performed.

Abstract
A display panel and organic light-emitting diode (OLED) display including the same are disclosed. In one aspect, the display panel includes an active pixel including a driving circuit configured to generate a driving current based on a data signal and an emission circuit configured to emit light based on the driving current. The display panel also includes a repair pixel including a repair driving circuit configured to provide a repair driving current to the emission circuit instead of the driving current of the driving circuit when the driving circuit is disconnected from the emission circuit. The repair pixel further includes an aging switch configured to apply an aging voltage to the repair driving circuit during an aging operation and electrically disconnect the repair driving circuit from a power supply after the aging operation is performed.
