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.

Abstract: A source drive integrated circuit includes a source driving circuit, output buffers, and voltage protection circuits. The source driving circuit generates data voltages according to a source timing control signal and digital video data. The output buffers output the data voltages from the source driving circuit to output terminals. The voltage protection circuits are connected between the output buffers and the output terminals. A voltage supplied to at least one of the voltage protection circuits is different from a voltage supplied to remaining ones of the voltage protection circuits.
