Abstract
An organic light-emitting diode (OLED) display panel is disclosed. In one aspect, the OLED display panel includes a substrate including a display region and a peripheral region surrounding the display region. The panel further includes a plurality of OLEDs formed in the display region, a plurality of pixel circuits formed in the display region, and a pixel repair circuit formed in the peripheral region. When one of the pixel circuits is a dead pixel circuit, the dead pixel circuit is disconnected from a corresponding dead pixel OLED and the dead pixel OLED is connected to the pixel repair circuit via a corresponding repair line. The pixel repair circuit is configured to provide the dead pixel OLED with a grayscale repair current for representing a grayscale of the image and a compensation repair current for compensating a line load of the repair line.
