ORGANIC LIGHT-EMITTING DIODE (OLED) DISPLAY PANEL AND OLED DISPLAY HAVING THE SAME

摘要

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.

主权项

1. An organic light-emitting diode (OLED) display panel, comprising:
a substrate including a display region configured to display an image and a peripheral region surrounding the display region; a plurality of OLEDs formed in the display region; a plurality of pixel circuits formed in the display region and respectively connected to the OLEDs; a pixel repair circuit formed in the peripheral region; and a plurality of repair lines that extend between the pixel repair circuit and the OLEDs, wherein, 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 a corresponding repair line, and wherein the pixel repair circuit is configured to provide the dead pixel OLED with i) a grayscale repair current for representing a grayscale of the image and ii) a compensation repair current for compensating a line load of the repair line.
