Pixel and organic light emitting display using the same

摘要

A pixel capable of displaying an image with uniform brightness. The pixel includes an organic light emitting diode (OLED), a first transistor controlling an amount of current that flows from a second node coupled to a first power supply to a second power supply via the OLED to correspond to a voltage applied to a first node, a second transistor coupled between the first node and an initializing power supply, and a third transistor turned on to supply a predetermined voltage to the second node at the moment when the second transistor is turned on.

1. A pixel, comprising:
an organic light emitting diode (OLED); a first transistor controlling an amount of current that flows from a second node coupled to a first power supply to a second power supply via the OLED in response to a voltage applied to a first node; a second transistor coupled between the first node and an initializing power supply; and a third transistor turned on to supply a predetermined voltage to the second node at the moment when the second transistor is turned on, the third transistor coupled between the second node and one of an nth(where n is a natural number) emission control line, and an (n-1 )th emission control line, and a gate of the second transistor and a gate of the third transistor are connected to an (n-1)th scan line.
