PIXEL AND ORGANIC LIGHT EMITTING DISPLAY USING THE SAME

摘要

A pixel for an organic light emitting diode (OLED) display is disclosed. One inventive aspect includes an organic light emitting diode, a first transistor, a first capacitor, a second transistor and a second capacitor. The first transistor is configured to control an amount of current flowing from a first power source to a second power source via the organic light emitting diode in response to a voltage of a first node. The first capacitor is connected to a data line and has a first terminal. The second transistor is connected to a second terminal of the first capacitor and a second node and is configured to be turned on when a scan signal is supplied to a scan line. The second capacitor is connected to the second and first nodes.

主权项

1. A pixel for an organic light emitting display, the pixel comprising:
an organic light emitting diode; a first transistor configured to control an amount of current flowing from a first power source to a second power source via the organic light emitting diode in response to a voltage at a first node; a second transistor electrically connected to the first node and a data line, the second transistor configured to be turned on and compensate a threshold voltage of the first transistor when a scan signal is supplied to a scan line; a first capacitor having a first terminal connected to the data line and a second terminal connected to the second transistor; and a second capacitor connected to the first node and to the second transistor at a second node.
