PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pixel which displays an image with uniform luminance and to provide an organic light emitting display device using the same.

SOLUTION: The pixel includes an organic light emitting diode OLED; a second transistor M2 coupled between a first power source ELVDD and the organic light emitting diode for controlling a current supplied from the first power source to the organic light emitting diode; a third transistor M3 coupled between a first electrode of the second transistor and the first power source and configured to be turned off when a light emission control signal is supplied to a light emission control line; a first transistor M1 coupled between a gate electrode of the second transistor and a data line Dm and configured to be turned on when a scan signal is supplied to a scan line Sn; a first capacitor C1 coupled between the gate electrode and the first electrode of the second transistor; and a second capacitor C2 coupled between the first electrode of the second transistor and the first power source.
