PIXEL AND ORGANIC LIGHT EMITTING DISPLAY DEVICE USING THE SAME

摘要

The present invention relates to a pixel for displaying a desirable brightness of image. According to an embodiment, the pixel of the present invention comprises: an organic light emitting diode; a first operating transistor for providing currents for the organic light emitting diode from a first power corresponding to a voltage applied to a second node; a second operating transistor turned on or off corresponding to data signals provided from data lines, while being accessed between the organic light emitting diode and second electrode of the first operating transistor; a third transistor turned on when projection lines are provided with projection signals, while being accessed between the data lines and gate electrode of the second operating transistor; and a correction unit for storing voltage corresponding to the threshold voltage of the first operating transistor, while being accessed to the second node.
