Abstract: According to example embodiments, a transistor includes a gate, a channel layer that is separate from the gate, a gate insulating layer between the gate and the channel layer, and a source electrode and a drain electrode respectively contacting a first region and a second region of the channel layer. The gate insulating layer includes an impurity metal containing region that includes an impurity metal and contacts the channel layer. The gate insulating layer includes an impurity metal non-containing region contacting the gate that is not doped with the impurity metal.

Abstract: Provided are pixel circuits using organic light emitting diodes (OLEDs) and a driving method thereof, and an organic light emitting display including the pixel circuits. The OLED is driven to emit light by a drive transistor generating a drive current compensated with respect to a threshold voltage difference and mobility deviation. The drive transistor may receive reference voltage and data signals in response to separate scan signals supplied to the pixel circuits via different scan lines. As a result, a threshold voltage compensation time, which may include the time during which a reference voltage is supplied to the drive transistor in response to a particular scan signal, may be set long enough regardless of a time during which the data signal is supplied to the pixel circuits located in respective rows of the organic light emitting display in response to a separate scan signal.
