Abstract:
A thin film transistor includes a substrate, a gate electrode, a buffer layer, a gate insulating layer, an active layer, an etching stop layer, a source electrode and a drain electrode. The gate electrode is formed on the substrate. The buffer layer partially covers both side portions of the gate electrode. The gate insulating layer covers the gate electrode and the buffer layer. The active layer is formed on the gate insulating layer. The etching stop layer is formed on the active layer, and has a first opening and a second opening on the active layer. The source electrode is formed on the etching stop layer, and contacts with the active layer through the first opening. The drain electrode is formed on the etching stop layer, and is contacted with the active layer through the second opening.
Abstract:
An organic light emitting display includes a plurality of pixels. Each pixel includes an organic light emitting diode, a first driver, and a second driver. The first driver supplies a predetermined current to the OLED based on a current data signal or first data signal. The second driver is coupled between the first driver and OLED, and controls the coupling between the first driver and OLED based on a second data signal.
Abstract:
A pixel includes first through sixth transistors and an organic light emitting diode. The first transistor includes a gate electrode connected to a first node, a first electrode, and a second electrode connected to a second node. The second transistor provides a data signal to the first node in response to a scan signal. The third transistor provides a first power voltage to the first transistor in response to an emission control signal. The fourth transistor provides a reference voltage to the first node in response to a voltage control signal. The fifth transistor provides the reference voltage to the first node in response to an initialization control signal. The sixth transistor provides an initialization voltage to the second node in response to the initialization control signal. The organic light emitting diode is connected between the second node and a second power voltage.
