An organic light emitting diode (OLED) display device for simplifying a structure of an internal compensation pixel circuit is disclosed. The OLED display device is configured in such a way that an Npixel circuit shares a transistor for initializing a storage capacitor and a gate electrode of a driving transistor that belong to an (N+1)pixel circuit to initialize an OLED element. Accordingly, a transistor for initializing an OLED element is omitted from each pixel circuit, thereby simplifying a circuit structure and reducing a circuit area.

Organic light emitting diode display device with shared transistors among pixels

An organic light emitting diode (OLED) display device for supplying a data signal to a pentile pixel array to reduce power consumption is disclosed. A plurality of the same color of sub pixels that are disposed in different pixel columns and different pixel rows in a pentile pixel array have pixel structures that are right and left inverted based on the same data line and share the same data line, and thus, a data driver supplies the same color of data signals for each data line.
