Abstract
An Organic Light Emitting Diode pixel compensation circuit is disclosed. The circuit includes first through fifth transistors, and a storage capacitor. The first transistor is coupled to a first scan signal, a power supply voltage, and a first electrode of the storage capacitor. In addition, the second transistor is coupled to the first scan signal, a data signal, and the third transistor. The third transistor is coupled to the power supply voltage, and the fifth transistor. Furthermore, the fourth transistor is coupled to a second scan signal, the third transistor, and the storage capacitor, and fifth transistor is coupled to a light emitting signal, and the OLED. In addition, the storage capacitor is coupled to the fifth transistor, and a low-level signal and emits light based on a drive current generated by the third transistor.
