ABSTRACT:
A pixel structure for use in a display using organic light emitting diodes (O-LEDs) is described. Each pixel structure of an overall array includes an organic light emitting diode (O-LED). Additionally, the structure includes circuitry for allowing the structure to operate in three basic modes: write select mode, write deselect mode and an illuminate mode. Hence, the structure includes circuitry for causing the pixel structure to be selected such that data can be written to the pixel structure, said data representative of a programmed current level to be applied to the O-LED; circuitry for causing the pixel structure to be deselected when a pixel structure in a different row is having data written thereto; and circuitry for applying the programmed current level to the OLED, causing the O-LED to illuminate.
