20110012883 | METHOD AND SYSTEM FOR PROGRAMMING AND DRIVING ACTIVE MATRIX LIGHT EMITTING DEVICE PIXEL - Method and system for programming and driving active matrix light emitting device pixel is provided. The pixel is a voltage programmed pixel circuit, and has a light emitting device, a driving transistor and a storage capacitor. The pixel has a programming cycle having a plurality of operating cycles, and a driving cycle. During the programming cycle, the voltage of the connection between the OLED and the driving transistor is controlled so that the desired gate-source voltage of a driving transistor is stored in a storage capacitor. | 01-20-2011 |
20110134094 | SYSTEM AND DRIVING METHOD FOR ACTIVE MATRIX LIGHT EMITTING DEVICE DISPLAY - Active matrix light emitting device display and its driving technique is provided. The pixel includes a light emitting device and a plurality of transistors. A capacitor may be used to store a voltage applied to a driving transistor so that a current through the light emitting device is independent of any shifts of the transistor and light emitting device characteristics. A bias data and a programming data are provided to the pixel circuit in accordance with a driving scheme. | 06-09-2011 |
