Efficient programming and fast calibration schemes for light-emitting displays and stable current source/sinks for the same |
摘要 |
<p>A circuit and driving technique to improve the display resolution of an AMOLED display. Sharing of switch transistors between several sub-pixels in the display leads to improved manufacturing yield by minimizing the number of transistors used. The method also allows for conventional sequential scan driving to be used. A technique to implement a stable and high impedance current sink or source onto a display substrate using a single device is also disclosed. Finally, a technique is disclosed for improving the spatial and/or temporal uniformity of a light-emitting display by providing a faster calibration of reference current sources and reducing the noise effect by improving the dynamic range, despite instability and non-uniformity of the transistor devices.</p> |
