摘要：
This paper deals with software compensation of threshold voltage shift (VT shift) in amorphous silicon based active matrix OLED displays by use of an external microcontroller. The use of compensating circuits can result in lower aperture ratios, increased power consumption and complex driving methods and is hence unsuitable. The algorithm for software control makes use of quick parameter extraction of device physical parameters, thereby enabling prediction of VT shift corresponding to a data stream seen by a pixel.
