LOCALLY REFERENCED VOLTAGE PROGRAMMED PIXEL FOR AMOLED DISPLAYS

摘要

Disclosed is a technique for providing a stable current driver for active matrix light emitting displays, in particular, active matrix organic light emitting diode (AMOLED) displays. The techniques include a driving method to generate a gate-source voltage independent of the threshold voltage of the drive thin film transistor (TFT) and OLED voltage, by using a local current reference.
