ABSTRACT:
A method of adjusting the voltage applied across the pixels of an OLED display to compensate for aging including measuring the accumulation of trapped positive charge to produce a signal representative of such accumulation, and responding to such signal to adjust the voltages applied across the pixels of the OLED to compensate for aging.
