摘要
A fast and accurate current programming method with a current unity-gain amplifier which provides high gain and driving capability has been designed. Experimental results show that the maximum error of the programming current in pixels is less than 0.22 least significant bit using the proposed current driving method and the lowest grey-level current, 6.7 nA, can be successfully programmed within 19 mu s. The power consumption of the proposed current driving method with a channel is 10.5 mu W. This performance is good enough to apply to a 12-inch-wide extended graphics array resolution format active matrix organic light emitting diode display with 8-bit greyscale.
