High-precision, fast current source for large-area current-programmed a-Si flat panels

Although current-programmed pixel circuits lead to a highly stable amorphous silicon (a-Si) active matrix backplane, they are prone to a long settling time due to the large parasitic capacitance coupled with the low mobility of a-Si thin film transistors (TFTs). This paper presents a fast-current source that can significantly improve the settling time of the a-Si active matrix. Also, to reduce the effect of mismatches a differential offset cancellation technique is introduced
