Abstract
A system and method for driving a thin film diode (TFD) inclusive AMLCD or imaging device (e.g. x-ray imager) includes providing each pixel with a pair of select lines and a single data line. Drive schemes are provided which increase the circuits tolerance for spacial and temporal variations in diode (e.g. MIM diode) characteristics, improve response time, increase the circuit's tolerance for RC delays on data lines, and reduces the potential for crosstalk or image retention. In certain embodiments, where each pixel includes a pair of select lines, and a single data line, the select voltage on the first select line alternates between V.sub.S +V.sub.offset and V.sub.S -V.sub.offset for subsequent frames, while the select voltage on the other select line alternates between -V.sub.S +V.sub.offset and -V.sub.S -V.sub.offset for subsequent frames, thereby allowing voltage at the common node to be added to the data voltage. Drive schemes herein are used in conjunction with row inversion driving of pixel arrays, and some embodiments are also compatible with column inversion, frame inversion, and/or pixel inversion.
