Abstract
A system and method for driving a MIM diode inclusive AMLCD 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 MIM device 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,+V,and V,−V,for subsequent frames, while the select voltage on the other select line alternates between −V,+V,and −V,−V,for subsequent frames, thereby allowing voltage at the common node to be added to the data voltage. Accordingly, a lesser data voltage swing is required, which reduces the cost and complexity of the overall circuit.
