1. A method for driving a display, comprising the steps of:
- (a) storing a voltage value in an analog memory associated with each pixel of a display, wherein each of the pixels has a comparator associated therewith;
(b) applying a reference voltage and the voltage values stored in the analog memory to the comparators of the pixels;
(c) comparing the voltage values with the reference voltage for determining which of the voltage values matches the reference voltage; and
(d) changing the state of the pixels whose voltage values match the reference voltage.

Abstract
A system and method are provided for driving a display. A voltage value is stored in an analog memory associated with each pixel of a display, where each of the pixels has a comparator associated with it. A reference voltage and the voltage values stored in the analog memory are applied to the comparators of the pixels. The comparators are used to compare the voltage values with the reference voltage for determining which of the voltage values matches the reference voltage. The state of the pixels whose voltage value matches the reference voltage is changed.
