Claim:
1. A method of operating a pixel array having pixel circuits arranged in rows, comprising the step of repeating an operation cycle defining a frame period for the pixel circuits, including at each frame period: programming a first of the pixel circuits in a first row of the rows of pixel circuits by activating a select line a first time to select the first pixel for programming; responsive to the select line being deactivated, driving the first pixel circuit while the select line remains deactivated; and activating the select line a second time, prior to the next frame period, to cause the first pixel circuit to be turned off to relax the first pixel circuit and to simultaneously reset a second pixel circuit in an other row of the rows for a programming operation to program the second pixel circuit, wherein the select line is deactivated between the first time it is activated and the second time it is activated, and wherein a period between the second time the select line is activated and an end of the frame period is fixed.
