Abstract
The invention relates to methods and apparatus for forming images on a display utilizing a control matrix to control the movement of MEMs-based light modulators.
Claims20
A display apparatus comprising:
- a substrate;
- an array of pixels formed on the substrate including, for each pixel, a light modulator including a first movable electrostatic actuator;
- and
- a voltage regulator that limits variation in a voltage across the first movable electrostatic actuator, wherein the variation in the voltage is caused by a movement of at least a portion of the first movable electrostatic actuator.
1 more element
A display apparatus comprising:
- an array of pixels including for each pixel, a light modulator;
- and
- active circuitry formed on a substrate for addressing the light modulators of the array, wherein for each pixel, the active circuitry includes a CMOS circuit comprising a flip-flop for controlling application of an actuation voltage to the light modulator.
