Circuits for controlling display apparatus
First Claim
Patent Images
1. A direct view display apparatus comprising:
- a transparent substrate;
an array of pixels formed on the substrate including, for each pixel, a MEMS-based light modulator including a first movable electrostatic actuator; and
a control matrix connected to the substrate including, for a pixel, a write-enabling interconnect for enabling the pixel to respond to a data voltage and a data voltage interconnect for applying the data voltage to a data switch, thereby controlling the state of the light modulator of the pixel; 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.
