Circuits for controlling display apparatus

摘要

A display apparatus includes an array of light modulators. Each light modulator has a first actuator configured to drive the light modulator into a first state and a second actuator configured to drive the light modulator into a second state. The display apparatus also includes a control matrix including, for each light modulator in the array, a single actuation voltage interconnect. The actuation voltage interconnect is configured to apply a first drive voltage to the first actuator of the light modulator and apply a second drive voltage to the second actuator of the light modulator. In addition, the actuation voltage interconnect is configured to control application of a data voltage to a latch circuit to control the application of the first and second drive voltages to the first and second actuators.

1. A display apparatus, comprising:
an array of light modulators, each light modulator having a first actuator configured to drive the light modulator towards a first state and a second actuator configured to drive the light modulator into a second state; and a control matrix including, for each light modulator, a circuit for controlling the light modulator, the circuit including a first shutter-state inverter configured to control the first actuator of the light modulator and a second shutter-state inverter configured to control the second actuator of the light modulator, wherein an output of the first shutter-state inverter is electrically connected to only one input of the second shutter-state inverter and wherein the control matrix is configured to pre-bias a voltage at an output of the second shutter-state inverter and an input of the first shutter-state inverter.
