Circuits for controlling display apparatus

摘要

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.

主权项

1. A method for addressing pixels in a display wherein each pixel includes a MEMS-based light modulator, first and second actuators, and a separate dual inverter latch electrically coupling the first and second actuators for maintaining an opposite logical state on the first and second actuators comprising:
loading data into a data store coupled to the dual inverter latch, wherein loading data into the data store comprises:
applying a write-enable voltage to a row interconnect associated with a row in the display;determining the next state of at least one pixel in the row; andapplying a data voltage corresponding to the next state of the pixel to a corresponding column interconnect; updating the latch state based at least in part on the loaded data such that a full actuation voltage is only applied to one of the first and second actuators; and actuating the MEMS-based light modulator.
