Circuits for controlling display apparatus
First Claim
Patent Images
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; and
applying 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.
