DIRECT-VIEW MEMS DISPLAY DEVICES AND METHODS FOR GENERATING IMAGES THEREON
First Claim
1. An electromechanical device comprising:
- an array of light blocking elements having at least two positions;
at least one light source;
a controller for controlling the position of the light blocking elements, and for controlling illumination of the at least one light source, and forobtaining from a memory a plurality of sub-frame data sets corresponding to an image frame; and
processing the sub-frame data sets according to an output sequence to drive the light blocking elements into the positions indicated in the sub-frame data sets, and illuminate the at least one light source according to the sub-frame data sets to form an image; and
a sequence parameter calculation module for determining changes to the output sequence to alter the image.

Abstract
A direct-view display includes an array of MEMS light modulators and a control matrix formed on a transparent substrate, where each light modulator can be driven into at least two states, and a controller for controlling the states of each light modulator in the array. The control matrix transmits data and actuation voltages to the array. The controller includes an input, a processor, a memory, and an output. The input receives image data encoding an image frame for display. The processor derives a plurality of sub-frame data sets from the image data, where each sub-frame data set indicates desired states of light modulators in multiple rows and multiple columns of the array. The memory stores the plurality of sub-frame data sets. The output outputs the plurality of sub-frame data sets according to an output sequence to drive light modulators into the states indicated in the sub-frame data sets.
