DIRECT-VIEW MEMS DISPLAY DEVICES AND METHODS FOR GENERATING IMAGES THEREON
First Claim
1. An electromechanical device, comprising:
- an array of light blocking elements, each respective light blocking element movable between at least two positions;
at least two light sources, a first light source generating light of a first color, and a second light source generating light of a second different color; and
a controller for;
moving each respective light blocking element between the at least two positions; and
controlling the light sources to generate light to pass towards the array of light blocking elements, with the light sources generating at least the first color and the second color at the same time to form an 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.
