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.
