Abstract

A direct-view display comprises a transparent substrate and an array of MEMS light modulators formed on the transparent substrate, wherein each of the light modulators can be driven into at least two states. A control matrix is formed on the transparent substrate for transmitting data and actuation voltages to the array. A controller controls the states of each of the light modulators in the array, The controller obtains a plurality of subframe data sets from a memory, wherein the plurality of sub-frame data sets correspond to an image frame, each sub-frame data set is associated with a coded weight, and each sub-frame data set indicates desired states of light modulators in multiple rows and multiple columns of the array. The controller outputs the plurality of sub-frame data sets according to an output sequence, stored at least partially in memory, to drive light modulators into the states indicated in the sub-frame data sets; and controls illumination of each of the respective sub-frame data sets of the plurality of sub-frame data sets based on the coded weight associated with the respective sub-frame data set.
