Systems, methods and methods of manufacture for, among other things, a MEMS display that has a substrate with a first and a second array of apertures. The first and second arrays are, typically, formed on the substrate so that the arrays are adjacent and define a field boundary line that may extend between the two arrays and along a width of the substrate. In at least one array, the apertures that are proximate the field boundary line are placed at locations on the substrate to reduce differences in luminance between one portion of the display and another portion of the display.

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.

This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display. A pixel circuit used to control one or more display elements of a MEMS display apparatus can include a first output node coupled to a first actuator of a display element and a second output node coupled to a second actuator of the display element. The first output node can be coupled to an actuation interconnect via a first pre-charge switch connected in parallel with a first capacitor. The second output node can be connected to the actuation interconnect via a second pre-charge switch connected in parallel with a second capacitor. Energizing the first output node or the second output node can cause the display element to enter or remain in a first state or a second state, respectively.

摘要:
This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display device. The state of operation of the light modulator is controlled by the pixel circuit based on a data voltage stored in a data storage element of the pixel circuit. The pixel circuit includes a compensation capacitor, which is used to inject charge into the data storage element. In some implementations, this injection of charge boosts the voltage across the data storage capacitor thereby improving the reliability of the pixel circuit.
