Abstract:
A display matrix is provided for forming a composite image from a series of sub-images. The display matrix includes a plurality of display elements, each display element including a pixel (16), and a display circuit (18) electrically connected to the pixel. Each display circuit includes a plurality of memory cells (20A, 20B), and a selector (20) for outputting to the pixel data from one memory cell at a time where the plurality of memory cells (20A, 20B) are non-addressably connected to the selector (20).
Abstract:
A device such as a display device (115, 505) or a spatial light modulator can store pixel data in a plurality of small circuits (761, 791, 801, 901, 905, 525) coupled to pixel mirrors (718, 521) and simultaneously drive these pixel mirrors (718, 521) a frame at a time. This device is particularly beneficial for implementing improved image quality techniques which can convert binary images to grey-scale images and/or separate red, green and blue images into color images and displaying those images using the natural process of integration which occurs when a person views images at sufficiently high rates.

[PROBLEM] To provide substantially the same voltage to a shutter electrode and a pair of control electrodes, and to prevent degradation of the mechanical shutter, during a discharge period in a movable shutter system in an image display device. [RESOLUTION MEANS] A plurality of pixels are provided each having a mechanical shutter, wherein the mechanical shutter comprises a shutter electrode and first and second control electrodes provided in a pair with respect to the shutter electrode; and the display device displays images by electrically controlling a position of the shutter electrode; wherein the display device comprises a discharge period and a display period, and in the display period, a low voltage drive voltage of VL, or a high voltage drive voltage of VH with a voltage higher than the low voltage drive voltage of VL, is supplied to the shutter electrode, the first control electrode, and the second control electrode, and |Vs - Vp1| ≤ (VH - VL)/10, and |Vs - Vp2| ≤ (VH - VL)/10, where Vs is a voltage supplied to the shutter electrode, Vp1 is a voltage supplied to the first control electrode, and Vp2 is a voltage supplied to the second control electrode.
Abstract:
A display device includes a liquid crystal display having a plurality of pixels, each pixel having a corresponding pixel electrode. Each pixel also includes a volatile memory (VM) cell and a non-volatile memory (NVM) cell. The VM cell includes a VM cell input for receiving data to be stored in the VM cell and a VM cell output for outputting data stored in the VM cell. The NVM cell includes an NVM program input operatively coupled to the VM cell output, and an NVM data output for providing data stored in the first NVM cell to the pixel electrode. The display device also includes programming logic operatively coupled to each of the plurality of pixels, wherein the programming logic is configured to substantially simultaneously program each pixel's first NVM cell with data provided by each pixel's VM cell.
