Abstract: A method of writing image data to a pixel array includes decoding an address and activating, based on the decoded address, two or more row selection signals. The address may be a ternary address having at least one trit. The method further includes providing the two or more row selection signals to the pixel array to select two or more rows of the pixel array, the activation of which writes the image data to pixels in the two or more rows of the pixel array.

Abstract: An improved Liquid Crystal Display (LCD) heating system is provided. Resistor meshes, in particular VCOM resistor heating meshes, in the pixel array improve capacity of the display heater (heating system) so that the display is heated faster from low temperatures. The resistor mesh design provides much lower resistance from one point in the pixel array to an edge than pixel-to-pixel horizontal VCOM resistance, thus reducing horizontal crosstalk. Further, the approach permits the display to be active during the warm-up process.

Abstract: A video eyewear device in which parallel side-by-side video signals are driven as analog signals to the left and right displays, with timing controlled by a common sampling clock.

Advantages include, for some applications, a display operates in a bi-level mode saving power relative to operating in a grayscale mode, while also being able to offer full grayscale mode in other applications. Further, advantages of some example embodiments include an extended DC-restore mode providing a longer period of DC restore voltage.

Abstract: Capacitive touch sensors are integrated with a head-mounted display (HMD) device or other video eyewear devices to create a more reliable and more intuitive user interface. The sensors, which may be implemented as an array, control various aspects of a left and right channel multimedia presentation, such as interpupillary distance or stereoscopic convergence, brightness, volume, or power mode.

Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system that has a display computer that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display. A data link transmits data at a rate of speed of greater than 200 Mbytes per second in series for at least a portion between the display computer and the active matrix liquid crystal display. In a preferred embodiment, the display system has a randomizing device that alternates the amplifier through which an analog video signal passes.

Abstract: An AC-coupled display driver circuit includes one or more DC-restore switches that are integrated within a liquid crystal display. A liquid crystal display system includes a coupling capacitor coupled at one end to a system input video signal, the coupling capacitor providing a display input video signal having a DC level offset. A liquid crystal display device coupled to another end of the coupling capacitor receives the first display input video signal at a video input for driving the display device. A switch integrated within the display device provides DC restore to the coupling capacitor.

Abstract: A color sequential display operative in one of two alternate modes. The first mode is a color sequential mode in which primary color images are displayed in successive frames while respective background light sources are simultaneously flashed on the display. The second mode is a monochrome mode in which the luminance Y signal is displayed in successive frames along with flashes of background white light.
