    摘要： In an illustrative embodiment, an instant camera is provided which includes an imager for receiving an image of an object to be photographed. The imager outputs a signal corresponding to the received image, and a memory device stores the signal. A printer prints instant film photographs corresponding to received or stored images, and has the capability to print at least one image on a single piece of instant film. A preview unit has at least one display for displaying an image corresponding to a received or stored image. A controller, in communication with the imager, the memory device, the printer, and the preview unit, controls the transfer of the signal from the imager to the memory device, from the memory device to the printer, and from the memory device to the preview unit.

    摘要： An apparatus and method for providing a display cell structure based on the transmissive liquid crystal technology with a useful aperture ratio even as the cell size shrinks to less than 20 microns. The invention overcomes a problem of the prior art wherein the fractional area transmitting the light of the conventional designs becomes unacceptably low due to the aperture reducing opaque storage capacitor. This reduction in aperture ratio is removed in this invention by hiding the trench capacitor below the row and column x,y lines. The cell storage capacitor is formed using a vertical trench capacitor in SOI. Although useful even in standard display sizes and configurations, the invention is particularly useful for head-mounted displays and/or optical projection displays at the UXGA form factor for both monochromatic and color displays. Alternate capacitor configurations are described.

    摘要： This invention provides a circuit and method to replace the passive resistive or statically biased active load devices with dynamically biased active load devices. This allows the load devices to present an effective load which varies depending on the state of the circuit output. The effective load and the time rate of change of the effective load can be dynamically optimized to improve circuit performance with changing conditions. The effective load is varied according to the state of the circuit by the use of time-delayed negative feedback. The biasing of the load devices is also capable to control the logic swing of the circuit. A bias generating circuit employing a dynamically biased active load is described. This provides a method for a family of logic circuits, especially CML circuits, to operate at low voltage and low power at high switching speeds, having symmetrical rise and fall times and well defined logic signal swings. The output is sampled and maintained at near ideal bias voltage with a voltage follower type circuit which provides a gain of less than unity and finite delay. Particular circuit implementations using various semiconductor technologies are described and many others are possible. Although the invention may find primary use in VLSI logic circuits, especially those requiring high speed and low power, it is also shown to be useful in analog circuits. Alternate circuit configurations for dynamically biased active load devices are described.

    摘要： A method and structure is presented for a display with reduced size pixels while retaining the transmissive approach. This enables continued use the least expensive transmission optics available. In an embodiment, it employs back-end-of-the-line vertical cells built on top of the row and column x, y lines of the pixels. In a PDLC type display embodiment each vertical cell is filled with PDLC which operates in a normally black mode known as the PDLC reverse mode. When the pixel control voltage is set ON, the liquid crystal is perpendicular to the light path resulting in a light pass through providing a bright state. When the control voltage is set OFF, the liquid crystals are randomly oriented, only the scattered light goes through the cell, so the pixel is in its OFF state. PDLC used here has two advantages. Firstly, the PDLC requires no rubbing. It is difficult to rub individual cell walls. Secondly, the use of both polarizations by the PDLC increases its luminous efficiency. Various embodiments are described for implementing vertical active electrodes and common ground electrodes. Advantages are described for employing the vertical electrodes with various implementations of a hidden storage capacitor.
