Virtual Retinal Display Seminar Report 2004 Abstract The Virtual Retinal Display (VRD) is a personal display device under development at the University of Washington ’s Human Interface Technology Laboratory in Seattle‚ Washington USA. The VRD scans light directly onto the viewer ’s retina. The viewer perceives a wide field of view image. Because the VRD scans light directly on the retina‚ the VRD is not a screen based technology. The VRD was invented at the University of Washington in the

Liquid crystal display Reflective twisted nematic liquid crystal display. 1. Polarizing filter film with a vertical axis to polarize light as it enters. 2. Glass substrate with ITO electrodes. The shapes of these electrodes will determine the shapes that will appear when the LCD is turned ON. Vertical ridges etched on the surface are smooth. 3. Twisted nematic liquid crystal. 4. Glass substrate with common electrode film (ITO) with horizontal ridges to line up with the horizontal

A computer monitor‚ or Visual Display Unit (VDU)‚ is an output device that provides an interface for the user without leaving a permanent image. The monitor is compromised of a display device‚ the ability produce an image from the video signal sent by the source‚ and usually an enclosure. This signal contains a display adapter to generate video in a format compatible with the monitor. Usually‚ the signal is sent through a Visual Graphics Array (VGA)‚ Digital Visual Interface (DVI)‚ or High-Definition

Liquid Crystal Display A liquid crystal display (LCD) is a flat panel display‚ electronic visual display‚ or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images which can be displayed or hidden‚ such as preset words‚ digits‚ and 7-segment displays as in a digital clock. They use the same basic technology‚ except that arbitrary

Information Appliances E-Books and the Future of Reading M any of us who work in both the research and the design communities try to assess future directions for technology as part of our day-to-day occupation (or perhaps preoccupation). With the new millennium here it seems particularly appropriate to take a moment to consider where we’ve been and to speculate on what lies ahead. One key area of potential innovation is information appliances. My own interest‚ previously at Xerox
