Surface conduction Electron emitter Display


The SED technology has been developing since 1987. The flat panel display technology that employs surface conduction electron emitters for every individual display pixel can be referred to as the Surface-conduction Electron-emitter Display (SED). Though the technology differs, the basic theory that the emitted electrons can excite a phosphor coating on the display panel seems to be the bottom line for both the SED display technology and the traditional ....etc

A type of flat-panel display that works by sandwiching a neon/xenon gas mixture between two sealed glass plates with parallel electrodes deposited on their surfaces. The plates are sealed so that the electrodes form right angles, creating pixels. When a voltage pulse passes between two electrodes, the gas breaks down and produces weakly ionized plasma, which emits UV radiation. The UV radiation activates color phosphors and visible light is emitted from each pixel.

Also called gas discharge display, a flat-screen technology that uses tiny ....etc

A 3D display is any display device capable of conveying three-dimensional images to the viewer. There are many types of 3D displays: stereoscopic 3D displays show a different image to each eye; autostereoscopic 3D displays do this without the need for any special glasses or other head gear; holographic 3D displays reproduce a light field which is identical to that which emanated from the original scene (for the technology, see Computer Generated Holography). In addition there are volumetric displays, where some physical mechanism is used to dis ....etc

VIRTUAL RETINAL DISPLAY

The technologies of virtual reality (VR) and augmented reality (AR) are the new paradigm for visual interaction with graphical environments. The features of VR are interactivity and immersion. To achieve these features, a visual display that is high resolution and wide field of view is necessary. For AR a visual display that allows ready viewing of the real world, with superimposition of the computer graphics is necessary. Current display technologies require compromises that prevent full implementation of VR and AR. ....etc

RT stands for cathode ray tube, the common picture tube used in TV sets for decades and still the most common display type today. Newer display types like Plasma and LCD work differently and aren't as large or heavy as the CRT, but the picture isn't necessarily any better.

CRT produces its pictures from a ray of electrons emanating from a cathode in the neck of a picture tube. The ray strikes the inner face of the picture tube, which is coated with lines of phosphor that light up when struck by the electron beam. The scan line offers resolut ....etc

INTRODUCTION
Various types of displays have become common in the every day life. The displays are used in televisions, computers etc. They also have wide use in laboratories and in medical applications. The displays are those devices by which we can view moving objects. The displays are manufactured depending upon their application.

One of the hottest markets driving physics research is the demand for a perfect visual display. People want, for example, large, thin, lightweight screens for high-definition TV and outside displays and very hi ....etc

With the imaging appliance revolution underway, the need for more advanced handheld devices that will combine the attributes of a computer, PDA, and cell phone is increasing and the flat-panel mobile display industry is searching for a display technology that will revolutionize the industry. The need for new lightweight, low-power, wide viewing angled displays has pushed the industry to revisit the current flat-panel digital display technology used for mobile applications. Struggling to meet the needs of demanding applications such as e-books, ....etc

A virtual retinal display (VRD), also known as a retinal scan display (RSD), is a new display technology that draws a raster display (like a television) directly onto the retina of the eye. The user sees what appears to be a conventional display floating in space in front of them. In the past similar systems have been made by projecting a defocused image directly in front of the user's eye on a small screen, normally in the form of large sunglasses. The user focused their eyes on the background, where the screen appeared to be floating. The d ....etc
