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

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

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

ABSTRACT
In the present world, the display technology is usually analog. But, we present the future technology i.e., the digital technology. The analog display technologies limit the full potential of digital video. So, the digital display devices will be in the market soon. In our paper, we emphasize on Digital Light Processing (DLP). This DLP display technology manipulates the light digitally to produce all-digital images. This technology reproduces color images with precision accuracy in a seamless fashion. The picture ap ....etc

E-WASTE MANAGEMENT
SEMINAR REPORT
Submitted by
BINDU V.GOPAL
DEPARTMENT OF CIVIL ENGINEERING
COLLEGE OF ENGINEERING TRIVANDRUM


ABSTRACT


The electronic industry is the world’s largest and fastest growing manufacturing industry in the world. Discarded electronic and electrical equipment with all of their peripherals at the end of life is termed e-waste. The quantity of e-waste generated in developed countries equals 1% of total solidwaste on an average and is expected to grow to 2% by 2010 and i ....etc

ABSTRACT
With a 100-year head start over more modern screen technologies, the CRT is still a formidable technology. Itâ„¢s based on universally understood principles and employs commonly available materials. The result is cheap-to-make monitors capable of excellent performance, producing stable images in true colour at high display resolutions. But in the world of miniaturization, Cathode ray tubes (CRT) are giant dinosaurs waiting for extinction. A CRT uses a single-point hot electron source that is scanned across the sc ....etc

CRT MONITOR cathode-ray tube



Disadvantages of CRT

They have a big back and take up space on desk.
The electromagnetic fields emitted by CRT monitors constitute a health hazard to the functioning of living cells.
CRTs emit a small amount of X-ray band radiation which can result in a health hazard.
Constant refreshing of CRT monitors can result in headache.
CRTs operate at very high voltage which can overheat system or result in an implosion
Within a CRT a strong vacuum exists in it ....etc
