the digital display technology of the future
[attachment=22060]
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 appears seamless because the mirror pixels used in a DLP system have very tiny spaces. This in turn gives high perceived resolution. The DLP systems are inherently reliable. DLP is a reflective technology, because the image becomes brighter and brighter as the resolution increases. As this is a reflective technology, it is more efficient than competing systems. Hence the world will definitely move over to the new technology i.e., the digital technology and we are sure that the digital technology will have a promising future
Introduction
In this information age, we are surrounded by computers, faxes, modems, pagers, and cellular telephones. These products all rely on digital technology. More recent advances have produced digital cameras, digital camcorders, digital satellite systems (DSS), and the widely anticipated digital video disk (DVD) players, which play digital source material of unprecedented image quality. And of course, who could forget the Internet, the seemingly endless forum of digitized information. Before long, digital VCRs will make their way into the homes of millions of consumers, offering yet another digital solution.
Although many of us realize the benefits of this digital technology, the majority of video displays are still based on the old analog cathode ray tube (CRT), which recently celebrated its 100th anniversary. Why would someone want to go to all the trouble of preserving digital video and graphic data only to have it converted to analog before it is viewed? Digital Light Processing (DLP) offers a solution to this problem of unrealized image quality potential. DLP, invented by Texas Instruments, is the new digital display technology. It is the final link in the chain that makes possible a completely digital video information structure. This is especially important as TVs and PCs converge to provide central information and communication media windows.
On April 3, 1997 the Federal Communications Commission (FCC), along with the major networks, officially kicked off a plan to begin the conversion process to digital television transmission. DLP brand products will be uniquely positioned as the only all-digital High Definition Television (HDTV) projection display systems available to bring viewers the best possible image quality. With DLP, consumers can enjoy the same life-like video realism that the compact disc brought to the audio industry more than 15 years ago.
Digital Light Processing (DLP)
When we compare DLP to today’s display technologies, it’s easy to see why DLP has a promising future. Because the technology is digital, DLP is able to reproduce life-like color images with precision accuracy. Seamless picture reproduction, high brightness, inherent reliability, the ability to show PC graphics and TV video, and other DLP advantages are discussed below.
How DLP Works?
DLP display technology digitally manipulates (or processes) light to produce film-like, all-digital images. DLP integrates a projection lamp and an electronic video signal from a source such as a VCR or computer, and the processed light produces an all-digital picture.
The key to this complete digital process is the Digital Micro mirror Device (DMD), a thumbnail-size semiconductor light switch. The DMD consists of an array of thousands of microscopic-size mirrors, each mounted on a hinge structure so that it can be individually tilted back and forth. When a lamp and a projection lens are positioned in the right places in the system, DLP processes the input video signal and tilts the mirrors to generate a digital image.
