The Digital Display Technology of the Future full report - divs_sit - 10-06-2017 The Digital Display Technology of the Future [attachment=800] 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. 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 Texas Instruments 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. Reliability DLP systems have passed a series of environmental and regulatory tests to simulate thermal shock, temperature cycling, mechanical shock, vibration, moisture resistance, and acceleration conditions. Most reliability concerns are focused on the hinges that tilt the mirrors from one position to another. To test reliability, DMDs were subjected to accelerated life cycle tests simulating approximately 20 years of use. Inspection of the devices after the testing showed no broken hinges on any of the devices. Texas Instruments has completed thousands of hours of life cycle and environmental testing to conclude that the DMD and DLP systems are inherently reliable. Other Display Technologies In addition to DLP, there are three other primary display technologies: amorphous silicon (am-Si) LCD, polycrystalline silicon (poly-Si) LCD, and cathode ray tube (CRT). Summary More and more of today s information is created, edited, and transmitted in the digital domain. The majority of existing display technologies are analog and limit the full potential of digital video. At present, DLP is the only digital projection solution available to produce an entirely digital video infrastructure. As PCs and TVs converge and the digital HDTV infrastructure begins to take form, DLP offers consumers the maximum benefit of digital source material by producing life-like, digitally projected images of unprecedented picture quality. |
