Compare LCD vs DLP TVsWritten by bradley james
What are differences between DLP and LCD TVs, and which is better choice for you?
LCD vs. Plasma to LCD vs. DLP
Two new technologies in world of TV, DLP and LCD, are now in a tight competition. Not long ago, everyone was talking about Plasma vs. LCD - which one would win? It became clear to most that Plasma, with its short lifespan of just 3-4 years, was simply not best choice. In fact, LCD screen has several benefits over plasma. For instance, LCD screens run much cooler than average plasma TV, and thus require less power to operate. Plasma TVs run so hot, in fact, that they require a fan to cool them down – which can be noisy. In addition, plasma screens have a tendency to degrade over time, slowly becoming dimmer. LCD screens, on other hand, run relatively cool, and do not degrade over time. Some Plasma owners, who have used their TVs for a few years now, have already witnessed dimming of their screens. Also, LCD screens tend to have overall better picture quality, and are typically 10 to 15 percent lighter than plasma. Now choice is mainly between LCD vs. DLP - two distinct technologies that offer slight differences in display, price, and performance. If you are looking to buy a new flatscreen TV this year, you are probably wondering which one is right for you.
What are DLP, LCD TV Screens?
DLP stands for Digital Light Processing, while LCD stands for Liquid Crystal Display. DLP technology, developed by Texas Instruments, uses a DMD, or Digital Micromirror Device, contructed of 1.3 million microscopic mirrors. Each of these mirrors is essentially a single pixel. When a digital signal enters DLP system, each mirror is either activated or not, resulting in tapestry of mirrors tilting either towards DLP light source or away. This process produces different levels of light and dark reflected by each individual mirror. The colors are produced when DLP light sources run through a red, green, and blue color filter on a moving wheel. Depending on lightness/ darkness of each mirror, colors come in an enormous amount of shades, producing vivid color images.
