Two new technologies in the world of TV, DLP and LCD, are now in a stiff competition.
Some People say that there is problem of motion blur in LCD TV. It was correct before few years due to the processors in the LCD projections being slower than those in the DLP TV's. However, the sets that we are now looking at have a much faster processor in them, and therefore don't have the type of holdup or rainbow effect that the older units had. Not only that, but definitely like the picture quality is better on the LCD TV's. In fact, the LCD screen has several benefits over plasma. For instance, LCD screens run much cooler than the 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 the 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 the dimming of their screens. Also, LCD screens tend to have overall better picture quality, and are typically 10 to 15 percent lighter than plasma.
The problem with LCD TV is after given enough time, it appears that LCD panels, primarily those in the blue channel, will degrade, causing shifts in color balance and a reduction of overall contrast. The test did not include a large enough array of test units to draw any conclusions about anticipated rates of degradation under normal operating conditions.
There are several unique benefits that are derived from DLP technology. One of the most obvious is small package size, a feature most relevant in the mobile presentation market. Since the DLP light engine consists of a single chip rather than three LCD panels, DLP projectors tend to be more compact. All of the current 3-pound miniprojectors on the market are DLP's. Most LCD projectors are five pounds and up.
Another DLP advantage is that it can produce higher contrast video with deeper black levels than you normally get on an LCD projector. DLP has ardent followers in the home theater world primarily due to this key advantage.
Thus due to stiff competition both LCD and DLP manufacturing companies are trying to improve the quality and are struggling for but at present DLP is having lead in it.
