Digital Lcd
Simply put, digital LCD projectors are the next-generation projectors. They’re the immediate successor of CRT projectors, a type that is slowly being removed from the market these days. LCD pertains to the liquid crystal display technology also used in laptops and plasma TV’s. And when it comes to this technology, LCD’s are way different from its predecessor, the CRT.
Digital LCD projectors use certain systems and chips that are not present in CRT’s. And these are the very things that make the device compact and portable. The chips used are quite small and they replace the cathode ray tube that is chiefly used by CRT’s.
But more than its size, LCD projectors became the more preferable option because it has better contrast and brightness ratio. What’s more, the entire device uses less power. It has become apparent that smaller chips are able to do the same job that bulky tubes can do.
Companies that need projectors for their business operations and presentations are better off with these devices. But what’s surprising is the fact that digital LCD projectors have penetrated homes too. These projectors work even if the room is partially lit. Therefore, you really need not create a dark room just to use it. This is why the device is quite usable inside homes.
And as far as the price is concerned, LCD projectors are surprisingly a lot more affordable. Today, it is quite possible to get these devices for $1,000 or even less. On the other hand, CRT projectors still cost around $3,000 in the market. This is why the CRT’s are in the stage of being phased out.
But then again, digital LCD projectors have limits too. For one, these devices rely on pixels. As such, viewers may see small squares making up the image, just like in mosaic arts. This may happen if the image was projected to a large size. Also, the small pixels used by these LCD projectors are at risk of burning after continued use. Therefore, you may see some black or white spots in the screen.
