Liquid crystal display (LCD) monitors can provide the consumer with impressive savings on a long-term basis, consuming at least 50% less energy than a standard cathode ray tube (CRT) monitor. This is possible because the LCD shines light through a blend of polarized glass and crystals to produce an image and the CRT does this by projecting electrons through a glass tube.
Why people prefer the LCD
LCDs that carry the Energy Star label are even more economical, and some affiliated companies provide a useful web-based calculator so that shoppers can easily determine what they might be able to save by choosing the newer type of monitor.
Some other benefits of LCD monitors that aren’t quite so obvious to the consumer at first glance include:
? a reduction in heat generation, which lowers air-conditioning costs in the summer months and conserves energy all year long,
? increased brightness and less image distortion,
? freeing up of desk space because this monitor is lighter, thinner and smaller, and
? less eye fatigue for the user because LCDs are not as intense and emit less glare, and this is combined with the ongoing display of on-or-off pixels for an overall positive effect.
The versatility of an LCD monitor
Because it is at least 80% lighter than an equivalent CRT screen, users can now have larger screens on their computers, and they are highly adjustable. In addition many LCDs come with 90-degree rotation, allowing websites to be viewed in portrait mode, and they can be mounted on an arm or the wall. Also, the available viewing area increases for the user because a CRT lacks the capability to display an image on its outermost edges, but a TFT LCD monitor has that feature.
Deciding on an LCD monitor
Today, the typical user will probably choose an LCD monitor rather than a CRT. The climate for doing is this is favorable because the production of CRTs has been noticeably reduced while the production of LCDs has increased, and the overall cost of either type is virtually the same. However, CRTs will continue to be favored by anyone with special imaging needs, including medical professionals and graphic artists, because they provide a smoother transition of color and action, along with the flexible resolution they require. Alternatively, for those who plan to visit a website in a confined space or read a document on a word processor, the LCD provides crisp text projection and high contrast while it uses less energy.
Along with all of its popular features, the LCD also has a few limitations, including what is known as “fixed resolution.” This means that the screen only displays the pixels it has in the matrix, and this can result in a blurred image, especially if the accompanying text is transmitted via fixed resolution. Potential buyers should also be aware that the upfront purchase price may be higher, and that the LCD comes with a less extensive viewing angle, lower color quality, and limited choices in screen resolution.
