Lcd TV Monitors
LCD, or Liquid Crystal Display, technology has advanced rapidly since
its commercial inception over a decade ago for use in laptop
computers. Technical achievement has resulted in brighter displays,
higher resolutions, reduced response times, and cheaper
manufacturing processes.

It has also allowed manufacturers to
greatly increase screen size. Whereas most introductory LCD screens
only offer 12 to 14-inches of viewable area, the newest LCD monitors
now are available at over 23 inches, with LCD TVs going even further
- up to 42-inches.
So, how do LCD monitors work? Liquid crystal
displays work by trapping a liquid crystal solution between two
panes of polarized glass. The liquid crystals can be manipulated
through an applied electric voltage so that light is allowed to pass
or is blocked.
By carefully controlling where and what wavelength
(colour) of light is allowed to pass, the LCD monitor is able to
display images. A backlight provides the LCD monitors brightness,
and generally has a lifespan of approximately 60,000 to 80,000 hours
- about 20 - 25 years of daily 8-hour usage. Over the years, many
enhancements have been made to LCD technology to help improve
resolution, image sharpness and response time. One of the latest
such advancements is TFT, or thin film transistors.
TFT-LCDs make
use of a very thin transistor that is applied to the glass during
the manufacturing process.. The TFT further acts as a switch,
allowing control of light at the pixel-level, greatly enhancing
resolution and image sharpness. This has been particularly important
for improving LCDs ability to display small-sized fonts.
Other
advances have allowed LCDs to greatly reduce liquid crystal cell
response times. Response time is basically the amount of time it
takes for a pixel to 'change colours'. In reality, response time is
the amount of time it takes a liquid crystal cell to go from being
active to inactive.
Another key advancement
for LCD monitors has been the improvement of contrast ratio. This
has allowed LCD monitors to greatly improve colour reproduction, and
now allows improved gaming and movie viewing. Many manufacturers are
now also adding a specially designed low reflective coating that
helps reduce glare, increase contrast, allows brilliant colour
display.
