Everything About LCD Monitor

And LCD monitor or liquid crystal display is a display device that composed of monochrome pixels that are arrayed on a source of light or more commonly known as the reflector. LCD’s are most often used in electronic devices that are battery-powered because of the fact that this thin and flat display device uses relatively small amounts of electricity.

Layers of molecules compose each pixel of an LCD monitor. These molecules are fixed between layers of transparent electrodes.

Some specifications that you have to consider when analyzing an LCD monitor are the resolution, the dot pitch, response time, matrix type, viewing angle, contrast ratio, aspect ratio and the brightness.

Continuation to previous post…
3. The LCD monitor has a consistent tonal scale, an excellent text contrast and it does not normally flicker. The CRT monitor has strong bright areas that may cause other parts of the picture to dim. CRT monitors also have poor text contrast because of the limited bandwidth. CRT monitors also inherently flicker.
4. The contrast and color of the images displayed by an LCD monitor may change with respect to the viewing angle while the CRT monitor delivers consistent image.
5. On dark images, the LCD monitor displays black poorly while the CRT monitor provides good blacks given that the monitor is properly adjusted.

Here are some comparisons between the LCD and CRT monitors. Which is better? Or the proper question could be which one fits your needs?
1. The LCD monitor is compact, lightweight and consumes low amounts of power (approximately 20 Watts) while the CRT monitor is bulky, heavy and consumes high amounts of power (approximately 150 Watts).
2. The LCD monitor displays perfectly sharp images with perfect image geometry. The CRT monitor has limited sharpness in its display and may tend to blur at higher levels of brightness. The CRT monitor also has the tendency to encounter geometric distortions and this case may worsen with respect to age.

LCD is short for liquid crystal display, a type of display that is used in digital watches and many portable computers. The LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them and when an electric current passes through the liquid, it causes the crystals to align. Each crystal is like a shutter, it either allows the light to pass through or blocks the light.

The monochrome LCD images usually appear as blue or dark gray images on top of a grayish-white background while the colored LCD displays use two basic techniques for producing color: the passive matrix (which is less expensive of the two technologies) and the thin film transistor (TFT) or active-matrix.

You can save energy using a more efficient monitor…the LCD.

Choosing an ultra high efficiency LCD monitor can reduce your energy usage, even over other LCD monitors. The ultra high efficiency monitors use up to 80% less energy than an average CRT monitor.

You can actually save 520 kWh/year by switching from your old CRT to ultra high efficiency LCD monitor or the qualifying monitor. You can even save 360 kWh/year by switching from a standard LCD monitor to ultra high efficiency LCD monitor. Qualifying monitors can also eliminate about 1000 lbs. of CO2 emissions over the lifespan of the monitor

Liquid Crystal Display(LCD) is technology that uses rod-shaped molecules (liquid crystals) that flow like liquid and bend light. Unenergized, the crystals direct light through two polarizing filters, allowing a natural background color to show but when it is energized, filters redirect the light to be absorbed in one of the polarizers, causing the dark appearance of crossed polarizers to show. The more the molecules are twisted, it produces a better contrast and viewing angle.

Since less power is needed to move molecules than to energize a light-emitting device, LCDs replaced the light-emitting diodes (LEDs) in digital watches in the 1970s. Eventually, LCDs were used for monochrome displays and still are and in the 1990s, color LCD screens caused sales of laptop computers to explode. In 2003 to date, more LCD monitors were being sold for desktop computers than the bulky and space consuming CRTs.

Organic LED’s are seen as the display technology of the future mainly because of the cost factor which is way cheaper than current display technologies. With the old and reliable CRT on its way out, slowly being replaced first by plasma and then LCD’s, the evolution of technology makes life easier and a whole lot lighter.
One of the enticing facts about OLED’s is the ability to print one out with a device as simple as your desktop printer, further processed into any shape of display that can be thought of. Read the rest of this entry »

Everybody knows how annoying a scratched computer LCD display can ruin your day or even cross your eyes, straining it too much causing headaches. Luckily, there are protective display films that can be fitted onto them to prevent such incidents. These scratches are actually on a protective acrylic sheet that sits above the actual glass screen to prevent such incidents and they can also protect you from prying eyes with special treatment that prevents viewing at an angle that would be off the front of the screen. This prevents you from getting victimized by identity thieves who sometimes prey upon unsuspecting people who uses their portsbles out of the office. Read the rest of this entry »

Today’s LCD displays (TV’s or Monitors) are already power saving with most rated with Energy Star abilities. They are however still quite capable of eating a lot of power due to the back light which is most often an extremely thin and flat fluorescent tube that needs quite a lot of power to initiate the charge. That is why it is vital you unplug the unit or get a power strip with individual power switches to turn-off these gadgets when not in use. Read the rest of this entry »

While the LCD monitor prices are slowly going down, it’s still pays to take care of a LCD screen. Just going to the shop and buying another one is a hassle altogether, not to mention the money that goes down the drain. So to help you take proper care of your LCD monitor, here are two basic tips that should help you out:

1. LCD is not equal to CRT.
In cleaning your LCD monitors be sure to stay away from AMMONIA based cleaners you used to use with your old monitor. LCDs are cleaned much like lenses of cameras and eyeglasses – with a special solution and special cloth. Also only clean it when it’s off.

2. Don’t poke it.
Poking your LCDs will case dead pixels, which will destroy your monitor in time and puts IRREPAIRABLE ugly black spots all over it.
