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.

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.

The surface LCD monitor, unlike the CRT’s that is made of glass, is made of plastic-like material. Cleaning your flat-screens will only take you a few minutes, but will require special care to avoid any damage.

First, we have to unplug the monitor before attending to it. Use dry soft cloth – the ones used in cleaning eyeglasses – to clean the surface. Gently wipe the surface from left to right. Do this VERY GENTLY. Do not apply any pressure to the screen.

If the dirt doesn’t come off, you can dampen the cloth but not too much. Use distilled water or a solution of equal ratio of white vinegar and distilled water.

The most common irreversible problem on LCD monitors is the occurrence of dead pixels. These are simply non-functioning pixels on LCD monitor. You can easily identify these dead pixels if you have a white background. They look like tiny black spots on your screen.

Dead pixels can not be repaired: they stay where they are for good. So to avoid dead pixels, you better learn how to take care of your LCD monitors. They are much sensitive than the usual CRT monitors because its screens can be easily damaged and scratched.

Some big manufacturers have warranty regarding dead pixels. They can easily replace the unit if it is within the warranty period.

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.

..continued from previous post
Viewing angle. This is the maximum screen projection angle such that display is still in its acceptable definition, neither blurry nor faint.
Color Gamut. Or the color support. How many color set can the LCD monitor display?
Luminance. Is the amount of light emitted by the LCD monitor just right? Is it too bright?
Contrast ratio. This is the luminosity ratio of the brightest color to that of the darkest color. Higher contrast ratio is more favorable than the lower.
Aspect ratio. This is the width-height ratio.
Input ports. These are usually DVI, LVDS, VGA, HDMI or S-video. This depends on your need.

We hope that the specifications we listed were of help to your evaluation.

If you wanted to make the best out of your money, better take a look at this list to know how to evaluate an LCD monitor before buying:
Resolution. Always have a native-supported resolution for your LCD monitor to achieve best display. A resolution is expressed in terms of the number of distinct pixels horizontally and vertically (i.e. 1024×800).
LCD Response time. This is the minimum amount of time needed to change the pixels’ brightness or color.
Matrix Type. The active-matrix looks more brighter and sharper, produces better images than the passive-matrix, and have generally faster LCD response time.
