About LCD Monitor

LCD means Liquid Crystal, the technology behind these popular flat panel displays. LCD monitor differs from a traditional CRT monitor, it has a large area with a depth of several cm and weighing 30 - 50 pounds (13-23 kg) or more, while LCDs are usually 1-3 inches (2.5 - 7.5 cm ) thick and weighs less than 10 pounds (4.5 liters).

LCD screens in notebooks until the technology improves to make the leap to desktop monitors. LCD display consists of five layers: a backlight, leaf tinted glass, a "mask" in the pixels of the color, the layer of liquid crystal solution on the basis of the wired network coordinates X, Y, and the second part of polarized glass. By manipulating the exact directions through the crystal, electric charges and voltages in varying degrees, the crystals act like tiny shutters, opening or closing in response to stimuli, the level of light-colored dots on the screen lights up, creating an image.

As LCD technology developed various methods for manufacturing non-ferrous arise. O Active-matrix TFT (thin film transistor) technology, and produces color images as sharp as all CRT and generally superior to passive-matrix technology.

Important dates, when purchasing an LCD monitor on the contrast, brightness (or "nits"), viewing angle and response time.

Contrast ratio is the comparison of differences between the values of bright white and darkest black values. The higher the contrast ratio is less than flowers "money." In the standard set for the lower end models of 350:1. Many experts recommend that the contrast ratio of 500:1 and higher.

LCD monitor brighter than CRT monitors, so that consumers little reason to create a model very bright. Brightness in nits or candelas per square meter. Somewhere between 250 to 300 nits is standard. When the night is much higher, it is likely to end the brightness down.

In the viewing angle is especially important when there is a lot of people just a monitor at any given time. There is one vertical and horizontal viewing angle of the specification, which refers to the extent you have died from the picture before will be erased. On the other hand, usually in conjunction with a broader perspective. Many recommend that the angle of 140 degrees to 120 degrees horizontally and vertically. Angle, in general, the better.

Response time is measured in milliseconds (ms), and refers to the time required for full marks from white to black and vice versa. Values less response time faster and easier, especially for games and video. If the reaction is slow, the "spirit" or "trailer" can occur with fast moving images such as painting a screen overlay. The maximum response time must not be used for more than 25ms, 17ms, and more. Many players do not report phantom with a LCD monitor with a response time 16 ms or less.

LCD with one-third to half of electricity from CRT counterparts. They are much easier on the eyes, 90% less space, weight, and only a few pounds. In addition, emit much less radiation, lower frequency of CRT. This makes LCDs good choice for almost everyone, and is ideal for people who have the whole day in front of the screen. Color can change the color, how to reach the outer limits of the angles, especially the displays with narrow viewing angle and low contrast. For this reason, the most demanding graphics professionals who require a color match, regardless of the view that the use of CRT, LCD, but settled in this context.

LCD monitor is available in standard sizes from 15 inches to 21 inches or more. The screen of the same nominal size of the screen, as, unlike CRT monitors. Thus, the 15-inch LCD has a 15-inch display.

One possible weakness of LCD display with backlight. Many monitors have a 3 year warranty, but they are 1 year on the backlight. Models with 3 years warranty, the backlight is usually worth a little more, but probably resulted in additional investment.
