Everything About LCD Monitor

LCD computer screens consist of active-matrix polarizers and panel. The panel and the polarizers, when combined may act as a pixel-level light filter that is electrically-controlled. The active-matrix panel and polarizers are located directly in front of the backlight. The backlight is a uniform and wide-area light source that usually consist of cold-cathode flourescent lamps or CCFL. Along with the CCFL’s is a lightguide and a diffuser. Around a dozen rows and columns of driver chips is connected to the panel. The panel addresses the picture data’s display. These chips are driven by the monitors electronics.

Another important thing to consider about caring for your LCD monitor is the proper handling.
1. Keep sharp or pointed objects away from your LCD screen. It might damage the soft film on the surface of the monitor.
2. The LCD is made up of glass. This may be broken if your LCD monitor is bent due to falling or strong shock.
3. It is recommended that you use soft gloves in handling your LCD monitor.
4. If your LCD monitor has a back light wire, avoid stretching or bending it.
5. Be sure to use Isopropyl alcohol in cleaning the surface of your LCD monitor. Not Ethyl alcohol!

The LCD or the flat panel computer displays are the latest offering in the desktop computer industry. It has been used for years in the portable and notebook computing markets, but recent developments have increase performance and size while reducing costs making them viable in the desktop environment. The LCD monitors are lightweight, extremely thin and uses less power than the CRT based monitors.

The LCD displays are marketed by its actual screen dimensions. The measurement of the displayable area of the screen is from the lower corner to the opposite upper corner of the display. LCD screens can display only a single given resolution which is referred to as the native resolution and this is the physical number of horizontal and vertical pixels that make up the LCD matrix of the display. Setting a computer display to a resolution lower than this resolution will result in fuzzy images.

We should also consider the environmental factors that may affect our LCD monitors’ performance. Here are some helpful facts:
1. If your LCD monitor is exposed to dust, it may cause electrical short inside. This would then result to malfunctioning.
2. Your LCD monitor may be discolored if it is contaminated by any kind of liquid substance such as humid. Liquid substances may enter the device and this would most probably cause electrical failure and corrosion that could possibly lead to improper functioning.
3. Dust may also cause scratches to the surface of your LCD monitor especially when wiping it with a dirty piece of cloth.

Various computer companies has shifted its production from cathode ray tubes (CRTs) to liquid crystal display (LCDs) to meet the demands and wants of its consumers. The evolution of computer monitors brought users to a more convenient and clearer resolution of pictures, videos, and colors. Clearly, CRTs is phased out and the LCDs have dominated the computer market.

It is very important for us to know the different elements that may affect the performance and quality our LCD monitors. Here are a few ideas that we should consider:
1. The brightness and response time of the LCD monitor are affected by the temperature of its location. At low temperatures such as 10 degrees celsius or even lower, your LCD monitor may fail to obtain proper display.
2. During conditions of humidity or high temperature, the lifetime of your LCD monitor may be shortened.
3. Exposure to drastic changes or shifts in temperature may affect the polarizer of your LCD monitor, thus harming its quality.

6. In LCD monitors, motion-blurs may occur. CRT monitors usually portray motion better.
7. The peak brightness of LCD monitors are limited by backlight and the still photos or videos may sometimes appear flat. CRT monitors have high peak brightness. CRT monitors also have the capability to provide “life” and “sparkle” to movies, videos or photos.
8. LCD monitors have he tendency to encounter or develop “stuck” pixels while CRT monitors have no problems regarding this since CRT’s are not pixel-based.
9. LCD’s have fixed inherent resolution while the CRT’s may support multiple resolutions equally and fairly well.
