Liquid Crystal Display

Liquid crystal display, also known as liquid crystal diode, is one of the most advanced technologies available at present. Typically, an LCD monitor consists of a layer of color or monochrome pixels arranged schematically between a couple of transparent electrodes and two polarizing filters. Optical effect is achieved by polarizing the light in varied amounts and making it pass through the liquid crystal layer. At present, there are two types of LCD technology available. These include the active matrix or TFT and a passive matrix technology. Among these, TFT technology is more secure and reliable, and generates better picture quality. On the other hand, passive matrix has a slow response time and is slowly becoming outdated.

In recent times, LCD monitors have become increasing popular with consumers. Some major advantages of using an LCD monitor include:

These monitors are compact, lightweight, and do not consume much desk space.
Secondly, these monitors do not consume much electricity and can even be operated by using batteries.
Also, the images transmitted by these monitors do not get geometrically distorted and have little flicker.

However, LCD monitors do have certain disadvantages. Most importantly, these monitors are very expensive. Secondly, image quality is not constant when viewed from different angles. Also, an LCD monitor’s resolution is always constant. Any alterations can result in a reduced performance.
