LCD Monitors: Buying Guide

Flatscreen LCD Monitors are now the displays of choice for computer users. But what exactly are LCD monitors and what special features do they possess? Here is the low down on LCD monitors and what you should look out for when buying one.

How they operate
Liquid Crystal Display (LCD) Monitors work by passing an electric current through kinematic liquid crystals. The liquid crystal don’t emit light themselves, but work by modulating the light that is supplied by an external source. This light also passes through p two polarizing filters to create images.

Comparison between former and modern LCDs
The earliest LCDs were passive-matrix, which uses integrated circuits to charge a given pixel. However, modern LCD monitors use active-matrix which use thin film transistors to motive the pixels, improving on the slow response times that plagued passive-matrix displays.

Resolution
Each pixel in a LCD has three sub-pixels consisting of the primary colors of red, blue and green. Through the modulation of the voltage applied, each sub-pixel can be made to display over 256 shades, allowing the LCD to display an extraordinary 16.8 million colors.

Modern LCD monitors use an extremely high number of transistors. A typical monitor that supports resolutions of 1,024 x 768 will use over 2 million transistors etched onto the glass. A malfunctioning transistor will create a ‘bad pixel’. Most active-matrix LCDs have a few ‘bad pixel’ on the screen.

Although the cheapest LCD monitors are illuminated by fluorescent tube, better quality newer ones have LEDs which provide far better quality thanks to better control over individual pixels.

Aspect Ratio
Although viewing angles used to be restricted on LCD displays, technological improvements have enabled modern displays to have a 180 degree horizontal viewing angle although the vertical viewing angles continues to be restricted, mainly due to cost reasons.

LCD displays come with different aspect ratios, which is the ratio of width to height. Most modern displays have an aspect ratio of 16:9 to accommodate high-definition film, although 4:3 ratios are also common.

Advantages
Compared to CRT monitors and plasma TVs, LCD monitors consume much less power, enabling it to be used in battery-powered devices such as laptop computers. Their slimmer profile and great picture quality, combined with their environmentally friendly operation go a long way in explaining their great popularity.

When choosing a new LCD display, try and buy one that has LED lighting for even better quality and energy efficiency.
