LCD TVs are a rage these days; largely because they are compact, convenient and the picture quality is great. But because of the substantial cost of the investment, it is crucial to make an informed decision, is case you are planning to buy one.
The twisted nemantic (TN) is the most commonly used type of liquid display used in a wide range of applications these days, including TVs, monitors and computers. A unique feature of this arrangement is that it reacts in predictable ways with light currents, depending on the voltage of the current supplied. Any LCD setup comprises of tiny particles called 'pixels' that are manipulated to present information of produce images, as and when they are turned on by the passage of light. Since, the pixels allows all wavelengths to pass through, the full light spectrum can be maneuvered to produce the desired color.
The obvious advantages of a LCD screen include shaper, brighter images, wider viewing angle and that it functions well under any light conditions. One issue that you need to be aware of is that the picture produced by an LCD screen depends on its dot-pitch-the term refers to the distance between sub-pixels of the same color adjoining pixel strands. The lesser the distance, the sharper, more realistic and detailed the image.
LCD screens come with in-built tuners and speakers, more often than not. This means that they are largely plug-in and watch devices. For this reason, LCD screens are ideal when space availability is one of the issues at hand.
The average life span of any of these displays is about 60,000 hours, which roughly means that even if you watch TV for 24 hours a day you would still take a out 7 years to wear out your LCD TV. Of course the light-source of your LCD is another matter. The latter is crucial especially for maintaining the 'white-balance' in your image. As the bulb ages the images can develop imbalances like red tints etc. In this regard, it crucial to invest in branded displays.
Even though you might end up paying more, it will be worth the investment. In some cases the warranty of the light source can be shorter than for the display. This in turn means that you will have to buy a whole new display because the coverage on the backlight has expired. In some sets the light is replaceable while in others it is built in the set itself. It is thus important to do an extensive research on the backlighting system of your prospective buys, about how it is structured and warranted.
