LCD Displays Versus LED – Head To Head Comparison
If you are under the impression that you know everything about the functioning of LCD display screens you might have something new to learn in this article. there are many customers who believed that LCD is better technology because it is less expensive. It is flat and occupies much lesser space when compared to conventional color televisions in Visual Impact Productions. There are some basic similarities as far as LED and LCD technologies are concerned. The technology is prominently the same in the area of image reproduction. Both the technologies make use of a liquid crystal cell. This cell is placed in between polarized filters (two in number). Electricity flows from one filter to another. However it is here that the similarity in technology ends. The backlight that is used for illuminating the liquid crystal is different. Cathode fluorescent lamps are used in Detroit LCD screens where as incase of LEDs individual light emitting diodes are used.
Performance Oriented Differences
The above paragraph discusses in brief the technological area in which both these lighting systems differ. We will now have a look at some performance related area where there are significant differences between the two. The quality of images is much better in a LCD monitor because of the simple reason that each pixel is a light emitting diode in itself. Hence the quality of imaging and video is unmatched. It is also very eco-friendly because it emits much less heat and therefore does not contribute to ozone depletion. In terms of energy efficiency there is no doubt that LED is a much better and advanced technology.
Comparison In Cost
Though buying a LED TV would be a much more expensive proposition it should not be looked from one angle alone. When you start using LED instead of LCD you will be certainly saving lot of money by way of savings in electricity bills. According to some rough estimates the savings in electricity could be around 40% to 50% in many cases. This will translate into savings worth thousands of dollars when it is looked at from the long term perspective.
Additionally repairing and maintaining a LED TV is always much less expensive when it is compared to a LCD TV. In a majority of the cases, if the LCD screen gets damaged it may have to be replaced with a new one. This is because the replacement of spare parts would be almost the same as buying a new one. On the other hand repairing LED TV will not be a big problem in most of the cases.
Taking the above points into accounts there are reasons to believe that LED is a much better option though you may have to spend more initially when you purchase it.
