Is Now the Right Time?
Posted on 6:49 AM by Impress Rabi
With LCD flat panel prices dropping and the growing concern for the environment, is now the right time to replace those old energy hungry CRT monitors?
3 years ago, an LCD flat panel would have set you back at least £250. Now you can get a good quality 17” panel for under £100. However, price is not the only reason why so many businesses are upgrading to LCD panels. Some of the other compelling reasons are:-
Power Consumption - On average, LCD panels use 60% less energy than the traditional CRT (Cathode Ray Tube) monitors. In a recent study, it was estimated that if every business in the UK was to upgrade to an LCD flat panel, it would save 3 billion kWh of power consumption which is the equivalent of the total power consumption of 1 million households or the power production of about 3 nuclear power plants.
Personal Health & Comfort - The main benefit that LCDs have when it comes to comfort is the reduced strain on your eyes. The reduced glare on the screen's surface, and the elimination of a typical CRT's "refresh", can prevent your eyes from getting tired from extended use. A CRT monitor redraws the image on the entire screen as it refreshes, whereas an LCD monitor only changes the necessary pixels during a refresh.
Increased Viewing Area - With an LCD panel the whole screen area is active and viewable so there is no image loss at the boundaries, whereas the viewable screen area of a CRT is smaller than the monitor face. Consequently a 15” LCD can give the equivalent area of a 17” CRT, and a 17” LCD the equivalent of a 19” CRT.
Reduced Radiation - There may also be the unquantifiable effect of reduced electromagnetic emissions on LCD monitors. The exact impact of electromagnetic emissions may not be fully understood, but in general LCD monitors produce significantly less emissions than the old style CRT monitors.
Size - One reason that LCDs have gained in popularity is because of their small foot print. The overall size and weight of CRT monitors far exceeds that of LCD monitors. CRTs share the same image processing technology with tube televisions, and therefore share the same bulky style of housing. Desktop real estate is precious, and an LCD will require only a small fraction of the depth that a CRT would require. And if there isn't even enough room on your desk for a slim LCD monitor, the low weight makes them perfectly adaptable to be hung on the wall, or from a radial arm mount.
