As you may have noticed recently, manufacturers are releasing LCD computer monitors that are powered by LEDs instead of the usual CCFLs. What does this mean? Well, just like with usual lighting, LEDs are more efficient than other forms of lighting, which is one of the reasons why LED-powered HDTVs are also starting to appear. From Viewsonic to Dell and Apple, almost all manufacturers are starting to make LED-powered computer monitors. Just like HDTVs, computer monitors will consume a lot of electricity over their lifetime, which is usually counted in years, so it makes sense to power them with energy-efficient LEDs. Another benefit to using LEDs in computer monitors is that they can be very thin compared to CCFL, and their product lifetime is also longer. Unlike CCFL backlights, the manufacturing of LEDs does not require any mercury, and these types of HDTVs and computer monitors can be up to 50% more energy efficient than the latest ENERGY STAR specifications.
The most obvious LED monitor on the market right now is the 27" LED Apple Cinema Display, but there are cheaper alternatives from Viewsonic and Dell, but not in the same size. The Viewsonic VX2450wm-LED is a 24-Inch monitor powered by LEDs. It costs around $200 compared to the Apple monitor, which costs $999.
The same is true for HDTVs. A few models are currently available from Sony, LG, and Samsung, but more will crop up as the manufacturing costs go down. LEDs are the future of lighting, but they're currently still expensive to setup and take a long time before they recoup your initial investment. This is especially true when compared to CFL bulbs, which are lot less expensive at the moment and still save you similar amounts of money compared to LEDs. So you can expect to pay anywhere from $2,000 to $4,000 for these LED energy-efficient HDTVs in sizes of 52" to 55".
