Gallery: Energy efficient LED Backlit displays

This is a guest post by D. Salmons over at TestFreaks.

Digital displays are now a way of life. From our TVs and DVD players to our computers and phones, a crisp and bright colour display has become the expected norm.

But having that nice bright display takes valuable energy, and after you multiply all of the devices running it, it becomes a major source of energy use. Fortunately technology has come up with a solution that uses less power.

LED backlighting is a method of backlighting, or illuminating the screen, that replaces the standard Cold Cathode Fluorescent Lamps (CCFL) typically used for this purpose. LED backlighting can be used as actual backlighting behind the LCD screen or side mounted with diffusers in order to keep the display as thin as possible.

It gives a longer life than CCFLs, and they are more efficient with the energy they do use. This means that in most cases the same energy on a LED backlight gives brighter output. Also LED Backlighting doesn't use mercury in its construction, making it more friendly to the environment when manufactured and for eventual disposal.

LED Backlighting can offer higher brightness than comparable CCFLs, resulting in a TV screen that can brighten up the room. It can also offer a wider colour gamut, making the colours on the screen stand out better.

And finally, LED backlighting can offer better dimming control, allowing for a fine degree of adjustment for the end user. Here we look at some of the LED backlight displays that are currently available on the market.
