LED backlighting brings a bright future for mobile computing


Having covered HDTV technologies for most of 2005, I know that LED backlighting is about to make a big splash in that space; you can expect brighter screen output, increased contrast and less power consumption. So what does that have to do with mobile computing devices? The key is in the last attribute: decreased power consumption.

Backlighting of a mobile device can eat up a good chunk of power and device manufacturers are well aware that the longer a device can run on a single charge, the more attractive it is to consumers, all things being equal. We won’t see LED backlighting in the mainstream mobile devices until next year, but don’t be surprised to see this feature slowly get rolled into devices later this year. Preliminary research indicates that an LED backlight could increase run-time on a UMPC by 15%.
