Here's an intriguing video comparing LG's new NOVA technology for smartphone screens to Samsung's Super AMOLED tech. Supposedly, the NOVA screen is much brighter and more efficient on battery life. In fact, they claim that the white colors on the NOVA screen use half as much energy as whites on the Super AMOLED, and that overall the NOVA is 50% more efficient than an iPhone screen. But, we don't have to take their word for it, at least in the better brightness comparison, because the video above gives us a pretty good look. Sound off in the forums which screen you think looks 'better'.
