My old (and still awesome) friend Derek Heckler sent me this video that you all have to watch – seriously, watch this video! Bill Hammack (from Engineer Guy, also a professor at the University of Illinois) made this video, and I have to say that it is one of the best videos on breaking down the internal working components of light and optics in LCD monitors!
Also, make sure to check out Bill's videos on Youtube, too – hours and hours of awesome watching there!
