Wasn't there a Panasonic or Sony TV that came out not too long ago that radiated light behind the set? Only as I remember it, it wasn't a white light, it would radiate the main color on the display at the time, so it was constantly changing. In the commercial they touted the back light as making the whole experience more involving of the viewer. However it seems they missed the whole purpose of it if they were using colored lights instead of a constant white source like you are.
Very interesting indeed.
