Q:

Dear 100 Hour Board,

Why are all the colors off when looking at an angle at a liquid crystal display? I recently flew Jet Blue which offers complementary TVs on each seatback, but looking at my neighbor's tv produced off colors unless you looked somewhat straight at it. Why?

A: Imagine a set of blinds (vertical or Venetian). If you open them up and look at them straight on, you can see out the window. But if you look at them from an extreme angle, then you can't see through the slits because the material overlaps. LCD's work by passing red, green, or blue light through a very, very thin slits and using the liquid crystal to control how much of the light gets through. If you look at them straight on, then you can see all the light coming through the slits. But if you look at them from an angle, some of the light gets blocked, causing color distortions.
