Heat build up on an LCD touch screen surface.?
Consider how light reflects off a Black or White object. A black object absorbs the light where its converted to long wave IR (Heat).
Is this effect the same for a color LCD screen whihc uses LED backlights? Assume that 1/2 of the screen is displaying white and the other 1/2 is displaying Black. If an incadescent lamp is placed in close proximity to the LCD surface say 6 to 8 inches. Do you think there would be a slight difference in temperature either at the screen surface or a layer just below the surface of the screen?
Think of it another way as vectored light, one vector incomming (to the screen) the other out going (from the screen). Would photons traveling in opposite directions collide and cancel each other out?

the greater heat source would (the light) over power the back light heat. so the surface would be hotter. and consequently filter in through the screen to the interior of the phone. but it is an interesting question.
