Incandescent lamps work on the principle of electrical heating which both types of current can do. Semiconductor devices generally use DC because direction of the current is important. TV screens are not continuous light; it is a kind of flickering light. In a previous post, this has been discussed with respect to cats and dogs. You may find it useful. | |
