The tech that makes your computer display or TV work can seem incomprehensibly arcane, millions of tiny dots compressed into a thin sheet, somehow supplied with power and light and colour. Trends come and go, as once we were enthralled with the intense picture quality of plasma screens, only for them to fall away, replaced by lighter and less power-hungry methods of making a moving picture. Legends even tell of huge, boxy things that used magnets to steer a beam of electrons that made the inside of the screen glow, but it was so long ago we’re not sure they were even real.
