Arrays of thousands of tiny "super prisms" controlled by robotic muscles could bring real colour to TV screens for the first time, scientists say. The devices, known as electrically tunable diffraction gratings, have been built by researchers in Switzerland. They manipulate light to reproduce the full spectrum of colours on screen, impossible using existing technology.
It won't mean the end of pixel art, becuase it still uses pixels. Pixel artists don't need to worry, but people who want to preserve subpixel rendering might be upset.
