Color Displays

Our eyes perceive a continuous image when we look at a screen, but in fact, images are made up of tiny points of light called pixels. Look through a lens to see the individual pixels on the screen, and then turn up the magnification to see that each pixel is composed of red, green, and blue subpixels. Play with a macro-scale model that uses a tricolor LED to represent how the color of a pixel can be tuned to any color of the rainbow.
