A rotational light emitting display apparatus is provided. The rotational light emitting apparatus device allows static and animated images and instruments to be displayed on dynamic screen. The display is refreshed repeatedly to take advantage of the persistence of vision property of the human eye. The illuminating element of the apparatus includes a plurality of light emitting elements arranged in a line. Display refreshing is accomplished by mounting the apparatus on a rotating object, so that the line of light emitting elements lies along a radial direction. In this way, each of the light emitting elements traverse a circular path, while being flashed on and off to produce the desired display.
