摘要： The present invention is a method and apparatus for showing special characters or figures on a rotating disk. A sensor (e.g. spectrum sensor, metal sensor, magnetic field sensor, mechanical contact sensor and sound sensor) and a plurality of light fittings (e.g. bulbs, light-emitting diodes) are fitted to the rotating disk. The sensor detects the surroundings with inconsistency so that different sensed signals at different points are created when the sensor turns around the central axis once. By deciding the fixing points of the repetitive signals, the rotational cycle of the rotating disk is obtained. After analyzing the rotational cycle, different light fittings on the rotating disk light up at different delay time point. In cooperation with the persistency of vision of human eyes, the preset complicate figures and characters are therefore shown on the displaying surface of the rotating disk when it rotates.
