PURPOSE:To solve such problems that it is hard to lead out terminals since the terminals are too many in a static driving system so it comes to hard to constitute a driving circuit since a current value is large in a dynamic driving system, when driving the color LED display device on which light emitting diodes are arranged in the row and column direction. CONSTITUTION:Dot signals DS1-DS256 corresponding to the dots of a color LED display unit are provided and chrominance signal lines R, G, and B corresponding to light emission colors are provided; and light emission diodes which emit light of the same colors are driven at a time while a period is divided by the light emission colors. |
