<p>PURPOSE:To make an AC/DC converter incorporated in individual unit small in capacity and size and to manage an AC power source equipment connecting each unit small in capacity. CONSTITUTION:In a motion visualization type display device mounting a light emitting array 3, image data output means 8, 9, 10, 11, 12 and a timing control means 7, etc., on a unit case, so a power source connector 14 connecting an external AC power source cable 5, the AC/DC converter 15 converting AC power source applied to the power source connector 14 to a prescribed DC, a secondary battery 17 and a charge control circuit 16 charging the secondary battery 17 by the DC output of the AC/DC converter 15 are mounted on the unit case. The power source of a light source in the light emitting array 3 is obtained from the secondary battery 17, and the power sources of logical circuit parts in the image data output means and the timing control means 7 are obtained from the output of the AC/DC converter 15.</p> |
