Abstract
In a display device, wiring for the respective display elements is simplified so that the assembling work and the maintenance work become easy. A large number of display units (,) are arranged in length and breadth directions to form the display device. Each display unit comprises a display element (,) comprised of a light bulb, a regulator (,) comprised of a relay, a non-volatile memory (,) comprised of an EEPROM and a controller (,) including a CPU. For these display units (,), a passage (,) for power supply and a passage (,) for supply of synchronizing signal are drawn. Display information to designate change of display mode in time of light emitting or non-light emitting (ON/OFF) state are stored in memories within the respective display units. The controllers of the respective display units carry out ON/OFF control of regulators on the basis of the display information in synchronism with the synchronizing signal to turn ON or OFF the display elements. If a rewrite signal is delivered to the signal transmission passage, the contents of the respective memories can be also rewritten.
