PROBLEM TO BE SOLVED: To provide a feeding method of electronic display device by which display/logic units can be fed stably with electricity with small voltage fluctuation. SOLUTION: In a feeding method by which an electronic display device constituted of (n) pieces of display/logic units 1, 2,..., (n-1), and (n), a power supply board 10, bus bars 12, 13, and 14, etc., is fed with electricity, the bus bar 12 is connected to the plus-side output of the board 10 and the bus bar 13 is connected to the bus bar 12. In addition, the bus bar 14 is connected to the minus-side output of the board 10 and the units 1, 2,..., (n-1), and (n) are connected to the bus bars 13 and 14. Since the distances from the bar 10 to the conductors of the loads are equal to each other, the voltages V1, V2,..., Vn-1, and Vn applied across the units 1, 2,..., (n-1), and (n) from the board 10 become equal to each other. |
