Abstract
An object is to provide a technique capable of suppressing a power consumption of an LED. An LED display device includes voltage supply parts, which can supply a multiple types of voltages being different from each other and a driver which drives an LED display using the multiple types of voltages. The driver switches a combination of an LED array in a lighting target group which is one of the plurality of groups being subject to lighting-up and the multiple types of voltages which should be supplied in parallel with the LED array, under a time sharing control, and turns on some LEDs, which should be turned on by the voltages which should be supplied to the LED array, in the plurality of LEDs included in the LED array in the lighting target group.
