Abstract:
1. An information displaying device comprising: a display portion that displays an image based on display information and a predetermined driving voltage; an information-setting portion that is connected to a plurality of slow starters with each comprising a register, wherein the information-setting portion is configured to set a boost target value of the driving voltage of the display portion in each of the registers; a voltage output portion that divides a power supply voltage to generate output candidates of the driving voltage having plural output values, each output value having a different voltage value and a different corresponding period of energized time; a voltage selection portion that selects the output values, successively, based on a predetermined selection control signal from a lower rank of the output candidates of the driving voltage in the voltage output portion to a higher rank thereof and boosts the driving voltage; and a boost control portion, wherein for each successive selection performed by the voltage selection portion, the boost control portion is configured to:
