Abstract
An information display device, after detecting the completion of charging of a battery, counts the number of times that display content of a nonvolatile display part is rewritten. Based on the number of times of rewriting processing, the information display device derives information on a remaining battery capacity of the battery. The information display device displays the derived information on the remaining battery capacity.
Claims6
An information display device comprising:
- a nonvolatile display part which is configured to maintain a display even when the supply of electricity from a power source is cut;
- a display processing part which is configured to execute rewriting processing of a display content displayed on the nonvolatile display part;
- a charging part which is configured to charge a battery which is used as the power source;
- a charging completion detection part which is configured to detect the completion of charging of the battery by the charging part;
- a rewriting-number-of-times counting part which is configured to count the number of times of the rewriting processing executed by the display processing part after the completion of charging of the battery is detected by the charging completion detection part;
- a remaining battery capacity deriving part which is configured to derive information on a remaining battery capacity of a battery based on the number of times of rewriting processing;
- and
- a remaining battery capacity display processing part which is configured to execute display processing of the information on the remaining battery capacity derived by the remaining battery capacity deriving part.
