发明名称 METHOD FOR DISPLAYING TIME AND DEVICE FOR EXECUTING METHOD THEREOF
摘要 <p>The present invention relates to a method for displaying time and a device for executing the method thereof. The method for displaying time comprises the following steps: generating magnetic fields by an electric power supply portion through inductive coupling of an electric power supply coil, and a first coil of a first arrow driving portion and a second coil of a second arrow driving portion; supplying electric power to the first arrow driving portion and the second arrow driving portion using the magnetic fields by the electric power supply portion; and supplying the electric power to each light emitting device provided at a first arrow and a second arrow, by the first arrow driving portion and the second arrow driving portion so as to turn on the light emitting devices. Therefore, the invention continuously emits light at a constant luminance even at night without having a user move to turn on a standing lamp or an indoor light in case of indoor use, and thus the invention has the effect of a night lamp and it is possible to easily check time even at night.</p>
