摘要：A driving method of a light emitting device including visible light emittingelements is provided. In a first visible light communication mode, a first portion of the
visible light emitting elements is driven and a second portion of the visible light emittingelements is idled for the first portion of the visible light emitting elements having a firstcurrent density. In a second visible light communication mode, each of the visible lightemitting elements is driven so as to have a second current density. An illuminationbrightness difference of the light emitting device between the first visible lightcommunication mode and the second visible light communication mode is smaller than15%.
