Electronic device including variable capacitor including photo-conductive material and method for controlling the same

A capacitor device comprising:

• one or more light sources;
• a control circuit configured to control the one or more light sources;
• a first conductive layer;
• a second conductive layer formed to be opposite to the first conductive layer, the second conductive layer including:
• a plurality of conductors that are electrically separated, and
• one or more photo-conductive members positioned to correspond to the one or more light sources in a state where the one or more photo-conductive members are connected between the plurality of conductors;
• and
• an insulating layer interposed between the first conductive layer and the second conductive layer.
