Abstract
Disclosed is an electronic device that includes a layer, a light source that irradiates light to the layer from a lower side of the layer, a regulator that supplies a voltage to the light source, and a processor electrically connected with the regulator. The processor determines an output voltage of the regulator based on information about the layer.
