ABSTRACT:
According to one embodiment, an electronic device includes a housing, an operation area, at least one display, an input detector, a light source device, and a controller. The operation area is provided on an outer surface of the housing. The display is located in the operation area, and includes a first indicator and a second indicator made of a light transmissive material. The first indicator corresponds to a design that indicates operation content, while the second indicator is located in a position not covered by an operation tool with which operation is performed on the first indicator and indicates operation state. The input detector faces the operation area in the housing and detects electrostatic capacitance in the operation area. The light source device emits light to the display in the operation area. The controller controls the light source device based on a variation in electrostatic capacitance detected by the input detector to turn on or off at least the second indicator.
