Abstract
Disclosed is an electronic device including: a display; at least one optical lens configured to change an optical path of light generated in the display at a fixed refractive index; a prism configured to reflect the light, which has passed through the at least one optical lens, at least one time to guide the light to a destination point; a variable lens positioned in the optical path of light between the display and the destination point, a refractive index of at least a portion of the variable lens being changed by a control signal to change at least a portion of the optical path of light; and a controller configured to generate the control signal. An optical path of light generated in the display may be changed by the variable lens whose refractive index can be changed.
