Abstract
An electronic device includes a power supply; a display including light-emitting diodes ('LED's), a projection lens, and a waveguide arranged in a way such that light emitted from the LEDs is input to the waveguide through the projection lens, and light-outputting efficiency of the waveguide for a first color is higher than light-outputting efficiency of the waveguide for a second color; a memory; and a processor which determines a first driving power for a first LED which emits light of the first color and a second driving power for a second LED which emits light of the second color based on the light-outputting efficiencies of the waveguide for the first color and the second color, and controls the power supply in a way such that the first and second driving powers are supplied to the first and second LEDs, respectively.
