An electronic device, and a corresponding light emission control method for the electronic device, emit light by utilizing recombination of electrons and holes the device and method input a pulse-shaped driving signal having a duty ratio higher than or equal to 0.7 and lower than 1.0 and thereby causing light to be emitted intermittently. When an electron density is denoted by n, a hole density by p, a thermal velocity of electrons by Vth:n, a thermal velocity of holes by Vth:p, an electron capture cross section of a defect level by σn, a hole capture cross section of a defect level by σp, and a pulse width of the driving signal by W, the input driving signal has a pulse width W that satisfies W
