More Information
Summary:An apparatus includes a display screen that includes OLED pixels disposed at a particular pitch in a first plane. A light projector includes light emitting elements disposed in a second plane parallel to the first plane. The light emitting elements are disposed at the same pitch as the OLED pixels or at an integer multiple of the pitch of the plurality of OLED pixels. The light emitting elements are operable to produce light at a wavelength for transmission through the display screen, and the first and second planes are separated from one another by a distance D such that d2=2*(λ)*(D)/(N), where d is the pitch of the OLED pixels, λ is the wavelength, and N is a positive integer.
