Optimization of beam shaping for light emitting displays

Abstract

A method is provided for optimizing beam shaping of a display comprising an array of light emitting elements, each corresponds to a pixel of said display, in order to adjust angular distribution of light pattern in an optical waveguide. The method comprises the step of simulating a luminance distribution for positional and angular characteristics of luminance of the optical waveguide. The method further comprises the step of measuring a luminance distribution for positional and angular characteristics of luminance of the optical waveguide. The method further comprises the step of comparing the simulated luminance distribution with the measured luminance distribution of the optical waveguide. In addition, the method further comprises the step of defining an optimum emission pattern for every pixel for every color of the display based on the simulated and measured luminance distribution.
