Abstract
A display backlight includes an illumination layer and an optical layer. The illumination layer includes a two-dimensional array of light sources, which generate illumination light. An image of the illumination light is captured and analyzed for light uniformity. In response to the analysis of the illumination light, ink patterns are printed on the optical layer of a display backlight to increase light uniformity of the illumination light.
