Abstract
A method and apparatus for minimizing diffraction effects on flat panel displays. The flat panel display includes a plurality of display elements, each display element including a first structural feature having an edge and a second structural feature disposed on the first structural feature. The edge of the first structural feature causes incident rays from a point light source to generate diffraction effects due to the Fresnel reflectance difference in the boundary between the first and second structural features. The display further includes an edge texture on the edge of the first structural feature to minimize the diffraction effects into a more diffused diffraction pattern.
