Abstract:
An electronic display assembly includes a display element and a corrective element coupled to the display element. The display element has a first plurality of sub-pixels of a first type and a second plurality of sub-pixels of a second type. Two adjacent sub-pixels of the first plurality of sub-pixel are separated by a sub-pixel distance. The corrective element has a plurality of features configured to diffuse light emitted by the first plurality of sub-pixels such that an apparent distance between the two adjacent sub-pixels of the first type, viewed at a viewing distance away from the electronic display assembly, is less than the sub-pixel distance.
