ABSTRACT:
A field-emission display includes a faceplate having an inner or outer surface covered by a depixellation film containing a large number of graded refractive index microlenses. The depixellation film averages or spreads the light illuminated by each pixel so that the illumination intensity is relatively constant across the surface of the pixel. As a result, the viewing characteristics of the field-emission display are improved.
