Abstract:
1. A display screen, comprising: a pixel layer comprising a periodic array of light-emitting pixel elements, the periodic array having a pixel pitch of W along at least one direction and operable to emit visible light toward a viewer side of the display screen; and a blur layer disposed adjacent to the pixel layer on the viewer side of the display screen relative to the pixel layer, the blur layer configured to diffuse light emitted by the pixel elements in the periodic array of light-emitting pixel elements, and to suppress spatial frequencies that are greater than a threshold frequency and preserve spatial frequencies that are equal or less than the threshold frequency in images formed by the light emitted by the pixel elements in the periodic array of light-emitting pixel elements, the threshold frequency being greater than 1/W such that spatial frequencies that are greater than 1/W but equal to or less than the threshold frequency are preserved.
