Abstract
A display device is described and includes a first display screen including a mask pattern of a pixel. The display device includes a second display screen including the mask pattern, wherein the second display screen is located further from a front of the display device than the first display screen, wherein the front of the display device is closest to a viewer. The display device includes a diffraction element configured to copy the mask pattern of the second display screen into one or more viewable copies in order to minimize moiré interference with the mask pattern of the first display screen.
