Abstract
A multi-display system (e.g., a display including multiple display panels) includes at least first and second displays (e.g., display panels or display layers) arranged substantially parallel to each other in order to display three-dimensional (3D) features to a viewer(s). An optical element(s) such as at least a refractive beam mapper (RBM) is utilized in order to reduce moiré interference.
Claims23
A display device comprising:
- a first display in a first plane for displaying a first image;
- a second display in a second plane for displaying a second image, wherein said first and second planes are approximately parallel to each other;
- a beam mapping element located between the first and second displays and comprising a plurality of microlenses configured to direct rays output from the second display in a pseudo random manner through sub-pixels of the first display and toward a viewer;
- and
- wherein each of the microlenses has a diameter that is less than a length and a width of a subpixel in the second display.
