3D Display Light-Splitting Assembly Layout to Reduce Moire Fringes

The patent applies asymmetry by staggering the sub-pixels in adjacent pixel repetition unit rows relative to each other in the row direction. This asymmetric arrangement breaks the periodic alignment that causes Moire fringes, while the light splitting structures remain symmetrically arranged. The staggered configuration ensures that light emitting regions from different sub-pixels are distributed non-coincidentally, eliminating continuous dark regions and Moire fringe patterns.

The patent introduces a dimensional change by adding staggered offset in the row direction to the conventional aligned pixel arrangement. While sub-pixels maintain their column-aligned positions, the addition of row-direction staggering creates a two-dimensional displacement pattern that prevents the formation of Moire fringes. This dimensional modification transforms the one-dimensional periodic alignment into a two-dimensional distributed arrangement.

The patent applies universality by designing light splitting structures that serve multiple functions: they split light from multiple columns of sub-pixels simultaneously, enable both 3D and 2D display modes, and work effectively with staggered sub-pixel arrangements. Each light splitting structure corresponds to multiple columns of sub-pixels, creating a multi-functional system that achieves wide viewing angles and high pixel density without requiring separate structures for different display modes.

The patent merges the functions of multiple light splitting structures into a unified arrangement where each structure handles multiple sub-pixel columns. Instead of having separate light splitting structures for each sub-pixel column, the patent combines them into a shared architecture where M light splitting structures correspond to N columns of sub-pixels (with M < N), reducing overall structural complexity while maintaining multi-view capabilities.
