Multi-View Display Optical Members to Reduce Reverse Viewing

The patent applies local quality by using different optical members with specific curvature characteristics in different regions and orientations. The first and second optical members have convex lens parts with curvature in the first direction (orthogonal to facing direction) but no curvature in the second direction (facing direction), creating anisotropic light control that allows wide viewing angles while preventing reverse viewing through directional optical manipulation.

The patent employs asymmetry by configuring the convex lens parts of the first and second optical members to have line-symmetric extending directions with respect to the second direction. This asymmetric yet symmetric arrangement enables the optical system to control light paths differently in different directions, achieving wide viewing angles while blocking reverse viewing paths.

The patent applies segmentation by dividing the optical control into two separate optical members (first optical member and second optical member) positioned on opposite sides of the display panel. Each optical member contains multiple convex lens parts arranged in a specific pattern, segmenting the light control function across multiple components rather than using a single complex optical element.

The patent uses curvature selectively in the optical members by configuring convex lens parts with curvature in the first direction (orthogonal to facing direction) but no curvature in the second direction (facing direction). This partial curvature approach achieves light diffusion and viewing angle expansion without requiring fully curved or complex three-dimensional optical surfaces.
