Abstract
Various arrangements described herein relate to a dual-sided display with improved light scattering. In one embodiment, a display is disclosed. The display includes an inside transparent layer disposed parallel to and spaced apart from an outside transparent layer. The display also includes a liquid crystal (LC) layer disposed between the inside transparent layer and the outside transparent layer and together forming a waveguide that is planar. The display includes ground electrodes disposed between the LC layer and the outside transparent layer and arranged in strips along the transparent layer, the strips being spaced apart and parallel. The display includes inside electrodes and outside electrodes disposed between the inside transparent layer and the LC layer and defining a geometric pattern that is in plane with the waveguide and a light source disposed at an edge surface of the waveguide and providing light along the waveguide.
