摘要：
A textured surface on the inward side of the high refractive index transparent front sheet in a reflective image display may lead to a display with a wider viewing angle. The textured surface may be in a random or a patterned array and may comprise microstructures that exhibit total internal reflection and Fresnel reflections. Electrophoretically mobile particles of similar size to the microstructures may improve coverage on the front sheet and improve frustration of TIR leading to darker dark states.
