Light emitting device with optical enhancement structure

摘要

A light emitting device with optical enhancement structure. The light emitting device includes a light emitting element and an optical enhancement structure. Some of the light from the light emitting element is emitted in a diverging manner. The optical enhancement structure have an optical characteristic that directs diverging light from the light emitting element along a path within the optical enhancement structure in a direction towards a normal of the pixel. Light output efficiency is enhanced by means of the optical enhancement structure.
