Abstract
A method of manufacturing a display includes coupling light from at least one light source into a front illumination film-based lightguide comprising a pressure sensitive adhesive layer between a core polymer film layer and a diffusely reflective release liner such that light from the at least one light source propagates by total internal reflection through the core polymer film layer, is extracted from the core polymer film layer, passes through the pressure sensitive adhesive layer, diffusely reflects from the diffusely reflective release liner and passes back through the pressure sensitive adhesive layer and core polymer film layer out of the front illumination film-based lightguide; analyzing the light exiting front illumination film-based lightguide from the at least one light source for defects; removing the diffusely reflective release liner from the front illumination film-based lightguide after analyzing; and laminating the front illumination film-based lightguide to a reflective spatial light modulator.
