摘要： A frontlit touch panel for use with a reflective light valve, comprising a front light guide having at least one light input face that supplies light to the guide, a viewing face, a light output face opposite the viewing face, and at least one component of a touch-sensitive transducer, the light output face having a light extraction layer thereon having a substantially flat light exit face and containing buried reflective facets that extract supplied light from the guide through the light exit face. The touch panel can be used with a light source, reflective light valve and suitable control electronics to form a compact, efficient illuminated touch panel display assembly.

摘要： A method includes providing a polymerized optical film structure having a microstructured surface, forming a scratch having a length on the microstructured surface to form a scratched optical film, illuminating the scratched optical film to form an illuminated scratch, measuring a plurality of scratch contrast ratio values along the length of the illuminated scratch with a detector, and determining a maximum scratch contrast ratio from the plurality of scratch contrast ratio values along the length of the scratch.
