CHROMATICALLY-ADJUSTED DISPLAY ELEMENT WITH REFLECTIVE HOLOGRAPHIC DIFFUSOR |
摘要 |
Reflective image-providing displays illuminated with chromatically-adjusted holographically diffused light are provided. In one particular and preferred embodiment, a liquid crystal display component is presented comprising a liquid crystal display element backed with a reflective transmission holographic diffuser. Chromatic adjustment is effected by the inclusion in said liquid crystal display component of a compensatory filter layer of relatively low density designed to restore the ambient color balance of input light, the balance being otherwise upset by transit through said liquid crystal display element. Achromatically illuminated images of good contrast are displayed and viewed from the liquid crystal display component under ambient lighting conditions.
