ABSTRACT:
Various embodiments related to photoluminescent backlighting for a light valve are disclosed herein. One disclosed embodiment comprises a computing device with a light valve having a viewing side and a back side. A photoluminescent material is disposed behind the back side of the light valve, and an excitation light source is positioned to illuminate the photoluminescent material. Photoluminescence from the photoluminescent material backlights the light valve when the excitation light source illuminates the photoluminescent material.
