13. A light source, comprising:
-
an electroluminescent panel having a light generating layer; and
a birefringent reflective polarizer positioned to receive the light generated by the light generating layer, wherein the reflective polarizer transmits light of a first polarization and reflects light of a second polarization back to the light generating layer, and wherein the light generating layer diffusely reflects and randomizes the polarization state of the reflected light and recirculates the reflected light back to the reflective polarizer. - View Dependent Claims (15)
