Liquid crystal displays represent the dominant flat panel display technology, despite their limitations in brightness and efficiency originating from the use of absorbing polarizers and color filters. This paper reviews novel concepts of photoluminescent liquid crystal displays that employ photoluminescent polarizers. These polarizers exhibit highly anisotropic absorption and / or emission and efficiently combine two separate features: the polarization of light and the generation of bright color. A new photophysical effect - polarizing energy transfer - can be used to drive the efficiency of these elements to the theoretical limit: it enables to produce photoluminescent polarizers which optimally harvest incident light by isotropic absorption but emit the absorbed energy in highly linearly polarized fashion. Experiments suggest that the novel concepts can simplify device design and substantially increase device brightness, contrast, and efficiency.
