Paper Abstract

The liquid crystal display industry relies on low cost high performance polarizers. In this paper we will describe a novel reflective polarizer, based on a special cholesteric liquid crystal (CLC) blend which results in a single layer polarizer having a super broad band approaching 2,000 nm. The novel polarizer overcomes many of the limitations of the conventional dichroic polarizers. It also improves the band width of prior art CLC polarizer invented by Phillips. While the latter relies on creating a linear pitch gradient and requires a special UV dye to obtain the broadband polarizer. Reveo's invention, in contrast, eliminates the need for special UV dye and uses a non-linear pitch distribution to create a band pass of about 2,000 nm in a film thickness of 20 microns.
