A new technology for ultrathin dichroic polarizers that uses photo‐alignment technology has been introduced. This cutting‐edge polarizer boasts a record‐breaking dichroic ratio of over 150 in the blue band and is ultra‐ thin, with a submicron‐level thickness. These features make it a perfect fit for use in liquid‐crystal cell fabrication, as well as in ultrathin, flexible devices, and in‐cell applications. When combined with photoluminescent color filters, this polarizer can create advanced color conversion LCDs with no parallax, high efficiency, wide viewing angles, and a wide color gamut.
