A polarizer-free flexible display using dye-doped liquid-crystal gels

Abstract

A reflective-type polarizer-free flexible display using a dye-doped liquid-crystal (LC) gels is demonstrated. Compared to the conventional guest-host LC mode, it has high contrast ratio and brightness due to the combining of both scattering and absorption. Such a gel-like flexible display is bendable and trimable. In this paper, a three-step switch using distinct dye-doped LC gels is also demonstrated. The potential applications are e-paper and decorative displays.
