摘要： A display material and method and device thereof are provided. The display material is first formed by evenly mixing appropriate weight ratios of DFLCs, incurable nanoparticles, curable nanoparticles, and a photoinitiator. Next, the evenly mixed mixture is disposed between two parallel conducting transparent substrates, wherein an electrical field is conducted thereto and the DFLCs therein aligned to the direction of the applied electrical field. Concurrently, under the applied electrical field, some curable nanoparticles within the evenly mixed mixture, form short nano chains, initiating the photo initiator. The frame structure of short nano chains stabilize both the clear and scattering states, thereby the bistable characteristic was improved and the contrast ratio was enhanced as applied to bistable displays.

摘要： A light source module for generating polarized light includes a light emitting element, a reflector, and an optical element. The light emitting element generates a light ray, and the reflector reflects the light ray towards the optical element. The optical element includes a light splitting face and a reflection face. The light splitting face receives the light ray, and an angle between the light splitting face and the incident light ray is at about a Brewster's Angle. After the light ray is irradiated to the light splitting face, the light ray is divided into a refraction light and a reflection light. The reflection face reflects the refraction light, and the reflection face is substantially perpendicular to a path of the refraction light. Therefore, a light source with a high degree of polarization is realized by a design of the light splitting face and the reflection face.
