摘要: A diffuse reflector (100) uses a host layer (120) containing particles (122). The host layer (120) contains a cholesteric material that reflects a first frequency of light, and the particles (122) in the host layer (120) create separate cholesteric domains (126) that reflect light of the first frequency in different directions.

摘要: A reflective display device includes a pixel structure (200) and a liquid crystal (210) containing a dye. The pixel structure (200) provides the liquid crystal (210) with a first tilt state and a second tilt state that are stable absent application of an electric field. In the first tilt state, the liquid crystal (210) is in an untwisted configuration. In the second tilt state, the liquid crystal (210) is in a twisted configuration, and the dye has an effective absorption that is higher than an effective absorption of the dye when the liquid crystal (210) is in the first tilt state.
