Abstract: The present invention provides for improved contrast in the transmissive mode of a transfiective liquid crystal display having a rear stack polarizing means (302) which is transmissive for light having a desired polarization and reflective for light having an opposite, undesired polarization. The contrast is improved due to enhancements of the black state provided by the inclusion of a reflection preventing means (306). The reflection preventing means is arranged between the transflector (301) and the rear stack polarizer (302), and serves to stop light transmitted through the rear stack polarizer (302) towards the transflector (301) from being reflected by the transflector (301) back to the rear polarizer (302). Thereby undesired reflections having wrong polarization are stopped from being transmitted through the transflector (301) and thus from affecting the transmissive mode black state of the display.

Abstract: Rewritable signs (100, 1300) that include bistable cholesteric liquid crystal layers (102, 1402, 1404, 1406) are provided. According to one embodiment a rewritable sign (100) is devoid of circuitry for establishing electric fields in localize regions for writing information to the rewritable sign (100), and is consequently inexpensive. In the latter embodiment, a separate information writer (400) that includes an array of pixel electrodes (404) that is driven by an active matrix (602) is used to write information on the rewritable sign. According to another embodiment a rewritable sign (1300) includes three cholesteric liquid layers (1402, 1404, 1406) each of which reflects a different primary color. The three cholesteric liquid crystal layers (1402, 1404, 1406) are interleaved with sets of conductive lines (1316, 1320, 1322, 1324) that are used to apply signals to the cholesteric liquid crystal layers (1402, 1404, 1406) for the purpose of writing information.

Abstract: A reflective type liquid crystal optically addressed spatial light modulator has a first transparent substrate(1b), a first transparent electrode (2b) formed on the first transparent substrate (1b), and a photosensitive layer (3) formed on the first transparent electrode, formed from materials including hydrogenated amorphous silicon carbide (a-Si:C:H). A read-out light-blocking layer (4) is formed on top of the photosensor layer (3) and is formed from amorphous hydrogenated carbon (a-C:H). The high reflectance dielectric multilayer mirror (5) is formed on top of the light-blocking layer (4) and can be made of alternating the a-Si:C:H layers with a higher refractive index and the a-C:H layers with lower reflective index. The modulator also has a second transparent substrate (1a), a second transparent electrode (2a) formed on the second transparent substrate (1a), and a liquid crystal layer (8) disposed between the dielectric mirror (5) and the second transparent electrode (2a). The invention allows more efficient separation of the input and read lights and increases the read light reflection, resulting in improvements to the input sensitivity, resolution, contrast ratio, and diffraction efficacy.
