摘要： A polarization light splitting film (10) having a light receiving side and a light transmitting side. The polarization light splitting film includes an optical rotation selection layer at the light receiving side for reflecting one of right and left circularly polarized components of a light beam that is incident on the light receiving side and for transmitting the other one of the right and left circular polarization components of the light beam, and a quarter-wave layer (2) laminated over the optical rotation selection layer at the light transmitting side. The light splitting film comprises further a diffusion layer (5) and a prism layer (6).

摘要： The present invention provides a polarizing colored light source for a display system in which light of other polarization states and colors are recyled. The color can be scrolled synchronously with a display. In one embodiment, the invention includes a tunnel (21) having an entrance aperture (19) facing a lamp (11) to receive light having multiple polarization states from the lamp and direct the light from the lamp to an exit aperture (23) opposite the entrance aperture (19), the tunnel having a reflective face (29) about the entrance aperture to reflect light within the tunnel toward the exit aperture, a reflective polarizer (25) to reflect light of one polarization state toward the entrance aperture and transmit light of another polarization state, and a color reflector (25) to transmit light within one color range and reflect light of another color range toward the entrance aperture.

摘要： A liquid display, wherein a printed layer having an opening in the portion thereof which is on the opposite side of an observer of the liquid display, the displaying being done by utilizing the absorption or chromaticity of the printed layer when an external light source is utilized, by passing the light through the printed layer via the opening thereof when an auxiliary light source is turned on, and by applying different voltages to a liquid crystal layer by a gradation inversion circuit when the external light source and auxiliary light source are utilized, the inversion of brightness and darkness of what is displayed by using the external and auxiliary light sources being eliminated by a deflecting plate or a cholesteric liquid crystal polymer film provided on a rear surface of the liquid crystal display, whereby a liquid crystal display of a high visibility can be obtained.

摘要： Display apparatuses (100;200;400;500;1400) are shown capable of displaying information in a reflective mode using only ambient light (110;210;510) and in a transmissive mode using a light source (105;205;505;1405). In one embodiment, the display apparatus (100;1400) includes a reflecting polarizer (104;1408) disposed between a light modulating layer (102;1402) and an isotropic light cavity (105,106;1405,1406). The light cavity (105;106;1405;1406) reflects incident light with a first degree of depolarization. The reflecting polarizer (104;1408) reflects light with a second degree of depolarization for at least one polarization that is greater than the first degree of depolarization. In another embodiment of the display apparatus (200;1400), a microstructured film (204;1404) is included above a light cavity (205,206;1405,1406) and below a light modulating system (201,202,203,208,1401,1402,1403,1415) where the microstructured film (204;1404) includes sawtooth formations (207;1407) having at least a tilted surface (211,212;1411,1412). In another embodiment of a dual-mode display device (500), the display (500) includes a cholesteric reflecting polarizer (504) disposed between a light modulating layer (502) and a light cavity (505,506) where the light cavity (505,506) causes a polarization phase shift upon reflectance.

摘要： A colour switch for selectively switching between colour bands for use in projection optics and in direct view optics has fewer and thinner layers than in the prior art, but exhibits equal or better colour purity and light efficiency. The filter has a first filter section (2-8) for selectively blocking green light and including a cholesteric filter (2), a quarter wave plate (4) and a liquid crystal switch (6). The filter has a second filter section (10-22) for selectively blocking blue and/or red light including a stack of retarder elements (10, 14, 16, 20) and liquid crystal switches (12, 18), preferably DHF switches. The parameters of the filter are determined by an optimisation process including minimising a cost function G with respect to the parameters of the second filter section. Polarising element (8) may be positioned in front of the stack, and of a type which does not absorb radiation.
