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： The liquid crystal switchable color filter switches between three color bands and is preferably used for time-sequential color devices, as for example projection devices, direct view displays and video cameras. The color filter employs circularly polarizing selective reflection bands of at least four cholesteric filters (89, 91, 93, 95) together with three liquid crystal switches (81, 83, 85) and related retarder layers. Between the first and the second as well as between the third and the fourth cholesteric filter an additional half-wave plate (111, 113) is provided, which makes it possible to use cholesteric filters having all the same handedness. Furthermore, for the blocking state of a color band the optic axis of the corresponding liquid crystal switch is parallel or perpendicular to the polarization direction. This concept simplifies production and still exhibits excellent properties for the color switch. Moreover, it advantageously allows overlapping color transmission bands thus improving the light efficiency.
摘要翻译：液晶可切换彩色滤光片在三个色带之间切换，并且优选用于时序彩色装置，例如投影装置，直视图和摄像机。滤色器与三个液晶开关（81,83,85）和相关的延迟器层一起使用至少四个胆甾醇滤光器（89,91,93,95）的圆偏振选择反射带。在第一和第二之间以及在第三和第四胆甾醇型滤光器之间，提供了附加的半波片（111,113），这使得可以使用具有相同的手感度的胆甾型滤光器。此外，对于色带的阻挡状态，相应液晶开关的光轴平行或垂直于偏振方向。该概念简化了生产，并且对于颜色开关仍然表现出优异的性能。此外，其有利地允许重叠的彩色传输频带，从而提高光效率。

摘要： A liquid crystal display (LCD) panel employs a cholesteric polarizer which passes light of a first circular polarization, but reflects light of a second circular polarization. The LCD panel may be monochrome or color; in the color embodiments, several different color filters are used, each having one or more cholesteric polarizers tuned to a specific bandwidth in the visible spectrum. These polarizers replace dyed (neutral or dichroic) polarizers of prior art LCD panels, and provide improved color purity. The invention may be enhanced by providing a light recycling scheme whereby the handedness of the circularly polarized light reflected by the polarizers is changed and redirected back to the polarizers. This recycling scheme may also be adapted to provide an overhead projector having a high output polarized light source, particularly useful in conjunction with an LCD panel.
摘要翻译：液晶显示器（LCD）面板采用通过第一圆偏振光，但反射第二圆偏振光的胆甾型偏振器。 LCD面板可能是单色或彩色; 在颜色实施例中，使用几种不同的滤色器，每种滤色器具有调谐到可见光谱中的特定带宽的一个或多个胆甾型偏振器。这些偏振器代替现有技术的LCD面板的染色（中性色或二向色）偏振片，并提供改善的色纯度。本发明可以通过提供一种光循环方案来增强，由此偏振器反射的圆偏振光的旋转性被改变并被重定向回到偏振器。该回收方案还可以适于提供具有高输出偏振光源的高架投影仪，其特别适用于LCD面板。

摘要： The invention relates to an electro-optical cell (1) comprising a first (2) and a second (3) support member, an electro-optical medium (5) between the support members and an electrode arrangement (11, 12) on the support members such that an electric field can be applied, in the electro-optical medium, perpendicular to the support members, aligned with the support members or at an oblique angle (7) with respect to the support members. The electro-optical cell further comprises layers (14) of material with different dielectric constant between the support members in order to reduce the inhomogeneity of the electric field lines in the electro-optical medium. By having a layer of cholesteric liquid crystals between the support members, the electro-optical cell will function as a colour filter for varying applied fields. By introducing a particle suspension in a medium between the support members, an electro-optical cell is created that can be switched between a transmissive, reflective and partly deflective state.
