摘要： Electro-optic passive display cell constituted by a layer of a mixture of a nematic liquid crystal having a positive dielectric anisotropy, an optically active compound and dichroic molecules. The inner faces of the plates of the cell are covered with alignment layers such that, in the area situated outside the display zones or segments, the layer of the mixture has a homeotropic structure in its whole thickness. Opposite the segments the cell is arranged in such a way that the layer of the mixture has a helicoidal structure so that incident light is absorbed in these zones when the segments are not activated and that the layer of the mixture is orientated according to a homeotropic structure under the action of an electric field. Thus, when the cell is at rest, all its segments are visible. The display is effected by "cancelling" or "effacing" the segments which must not appear, so that only the non activated segments remaining visible in dark on a clear or transparent background.
摘要翻译：由具有正介电各向异性的向列型液晶的混合物层，光学活性化合物和二色性分子构成的电光无源显示单元。电池板的内表面被对准层覆盖，使得在位于显示区域或段之外的区域中，混合物层具有整体厚度的垂直结构。在该区段的相对侧，单元布置成使得混合物层具有螺旋结构，使得当区段未被活化时入射光被吸收在这些区域中，并且该混合物层根据垂直结构定向在电场的作用下。因此，当电池静止时，其所有部分都可见。显示是通过“取消”或“消除”不能出现的片段来实现的，使得只有未激活的片段在透明或透明背景下在黑暗中保持可见。

摘要： A liquid crystal alignment film is deposited on the inner surfaces of two plates of an electro-optic passive display cell. The film is vacuum evaporated on the plates at an incidence of 5.degree. and at least one plate is rubbed in only the direction of deposition. A helicoidal nematic liquid crystal is disposed between the two plates of the cell, and is aligned by the film.

摘要： An electro-optic passive display device displays information in dark characters on a light background during the day, and in light characters on a dark background during the night. The device has a polarizer, an electro-optic display cell, a quarter-wave plate, a chloesteric liquid crystal cell and an illuminator arranged in superposition on each other. These elements control the polarization of light transmitted through the device which polarization causes the changing of the displayed information from dark characters on a light background to light characters on a dark background.

摘要： An electronic timepiece provides photo-electric cells disposed behind a passive electro-optic display cell for recharging a storage battery. The timepiece includes in its display a polarizer, a passive electro-optic device such as a liquid crystal, a quarter-wave plate, a cholesteric liquid crystal reflector and photo-electric cell arranged in superposition upon each other. Ambient light passing through the cholesteric reflector is used to energize the photo-electric cells which recharge the storage battery. Ambient light reflected by the cholesteric reflector is used to indicate the displayed information.

摘要： A universal timepiece (10) having a manually operable outer ring (33) for selecting one of twenty-four time zones, where a display indicates the time of the time zone selected. For this purpose a device for detecting the rotational position of the outer ring (33) is provided which has a special arrangement of permanent magnets (39a-j) in the outer ring (33) and of magnetic switches (27a-h) in the timepiece casing (11, 12) in a specific number as well as evaluating electronics in the timepiece movement (21). The permanent magnets (39a-j) determine the binary statuses of the magnetic switches (27a-h), which are interpreted together as a signal or as a status pattern. The special arrangement of the magnetic switches (27a-h) and the permanent magnets (39a-j) effect for each rotational position an intrinsic status pattern different in each case from the others which permits a clear indication of the selected rotational position of the outer ring (33).

摘要： An electro-optic display device having a partially transparent display cell and a semi-transparent mirror located behind said cell and arranged to transmit light waves within a first wave length band and to reflect light waves within a second wave length band. An electro-optic component is located behind the semi-transparent mirror and operates in a third wave length band which overlaps at least partially the first wave length band. The electro-optical component may be a plurality of photo cells used for recharging an accumulator for the display device and/or a light source transmitted across a light plate of frosted or clear glass to illuminate the display cell. The display cell is illuminated by either the reflected light waves or the light waves emitted from the light source.
