摘要： The present invention is directed to a process and display for producing an image in front of an optically contrasting background. The display installation is characterized by a preferably but not necessarily, plate-shaped body having exit windows for emitting light in given areas and light valves associated with each of the exit windows for controlling the light being emitted therefrom. The light valves include filters which have an absorption frequency range and the plate member emits light from the exit windows in an emission frequency range. One of the members, either the filter member or the plate member, can have its associated frequency range shifted by the application of an electrical field so that light can pass through the filter without being absorbed or is absorbed by the filter.

摘要： An indicating device having an electro-optical light valve unit such as in a liquid crystal cell arranged behind a plate containing fluorescent particles characterized by a contrast filter disposed behind the plate and unit in the direction of viewing and a reflector disposed behind the contrast filter. The contrast filter will pass light of the spectrum which excites the fluorescent particles of the fluorescent plate but absorbs the emitted fluorescent light and a majority of the other light so that a background is either dark or of a specific color. The energized light valves cause a bright image on the dark or colored background.

摘要： A display device for representation of a bright image on a background which device has a light valve comprising a liquid crystal cell having a medium which can be switched zone-wise between at least two optical states and a light trap or body which consists of a material having an index of refraction greater than 1, contains a fluorescent material, and is provided with an outlet window for each of the switchable zones characterized by means coacting with the switchable medium to control the passage of the light through the device so that in a rest or inactive state of the medium, the medium and means allow the passage of the excitation light for the fluorescent particles and the passage of the fluorescent light therefrom and in an "on" or activated state of the medium, the means and medium are impermeable at least to the fluorescent light so that each of the switchable zones of the medium is placed in an "on" state only when it belongs to the background of the image. The means may be a pleochroic dye operating with a single polarizer or a pair of cross polarizers, which cooperate with the material of the liquid crystal which forms a twisted cell.

摘要： A liquid crystal cell comprising at least two plate members each having a surface with at least a portion thereof having electric conductive coatings thereon and spacing means for maintaining the plate members with said surfaces parallel to one another to enclose a liquid crystal layer characterized by the spacing means consisting of at least one glass fiber which is imperviously connected to the plates by an adhesive. Preferably, the glass fiber is provided with an adhesive coating so that during assembly of the parts forming the cell, heat and pressures will cause the adhesive coating to be extruded from between the fiber and the surfaces of the plate member to enable the fiber to come into contact and to adhesively bond the fiber to the surfaces of the two plate members.
