摘要： A liquid crystal cell having a chamber for receiving a layer of liquid crystal material which chamber is defined by a pair of plate members joined together adjacent their edges by a substantially continuous glass solder seal characterized by the glass solder seal being provided in the form of one or more glass fibers which are interposed between the plates and fused to form the glass solder seal. To facilitate positioning the one or more glass solder fibers, positioning means are provided on one surface of one of the plates and may be protruberances which are formed either by crystallizing glass solder, or by laser bombardment of the one surface. To facilitate the obtaining of the desired spacing between the plates, each of the glass fibers may have a core which may be either hard glass or a metal such as gold which core is surrounded by a lower melting glass so that during fusion of the fiber, the core remains substantially unmelted. In another embodiment, the glass fibers contain a material, such as being impregnated with CuO, which will absorb infrared radiation so that during the method of forming the cell, the step of heating to fuse the fibers includes subjecting the fibers to infrared radiation after preheating the assembled plates and fibers.
摘要翻译：一种具有用于接收液晶材料层的室的液晶单元，该室由一对板构件限定，所述一对板构件通过基本上连续的玻璃焊料密封接合在其边缘附近，其特征在于所述玻璃焊料密封件以一个形式提供或更多的玻璃纤维，其插入在板之间并熔化以形成玻璃焊料密封。为了便于定位一个或多个玻璃焊料纤维，定位装置设置在一个板的一个表面上，并且可以是通过使玻璃焊料结晶或通过一个表面的激光轰击形成的突起。为了便于获得板之间的期望间隔，每个玻璃纤维可以具有芯，其可以是硬玻璃或金属，例如金，该芯由下熔融玻璃围绕，使得在纤维融合期间，核心基本上未熔化。在另一个实施方案中，玻璃纤维含有诸如被CuO浸渍的材料，其将吸收红外辐射，使得在形成电池的方法期间，加热熔化纤维的步骤包括在预热之后对纤维进行红外辐射组装板和纤维。

摘要： A liquid crystal cell for a liquid crystal display screen having a pair of plates joined together by a frame to form a chamber for a liquid crystal layer which is hermetically sealed from the exterior of the cell and has a closable access passage characterized by the access passage receiving a ductile metal plug of a metal which is selected from a group consisting of indium, tin, lead and aluminum and a sealing coating covering the plug and a portion of the exterior of the cell surrounding the passage. In one embodiment, the passage is a groove extending inward from an edge of one of the plates and has a depth which decreases as the distance from the edge increases so that it merges with the interior surface of the plate inward of the frame which may be formed with the recess facing the groove. In another embodiment, the passages are apertures having axes which are perpendicular to the plate and are arranged in a region of the plate adjacent to the frame means preferably with an aperture at opposite or diametric corners of the cell. In both embodiments, the sealing coating may be a synthetic adhesive or a portion of the exterior of the cell surrounding the passage or the aperture is metalized with a bright metal film with the metal being selected from a group consisting of silver, gold and platinum and the sealing coating is a layer of solder applied onto the metalized film.
摘要翻译：一种用于液晶显示屏的液晶单元，具有通过框架连接在一起的一对板，以形成用于液晶层的腔室，所述腔室与所述单元的外部气密密封，并具有封闭通路，其特征在于，所述通路通道接收从由铟，锡，铅和铝组成的组中选择的金属的延性金属塞，以及覆盖所述插塞的密封涂层和围绕所述通道的所述电池外部的一部分。在一个实施例中，通道是从一个板的边缘向内延伸的凹槽，并且具有随着距离边缘的距离增加而减小的深度，使得其与框架内部的内表面合并，该内部表面可能是形成有面向凹槽的凹部。在另一个实施例中，通道是具有垂直于板的轴的孔，并且布置在板的邻近框架装置的区域中，优选地在孔的相对或直径角处具有孔。在两个实施例中，密封涂层可以是合成粘合剂或围绕通道的单元的外部的一部分，或者孔用金属光泽金属化，金属选自银，金和铂，密封涂层是施加到金属化膜上的一层焊料。
