    • 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.
    • 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。
