Abstract
An electro-optic passive display cell including two glass plates positioned spaced from each other with the edges thereof sealed and having an active constituent disposed between said plates. The plates are maintained in spaced and sealed relationship by a frame-shaped distance-piece adhered to the plates by a layer of glass paste solidified by sintering. The cell is formed by applying a high frequency induction current to fuse the frame-shaped piece to at least one plate.
Claims7
A method of manufacturing an electro-optic display cell, the cell including a first plate and a second plate arranged spaced parallel one another, a frame interposed between the plates and spacing the plates apart to form a space therebetween, and an electro-optic display material contained in the space between the plates and frame, the frame including an annular part of thermo-fusible material and a metallic annular element in contact with said thermo-fusible material part, the method comprising:
- welding the frame to the first plate by heating the frame and first plate to fuse the thermo-fusible material between the frame and first plate;
- filling the space between the plates and frame with the electro-optic display material;
- and
- welding the second plate to the frame by heating the metallic member with an induced high frequency current to fuse the thermo-fusible material between the frame and the second plate.
