Abstract
A method of manufacturing an electro-optical cell in which at least one insulating lamina of adhesive material bonded to at least one spacer element and having an opening defining the limits of the cell is introduced between two cell walls, and the walls are then heated and compressed to soften the adhesive material and seal the cell. The cell may have a spacer element in the form of a lamina of plastics material or may have a number of metallic spacer elements which provide electrical connections to conductive elements carried on a wall of the cell.
Claims8
A method of manufacturing an electro-optical cell having parallel spaced-apart walls wherein at least one spacing element bonded to at least one insulating lamina, of an adhesive material which may readily be softened, is introduced between two cell walls and the at least one lamina is then softened to seal the cell walls and to cause the cell wall spacing to be determined substantially by the thickness of the spacer element or elements.
