Method of making an electro-optical display

摘要

Disclosed is a method of making an electro-optical display and the display made by such method having improved optical uniformity provided by the use of one or two pressure plates having raised portions that are dimensionally adapted to press uniformly on the seal enclosing the electro-optical material in a cavity between two plates of the display or uniformly upon the seal and at least one support member disposed in the cavity as a means of providing support and improving parallelism between the plates. The method also includes embodiments of electro-optical displays in which the support members, if used in the display, comprise a plurality of graphically shaped support members that not only provide support and improve parallelism between the plates but which are also able to convey information to a viewer of the display regardless of whether the electro-optical material is in an electrically energized or an electrically unenergized state.
