In this invention a time-varying or a fixed-value quality is displayed on the two dimensional face of a new electro-optical cell. This cell can be utilised in flat panel displays which presently employ either one of the several types of Liquid Crystal cells operating in a variety of modes, or which employ Electroluminescent, Plasma Discharge, Electrochromic, Electrophoretic, Display Suspension, Fluorescence Activated or other cells well known in the art. Presently such cells consist basically of two parallel electrode structures deposited or attached to plates which form the walls confining an electro-optical compound. The distinctive feature of this invention which is applicable to all cells mentioned in the foregoing, is the non-parallel or slanted orientation of the two electrodes and of the plate surfaces on which they are deposited, with respect to each other. The resulting variation of the spacing between the electrodes across the cell varies the electric field and thus the distribution of lighted areas on the face of the cell. This distribution is also a function of the applied voltage to the electrodes and the voltage waveform. These effects can be used in simple forms of meters, indicators, monitors and in animated displays for advertising and signage, toys and games. |
