SPECIFICATION TO ALL WHOM IT MAY CONCERN: BE IT KNOWN, that we, JOHN LEWIS GLASPER, Eastlea, Homend Crescent, Ledbury, Herefordshire, England; IAN ALEXANDER SHANKS, 56 The Bury, Pavenham, Bedford, England; and MICHAEL GEORGE CLARK, 27 Crown Lea Avenue, Malvern, Worcestershire, England, having made an invention entitled ELECTRONIC DISPLAYS, the following disclosure contains a correct and full description of the invention and of the best mode known to the inventor of taking advantage of the same: ABSTRACT OF THE DISCLOSURE A polar co-ordinate display of full 360° arc comprised of electrode bearing substrates each side of a layer of dyed phase change liquid crystal material. One set of electrodes comprises concentric spirals, the other set comprises radials. The display is multiplex addressed using four select waveform signals. These four signals V1, V2, V3, and Vx satisfy the following conditions:- RMS(Vx - Vi) = Vp, i = 1, 2 or 3; RMS(V1 - V2) = Vp; RMS(V1 - V3) = Vo where Vp is an upper threshold voltage, and Vo a saturation voltage for dyed phase change hysteresis, and may be of the coded form; V1 = , 1010,; V2 = ,1100,; V3 = ,0101,; Vx = ,0110,. These may be generated using two 2-bit registers with exclusive OR-gate feedback.
