BILDWIEDERGABEANORDNUNG MIT EINER BILDROEHRE UND VERFAHREN ZUR HERSTELLUNG.

摘要

The display screen comprises an image tube with a polarisation foil applied to its front face. A liquid crystal cell with opposing sets of transparent control electrodes is sandwiched between the outer surface of the screen front face and the applied polarisation foil. The liquid crystal cell and the polarisation foil are both applied directly to the front face of the screen via a transparent adhesive with a refractive index between the refractive indices of the boundary surfaces on either side of it. Pref. the liquid crystal cell comprises a polymer liquid crystal foil incorporating a ferroelectric liq. crystal material.
