| Abstract: | A novel arrangement of colour-capable multi-legend displays is described. The electrodes are patterned to carry a continuous fixed message in positive or negative contrast. Colour is obtained either by dyes in guest-host type liquid crystal displays or by using a combination with thin film electroluminescent backlights. The main advantage is in its use in the future for keyboards where the keys can be used in a touch-sensitive interactive display mode. |
