Zusammenfassung: | 1,202,263. Variable reflectivity matrix displays. WESTERN ELECTRIC CO. Inc. 21 Nov., 1967 [23 Nov., 1966], No. 52824/67. Heading G5C. [Also in Division H4] The elements of a matrix display are formed of materials whose reflectivity is sensitive to an electric field at the space charge layer of their surfaces. Such electroreflectance materials, see Division H4, are described. Fig. 7 shows an element 40 of electroreflectance material, a field being applied across it to electrode 41 and transparent electrode 43. Alternatively, the insulator 42 can be eliminated and a Schottky-space charge rectifier established at the surface of element 40. |
