Abstract

578,423. Colour television receivers. SCOPHONY, Ltd., and WIKKENHAUSER, G. May 1, 1944, No. 8178. Drawings to Specification. [Class 40 (iii)] A colour television receiver comprises a cathode-ray tube in which the opacity of the screen is varied by picture signals and the received image is formed on a viewing screen by focusing light transmitted through the tube screen, with or without reflection, as described in Specification 513,776, the light forming the image being coloured before reaching the viewing screen by a colour wheel or the like or by employing alternate differently coloured sources. This arrangement avoids the necessity of using a large colour wheel at the receiver, as the colouring may be effected at or close to the light source or near the objective where the beam is constricted. Specification 514,776 also is referred to.
