Abstract
909,748. Television. DESURMONT, R. July 25, 1960, No. 25879/60. Class 40 (3). [Also in Group XX] The picture reproduced by a television tube 2 (Fig. 1) is viewed by reflection at the surface of a polished plate 3 of transparent or opaque synthetic resin which may be tinted with a colour such as black or green. The plate 3 absorbs some of the picture light and this is stated to result in a picture of more acceptable contrast and to be substantially free from flicker. The reversal of the picture caused by reflection may be corrected by reversing the scanning direction of the tube beam. Alternatively, correction may be effected by producing a double reflection by means of an intermediate mirror 4 (Fig. 2) which together with the plate 3 may be carried by an independent support as shown in Fig. 3.
