A DEMONSTRATION was given in London recently of the projection of received television pictures on to a screen measuring 4 ft. by 3 ft., a size which is intermediate between the conventional direct-viewing home receiver using a cathode ray tube from 9 in diameter upwards, and the full-size public cinema screen. The demonstration was arranged by Messrs Philips Electrical, Ltd., and indicated the commercial possibilities of a television prjection set giving pictures comparable with those obtained with a good-quality 16-rnm. cinema projector. It is estimated that some seventy people can view the picture in comfort.
