No doubt colour television will eventually supersede black-and-white transmissions. But there are other revolutionary developments to come, such as the “flat” screen - it will replace the conventional receiver box with its cathode-ray tube. The first screen, which can be hung on the wall like a picture, may be no more than 2 to 3 inches thick. It has a fluorescent coating like conventional tubes, but the electrons from the cathode move almost parallel with it instead of striking it at a right angle. They start their journey from an electronic “gun” at the top behind the screen, shooting downwards; at the bottom they are reflected by a “reversing lens” to travel vertically upwards along the screen, which they eventually hit by the influence of a grid of conductors which accumulate electric charges from the electron beam and give them off to the screen. The flat screen will be especially suitable for colour reception.
