A prototype of a color TV monitor

This is a prototype of a color TV monitor, which was inherited from a famous Czech pioneer of television technology, Ing. Vladimír Vít. We do not know any details about the origin and the design of this monitor, but it is clear that it comes from the same era as the color TV camera prototype and these two devices were probably operated next to each other. We do not even know whether the monitor is equipped with a color signal decoder, but it is likely that the RGB color component signals were connected straight from the camera without any encoding. The most delicate part of a color TV or monitor is the picture tube, whose manufacture is very complicated. This prototype contains a U. S. picture tube. Later, Soviet picture tubes were used in Czechoslovak color TVs and monitors, but these were of rather poor quality. In the 1980s, Tesla Rožnov started to produce color picture tubes of Japanese license, which finally offered a perfect color image.
