Abstract

Disposiciones reproductoras de imágenes de televisión que comprenden una fuente de electrones modulados de acuerdo con señales de televisión recibidas, caracterizadas por el hecho de que una primera superficie capaz de emitir un rayo de luz ultra-violeta en respuesta al bombardeo electrónico está dispuesta en la trayectoria del haz electrónico, y de que una segunda superficie revestida de un material capaz de generar luz visible al excitarse con luz ultra-violeta es capaz de ser dispuesta en la trayectoria del referido rayo de luz ultra-violeta, estando adaptada además esta última superficie para dirigir la luz visible generada por ella, en dirección a un observador.Television image reproducing arrangements comprising a source of modulated electrons in accordance with received television signals, characterized in that a first surface capable of emitting a ray of ultra-violet light in response to electronic bombardment is arranged in the path electron beam, and that a second surface coated with a material capable of generating visible light when excited with ultra-violet light is capable of being arranged in the path of said ultra-violet light ray, the latter surface being also adapted to directing the visible light generated by it, in the direction of an observer.
