  • the device arrangement comprises a signal evaluation circuit which, if the signals on the keyboard signal line do not change for a predetermined period of time, switches off the power supply to the tube monitor via a power supply interrupter switch.
  • the tube screen device thus also assumes a similar state to an energy-saving state.
  • the modules of the tube screen device are prematurely worn out due to increased on / off cycles due to the total shutdown of the power supply, thereby shortening the life of the device. So this is not a component-saving energy saving control. If the tube heating is also maintained, there is a risk of "cathode poisoning". 0
  • the object of the invention is therefore to provide an electrical functional unit and a tube screen device of the type mentioned at the outset, in which there is the possibility of the control device controlling an energy-saving state of the tube screen device which is gentle on the components by reducing power or switching off, without this the use of the individual devices is limited to an arrangement in which both the control device can control the energy-saving state of the tube screen device and the tube screen device can be controlled with respect to an energy-saving state.

In this case, the standard interface would have, for example, three line connections for each video signal of a given color.

It is advantageous, at least in this case, if the control unit PC has a device for switching off the function controlling the PSB decoder, which e.g. can be operated optionally by a user of the control device PC.

Abstract

La commande du fonctionnement en mode économique d'un écran cathodique (M) se fait par un appareil de commande (PC) qui lui est relié par l'intermédiaire d'une interface standard (SS) commandant le fonctionnement de l'écran, sans que les différents appareils soient limités à une utilisation dans une configuration avec des appareils accordés les uns avec les autres en vue de la commande du fonctionnement en mode économique. Entre l'appareil de commande et l'écran (PC et M) sont prévus des moyens permettant une transmission codée d'un message (PSB) qui commande le fonctionnement en mode économique de l'écran (M), ladite transmission étant indépendante de la fonction de l'interface standard (SS).
