Touchscreen user shutdown

I have a client with two touchscreens, one in the kitchen and one above his bed.

He has asked me if it is possible to shut down the touchscreen of a night in the bedroom. He is worried about electrical fields and the like (he's a doctor).

Is there anything we can do?

if not, can we do anything to minimise the 'buzzing computer above my head'?

 

Black and White or Colour screens?

 

both colour

 

I guess you could power the unit via a C-Bus relay and control that relay from the other C-Touch. This is an undesirable thing to do though, because each time you switch one on, it takes a while to establish all of the C-Bus levels etc.

The Colour C-Touch has passed very stringent EMC tests. The electric fields emitted would be no more than from other sources - power wiring, clock radio etc.

I have never heard one "buzz". Does it really make a noise ?

You should set it up so that the backlight goes to its lowest level when the room is dark. You could also set up a time-out page which is essentially black with maybe a small clock on it in a light colour font. This will make it much less conspicuous at night. You could probably do this and tell your client that it is a low-power mode

 

No, they don't make a noise, but he is just VERY concerned about EMC and the illuminance of the screen.

Thanks for the input, I was thinking the same about the black page and backlight. Maybe future updates could have a hibernate option? dunno how successful that would be to do though
