Will direct sunlight damage my screen ?

I have a South facing lounge and I have noticed that during part of the day sunlight is shining direct onto my Panasonic PW7 screen. At this time of year I guess that it is not going to get too hot (!!), but in the summer it will be on it for longer and be much hotter. What is the screen made of (it almost seems like a toughened plastic/very thin glass) and will extended periods of direct sunlight warp it, or cause some other sort of damage ?

I cannot find out anything about it in the manual and the missus will not be very happy if we have to keep the curtains or nets closed all the time...

Of course this could just be a very, very stupid question and I apologise if it is. - I am half expecting loads of these:-

Cheers,

 

It's an interesting question, but I doubt if sunlight would make it get as hot as when it's in use...
