On the BlackBerry section of the HowardForums mobile phone site, Forums Member BriBri99 started a thread with a common concern of those of us who remember computing wa-a-a-a-y back when. BriBri named the thread, Will my 7290 screen burn in?

"Might be a very stupid question," BriBri writes, but I know that there is a constant picture in the background, will this cause burn in?"

Well, BriBri, there are no stupid questions, just stupid answers.

And neither answer filed by subsequent HowardForums posters is stupid. In fact, the reply posts are helpful.

"LCD (Liquid Crystal Display) doesn't suffer from burn in," writes BlackBerry 7280 user Pennywise.  "In fact, I don't think that exists on anything newer than the a 1980's CRT

"I've never had it happen on an LCD," BlackBerry 7250 user jase88 writes. "If (the thought of burn-in) concerns you, use an OEM (Original Equipment Manufacturer) holster--the Blackberry screen turns off while in these holsters."
