Hardware question: Photo-shy LCD
-
I have an odd problem (no, not that kind of odd problem :-O!) , and wondered if you guys had seen it, or know of a cure? We seem to have a photo-shy LCD screen on a piece of hardware that we're developing... has anyone here had any experiences with graphic LCD screens "crashing" when a flashgun, e.g. from a camera, is flashed close to them? If this a widely known phenomenon, and if so is there a simple cure please? Thanks, Sam W

"The engine is running smoothly, Captain, should I point our phasers to the LCD?." "See what you can do, Scotty. Spock?" "It appears to be a Dell Notebook, Captain. Equipped with a Warp drive." [impressive sound of Warp engine coming up to speed, oohs and ahhs as crew gazes in the direction of enemy ship] "Put it on visual, Chekov." "What do you think, Spock?"

It combines the power of C with the readability of PostScript. -- Jamie Zawinski

What do you mean by crashing? How do you bring it back up after a crash?

The display goes blank, and the display driver IC requires a reset pulse to bring it back to life. I'm wondering if anyone else has experienced hardware failures (of any type) caused by camera flashes? Sam W

Silly thought. Could it be the flashes EMP that's causing this? Most flash tubes are powered by a HV pulse.

Indeed- there'll be upwards of 500v flashing the xenon tube.

Just to make sure: you are not pointing the flash at the screen itself to get a good shot of the display? If that were the case you would get a far better photo without a flash. Just use a tripod and long exposure. Adam _____________________________________ Action without thought is not action Action without emotion is not life

Here's a thought: Try not using a flash, but add a bright lamp or something. "For all of our languages, we cannot communicate" - Christy Moore, Natives
