Any lcd screen...... I was playing with my front facing camera on my phone with my green laser taking pictures and I guess it got too close and I burned out like 4 pixels it's really small but I still know that is what did it but I don't have my laser lpm'ed .... so its over 100??? Over 60. ????? I'm going to get it lpm butt was just wondering and thought it was kinda instresting for other people to know the answer........

There is no specific point at which pixels start dying... it would vary from screen to screen.

Laser Safety 101:

DON'T POINT LASER AT STUFF YOU DON'T WANT DAMAGED...

Kind of thought that was a given:p
 
I thought about camera pixels. I guess 5mW lasers would be fine, as I guess the cameras (and screens) are less sensitive to damage then the eye.
But 50mW can cut plastic tape if focused well .. so I guess it can damage screen pixels. Ans camera pixels could be even more sensitive. Still I shone 200mW on my webcam and it did no damage at all. On the other hand I know cameras are often damaged on laser shows.
 
Are you sure your phone has a LCD screen? Quite a few have OLED these days.
Both can be damaged but its much easier with OLED.

<5mw likely to survive temporary exposures

if you want to destroy some cameras, you get just buy cheapy ones for $10
 
I did not mean to do it but whatever its under warranty...

I was just running it across my screen Not into the camera. But I guess we all learn the hard way sometimes lol
 
maybe a little unrelated...
Here are some yellow spots I accidentally burned on my laptop's screen over a year ago, it was with a ~200mw LOC, it burned them instantly.

Wow .. nice ! Instantly you said ? Would it be possible to paint a picture on the screen ? Somebody else's screen of course .. like your boss .. for example something really rude ..
Just thinking .. :umbrella:

Pretty much that, LCD grafitti anyone? :D
 
Nice. I burned my LCD in quite a few places with my 200mw red, was quite instant actually. I really wasn't expecting it lol, I'm just glad it didn't burn right through it and cause it to bleed :(
 
polarizing filters absorb quite a bit of radiation. They are also made of a not-so-heat-resistant material. Without polarization, no way to filter out an "on" pixel from an "off" one, so you just get a white spot.

BTW, diffraction gratings sometimes, and nice smooth matte films for flashlights and stuff.
