Buring an image to any (?) LCD panel

[toomas]

So, today I was manually measuring my trusty 24" Dell U2412 LCD refresh rate, because it was reported 60Hz here and 59Hz there (turned out to be 59.9Hz) by running a program that switched a region on screen from black to white after every vsync. After a few minutes of epilepsy hazard while keeping a small solar panel towards the screen which was directly attached to a frequency counter I noticed that the flicker doesn't go away. It stayed there for hours. Removing power, doing factory reset, running lcd conditioning program built into monitor didn't help. Fortunately it just went away later

What is this? In one Dave's video his android phone started flickering the same way after configuring some internet of things thing in sd card form factor. I wonder if that is something that LCD displays just do.

If you don't believe it, here are instructions on how to burn a bunny image into your LCD panel

DISCLAIMER. IT MAT DAMAGE YOUR LCD PERMANENTLY, YOU DO IT ON YOUR OWN RISK.

• Open this gif https://dl.dropboxusercontent.com/u/47078707/epilepsy_bunny.gif
• Let it flicker somewhere on your screen for 5min or so, but don't look or you'll think it's your eyes playing tricks on you later. In my case the other parts of the screen were black, idk if that's necessary
• Scratch you head and worry if your LCD will ever be usable again
• (if you don't see it, turn contrast and brightness down to 50% or so)
