TIL: I was totally unaware that recent-ish LCD screens still suffer from (albeit temporary) image burn-in. Somehow I always thought my OS/WM/graphics card/driver has some seriously weird pixel buffer/compositing issues but today (when a boot selection screen burned itself onto the screen lol) it finally dawned on me that the problem might be a little more down to earth. :D

@freebliss any idea what happens? do the crystals somehow get stuck in a formation? :3

@cblgh nope no idea how this works unfortunately :) i'm under the impression this might be affected by temperature though - it's 30+ degrees (celsius) in my flat right now and even while writing the above toot the white form field for authoring the toot content slightly burned itself into the screen, which seems rather extreme, but now that I know this to be a hardware phenomenon it seems plausible to correlate it with heat at least (also given I only very occasionally notice this, possibly only in the summer as it occurs to me now :D). Also fullscreen colorcycling through min/max RGB states fixes it ( -> -> -> #000000 -> -> etc.) yaaayyy \o/ :)

@cblgh did some reading on it, according to wikipedia "The cause of this tendency is unclear. It might be due to accumulation of ionic impurities inside the LCD, electric charge building up near the electrodes, parasitic capacitance, or 'a DC voltage component that occurs unavoidably in some display pixels owing to anisotropy in the dielectric constant of the liquid crystal' " (ok cool. haha)

Also I really dig my mental image of crystals chilling out here :D -> "(...) turning off the monitor for a sufficiently long period of time (a few hours or maybe days) will relax the crystals and eliminate image retention."

@freebliss the lil crystal buddies just need to take a break some times ya know 💠

@freebliss The smartphone I've using the last few months (Xiaomi Note 7) has a bright screen with incredibly high pixel density and looks great overall, but it has SERIOUS burn-in issues...

@totoroot whoa interesting that this is also a thing on smartphones! I remember dumbphones having incredibly slow screen image transitions in extreme cold (half a minute even), somehow there's always something. :D
