What distinguishes this from IR is that it will be eliminated instantly upon displaying actual content and should not be visible with other solid color content, just black.
I wish there was a term for this (maybe there is, but I don't know of one) so we could call it something and distinguish it better from IR. I might suggest "black screen persistence" or something along those lines, since low APL content is required for it to be visible.
No, it seems like mild IR. My tv does it too, and it doesn't just go away the next time something is on the screen. It stays there for seconds or minutes during the displaying of other content depending on how long the IR image was there to begin with.
For example, on the ps3 xmb if I have Killzone 2 in the drive, and then go to the killzone disk icon so that the Killzone backsplash comes on the screen, the very bold white killzone title will remain on the screen after its gone even after it was up for only 5 seconds. If i get it, and watch 30 seconds of tv, then switch back to a black screen it is still there, only more faded. It will go away pretty quickly, but it forms very quickly too, and I would definately classify it as IR.

Phosphorescence is a sort of afterglow where you see the ghost images of previous content on the screen after you turn the TV off or switch to a blank-input/no-signal screen. All plasmas and tube TVs do this.
So is this a different phenomenon than IR, or is IR the same phenomenon of a different level?
