Reply To: PS1 CD player screen burned into OSSC?

[Zod]

There is a warning in the official wiki, although it does not specify ‘in particular IPS panel displays’ which I think it should.

Beware of using the OSSCs Line2x (bob) or Line4x (bob) deinterlacing modes on sources that display static graphics or text for a long period of time. The OSSCs deinterlacer produces a constant flickering effect. This can cause image retention/burn in to occur faster than normal.

Once, after experiencing the same thing with the OSSC on an IPS, I wanted to try clean-scaled and unfiltered emulated games that feature flickering contents, like the title screen of Progear, and the burn triggered rather soon and was brutal, well-defined, kinda in the same fashion.

methinks, what participates;
a. sharper, unsmoothed scaling = fully exposed, less diffuse flickering (flicker more precisely localized on specific pixels where it happens)
b. purer colors to switch to back and forth = greater strain on the crystals
a+b = greater than usual flicker intensity that exhausts wimpy IPS crystals too soon

In short; manufacturers surely always knew about the limits but never thought anyone would try their panels with such ‘brutal’ signals lol.
