Whats going on with my PSP screen???

So i took my psp out of its case today to play it and I noticed this sort of faint bruise like spot on the screen, its really only noticeable on a white background. I'm very careful with it and always keep it in its case, I have never dropped it and i don't remember bumping it recently. Anyone know what this is or how to fix it?

I've never seen that before. Cleaning it is a good idea, though. If cleaning the front doesn't help, take off the faceplate. Clean the back of that and, very gently, the LCD screen itself.

I haven't got a clue. Maybe it's moisture related? IDK.

I opened it, its not dirt or moisture its like the lcd is dim in that spot

Hmm not sure if im just getting used to it or its going away, now its only faintly noticable on bright white screens. I did open it up and gently massage the area on the lcd screen while wearing powderless surgical gloves. Not sure if this is why its less noticable
