recently bought a pana pv80, but ive been reading this topic before ko pa binili.
During my first try of the unit i already notice this problem. pag black un background and me reflection from the wdo, me parang criss-cross pattern nga.
Has anybody explained this issue yet?
I can't answer it with accuracy because I haven't seen it yet. My Viera is an old model, and it definitely does not have the crosshatch pattern issue.
Panasonic has no official statement on the matter yet. But I did find some foreign user posts that give a reasonable explanation:
The crosshatch pattern is normal. It is a side-effect of the screen's anti-reflective coating.
The anti-reflective coating is supposed to reduce glare when there is a bright light in the room that shines on the screen. The coating does reduce glare, but the side-effect is a faint crosshatch pattern. Therefore, the anti-reflective coating is not very useful.
If your screen has an anti-reflective coating:
1. If there is an external bright light, glare is reduced, but there is a crosshatch pattern.
2. If there is no external bright light, there is no crosshatch pattern; but then, the anti-reflective coating would not have been necessary.
