Ooops yeah. Sorry. I guess that's what I get for skimming LOL.
You would be surprised how many people do that to my posts
Everything that's ever been said about OLED displays is that when it's displaying black the pixel is off. So yes, it does have local dimming. Pixel perfect local dimming. What I'm thinking is that maybe the source isn't a "true" black and it's confusing the device, causing some of the pixels to display a "near black". Does that make sense at all?
Yes that makes sense actually, like pixel noise in a picture taken of something that is in reality uniform color, like if you take a picture of complete blackness and you get random flecks of distorted colors that are "near-blacks." So I guess the backlight is turning off in the places the image is trying to display truly black and just getting close elsewhere? It is odd since it should be truly black in a native (loading / booting) screen, but then again it could be hardware based in the pixel grid or just bad approximation - or even stranger: some type of 3D "pixel terrain" that could be modeled on a tri-axis which explains why the dark spots occur where they do due to some fault or limitation of the logic control in the display.
Electronics have minds of their own sometimes and it is fascinating.
