What does OLED black smearing look like? In this example, the dark grey square seems to be lagging behind the light grey square, but they’re locked together. (Needs to be viewed on an OLED screen.)

This is because changing pixels to and from pure black is slower than changing to and from other colours.

Developers and designers, please be careful when using pure black with animation and scrolling. 😀

@marcedwards I need to test this, but I wonder what’s the darkest color you can use before getting black smearing.

@kevin I’d love to know. I suspect it’s probably anything that’s non-black, assuming the hardware will keep power to the pixel for #010101.
