i think mobile and pc manufacturers should reduce the magnitude of 0% screen brightness, it looks 100% at night

Try to use sunglasses 😎

I have to be careful on my phone. If I turn brightness down to 0, the backlight shuts off and I can't see shit.

@spongessuck same here on a Macbook.

The problem is voltage regulation: LEDs (in an LCD backlight, or in an AMOLED screen) have a weird voltage response curve so you need extremely precise with the control for low brightnesses, which requires expensive and bulky electronics.

(I think, I may just be talking out of my arse cos I'm no expert)
