I thought that with OLED screens, and a dark mode that supports it, black pixels are actually not backlit, meaning they use less energy. Is that not right?
Using dark mode might be more energy-intensive if the screen is an LCD.

Right, OP refers to LCD, which is the older tech that works by selective occlusion.

Ah. Thanks for pointing that out, @Septimaeus@infosec.pub. I was considering an OLED screen to be a modern LCD screen.

I use dark mode to save my eyes, not energy.
Interestingly though I haven’t had OLED display on any of my devices since 2013.

Do you mean LCD?
Perspectivist@feddit.uk 1 month ago
No, OLED. Samsung Galaxy Note 3 is the device in question.

That’s why I don’t use LCD if I can help it nowadays

Energy usage is the reason? I hope you understand how negligible it is…
Malfeasant@lemmy.world 1 month ago
It’s not negligible when running on battery…

This does not make sense, explain.

LCDs work by using energy to block the backlight strategically. OLEDs work by only lighting up what you’re likely to be able to see in the first place, no backlight.

I assume due to people turning up brightness when using darkmode? Or what do you mean?
Anyway, easily avoidable by using the superior light mode.

superior light mode.
Is that what we’re calling dark mode nowadays?

Yes.

I find it hard to focus on characters using dark mode.

Does that mean dark mode isn’t vegan?

It almost certainly is slightly more energy intensive, that’s just how LCDs work. I wasn’t under the impression that was why many people prefer dark mode.

Not necessarily, if the LCD has local dimming depending on the dimming zone size it could be more energy efficient in dark mode.

I just think it’s funny that, way back in the DOS days, dark mode was the only mode, then GUIs and the web were the “modern” thing, and if you didn’t like, fuck you too bad… Now we’ve gone full circle.

idc I can't read anything in light mode

Yeah I’m not doing it for the energy savings I’m doing it for personal comfort.
If I was really concerned about energy use at that scale I would simply not use a computer.
