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

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

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.
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?
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 2015.
Do you mean LCD?
No, OLED. Samsung Galaxy Note 3 is the device in question.
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.
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...
It's not negligible when running on battery...
Yes it is.
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.
Does that mean dark mode isn’t vegan?
idc I can't read anything in light 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.
I assume due to people turning up brightness when using dark mode? 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.
