Not for OLEDs. I just tested my LG C1, 64 watt difference between full screen black #0000000 and full screen white #FFFFFF at 120hz

- Dma54rhs 4y agoWhat was the difference?
- always2slow 4y ago64 watts?
- scrollaway 4y agoThe campaign referenced by GP is very old. It dates from before OLEDs. LCDs were the most common screen type and CRTs second most common at the time.
- Melatonic 4y agoHow much does it draw in total before / after? Curious how much of a percentage change this is
- always2slow 4y ago228w - total system draw with LG C1 off/standby 270w - #000000 fullscreen 332w - #FFFFFF fullscreen 270w-228w = 42w #000000 fullscreen power draw 332w-228w = 104w #FFFFFF fullscreen power draw ( 104w - 42w ) / 42w = 2.4761 so ~248% more power usage from the screen for full #FFFFFF. One thing to note is I have the OLED pixel brightness set to 50/100 and the brightness set to 50/100. 2.2 Gamma, black level: full. The LG C1 has some auto brightness baked into the firmware and it fluctuates, I tried to measure it at full brightness but as you can see today it's at 62w over #000000 compared to before so there is some deviation. However, I think it's safe to say that darker colors do actually save substantial power on OLED displays. Plus the black levels really are just amazing. Black is actually black and not a weird grayish with backlight shining through like TN/IPS LCDs. edit: formatting.
