Homebrew noled - Screen-off overlay to prevent OLED burn-in & save battery (all Switch models)

[Croesus]

Hey everyone,

I made a simple overlay that turns off the screen backlight while your Switch is doing something in the background — downloads, file transfers, system updates, etc.

The main motivation was OLED burn-in prevention, but since it controls the backlight directly, it works on every Switch model (V1, V2, Lite, OLED) and saves battery too.

How it works:
• Quick tap → Screen off. Device can still auto-sleep normally.
• Hold A for 1.5 seconds → Screen off + stay awake. The device won't go to sleep, so your download or transfer keeps going with the screen off.
• Press any button to exit and restore the screen.

Technical details for the curious:
- Backlight is controlled via the lbl service (no hacky workarounds)
- Stay-awake mode pings idle:sys ReportUserIsActive every 30 seconds — no system settings are changed, ever
- If the device sleeps and wakes up, the overlay detects it and exits cleanly
- If the overlay crashes for any reason, everything goes back to normal automatically

Demo:


Requirements:
- Atmosphere CFW
- Ultrahand Overlay or Tesla Menu with nx-ovlloader

Installation:
Download noled.ovl from the releases page and copy it to /switch/.overlays/ on your SD card.

Good idea, thank you!

Neat idea, thank you! I haven't tried it yet, but I'm not sure about 'Hold A for 1.5sec'...if you're playing a game where you hold A for long times...the screen may shut off...maybe better to hold a combination of keys like 'Hold A + D-pad Up'? Just an idea. Great work!

Thanks for the feedback! No worries — the hold detection only happens on the overlay's launch screen, not during gameplay. You open it through Ultrahand/Tesla Menu (L + DPad Down + Right Stick), and only then does the quick tap vs long press matter. Once the screen is off, any button press exits the overlay and restores the screen. It won't interfere with your game at all!

Good work, thanks a lot!.. Could it turn off the backlight only of the display on an IPS-model Switch (Erista/v2/Lite) but with the display on?.. Like a non-backlit E-ink displays.

So one may use external LED light with a fully working Nintendo Switch screen together.

Oh how did you get my reply When I realized that it only applies on the overlay screen, I edited my post quickly to remove that.
All good!

Hey, this is a good one. I'll be waiting for a fully customizable settings for this one. Like customizable trigger keys and adjusted timer for the hold options or you might want to add Tap times options 1x, 2x, 3x taps to turn off.
