I suspect this isn’t the case with an OLED, since it wouldn’t even emit any blue light in the first place if those pixels aren’t on. However, a typical laptop / monitor will have a white backlight that then gets blocked. Often there’s bleed through even if the screen is completely black.
If someone with more specific knowledge about screens corrects me, I yield to their judgment. :)
- shadowprofile77 7y agotech writer who specializes in TV screens here. You are indeed correct. With OLED, no bleed-through at all exists since there is no backlight and unless specific RGBW pixels on the screen are activated, they emit no light at all basically. On the other hand, even the absolute best consumer market LCD/LED screens leak at least some backlight glow, though in high quality models it becomes very faint due to local dimming zones and high quality light blocking.
