From what I have heard this is a problem with OLED panels.

I frequently use apps with "night" theme (black background, white UI controls). You know how Android apps have "back" button on the top-left corner, right? There is also a navbar (back/home/recent buttons). In my case it's a white-ish rectangle that's almost always present on screen. By the time Samsung added an option to hide it, the damage was already done. I have them both burnt in on my screen. I first noticed th…

I've been using OLED for a long time now, and never had this OLED burn in - including one particular phone (Ativ S, so Samsung S3 screen) that was in use by me for years and then used as a navigation system by my mother until the battery perished. However, someone I know had a phone (I believe the Samsung S8) nearly constantly playing videos with full brightness, and there it did show red streaks over the screen. I wonder what kind of usage triggers it.

I had heard of this before, but didn't know that screensavers were designed to prevent that damage from happening. In this case, the bouncing DVD logo seems like an odd choice, as the way it's designed, there are certain pixels on the screen that it will never cross (corners, for example), which would fail to serve the desired purpose. Can someone explain?

There was a video going around of the logo hitting the corner perfect and a room full of people got real excited

I still buy DVDs because I like classic movies and for those movies it doesn't matter whether you watch in dvd quality or Blu-ray. Plus DVD rips are significantly smaller in size and even though I have Blu-rays for some movies I don't have a Blu-ray player on my computer to rip them. So effectively my preference is to buy DVD, unless it's a relatively modern movie (post 90s)

Not true. Movies were of course shot on film, which has way higher resolution than DVD. Even old TV shows look better than ever, as long as they were scanned from film. Look at the original Star Trek or Twilight Zone on Blu-Ray.

You're talking about the most popular movies that were transfered to digital or even restored. Most films weren't. Plus, we lost immense amounts (most) of cinema that was produced before ~1950s when better film started being used.

A while ago I made a bouncing DVD logo that would actually hit the corner every few bounces with high probability: https://nikital.github.io/screensaver (But then it would troll you just before hitting it)

Earlier I commented about turning it into a mac screensaver. Well, I went ahead and did it. Used your code, but didnt have a license. Do I have your permission? Here is the link to the repo: https://github.com/pabloriveracelerity/mac-dvd-screensaver Please let me know if you do not approve and I will take it down ASAP. No ill intentions. Just wanted to join the fun. :)

xscreensaver's BSOD module has a DVD logo mode too. :)

Let's hope we just stick to black screens to save some power and prevent burn-in at the same time.

Why didn't we do this back in the CRT era, and invented screensaver instead, then? TV is understandable, you don't want a DVD player to show a black screen, otherwise it appears dead. But what about screensavers on computers, why did it come into being? (I know turning a CRT on takes time, but we don't have to turn it off completely to blank the screen either?) Update: It appears that the original motivation was publ…

There is something to say for knowing that the device is on. Saves you from accidentally turning the device off when you wanted to turn it on.

In 1999, my DVD player could do this smoothly without any hitches or glitches. In 2020, my Xeon can't render this fast enough to avoid stutters. Either code quality has gone way down or my DVD player had a faster CPU.

It's just a less-than-ideal implementation, your CPU is most definitely not suffering. Here is a completely smooth version: https://codesandbox.io/s/nostalgic-cherry-wwpzj?file=/src/in... (I made the exact same thing last year as a joke for our team monitors)

Yeah, it's not perfectly smooth for me (MBP 2019, Chrome).

I think adding `will-change: transform` might help a bit, to hint the user agent that you'll be animating transforms...

How are you watching a film on DVD if it hasn't been transferred to digital?

The LCDs you see this on are 6-bit color displays using temporal dithering to pretend to be 8-bit color.

That's why drop shadows look horrible when I'm looking at my screen at the wrong angle... I knew it was a dithering thing, forgot LCDs were 6-bit.

Only cheap/low-end LCDs are 6 bit. Most are 8 bit with no dithering.
