I have experience and I know how it works. My sister just replaced an older SAamsung phone it it has very visible app icons burn ins.
It highly depends on usage and usage types.
I never doubted that you or anyone else can and will use oled devices for a long time and would not have it. I am fully aware that someone is totally ok facing this problem right when 3 year burn in warranty expires since they will just get another one.
But I think this is something you do not understand. It is unacceptable for some of us to have to replace a 1k+ display every 3 years. 3 years, is it not obvious? They are not fools, they know where the limit is.
And since you mentioned lcd, what was the last time you looked at a modern, not cheaply made, lcd display? That backlight is the thing of the past or common to the very low cost models.
I have a 2019 LG C9 running on year 5 now in my office, 4K/UHD HDR at 120 Hz, with zero burn-in. It has even been used massively for PC gaming with HUD all over on full brightness for the last 3 years. First two were mainly console, tv and movies. Flawless image quality 5+ years later.
I have seen pretty much every high-end LCD TV in the last 5 years and yeah backlight continues to be a huge issue, especially when you put the TV in game mode and dimming zones goes from 100s or 1000s to 16, 8, 4 or even disables them completely. Do you read reviews? This is a complain on all LCD TVs.
Why? Because backlight control takes up processing power and adds input lag like crazy. This is not what you want in Game Mode.
Hard to beat OLEDs 8,294,400 "dimming zones" anyway > Pixel perfect image. Per pixel control is the only way to deliver a flawless image.
LCD is doomed and OLED has already taken over high-end phone and TV market long ago. Monitor market is next. Both Samsung and LG is all-in on OLED. Even Samsung Display said LCD development is waste of money and Samsung Electronics buys 3rd party LCD panels now.
LCD is unfixable. Tech has too many flaws. That is reality for you.
You are afraid of burn-in yet accept tons of issues on DAY ONE with LCD. Funny.
Most people that are afraid of burn-in never had a newer OLED TV anyway. You ramble about stuff you have zero experience with.
LCD = Blooming and clouding, backlight bleed, smearing, bad uniformity, corner glow (both IPS and VA), bad viewing angles (wide viewing angle filter will reduce contrast big time and still viewing angles are bad), low contrast, bad HDR.
Just a few of LCDs flaws. No wonder LCD is mostly used in cheaper TVs and devices now.
Every single person that knows about actual high-end TVs use OLED for a reason. This is 2024 not 2014, OLED burn-in is a not a problem, unless you disable all software to mitigate it and runs CNN/BBC for 24/7/365 and never let pixel cleaning happen.
I will never go back to LCD again. Thats for sure. The last LCD panel in my life, is my current monitor. Will be replaced by OLED this year or next.
If you can't afford OLED, fine. But don't talk crap about a superior tech. OLED beat LCD for years in the high-end TV market and every single new mid to high end phone uses OLED and have done for years. LCD is literally dead when you talk high-end in these markets.
LCD can't be fixed. Backlight control will never improve and game mode will disable them. It is too expensive to make enough dimming zones for LCD to be relevant. Making LCD pointless. Which is why Samsung Display stopped developing LCD completely. OLED is the future till Micro LED takes over, which is 2030+ and will cost twice or triple of OLED in the first many years.
Do you even read TV reviews? OLED destoys the competition and have done for years. This is nothing new.
