Enough with this already!!!
OLED just cant provide peak brightness like LED.
This is the reason you are not seeing OLED’s on iPads XDR or their Larger display.
Look at the Sony X90J OLED. They have to use a heat sync on the back of the display in order for it to push small bursts of 1100 nits. Its just not sustainable with OLED material in its current form.
This is why MiniLED is the big push as of late. Honestly, in the TV realm, its still not perfect and has some way to go. I own a LED FALD (Non MiniLED) Sony Z8H and prefer its 2500nits of peak brightness over my LG C9 OLED.
You have to pick your poison. I am happy Apple is using MiniLED as it is one of the biggest companies that may help improve its tech. (Certainly better than Samsung/TCL)
OLED is great in some way, but it’s certainly not “The BEST”. Just depends on what you value most.
Lastly, OLED has been implemented poorly on mobile devices with digital controllers. This is one of main the reasons for the massive PWM issue that plagues ALL mobile OLED devices.
If you don’t suffer from PWM eye strain, that’s great! Just know its not great for your eyes and chances are you might develop other side effects without notice.
Your post contains several assumptions and personal opinions that you state as facts.
The reason Apple went with Miniled is just your assumption.
The Tab S7+ is very bright, some have measured the brightness to almost 600 nits and I see little difference in max brightness with my 11 pro. And even in this video, despite the much more reflective screen of the Samsung, you can see there is not much difference in brightness outdoor (the youtuber even thinks the Samsung is brighter, but I don't agree with him). I think brightness measurements vary because of the different technology of the screens.
I think that just like people should stop saying that OLED is better, people here should also stop saying that miniled is better.
They each have some pros and cons.
For some people the brightness on something like the Tab S7+ is plenty (I, for one, have never used the full brightness, while I very often need to use it on my, much less bright, 2015 iPad pro, which has 430 nits of measured brightness) and not everybody can see PWM.
For some instead, it's a deal breaker. Just as the blooming can be a deal breaker for some.
As for durability, the burn in issue worries are mainly based on older devices... My 2017 Galaxy S7, which I used till the end of 2019 and still have it, has never developed any burn it... Some people here talk as if burn-is is guaranteed to happen within a couple of years.
And nobody can tell the longevity of this mini-led display... or any new display (my IPS 10.5 iPad developed a ugly white spot and it's far from being the only one, who could predict that?).
I am glad Apple is trying a new technology with great contrast, and at some point I'll probably buy it, if the benefits seem to be more than the drawbacks and no new issues appear, but I am also glad I don't need to be a early tester, having already an Amoled device for videos that is probably just as good (maybe slightly better in some aspects and slightly worse in others).
