Yet Apple is rumoured to be bringing OLED to iPads next year... just like they brought OLED to the iPhones.

they might bring oled to the lower end ipads but not the ipad pro 12.9 inch. Maybe the 11 inch will get an oled screen. The point is that OLED is old technology at this point, it has advantages like a big color gamut and low black levels but that’s where the advantages end.

Please explain in further detail.
OLED is organic, therefore it will always be more expensive than LED/LCD. It’s hard to work with because of this as well.

It has a lot of drawbacks as in it has burn in issues, it has color shift when viewed from the sides (LCD doesn’t have this glaring issue LCD gets a bit dimmer but the color does not shift from Off axis viewing), OLED also requires a higher resolution to get the same picture quality as LCD/LED which is actually why the iPhone X has a higher resolution screen than the iPhone 8 but doesn’t look any clearer.

Since OLED (at this time) uses pentile arrangement for the subpixels (it means the subpixels are arranged not in the regular Red Green Blue orientation but instead they’re arranged something like Red Green Blue Green Red Green Blue Green) — this means that in order to get the same clarity the overall resolution needs to be higher, which means that any “benefit” created from the OLED blacks to save battery power is destroyed because of the inherent higher resolution required for the same clarity. This is why apple chose around 720p for the iphone 11 since it has an LCD display And why the iphone 11 looks so great even compared to the iPhone X display (They both are about the same amount of subpixels per inch).

Because OLED uses this different arrangement it means higher resolution displays are actually not as high as they seem. In other words, a Mini LED screen that is 4K is going to be clearer than a OLED 4K screen with a pentile arrangement.

TL;DR
- OLED uses a different pixel arrangement which means that a 4K OLED screen does not have the same clarity as a 4K LCD display.
- OLED cannot get as bright as an LCD which means the contrast ratio is not as good as the upcoming Micro-LED displays since they can get brighter but also have perfect blacks.
- OLED has color shift when viewed off axis LCD only gets slightly dimmer off axis instead.
- OLED has burn in issues because it is organic which also increases the cost!

There are no upcoming micro-LED displays for Macs or iPads anytime soon.

Is it worth it? Depends. Others have said, resolution difference on an iPad maybe noticeable but it's going to be relatively minimal. Where the most notable difference is going to be is in the the HDR implementation. Most iPads can't properly do HDR right now. I am not sure of the specs of your devices, but accepting and being able to process HDR is TOTALLY different than being able to properly display it. They can probably accept it, but the contrast ratio may or may not be up to par. I know the iPhone 11 Pro has a higher peak brightness capability so it is able to better display HDR content. The Pro XDR screen coming on the 12.9 iPad Pro theoretically will be the most capable of all the consumer-available devices, at least that Apple makes. Because of the capabilities of that screen, 1,000,000:1 contrast ratio; the peak brightness capabilities of 1600nits, covering the full P3 color gamut, it should be able to very properly display HDR. Truthfully those numbers rival some of the best 4K/HDR TV capabilities even.

600nits that's on the current iPad Pros are nothing to sneeze at either, however, the contrast ratio is somewhat sub-par. There's a difference with raised blacks and having 600nits peak brightness (that the current ipads are capable of) versus having proper blacks and 600nits, (ie LG OLED TVs).

Myself having a 2017 12.9, I don’t think it’s even supported for Netflix HDR. ??‍♂️

Anyone know? ?

Okay Sorry. So the upcoming micro-LEDS that are not yet ready But are coming soon. remember soon is a relative term and to me 5-10 years is soon.

Mini LED is better as well. All I was saying is that the Micro LED that will eventually come up are going to be even more superior than the Mini LEDS which are already the best displays.

Anyways, everything I said still stands. OLED is inferior in most ways. Apple knew this and it’s why they have been reluctant on switching to it for so long. It had to catch up to LCD and even now it’s not surpassing it they’re neck and neck with LCD improving at far fasting rates with the new mini leds and upcoming micro leds.
