This is exciting if the rumour is true. Only 2 models for 2021 though. I would have thought that like the original OLED roll-out Apple would start with the top Pro models for 2021 but there is no guarantee of that. If Apple is nervous about yields on bigger screens then maybe not the Pros but it would be so odd for a smaller phone to have a premium feature (ProMotion) and the Pro models not to have it that if that were the case I would think that Apple would delay the whole roll out for a year to make sure it could deliver LPTO for the biggest Pro screens.
Does anyone have any numbers on this LPTO stuff? When they say more efficient what sort of reduction in power consumption are they talking about vs OLED at the same brightness for various screen states (e.g. worst case all white and maybe 25% and 50% white pixels against black background). I guess this stuff is a bit difficult to compare given how both OLED and LPTO power consumption varies based on screen content.
As someone who spends many hours reading ebooks on my phone the talk of refresh rates as low as 1Hz sounds interesting. I really hope that regular apps that display mostly static content are able to drop down to really low refresh rates because that would be ideal for my Kindle reading. I already have it set to white text on black background to get maximum power savings from the OLED screen but if it could also drop to a really low refresh rate for everything except when I turn a page I would hope that would get me many more hours of ebook screen-on time from a single charge.
I think I also read somewhere that LPTO backplanes are thinner than regular OLED ones so the display panel gets a bit thinner. Is that correct? If so then as long as Apple doesn't use that to make the phones even thinner next year (please no, the camera bump is already getting more and more prominent as the body gets thinner) that could also allow slightly bigger battery capacities next year. And it looks pretty definite that Apple will move to the Qualcomm 5nm X60 modem which should be another significant power saving.
Yes, 2021 will almost certainly be a sort of "s" upgrade since it will probably be improved components in an identical form factor but with some of these rumours the 2021 phones actually look to be shaping up to be pretty worthwhile upgrades.
As a fairly heavy ebook consumer myself - I have never been able to move away from the kindle paperwhite. The device comes with the clunkiness of the touch technology on the screen, but the reading experience itself is unbeatable. White text on black screen feels too unnatural. White background is always too intense even at dimmest settings. But I do have to whip out the trusty iPad for technical books. Kindle's no good for that.
Anyways, I always have wondered who would LTPO benefit? Most of the phone content is pretty fast moving - videos, social media feeds, other apps, etc. And if the benefit is actually to put 120 hz refresh rate, how does that square off against benefit that can be gained by reducing the refresh rate? It's not as if phones need always-on display of a watch face. Or any low refresh content - except reading which surely is not the only usecase they can be targetting.
