iPhone 15 Lineup Rumored to Feature More Power-Efficient OLED Displays

iPhone 15 models will be equipped with a more power-efficient OLED display driver chip manufactured based on a 28nm process, compared to 40nm for current models, according to a report today from Taiwan's Economic Daily News.

The primary benefit of the 28nm chip would be reduced power consumption, which could contribute to longer battery life for iPhone 15 models.

While no major display upgrades have been rumored for the next iPhones, the Dynamic Island is expected to expand to the standard iPhone 15 and iPhone 15 Plus. The bezels around the display are also expected to be thinner on the iPhone 15 Pro models, which could give those devices a similar appearance as the Apple Watch Series 8.

Isn't 2000nits enough? Genuine question . I couldn't try it as I don't have a 14 pro , but I figured it must be super bright as 1000nits on my iphone is already hella bright even under sunlight
Not really. It gets sunny in Las Vegas and we have extremely high-level of sunlight. Thus, it is not enough. I do prefer Apple Watch Ultra nits display.

This will definitely extend the daily day-to-day battery life. Hopefully, the overall brightness nits increase too.

Eh. In direct sunlight, it's still not that bright. Is it enough? Maybe, but brighter wouldn't hurt. Granted, it can't sustain that brightness for very long anyway without getting very warm.

Will this somehow affect a PWM dimming some people are struggling with?
That's what led me to dive into this article straight away.. unfortunately doesn't seem like a fundamental change to the dimming process. Hope I'm wrong. Stuck on the iPhone 11 :(

It surprises me that the SoC is moving to 3nm process, so to realize that the display driver chip is built on even 28nm process seems absurd. How has Apple not perfected this if it’s using so much energy.
These are going to be different types of transistors used in analog circuitry vs the mostly digital circuitry in the soc. So you can’t do 1:1 comparison. Probably different voltage and current requirements too
