12.9-inch iPad Pro mini-LED display is as custom as its M1 SoC, but early issues have emerged

Apple has detailed the technology behind the new mini-LED display found on the new iPad Pro 12.9-inch model. Like Apple’s custom A-series chips, the new panel is a custom Apple design and features proprietary algorithms to help it function. However, some users have also been reporting blooming issues that the new tech was supposed to minimize.

Apple likes to develop its own technologies where it can in order to differentiate itself from the competition. It’s custom A-series chips really stand out in this regard as being well ahead of the competition in many regards. The company’s latest Liquid Retina XDR display found in the new 12.9-inch iPad Pro model is no exception. Even though it isn’t the first mini-LED device to hit the market, it is the only to feature in-house Apple tech.

A new support document from the company explains some of the highlights of the new panel:

The 12.9-inch Liquid Retina XDR display has an IPS LCD panel supporting a resolution of 2732 by 2048 pixels for a total of 5.6 million pixels with 264 pixels per inch. To achieve Extreme Dynamic Range required an entirely new display architecture on iPad Pro. The all new 2D mini-LED backlighting system with individually controlled local dimming zones was the best choice for delivering the extremely high full-screen brightness and contrast ratio, and off-axis color accuracy, that creative professionals depend on for their workflows.

Additionally, custom algorithms run on the advanced display engine of the M1 chip, working at the pixel level to control the mini-LED and LCD layers of the display separately, treating them as two distinct displays. These proprietary algorithms coordinate the mini-LED and LCD layers across transitions to deliver the optimal visual experience. 

Apple, however, acknowledges that like other displays with local dimming zones, the new iPad Pro panel will display “a slight blur or color change while scrolling against black backgrounds,” which it calls “normal behaviour. However, there have been some users who have noticed that a display blooming effect is still noticeable even when not scrolling with whiter light bleeding out from behind colored areas against a black background. Apple hasn’t commented on these early reports, although it is possible that the mini-LED algorithm could be further tweaked in a future update to mitigate against this effect. On the plus side, early reports also indicate that the new iPad Pro display produces OLED-like truer blacks as promised.

I have been writing about consumer technology over the past ten years, previously with the former MacNN and Electronista, and now Notebookcheck since 2017. My first computer was an Apple ][c and this sparked a passion for Apple, but also technology in general. In the past decade, I’ve become increasingly platform agnostic and love to get my hands on and explore as much technology as I can get my hand on. Whether it is Windows, Mac, iOS, Android, Linux, Nintendo, Xbox, or PlayStation, each has plenty to offer and has given me great joy exploring them all. I was drawn to writing about tech because I love learning about the latest devices and also sharing whatever insights my experience can bring to the site and its readership.
