Samsung, who is Apple’s chief OLED supplier for the iPhone 13 Pro and iPhone 13 Pro Max, will not provide the technology giant will panels for the company’s first OLED iPad Air next year. According to the latest report, the reason has to do with both companies being unable to reach an agreement.

Samsung has apparently only mass produced a single stack OLED panel structure. What this means is that there is only one emission layer, which The Elec reports can compromise on the overall brightness levels, which Apple is not too pleased about. However, another downside of single stack panel structures is that the OLED iPad Air may have a shorter lifespan as the panel itself might give out in a couple of years.
