According to a new report, Apple has sourced LTPO OLED screens from LG for next year's Pro iPhones. These low-power panels may pave the way for Apple enabling a 120 Hz 'ProMotion' refresh rate on the iPhone 13 Pro and iPhone 13 Pro Max. Apparently, the company supposedly decided against including high-refresh-rate displays on the iPhone 12 series in favour of battery life.
