iPhone 13: All the major rumors about Apple's next-gen iPhone.'Otherwise it's going to cost you in terms of power.'Īpple didn't specifically say it's using LTPO, but it's the only way to deliver ProMotion's abilities on the iPhone, Young said. 'If you want a high refresh rate phone, this is the way to go,' Display Supply Chain's Ross Young said of LTPO. With an earlier technology called LTPS, short for low temperature polysilicon, displays flicker distractingly at low refresh rates. LTPO helps by gracefully accommodating both high and low frame rates that bottom out at one screen refresh per second for super high efficiency. But high refresh rates require a lot of power, which is why many phones supporting it allow users to disable it for better battery life. The quick refresh rates make for smooth scrolling and help games look their best. The usual rate is 60 times per second (60Hz), but high refresh rates can reach 90Hz or 120Hz. One way to improve smartphones these days is with high refresh rates that rapidly repaint the screen. Here's a look at what LTPO is and how it works. LTPO also is built into some Apple Watch displays. Samsung's Galaxy Note 20 Ultra, Galaxy Z Fold 2 and Galaxy S21 Ultra Oppo's Find X3 Pro and OnePlus' 9 Pro all take advantage of the technology. ProMotion 'produces fast frame rates when you need them and preserves battery life when you don't,' Apple's marketing chief, Greg Joswiak, said at the iPhone 13 launch event.Īpple isn't the first phone maker to use LTPO. On the iPhone 13 Pro and Pro Max, LTPO enables ProMotion's ability to dial screen refresh rates between 10 times per second (10Hz) and 120Hz.
