GoKawiilTCL's P80 Ultra combines OLED display with e-reader mode
TCL unveiled the P80 Ultra, the first phone to use its OLED version of Nxtpaper technology, which was previewed at MWC earlier this year. The 6.83-inch screen offers flagship-grade specs including 1.5K resolution, 120Hz refresh rate and 3,200 nits brightness, but can switch into a monochromatic 'Max Ink Mode' that mimics an e-reader and extends battery life to up to a week of active use.
