New Delhi, Jan 10 : Samsung is reportedly going to be the exclusive supplier of OLED panels used in two top-end iPhone 13 models later this year, a new report has claimed. Both models of iPhone 13 will use low-temperature polycrystalline oxide (LTPO) thin-film transistors (TFT) OLED panels made by Samsung Display, reports South Korean website The Elec. "Apple's iPhone 13 will have four models and all of them will use OLED panels. The top two models will use LTPO OLED that can support a 120Hz refresh rate", the report mentioned. The iPhone 13 lineup may mirror the iPhone 12 family of phones, with a 5.4-inch iPhone 13 Mini, 6.1-inch iPhone 13, 6.1-inch iPhone 13 Pro and 6.7-inch iPhone 13 Pro Max. In addition, the Ultra Wide cameras on the two high-end models will be significantly upgraded to f/1.8, 6P (six-element lens) with autofocus.
