According to South Korean outlet The Elec. Samsung and LG have started production of OLED panels for this year's iPhone 13 series.
2021's lineup is also rumored to feature four models: 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.
Samsung is manufacturing low-temperature polycrystalline oxide (LTPO) OLED panels with upto 120Hz refresh rate support for the iPhone 13 Pro and iPhone 13 Pro Max, even though we have heard any rumours that’s saying it will come in both pro models.
This Refresh rate was rumoured to be added in the iPhone 12 Pro Max but apple thought that a 120Hz screen on top of 5G connectivity would be too big a drain on battery life so no. With LTPO units, this won't be an issue.
Last Year’s Galaxy Note 20 Ultra has this as well . The Galaxy S21 series features a more efficient version of the tech.
If you don't know, LTPO enables a screen to dynamically change its refresh rate
The LTPO panel is also likely to finally bring Always On Display to iPhones as well. Which is always a good step.
LG on the other hand is manufacturing conventional low-temperature polycrystalline silicon (LTPS) TFT OLED panels for the iPhone 13 mini and the iPhone 13. These models are not expected to support a high refresh rate and will retain the standard 60Hz screen.
The report also points out that OLED production for the iPhone 13 series has started a month earlier than last year.
Talking about the numbers, Samsung will manufacture 80 million display units for the new iPhones, and LG is expected to supply 30 million panels only.
Per a recent report, the A15 Bionic chip that will power the iPhone 13 range has also entered production. But it will still be a 5nm chip though.
The new models will allegedly also feature a slightly updated design with a smaller notch, bigger camera module and in-display Touch ID. Face ID will be there as well.
