Apple’s iPhone 13(Tentative) is already the talk of the town. It has been just two months since the predecessors’ launch, but the next iteration is hitting the news constantly. Now, a report sheds more light on the display tech of the supposed ‘Pro’ variants.

iPhone 12 Pro Max

According to a Korean report, Apple is ready to load up at least the Top 2 models of the next iPhone with a 120Hz OLED display. Besides, Samsung Display(Pro Max, mini) and LG Display(all except Pro Max) are said to be the Prime suppliers for iPhone 13 series’ displays.

Precisely, the Top-2 ‘Pro’ variants- iPhone 13 Pro, iPhone 13 Pro Max to feature the long-rumored 120Hz ProMotion display. This is in contrast to an early report that said all the models will have the high-refresh rates.

Anyway, the base variants(iPhone 13 mini, iPhone 13) will reportedly have LTPS while the Pro variants with 120Hz will feature the LTPO display. That is, LTPS is Low-Temperature Polysilicon while the LTPO is Low-Temperature Polycrystalline Oxide.

Simply put, Apple has gone with LTPO and an LTPO-TFT backplane to evade the power consumption caused due to the 120Hz. By doing so, it aims to get the best of both worlds- Advantages of LTPS and less power hungriness. If the report is true, iPhone 13 will have the following OLED display specs:

  • iPhone 13 mini- 5.4-inch LTPS display, 60Hz refresh rate.
  • iPhone 13- 6.1-inch LTPS display, 60Hz refresh rate.
  • iPhone 13 Pro- 6.1-inch LTPO display, 120Hz refresh rate.
  • iPhone 13 Pro Max- 6.7-inch LTPO display, 120Hz refresh rate.

Further, the LTPO backplane will also allow Apple to vary the refresh rate as low as 1Hz. This not only aids the Always-on scenarios well but ensures you get more screen-on time. We saw this on the Galaxy Note 20 Ultra and Apple also uses them on the Apple Watch 5 and Watch 6.

The report also says that LTPO-TFT will mean SCM(supply-chain management) will grow and suppliers get more profit(more unit price). However, Apple has to deal with changes in corresponding parts such as Driver IC, RF-PCB, OLED emitters etc.

So far, iPhone 13 series is on course to launch around September-2021 and is already rumored to bring improvements like an upgrade in ultra-wide lens, A15 bionic SoC, up to 1TB storage.
