Only ‘Pro’ Variants of the Apple iPhone 13 will feature 120Hz LTPO display: Report

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.
