The iPhone 13 mini and iPhone 13 will reportedly have LPTS (LTPS is Low-Temperature Polysilicon), while the Pro variants are expected to feature LTPO (Low-Temperature Polycrystalline Oxide) display with 120Hz refresh rate. Apple is said to have adopted the LTPO and LTPO-TFT to reduce the power consumption caused by the 120Hz displays. The report has also tipped the display sizes of the iPhone 13 series, which remains unchanged from the predecessor.
- iPhone 13 mini — 5.4-inch LTPS 60Hz display
- iPhone 13 — 6.1-inch LTPS 60Hz display
- iPhone 13 Pro — 6.1-inch LTPO 120Hz display
- iPhone 13 Pro Max — 6.7-inch LTPO 120Hz display
Furthermore, the LTPO technology will also allow Apple to vary the refresh rate as low as 1Hz depending on the content on the screen, thereby ensuring more screen-on time. Apple uses the same technology on the Watch Series 5 and 6. The report further adds that LTPO-TFT display will help SCM (supply-chain management) to grow. Apple will have to deal with component changes such as Driver-IC, RF-PCB, OLED emitters, and others. While there’s no exact timeline for the iPhone 13 launch, the unveiling should be held in September 2021 unless there are no delays like this year.
