The iPhone 13 series is still very far away, but various rumours have already been flying in the sky, such as the screen, the 120Hz high refresh rate is finally expected to be realized, making up for the regret that the iPhone 12 series only has 60Hz.
According to the latest report from Korean tech website ETNews, the iPhone 13 series will have four models, continuing the existing layout, named iPhone 13 mini, iPhone 13, iPhone 13 Pro, and iPhone 13 Pro Max. The screen size will also continue the existing specifications. They are 5.1, 6.1, 6.1, and 6.7 inches.
Among them, the iPhone 13 mini and iPhone 13 both use the traditional LTPS OLED, and the refresh rate is maintained at 60Hz. The iPhone 13 Pro and iPhone 13 Pro Max will be upgraded to the new LTPO OLED, and the refresh rate is also up to 120Hz.
LTPS (low-temperature polysilicon) is currently the most mature OLED technology, but the power consumption will increase significantly at high refresh rates. This is also considered to be the main reason why the iPhone 12 does not have a high refresh rate screen.
LTPO (Low-Temperature Polycrystalline Oxide) is a new type of OLED technology, which combines the advantages of LTPS and IGZO technologies, adds an oxide layer, can achieve higher charge mobility at a lower cost, and the refresh rate can be adjusted according to the display The content is switched between 1-120Hz, thereby greatly reducing power consumption.
At present, Apple Watch has introduced LTPO technology to achieve 18 hours of long battery life under constant screen display.
As for the iPhone 13’s screen suppliers, Samsung and LG are currently considered most likely, while BOE continues to miss out.
