The iPhone 13 series is still very good, but various rumors have already been flying, such as the screen, the high refresh rate of 120Hz is finally expected to be realized, making up for the regret that the iPhone 12 series only has 60Hz.
According to the latest announcement by Korean media 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, respectively. 5.1, 6.1, 6.1, 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 Polycrystalline Silicon) is currently the most mature OLED backplane technology, but 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 brush.
LTPO (Low Temperature Polycrystalline Oxide) is a new type of OLED backplane technology, which combines the advantages of LTPS and IGZO technologies, adds an oxide layer, and can achieve higher charge mobility at a lower cost. 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 backplane technology to achieve 18 hours of long battery life under constant screen display.
