Move done to save cost
Samsung Display will be applying different grades of materials on the OLED panels it will manufacture for the upcoming iPhone 14 series depending on the model tiers, TheElec has learned.
It will use its latest and most advanced material set for the higher tier iPhone 14 models while it will use its prior generation set for the lower tier ones, sources said. The move is being made to save cost, they said.
Samsung Display will be supplying OLED panels for all four models of the iPhone 14 series; rival LG Display will be supplying for two models.
An OLED material set is comprised of dopant, host, prime and others used to form the red, green and blue pixels.
Samsung Display calls its material sets used on Samsung’s Galaxy and Apple’s iPhones the M series.
The South Korean display maker used its LT sets in 2017 for Apple’s first OLED iPhone, the iPhone X and in 2018 iPhone XS. But starting in 2019 it begin using its M series for panels supplied for Galaxy smartphones and iPhones.
Samsung Display will use its M11 material set for the standard 6.1-inch and 6.7-inch models in the iPhone 14 series.
These phones will have low-temperature polycrystalline silicon (LTPS) thin-film transistor (TFT) OLED panels, which are less advanced than the low-temperature polycrystalline oxide (LTPO) TFT OLED panels used in the higher-tier models.
The two higher-tier models in the iPhone 14 series will use Samsung Display’s M12 material set.
This same OLED material set is being used for the OLED panels on Samsung’s upcoming foldable phones Galaxy Z Fold 4 and Galaxy Z Flip 4.
Samsung Display similarly used different materials set for the panels of the Galaxy S22 series.
OLED panels for the Ultra and Plus models used the M11 set while the standard S22 used M10.
Meanwhile, LG Display calls its OLED material set RS. It will be using the latest in the set called RS-L for the two models in the iPhone 14 series it will be supplying panels for __ the 6.1-inch standard iPhone 14 and 6.7-inch iPhone 14 Pro Max.
The company used the prior generation material set RS-K for the iPhone 13 series.
LG Display will be supplying LTPO TFT OLED panels for the first time to Cupertino for the iPhone 14 Pro Max model.
