iPhone 14 models to feature different grades of OLED panels

San Francisco: Tech giant Apple plans to use different OLED panel qualities for its upcoming iPhone 14 and iPhone 14 Pro, the media report reports.

According to TheElec, Samsung Display will apply different types of materials to the OLED panels it will produce for the upcoming iPhone 14 series, depending on the model tiers.

It will use its latest and most advanced material set for the higher-level iPhone 14 models, while it will use its earlier generation for the lower-end models. The move is done to save costs.

Samsung Display to supply OLED panels for all four iPhone 14 series models; competitor LG Display will ship for two models, citing sources, the report said.

An OLED material set consists of dopant, host, prime and others which are 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 iPhone XS in 2018. But from 2019, it started 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 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-end models.

The two higher end models in the iPhone 14 series will use Samsung Display’s M12 material set.

The same OLED material set is used for the OLED panels of Samsung’s foldable phones Galaxy Z Fold 4 and Galaxy Z Flip 4.
