As the production for the iPhone 14 has already started, we’re getting more details about the upcoming phone. According to a recent report, Samsung Display is adding a new supplier for the OLED material that will be used on the iPhone 14 lineup.

Samsung Display is probably going to be adding Solus Advanced Material as a supplier for layers in the M12 OLED material set. Samsung is probably using Hodogaya Chemical as a supplier for the latest M11 material set.

Samsung Display is also likely to procure G prime, another material used in OLED production, from Merck DS, which it has previously relied solely on DS Neolux for

OLED layers are composed and stacked, from the bottom, of the anode, hole insertion layer, hole transport layer, emission layer, electron transport layer, electron injection layer, and cathode (anode-HIL-HTL-EML-ETL-EIL-cathode). CPL is then placed on the cathode to adjust the optical characteristic of the layer. G prime is part of the emission layer and supports the green color.

All of these different changes from Samsung Display do not change the final product. It’s still interesting to see this battle of suppliers to participate in Apple’s iPhone production, They are very valuable, of course.
