Apple’s upcoming iPhone 15 models will boast a more power-efficient OLED display driver chip, which is manufactured based on a 28nm process, says a report from Taiwan’s Economic Daily News. Current iPhone displays are built using a 40nm process.
The 28nm chip’s major benefit would be reduced power consumption, which could result in longer battery life for the iPhone 15 models.
EDM says the process shift is taking place just as select manufacturers, like LX Semicon and Samsung System LSI, are migrating their chip process. Apple is likely looking to take advantage of the new production lines, which will also push its other suppliers to use the new process faster.
Apple’s high demand for the new chips is likely to cause an industry shortage of 28nm production capacity, says the Taiwanese publication.
Supply chain sources revealed that the process of Apple iPhone 15 series OLED driver chip will be upgraded from 40nm HV to 28nm HV, which will help further reduce power consumption and improve battery life.
According to the report of Jiwei.com, at present, the core suppliers of Apple OLED drive chips are LX Semicon and Samsung System LSI, among which Samsung System LSI driver chips are mainly OEM by Samsung Electronics and United Power, and LX Semicon drive chips are mainly driven by TSMC, United Power, Grid Core OEM.
The iPhone 14 Pro’s “Dynamic Island” feature is expected to expand to the entire iPhone 15 lineup, including the iPhone 15 and iPhone 15 Plus.
