iPhone 15 to Receive Upgraded OLED Display Chip for Better Efficiency & Battery Life

iPhone 15 Pro Max-White

A new report from Taiwan’s Economic Daily News has suggested that Apple’s iPhone 15 models will come equipped with an upgraded OLED display chip. This new chip is expected to be more power-efficient, reducing power consumption and improving battery life.

According to the report, the OLED driver chip used in the iPhone 15 series will be upgraded from 40nm HV to 28nm HV. The chip controls the on and off of pixels, and is situated between the main CPU and the display.

Supply chain sources also indicate that LX Semicon and Samsung System LSI are the core suppliers of Apple OLED drive chips. 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, and Grid Core OEM.

The shift to a 28nm OLED driver chip is a significant development for Apple as it continues to improve its devices’ efficiency and battery life. Apple has always focused on enhancing user experience, and longer battery life is a crucial aspect of that.

In related news, a recent leak suggested that the iPhone 15 Pro and iPhone 15 Pro Max models could feature a display that is much brighter than the current iPhone 14 Pro models. The upgraded display is expected to reach up to 2,500 nits of brightness, which is significantly brighter than the current maximum brightness of 1,000 nits for the iPhone 14 Pro and Pro Max.

The same leaker also claimed that the standard iPhone models would feature the same display design as the iPhone 14 models, while the Pro models would feature thinner bezels with curved edges.

This design change will give the Pro models a more modern look and feel, and could appeal to users who are looking for a more premium experience.
