iPhone 15 OLED displays will be more power efficient

This year’s iPhone 15 lineup will feature OLED displays that are more power-efficient thanks to an upgraded driver chip. Apple reportedly plans to switch from its current 40nm process for OLED display driver chips to a 28nm process.

Apple’s OLED display chip will receive an upgrade with this year’s iPhone 15 models

According to a new report from Taiwan’s Economic Daily News, a more power-efficient OLED display driver chip will be used in the iPhone 15 lineup. This chip controls the actual turning on and off of the pixels and is located in between the main CPU and the display.

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 primary benefit of the 28nm chip would be reduced power consumption, which could contribute to longer battery life for iPhone 15 models.

In related news, a leaker recently claimed that this year’s iPhone 15 Pro and iPhone 15 Pro Max may receive a display that is much brighter than the display of the current iPhone 14 Pro models. The upgraded display could reach up to 2,500 nits of brightness. For comparison, the maximum brightness of the iPhone 14 Pro and Pro Max is typically 1,000 nits, increasing to 1,600 nits for HDR content and 2,000 nits for outdoor use.

The same leaker has also said that this year’s standard iPhone models will feature the same display design as the iPhone 14 models. In contrast, the Pro models will feature thinner bezels with curved edges.
