Chinese display maker BOE has partnered with touch panel maker General Interface Solutions as both companies aim to become suppliers of Apple's rumored 5.4-inch iPhone, according to a paywalled report from DigiTimes Apple plans to release four so-called iPhone 12 models with OLED displays in the fall, including one 5.4-inch model, two 6.1-inch models, and one 6.7-inch model, according to analyst Ming-Chi Kuo. All of the devices are expected to support 5G and they may sport a new design that includes more of a flat edged metal frame like the iPad Pro or iPhone 4.The new 5.4-inch iPhone would be the smallest iPhone that Apple has ever offered with a notched display. By comparison, the iPhone 11 Pro has a 5.8-inch display and the iPhone 11 Pro Max has a 6.5-inch display. With a notch, slim bezels, and lack of a home button, the 5.4-inch iPhone would have an even smaller footprint than the 4.7-inch iPhone 8.Whereas the highest-end iPhone 12 models are expected to sport triple-lens rear camera systems with a time-of-flight sensor for 3D sensing, mid-range models like the 5.4-inch iPhone are said to have a dual-lens array and, according to 9to5Mac , may lack 3D sensing.
