Digitimes.com reports that Apple is laying the groundwork in the supply chain to launch three new iPhones in 2020 featuring OLED displays.

The current flagship lineup offers OLED screens on iPhone XS and iPhone XS Max but the iPhone XR uses a lower-resolution LCD panel.

This pattern is set to continue for the 2019 generation but Apple will shake things up next year. The three 2020 iPhones will reportedly come in new screen sizes: 5.42-inch, 6.06-inch and 6.67-inch.

The Wall Street Journal had previously reported that Apple will switch to using OLED displays exclusively for its phone models from next year.

The different sizes quoted in the report suggest major design changes for the phones. 6.67-inches would make for the largest iPhone ever, at least in terms of screen size.

Samsung Display is likely to remain the primary OLED panel supplier of Apple in 2020, and it remains to be seen whether LG Display or BOE Technology can obtain OLED panel orders from Apple.

This year's updates to the iPhone XS, iPhone XS Max and iPhone XR are expected to bring camera upgrades including a dual-camera module as standard on the iPhone XR and a triple-lens option on some models. Apple analyst Ming-Chi Kuo believes that the 2019 iPhones will include a reverse wireless charging feature, which would allow iPhone owners to charge their other devices simply by placing them on the back of the iPhone. The feature is one of the highlight features of Samsung’s Galaxy S10 line.

Two-way wireless charging would also mean that the iPhone may need bigger batteries. Kuo states that Apple could bump up the battery capacity on the 6.5-inch Max model by 10-15%, 20-25% on the regular 5.8-inch OLED model, and 0-5% on the cheaper 6.1-inch LCD model.

Apple will announce its trio of new phones in the fall, likely at a September media event.
