The iPhone 15 is expected to have a similar display to the iPhone 14, with a 6.1-inch OLED panel on the base model and a 6.7-inch OLED panel on the Pro Max model. However, there are some rumors that Apple may be working on a new display technology called "MicroLED." MicroLED displays are brighter, more energy-efficient, and more durable than OLED displays, so they could be a significant upgrade for the iPhone 15.
