The Find N2 Flip starts at roughly $860 when converted from its price in China of 5,999 yuan.
International prices are set to be revealed during the official global launch next year.
The second display takes the form of a 6.8-inch AMOLED panel.
Oppo says it has an ultra-thin glass coating that should help with durability.
According to the company, Find N2 Flip has been tested for 400,000 folds.
This inner display is also home to a hole-punch cutout for the 32-megapixel front-facing camera.
The rear camera module consists of a 50-megapixel main camera and an 8-megapixel ultra-wide.
