Yesterday Oppo hosted its Oppo INNO Day 2020, during which it unveiled two interesting concept devices. First up is the Oppo X, a rollable OLED smartphone that can open up to increase the display size:
When closed the Oppo X has a 6.7-inch AMOLED, and when rolled open it can reach 7.4 inches. Inside the phone the display scrolls around a 6.8mm 'scroll motor'. Oppo says it applied 122 patents for this specific phone, with 12 patents protecting the scroll mechanism. This is still just a concept, and Oppo did not disclose any commercialization plans.
Oppo also unveiled a new concept AR HMD device, called the Oppo AR Glass 2021. This is again a concept device, and Oppo did not disclose much - beyond the fact that it uses 0.71-inch OLED microdisplays. These are likely to be BOE's 0.71" FHD 2000 nits microdisplays.
