OPPO’s annual event dubbed INNO DAY is usually a highly anticipated one. The Chinese manufacturer is known to showcase new and breathtaking technologies it has been developing. This year’s edition is set for tomorrow, November 17, and a new poster released by OPPO teases a concept device with a rollable display.

The image was posted on Weibo with a caption that roughly translates into “Big screen? Small screen? Infinite screen? In the future, your mobile phone may be able to retract freely”.

The poster shows a render of a phone with a curved screen with a display that can be extended or retracted to change the size.

OPPO joins the growing list of other manufacturers working on a phone with a display that can be rolled. The list has manufacturers such as TCL who showcased a rollable phone early this year. A working prototype was even leaked last month. There is also LG who patented a phone with a rollable design back in 2019 and may be planning to launch one in the near future as one of the products from its Explorer Project.

Earlier this month, an OPPO patent for a device with a rollable display was published by the China National Intellectual Property Administration. There is a possibility the device that will be showcased at tomorrow’s event may be based on this patent.

OPPO’s Weibo post clearly says this is a concept device, so don’t raise your hopes, expecting to purchase one soon. Nevertheless, a working concept means the era of rollable phones draws closer, and we can’t wait for it to be here.
