In October 2020 TCL's CSoT demonstrated some new rollable OLED technologies, and today at CES the company published this nice video you see below that again demonstrates new rollable OLEDs:

TCL first shows a rollable smartphone, that uses a 7.8-inch AMOLED that rolls into a 6.7-inch one. The display features a bending radius of 3 mm and CSoT says it can withstand up to 100,000 sliding cycles.

The second display is a 17-inch rollable OLED - suitable for rollable tablets. The 0.18 mm thick 17" display was produced using an ink-jet printing process.
