TCL's CSoT demonstrated some interesting new displays at the DTC 2020 conference a few days ago - including rollable OLEDs, foldable OLEDs, ink-jet printed rollable OLEDs and new microLED prototypes.
In the video above, you can first see the company's latest inkjet-printed rollable OLED, with a size of 17-inch. CSoT says that it managed to reduce the OLED thickness by removing the color filters it used in earlier designs, which improves the flexibility - as you can see this display rolls up very nicely.
Interestingly in the video you can see what seems to be a large OLED TV that is rollable - maybe this is the 31" rollable OLED display already unveiled earlier this year, or maybe even a larger one, we do not have more information on that display yet.
In the photo above you can see another prototype, this one is an extending-rolling phone prototype (similar to what LG is likely to be launching next year). This display is 6.7-inch in size, and it scrolls to become a smaller 4.5-inch display device. The roll radius is 3 mm and TCL says this OLED has passed over 200,000 rolling cycles. A few months ago TCL unveiled a similar device, but that scrolls to the side.
