TCL's display-development subsidiary CSOT has prepared 2 of its flexible prototypes that can function when paired to rollers for display at CES 2021. One is the extendable AMOLED panel that may have been seen as part of a concept smartphone before. The other is a 17-inch piece of OLED that may show what the OEM can offer the makers of devices such as transparent TVs.

CSOT is a division of the OEM TCL with a focus on mini-LED, micro-LED, OLED and QLED panels. It has come to CES 2021 to demonstrate its recent breakthroughs in rollable panels. They consist of its "scrollable" OLED that can extend to 17 inches in size, and the 6.7-7.8-inch similarly adjustable AMOLED panel that might also have featured in a recent rollable phone leak.

TCL CSOT asserts that its scrollable prototype has been made using an OLED-printing process that results in panels costing 20% less than traditional technologies. The display itself is apparently rated for 100% of the RGB color gamut and is just 0.18 millimeters (mm) in thickness.

Therefore, the company might now be closer than ever to scaling this flexible display up to sizes that manufacturers of next-gen foldables, rollable TVs, curved displays or advertising-grade transparent displays might want.

CSOT's new take on AMOLED, on the other hand, is intended to be part of more portable electronics. It is currently integrated into TCL's prototype rollable phone, which was confirmed to be less than 10mm high in this presentation. It can also apparently withstand 100,000 sliding motions and has a UI that apparently switches easily from phone- to tablet-like use-cases.

Its advanced flexible panel has a minimum radius of just 3 millimeters, which might help with its stability and durability. However, TCL CSOT did not confirm or deny the possibility of this concept seeing the light of day as a marketable device any time soon.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
