Rollable OLED displays are exciting - as these displays can enable new device form factors - such as TVs that roll up into a small cylinder or a tablet-sized device that can roll-up into a pen.
Rollable OLED TVs
In early 2019, LG launched the world's first rollable OLED device - a TV that rolls into its base. The 65" Signature OLED TV R has three viewing options - full view, line view and zero view. This is a radical new TV form factor which carries an extremely high price. Hopefully prices will be reduced as the technology matures.
Rollable mobile devices
While LG is leading the race to rollable OLED TVs, many display makers are developing smaller rollable OLED displays for mobile devices. Commercial adoption hasn't started yet, but it is likely that we will see the first rollable OLED smartphone in the market by the end of 2021 or early 2022.

The display offered a rollable radius of 10 mm (outwards), and can roll 50 mm of its length, changing from the full 15" 16:9 display to a 13.6" 24:9. This is not as impressive as Samsung's rollable demo that grew 5 times its original rolled size.
Samsung Display shows its latest flexible OLEDs at Display Week 2023 and unveils the OLED Sensor Display
Samsung Display demonstrated many OLED technologies at Display Week 2023, which we'll detail below. It seems that the main new technology was the Sensor OLED Display, which is an OLED with an embedded sensor that can perform fingerprint sensing in addition to blood pressure, heart rate sensing and stress level sensing (all from reading the finger), which the company says is the first such display in the world.
The Sensor OLED Display embeds light-sensing organic photodiodes (OPDs) inside the display itself, which allows it to perform the sensing functions all over the display. Samsung explains that as OLED light is reflected differently depending on the contraction and relaxation of the blood vessels inside the finger, the OPD senses the light when it returns to the panel, and converts it into health information.

Samsung set to demonstrate a foldable and slidable AMOLED display
According to a report from Korea, Samsung Display will unveil a new display at CES 2023, which is both foldable and slidable. The display is 8-inch in size when folded, opens up to a 10" display when unfolded, and then can be slided further to 12.4".
The display will be shown in a private booth, which will not be open to the public. It is likely that this display is still at an early stage of development, as there are many challenges such as durability and quality that Samsung will need to overcome. The report suggests, though, that Samsung is ready to soon commercialize such a panel.
