Samsung Display announced on Tuesday that it has developed a display that can be rolled and unrolled vertically, much like a scroll called a “Rollable Flex”. This is one of the many concepts that the company is going to exhibit at SID Display Week 2023, an annual display industry conference being held in Los Angeles from May 23 to 25.
Currently, Rollable Flex stands 49mm in length but can be unrolled to extend to 254.4mm using an O-shaped axis. This gives the display multiple applications, both when rolled and unrolled. When rolled, it can be used as a portable screen such as for a laptop or tablet while you can extend it to a monitor-sized display when unrolled.
Another new display unveiled at the conference is the Sensor OLED. As the name suggests, this is an OLED display except it can recognise fingerprints anywhere on the screen’s surface, instead of having a pre-designated area like we see in current implementations.
Instead of using fingerprint reading modules placed under the screen as we see in current consumer applications, Samsung has instead used light sensors that cover the whole screen during the display manufacturing process itself.
These sensors then read the OLED light reflected from the contraction and relaxation of the blood vessels inside your fingers when touched and convert them to health information including heart rate, blood pressure and stress level.
Previously announced displays from other conferences will also be shown off. These include the Flex Hybrid, a display that can both be folded and slid as well as Flex In & Out, a display which you can fold both inwards and outwards by a full 360 degrees. Last but not last, Samsung Display will also be showing off its latest 77-inch QD-OLED display aimed at the high-end TV market with a reported brightness of 2,000 nits.
