Foldable screens haven’t even become really affordable yet, but the industry is already looking for more innovations in the display department for years to come. Stretchable displays should be among the next trends, and there are already commercially viable options out there.

Samsung claims to have proven for the first time that a stretchable screen is not only ready to be used in wearable devices, but has shown some of its usefulness. South Korean researchers would have created a free-form visor, which can be stretched in any direction, “like a rubber band”, and therefore can take whatever shape is needed.

More than that, they demonstrated that such a display could be connected to existing semiconductors, and with that they could measure a person’s heartbeat in real time. A kind of smart bracelet was used in the demonstration, in a wearable that, according to the researchers, can take the shape of each arm in which it is placed.

It’s not the first time that a stretchable screen has been demonstrated: FlexPai maker Royole demonstrated a similar display during Display Week 2021. In the case of the Chinese company, a micro-LED screen that stretches and stretches to the market was announced to the market. 130%.

Samsung Stretch Screen

Called “elastic electronic skin” by the researchers, the prototype can grow up to 30% without losing performance. The component combines extensible organic LED display (OLED) with a photoplethysmography (PPG) sensor. Tests have shown that the screen can be stretched more than a thousand times and still function normally.

The prototype even measured a volunteer’s heart rate accurately, and was still able to pick up the heart rate signal with strength up to 2.4 times greater than a fixed silicon sensor, according to the researchers. To avoid degradation over time, they replaced the plastic parts with an elastomer.

In addition to devices to measure heart rate, researchers are considering creating stretched screens to measure oxygen saturation, electromyography, and blood pressure. There are still some challenges to overcome, but they believe that it is now possible to create commercial devices with the new screen.

There was no forecast for the first products to reach stores.
