Phone Displays Could Soon Stretch to Become Tablet, Wrap around the Wrist like Watch

When mobile phones were originally introduced, they were large and unsightly. After then, other researchers focused on making them more compact and appealing. People progressively became more accepting of the technology since it allowed them to converse while on the move. Since then, there have been significant improvements to meet the needs of the consumers. A group of academics has devised a means to make the mobile phone versatile - you can fold it up and store it in your pocket or wallet, expand the screen to make it a tablet, or wrap it around your wrist like a watch, according to the researchers.

Researchers at Washington University's McKelvey School of Engineering have enabled the next stage in the development of digital displays. The researchers, led by Chuan Wang, Assistant Professor in the Preston M. Green Department of Electrical & Systems Engineering, have discovered a new material that combines the best of both technologies — LEDs and OLEDs — as well as a novel fabrication method that involves an inkjet printer.

Their findings were reported in the Advanced Materials journal. To make a specific form of crystalline material known as an organometal halide (Omh) perovskite, the researchers employed an inkjet production process rather than the typical spin art method. The display is bendable thanks to its organic-inorganic combination. The Perovskite light-emitting diodes (PeLEDs) can then be retrieved from there. "We assumed we could utilize an inkjet printer since it arrives in a liquid state," Wang said in a EurekaAlert release. Inkjet fabrication also saves resources by depositing perovskite just where it is needed.

"The procedure is substantially quicker, taking only 25 minutes instead of 5 hours," Wang explained. "Imagine a gadget that begins with the size of a cellphone but expands to the size of a tablet." These PeLEDs might represent the start of a new era in electronics. They might light up walls or even show the current day's newspaper. Wearable gadgets, such as a pulse oximeter that measures blood oxygen, can be made using them. They can also enable manufacturers to print flexible gadgets, which is very intriguing.
