The first transparent graphene electrode OLED display came out

Flexible, clear and extremely robust graphene is an outstanding conductor of heat and current, making it a popular material for the next generation of electronic devices. In this regard, researchers first used graphene to make OLED electrodes. This can lead to a series of new components, including better touch screens and more efficient solar cells. The electrode attached to the OLED (organic light emitting display) was about 2 cm x 1 cm (1/2 inch x 1/4 inch) and was fabricated using a chemical vapor deposition (CVD) process where methane and hydrogen were pumped into the vacuum chamber and the copper plate was heated To 800 ° C (1,472 ° F). Here, a chemical reaction takes place between the two gases, and when methane dissolves into the copper, it forms graphene atoms on the surface. Once the layer is fully formed, the entire device is allowed to cool, a protective polymer sheet is applied, and copper is then chemically etched to reveal the monatomic layer of pure graphene. Beatrice Beyer, Ph.D., Ph.D., Ph.D., of organic electronics, e-beam and plasma technology at Fraunhofer, said: "This is a real breakthrough in extremely demanding materials research and integration. Although this is not the first flexible display to use graphene in its construction , But it introduced OLED technology for the first time and took a big step toward a full color screen and quick response times. " Graphene is widely used from conductors to supercapacitors, solar cells and a host of other electronic devices. Displays made of such materials improve the longevity, durability and usability of photovoltaic cells, wearable devices, flexible textiles and medical devices , This research may lead to rapid development in these fields in the near future.
