A team of researchers at a university in Korea have announced they are moving closer and closer to developing so called ‘bendy’ LED displays.
They are developing technology using inorganic compounds, an example of which, gallam nitride (GaN), has many advantages over traditionally used organic materials and is said to lead to higher quality mechanical, optical and electrical properties contained within the LEDs.
In order to create LEDs through the use of GaN the scientists use a process called ‘free metal organic chemical vapor deposition’, a technique which was originally developed over a decade ago.
Pre-trials are leading to good results, particularly, intense electro-luminescence (electro-luminescence is an optical and electrical phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field: source – Wikipedia.)
The results of the research and development are seen as a major breakthrough in the field of optoelectronics, one which could enable low-cost production on a mass scale. The team, based at the university in the capital Seoul, foresee wearable and flexible LED displays being able for commercial use in the future.
