Thanks to CTOnews.com netizen Xiao Zhan for the clue delivery! CTOnews.com April 20 news, my friend of CTOnews.com, have you ever thought that one day all kinds of information will be displayed on your clothes, watch or skin? It sounds like a plot from science fiction, but the latest scientific research brings the fantasy closer to reality. Researchers at the University of Chicago in the United States have developed a new type of OLED screen that can stretch to twice the length while still maintaining a clear image. This super-flexible OLED screen provides new possibilities for future wearable electronic devices and health sensors.

OLED is the abbreviation of organic light-emitting diode, which is a technology that uses organic molecules to emit light. OLED screens are more energy efficient, brighter, thinner and softer than traditional LED and LCD screens. At present, OLED screen has been widely used in televisions, computers, mobile phones and game consoles and other devices, is one of the most advanced electronic display technology. However, another problem with existing OLED screens is that their materials are fragile and do not adapt well to stretching and bending. This limits their use in wearable and implantable devices.

To solve this problem, researchers at the University of Chicago used the knowledge of molecular engineering to redesign the material of the OLED screen. They inserted some hydrocarbon chains between OLED molecules, making the whole chain more flexible and flexible. They also used a method called thermally activated delayed fluorescence (TADF), which allows organic molecules to efficiently convert electrical energy into light energy. After many calculations and experiments, they finally created a new type of OLED screen that still glows normally and displays a clear image when stretched to more than twice its original length.

The research results have been published in the journal Natural Materials and have attracted the attention of the industry. The researchers say the super-flexible OLED screen will revolutionize the next generation of wearable electronic devices and health sensors. "this is the kind of material you need to eventually develop a really soft screen." "this work is really fundamental, and I expect it to give birth to a lot of technologies that we haven't thought of yet," said DePablo, one of the leaders of the research team. "

The researchers say they will also continue to improve the new OLED screen, increasing its color range and performance efficiency, and bringing it to the level of existing commercial technology. "our goal is to eventually reach the same or higher level as the existing state-of-the-art OLED display technology." Said another head of the research team.
