If you decorate a new house, you can cut the different colors of the OLED (Organic Light Emitting Diode) material into the shape you want, and then attach it to the wall or the roof and then power it on, so that you have a colorful and distributed Uniform wall lighting. According to information provided by General Electric, the company announced on March 19 that a major breakthrough in OLED manufacturing technology will make this vision a reality.
This technology is the world's first successful use of roll-to-roll "spin coating" to produce OLEDs. This technology will greatly reduce the production cost of OLED and other high-performance organic electronic products, and realize a leap in lighting mode. It is no longer a luxury to let flat lighting enter commercial applications.
OLED lighting is a key technology developed by major companies around the world. Although it is technically achievable, because OLEDs cannot be mass-produced, flat-panel lighting can only be left in the lab because of the high cost. Anil Dag, General Electric's senior technology project manager for organic electronics, said that researchers have long dreamed of producing OLEDs by "roll-to-roll" spin-drying like printing newspapers. Now we have proved that this is achievable. Thereby meeting the low cost requirements of lighting commercial applications.
Dr. Chen Xiangli, President of GE China R&D Center, said: "The era of commercial OLED lighting is coming soon. This low-cost spin coating process will break the barrier that currently hinders the large-scale application of OLED lighting. Architects will have more and more 'modern 'The design choices, many of our living habits and concepts will also change."
The OLED device is composed of one or more layers of a semiconductor organic film sandwiched between two electrode plates, and the organic film can emit strong light after being energized. As the next-generation planar distributed solid-state light source, it has the characteristics of being light and bendable and high-performance, and can be used in many home and commercial fields such as lighting systems and flat displays. In the future, not only the "wallpaper lights" that are covered with walls and ceilings will replace traditional lamps, but the computer screens will also be rolled into a tube and carried around. As a high-efficiency light source, this technology also has the potential to greatly improve luminous efficiency and save energy. The left picture shows an OLED using a spin coating process.
