Recently, it is reported that the Korean research team has created a new type of LED display through a two-stage replacement process to create a new type of structure. The components are driven steadily, and the luminous efficiency is increased by more than three times. This indicates high brightness and low power consumption. The display lighting system has taken a step forward.
The display industry and the semiconductor industry are also known as the two major industries in Korea. As the main medium for the transmission of images, the importance of the display is self-evident, and the performance indicators such as low power consumption, light weight, high image quality, and flexibility are also The general trend of development, so the research team mainly for the new generation of display screens and quantum dot light-emitting elements of the study.
Dr. Huang Daojing, Ph.D., Optoelectronic Materials Research Team, Korea Institute of Science and Technology (KIST), and Dr. Cui Yuan-Ju, Ph.D., of the Future Comprehensive Technology Research Center, used nanoparticle generation of high-molecular materials PEIE and zinc oxide (ZnO). The double-layered structure of the "injection layer" and "transport layer" has maximized the stability and luminous efficiency of the components, thereby developing a quantum dot LED display.
The polymer material PEIE is inexpensive and is an environmentally friendly material. If it is in contact with metals or conductive organic substances, the work function of each substance can be reduced, thereby playing the role of the surface modification material. Indium tin oxide (ITO) has a relatively high work function of 4.8 eV and is therefore mainly used as an anode material. After coating with PEIE (surface modifier), the work function is reduced to 3.08 eV and becomes a cathode use. The transformed structure allows the stability of the components to be improved.
After the injection layer and the transport layer are formed, the polymer material PEIE only functions as an injection layer and blocks the externally injected holes, and then the electron-transporting transport layer will fail. In order to solve this problem, the research team at PEIE The surface was coated with zinc oxide nanoparticles and acted as an electron transport layer. Through this design concept, quantum dot LED displays were finally successfully developed. This research result has been published in the international academic magazine Scientific Reports. 10th online edition.
Dr. Huang commented: “The prices of raw materials such as PEIE and zinc oxide are not high, and they are rich in reserves on the earth, and their sources are stable. The components of the electrode conversion structure are very stable, not only prolonging the life of the display, but also can be used for solar energy. The light sensor of the battery; The quantum dot LED display screen is still in the trial production stage. Compared with the existing display screen, the color purity and the picture quality have been significantly improved. It is expected to replace the OLED display in the next 5 to 10 years. , ultimately achieving mass commercial production."

Scientific and technological developments is well known, as the representative highlighted the large display, LED display has almost outdoor display of the status of the king, usually defined as installed outside buildings, at the top of the column large-size display products. In the past two years, the small-pitch LED display technology has been widely used and recognized. Some industry analysts believe that the application of digital signage advertising machines will become the best battlefield for small-pitch LED displays. With the continuous expansion and upgrading of the LED market, the requirements for LED display technology are also increasing. The fierce market competition has also made LED technology an embodiment of corporate competitiveness.
