Canada's use of chlorine atom coating to improve OLED light efficiency technology

Recently, Canadian researchers have found that coating a layer of chlorine atoms on the electrode materials of traditional OLEDs not only improves the luminous efficiency of OLEDs, but also greatly simplifies the production process, reduces production costs, and will accelerate the display of OLEDs on mainstream flat panels. And other lighting technology applications.

Recently, Canadian researchers have found that coating a layer of chlorine atoms on the electrode materials of traditional OLEDs not only improves the luminous efficiency of OLEDs, but also greatly simplifies the production process, reduces production costs, and will accelerate the display of OLEDs on mainstream flat panels. And other lighting technology applications.

According to the researchers, the application of this technology is very simple. It is only necessary to add a one-atom-thick chlorine coating to the indium tin oxide (ITO, also called tin-doped indium oxide) electrode material of the current standard industrialized OLED. . This new technology not only improves the electrical performance of traditional OLEDs, but also eliminates the need for many expensive coatings that are used in large quantities on traditional OLEDs.

At present, they have developed a technology that assists chlorination through UV rays, which can eliminate the use of chlorine gas and thus make the entire production process safer and more reliable.

In addition, in order to verify the luminous efficacy of the new OLEDs, the researchers compared the Cl-OLEDs with traditional OLEDs. As a result, it has been found that an OLED with a chlorine atom coating can avoid a drop in performance after the brightness is raised, and the work efficiency can be more than doubled when the light emission luminance is very high.

The new technology completely eliminates the expensive coatings used in traditional OLED manufacturing, reducing the cost of installation and commissioning of production steps and equipment and production lines. This effectively reduces the production cost of OLEDs and paves the way for large-scale production of related equipment.
