According to reports, a group of researchers in Canada recently discovered that coating a layer of chlorine atoms on the electrode material of a conventional O LED (organic light-emitting diode) not only improves the luminous efficiency of the OLED, but also greatly simplifies the production process. Reduce production costs and accelerate the application of OLEDs in mainstream flat panel displays and other lighting technologies.
According to the researchers, according to researchers, OLEDs have long been known for their high efficiency, but their performance is significantly reduced rapidly with increased brightness. In order to verify the luminous efficacy of the new OLED, the researchers compared the Cl-OLED with the traditional OLED. It was found that an OLED with a chlorine atom coating can avoid performance degradation after increasing the brightness, and the working efficiency can be more than doubled in the case of very high luminance.
At present, they have developed a technology that uses UV-assisted chlorination to eliminate the use of chlorine, making the entire production process safer and more reliable.
In addition, in order to verify the luminous efficacy of the new OLED, the researchers compared this Cl-OLED with the traditional OLED. It was found that an OLED with a chlorine atom coating can avoid performance degradation after increasing the brightness, and the working efficiency can be more than doubled in the case of very high luminance.
The new technology completely eliminates the expensive coatings used in traditional OLED manufacturing, reducing the cost of production steps and equipment as well as the installation and commissioning of the production line. This effectively reduces the production cost of OLEDs and paves the way for large-scale production of related equipment.
It is understood that chlorine is a chemical element widely found in nature. It can be used for disinfecting tap water, preparing hydrochloric acid, pesticides, plastics, etc. It is widely used in industrial and agricultural production.
Power cables are used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, internal power supply of enterprises, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas.
In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system.
The structure of power cable is relatively simple, which can be divided into conductor, internal and external insulation layer, sheath, armor layer and protective layer. The conductor is mainly made of copper and aluminum, which is used to conduct current. The insulating layer is usually wrapped around the conductor to isolate the conductor and so on. There are various types of power cables. If they are classified according to voltage, they can be divided into low-voltage, medium voltage, high-voltage, ultra-high voltage and ultra-high voltage cables.
Advantages
1. Small land occupation. Generally, it is buried in the soil or laid indoors, in ditches and tunnels. The insulation distance between lines is small, without poles and towers. It occupies less land and basically does not occupy space on the ground.2. High reliability. It is less affected by climatic conditions and surrounding environment, with stable transmission performance and high reliability.
3.It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature and superconducting power cables.
4.Less maintenance work.
5 The possibility of electric shock is low.
