OLED life has been enhanced to achieve life is no longer OLED promotion problems?
Researchers at Kyushu University in Japan have managed to substantially increase the life of TADF OLED emitters by about eight times. This is achieved by a simple modification of the device structure by placing two thin (1-3 mm) layers of Liq, a lithium-containing molecule, on either side of the hole-blocking layer. TADF devices used by researchers have a life expectancy of only about 85 hours (LT95). This is the use of "extreme brightness" to speed up the test. With new designs and some additional modifications, equipment life was increased to 1300 hours, almost 16 times the initial equipment life. However, the researchers said such performance still can not meet the commercial application. And just at the end of 2015, Taiwan's Industrial Technology Research Institute (ITRI) has developed a new OLED device architecture that dramatically increases the life of RGB OLED displays. Known as a plasma-coupled organic light-emitting diode (PCOLED), this new structure offers 27 times longer lifespan than traditional blue / red-green fluorescent structures.
Galvanized Steel Sheet & Plates, are intended for use where greater corrosion protection is required without painting. A lower cost alternative to stainless steel, galvanized sheet and plates have a rust free protection for up to 30 years, while maintaining strength with a durable surface coating. Our company stocks many sizes in precut sizes, full mill sizes or we can hot dip virtually any size and quantity required for your welding or construction project.
Galvanized steel Sheet coil has a light weight, beautiful and good anti-corrosion performance, can be directly processed. Is mainly used in construction, shipbuilding, automobile manufacturing, machinery manufacturing, furniture home appliance industry, electrical and automation industry. Efficient construction, save energy and protectenvironment, prevent pollution etc.

Hot-dip galvanized sheet is made by immersing the steel sheet in a molten zinc bath at about 500 °C to attach a zinc layer to the surface. This is the continuous galvanizing process. It will form a protective zinc layer on the surface so that it has good paint adhesion and weldability. It is the most widely used and cost-effective method to prolong the service life of steel sheets.
Electro-galvanized Steel Sheet
Electro-galvanizing, also known as cold galvanizing, uses electrolysis to form a uniform and dense layer on the surface of the metal. The anti-corrosion zinc layer can protect steel parts from oxidation corrosion. Also, it can meet decorative purposes. But the zinc layer of the electro-galvanizing steel sheet is only 5-30 g/m2. So its corrosion resistance is not as good as hot-dip galvanized sheets.
