Recently, scientists in Germany and Spain have made new breakthroughs in OLED technology, and found a way to make OLED screens more energy efficient and longer lasting.
We know that OLED screens are thinner, lighter, and brighter than LCDs. However, the shortcoming of OLED is that its life is shorter. The scientists' improvements did not make screens with new organic polymer materials, nor did they redesign the screen structure, but simply changed the OLED manufacturing process.
It turns out that when the raw material is deposited on the substrate, it is only necessary to increase the temperature to improve the OLED screen. When the temperature reaches a certain condition, the material changes from a glassy state to a rubbery state. For many organic materials, this temperature is about 100 degrees Celsius. Researchers can create "ultra-stable glass" by heating the polymer to a temperature of 80-90% of the conversion temperature.
The researchers tested with four commonly used phosphorescent emitters and found that life was extended by 15% and energy savings by 15%. Next, researchers will test new technologies with more OLED materials. Then it depends on whether the heating technology can be used in the manufacturing process without adding too much cost.
