New Mitsubishi OLED Material Promises Development of More Efficient, Less Costly Display Screens

Mitsubishi Chemical today announced that it has developed an Organic Light-Emitting Diode device with the highest efficiency in the world in its new blue phosphorescence OLED material.

The new OLED material, which can be produced by a lower-cost, wet-coating process, is expected to open the way to the development of a new class of large flat-panel displays.

The newly developed OLED device employs MCC's own blue phosphorescence host material (wet-coating type), hole blocking material, and hole injection material to optimize the design of a device to achieve the current efficiency of 30 cd/A at the intensity of 100 cd/m2 (external quantum efficiency: 13%), more than twice that of conventional blue wet-coating type OLEDs.
