Abstract :
The luminous efficiency of OLEDs with a MQW structure have been investigated and improved. The efficiency of OLEDs with the quantum well structure is 90% higher than the standard device. We suggested that the improvement due to the MQW structure confine carrier in each well without decreasing the mobility of electrons.
