We studied the light extraction efficiencies of white organic light-emitting diodes with a light-out-coupling layer by simulations and experiments. The light extraction efficiencies estimated by the simulation were confirmed to agree well with those

We demonstrated that a light-extraction efficiency of OLEDs was evaluated accurately by fitting an external quantum-efficiency to a calculated optical-mode. An internal quantum-efficiency of 62.6% was obtained in the green OLED with thick electron tr

We achieved operationally stable white OLEDs with an EML fabricated using a self-layered technique. LT50 of more than 10khr at an initial luminance of 1000cd/m2 was obtained by 1) suppressing exciplex formation between EML and ETL, 2) preventing Li d

We achieved a highly efficient white organic light emitting diode with a single emitting layer consisting of three kinds of dopants. The emitting layer was fabricated with a one-step solution coating process. A maximum power efficiency of 70 lm/W was

Color shift and gray scale reversal for very large viewing angles are analyzed theoretically for in-plane switching. It follows that the color shift depends on the change of the effective birefringence dΔn, whereas gray scale reversal depends on the

Complete suppression of color shift in in-plane switching mode liquid crystal displays (LCDs) has been realized. The LCDs have a multidomain structure obtained by unidirectional rubbing and use of zigzag electrodes. The design concept and performance
