The property of encapsulation using thin film multi layer for application to organic light emitting device

We have developed a thin lm multi layer as encapsulation method for OLED. The characteristics of the OLED encapsulatedwith thin lm multi layer showed the similar OLED with metal cap encapsulation. The IVL test of OLED panels with thin lmmulti layer showed that the brightness is 1000 cd/m2 with the eciency of 7.6 lm/W at the 7 V and it took more than 2000 h for thebrightness to fall from 1000 to 500 cd/m2. This result shows that the device with thin lm multi layer has similar level of brightnessand eciency and more than 95% of lifetime compared to device with metal can encapsulation. Thus, we can conrm that thin lmmulti layer has an eect as encapsulation process to protect organic light emitting device. Also, thin lm multi layer for the pro-tection of organic light emitting device simplies passivation process, makes less than 0.8 mm thick device and is also applicable towide and exible display.
