摘要
Wearable electronic devices are being developed because of their wide potential applications and user convenience.Among them,wearable organic light emitting diodes(OLEDs)play an important role in visualizing the data signal processed in wearable electronics to humans.In this study,textile-based OLEDs were fabricated and their practical utility was demonstrated.The textilebased OLEDs exhibited a stable operating lifetime under ambient conditions,enough mechanical durability to endure the deformation by the movement of humans,and washability for maintaining its optoelectronic properties even in water condition such as rain,sweat,or washing.In this study,the main technology used to realize this textile-based OLED was multi-functional nearroom-temperature encapsulation.The outstanding impermeability of TiO_(2)film deposited at near-room-temperature was demonstrated.The internal residual stress in the encapsulation layer was controlled,and the device was capped by highly crosslinked hydrophobic polymer film,providing a highly impermeable,mechanically flexible,and waterproof encapsulation.
