摘要： A method for encapsulating an OLED device includes providing a substrate on which a barrier layer is formed; forming a surface active layer that includes multiple strips on the barrier layer; forming buffer strips on the surface active layer to correspond, in a one-to-one manner, to the strips of the surface active layer; and allowing the buffer strips to spread over the substrate and cover the barrier layer to form a buffer layer. The surface active layer that is sandwiched between and in direct contact with the barrier layer and the buffer layer includes a material that creates a hydrogen bond with a material of the buffer layer to enhance bonding therebetween.

摘要： A flexible OLED includes a substrate, an anode, a hole transport layer, a stopper chamber, an electron transport layer, a cathode, and a cover stacked in sequence. The stopper chamber is filled with a light emitting layer. Surfaces of the hole transport layer and the electron transport layer that face each other are provided with free H+ ions that exchange with H atoms contained in a material of the light emitting layer to connect the light emitting layer to the surfaces of he hole transport layer and the electron transport layer.
