Flexible OLED device and packaging method therefor
2016
The invention provides a flexible OLED device and a packaging method therefor. The flexible OLED device comprises a flexible substrate and an organic light emitting layer, wherein the organic light emitting layer is positioned on the flexible substrate; a first barrier layer is deposited on the organic light emitting layer; the first barrier layer comprises a first inorganic thin film layer and a second inorganic thin film layer; a buffer layer is prepared on the first barrier layer; and a second barrier layer is deposited on the buffer layer. The flexible OLED device is provided with the first barrier layer, the second barrier layer and the buffer layer; the barrier thin film structure is optimized, so that the flexible OLED device has a good water-oxygen-barrier performance; meanwhile, the flexible OLED display is lighter and thinner, and better in bending performance; and in addition, the service life of the flexible OLED display is prolonged.
