Flexible OLED device and packaging method therefor

一种柔性oled器件及其封装方法

Abstract

本发明提供一种柔性OLED器件及其封装方法,柔性OLED器件包括柔性基板、有机发光层,所述有机发光层位于柔性基板之上,在所述有机发光层上沉积有第一阻隔层,所述第一阻隔层由第一层无机薄膜和第二层无机薄膜组成,在所述第一阻隔层上制备有缓冲层,在所述缓冲层上沉积有第二阻隔层。本发明设有第一阻隔层和第二阻隔层,还设有缓冲层,本发明优化了阻隔薄膜结构,具体良好的水氧阻隔性能;使柔性OLED显示器更轻薄、弯折性能更好,而且延长了柔性OLED显示器的使用寿命。
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.
