Abstract
The invention relates to a flexible organic electroluminescent device as well as a manufacturing method thereof and an organic light-emitting display device, wherein the flexible organic electroluminescent device comprises a first base plate and a second base plate, an organic electroluminescent structure and an encapsulation layer are arranged on the first base plate in sequence. The flexible organic electroluminescent device is characterized in that a plurality of first water-oxygen barrier surrounding dams, which are arranged at the periphery of the encapsulation layer, for preventing water and oxygen from invading the organic electroluminescent structure are arranged between the first base plate and the second base plate in a spaced manner. The flexible organic electroluminescent device has the beneficial effects that the flexible organic electroluminescent device is ensured to prevent water-oxygen invasion due to the setting of the water-oxygen barrier surrounding dams.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a flexible organic electroluminescence device, a manufacturing method, and an organic light-emitting display device. Background technique [0002] Flat panel display technology has developed rapidly in the past ten years, and great progress has been made in terms of screen size and display quality. After continuous efforts, the performance of all aspects of LCD has reached the level of traditional CRT, and there is a tendency to replace CRT. [0003] With the continuous expansion of the production of flat panel display products, the competition among various manufacturers is becoming increasingly fierce. While continuously improving product performance, manufacturers are also making continuous efforts to reduce product production costs, thereby enhancing market competitiveness. [0004] OLED display devices are considered to be dream displays in the future display product mark...
