Quantum dot printing OLED device and manufacturing method thereof

The invention relates to the technical field of OLED display, in particular to a quantum dot printing OLED device which specifically comprises an anode substrate layer, a hole transport layer, a functional film layer, a hole barrier layer and a metal cathode layer, during manufacturing, an OLED is prepared in a mode of combining photoetching, ink jet printing and vacuum evaporation, and meanwhile inorganic salt halide is introduced into quantum dots, so that the quantum dot printing OLED device is manufactured. By means of the method, the influence of surface tension on quantum dot film forming can be reduced, the uniformity of film forming in pixels of a printed OLED device is improved while the charge transfer capacity is improved, and then the performance of the printed OLED device is improved. 本发明涉及OLED显示技术领域，具体涉及一种量子点印刷OLED器件，具体包括阳极基板层、空穴传输层、功能膜层、空穴阻挡层和金属阴极层，制作时，使用光刻、喷墨印刷及真空蒸镀相结合的方式制备OLED，同时在量子点中引入了无机盐卤化物，使量子点的化学基团与无机盐卤化物反应钝化，形成具有保护作用的功能膜层，该方法可以减少表面张力对量子点成膜的影响，在提高电荷传输能力的同时，提高印刷OLED器件像素内成膜的均匀度，进而提高印刷OLED器
