Abstract

The present invention provides a laminated OLED display panel, a manufacturing method thereof, and a display device. The laminated OLED display panel includes: a pixel defining layer, including a plurality of pixel defining regions, and the pixel defining regions intersect to form a plurality of openings; A first charge generation layer, having a first doping type, located on the pixel defining layer and in the opening; a blocking layer, located on a portion of the first carrier transport layer corresponding to the pixel defining region; the second Two charge generation layers, with a second doping type, are located on the barrier layer and the first carrier transport layer not covered by the barrier layer. In the present invention, by setting a barrier layer between the charge generation layers of different doping types, on the one hand, the leakage current in the pixel defining layer is blocked, and the chromaticity impurity caused by light emission in the non-pixel area is prevented; on the other hand, the phase is improved. The problem of crosstalk between adjacent pixels; on the other hand, the material of the barrier layer is convenient and easy to obtain, which saves the processing cost and simplifies the processing technology.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a laminated OLED display panel, a manufacturing method thereof, and a display device including a laminated OLED display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as a current-mode light-emitting device, has the advantages of self-luminescence, fast response, wide viewing angle, and can be fabricated on a flexible substrate, and is widely used in the field of high-performance display. Compared with traditional OLED display panels, laminated OLED display panels can effectively improve brightness and luminous efficiency, and can also achieve high brightness at low power density, thereby avoiding electric field breakdown, thereby prolonging the service life of laminated OLED display panels. [0003] With the continuous improvement of user requirements for display quality, the resolution of laminated OLED display ...
