Abstract

The invention discloses a preparation method of a display panel, the display panel, and a display device. The preparation method of the display panel comprises steps that a substrate is provided; a first electrode layer is disposed on the substrate; a first transparent electrode layer is disposed on the first sub-pixel region of the side of the first electrode layer away from the substrate by adopting a photolithography technology; second transparent electrode layers are disposed on the side of the first transparent electrode layer away from the substrate and the second sub-pixel region of the side of the first electrode layer away from the substrate; pixel definition layers are disposed between adjacent sub-pixel regions; an organic light-emitting structure layer is disposed on the second transparent electrode layers, a first electrode layer of a third sub-pixel region, and the pixel definition layers, and at least comprises an organic light-emitting layer; a second electrode layer is disposed on the side of the organic light-emitting structure layer away from the substrate. A problem of difficulty in realizing simultaneous enhancement of red light, green light, and blue light emitted by the display panel is improved, and the preparation technology of the display panel is simplified.

Description

technical field [0001] Embodiments of the present invention belong to the field of display technology, and relate to a method for preparing a display panel, a display panel, and a display device. Background technique [0002] The technologies for realizing the colorization of Organic Light-Emitting Diode (OLED) include two mainstream technologies, that is, micro-cavity effect RGB pixel independent light-emitting technology, and white light-emitting materials combined with color filter technology. [0003] Micro-cavity effect RGB pixels need to use precise metal shadow mask and pixel alignment technology to prepare red, green and blue primary color light-emitting centers of micro-cavity effect to achieve colorization. The shadow mask method is difficult to ensure the positioning accuracy of sub-pixels, and it is relatively difficult to realize a display panel with high pixel density. Moreover, the precision metal shadow mask is expensive, which will lead to an increase in cos...
