One or more embodiments of this specification provide a method for fabricating an array substrate, an array substrate, and a display panel; the fabrication method includes: forming spacers on a base substrate; disposing an anode material, and patterning the anode material process, forming an anode layer and a protective layer covering the isolation pillars; through a patterning process, removing the protective layer to expose the isolation pillars. In the solution provided in this specification, the anode layer and the isolation column are respectively formed in different manufacturing processes, and when the anode layer is formed, the anode material is used to form a protective layer covering the isolation column, and the isolation column and the silver ions are formed by the protective layer. Isolation can effectively prevent the formation of silver monomers and avoid the formation of dark spots in the effective display area, thereby ensuring the display quality.
Description
technical field [0001] One or more embodiments of this specification relate to the field of display technology, and in particular, to a method for fabricating an array substrate, an array substrate, and a display panel. Background technique [0002] With the development and upgrading of display technology, organic electroluminescence display (Organic Electroluminance Display, referred to as OLED) has gradually become a display field due to its characteristics of self-luminescence, high brightness, high contrast, low operating voltage, and the ability to make flexible displays. mainstream products. [0003] In order to realize the image acquisition function, refer to figure 1 , the OLED display panel needs to open an opening area in the active display area (Active Area, AA area for short) to set the image acquisition component. However, in the display panel manufactured by the related art, there are generally many dark spots (also called dead spots) in the position of the A...
