Problems solved by technology

[0003] The display panel with FMLOC structure has many inorganic film layers. Once the internal water vapor cannot be discharged smoothly, it is easy to form bubbling inside the film layer (commonly known as bubble defect). The bubbling will cause the corresponding film layer to separate, and in severe cases, it will cause film layer wrinkles. or peeling, or even cause bad touch

Abstract

The invention provides a preparation method of a display panel, the display panel and a display device. The preparation method comprises the steps of forming an inorganic packaging layer on a drivingbackboard through employing a vapor deposition method, and enabling the inorganic packaging layer to comprise a main packaging layer covering a display region and a part of a peripheral region, and apermeation layer extending from the main packaging layer to a direction far away from the display region, forming an inorganic layer at one side, deviating from the driving backboard, of the inorganicpackaging layer, and enabling the inorganic layer to comprise a first inorganic layer covering the main packaging layer and a second inorganic layer extending from the first inorganic layer to a direction far away from the display area, and synchronously etching and removing the second inorganic layer and the permeation layer by adopting the same mask. Therefore, the permeation layer can be removed, the problem of bubbling caused by the permeation layer is solved, and good performance of the FMLOC touch display panel is guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a method for preparing a display panel, a display panel and a display device. Background technique [0002] FMLOC (Flexible Multi-Layer On Cell) design is currently the mainstream in the OLED touch display field, especially in the mobile phone screen industry where it is the main process direction. FMLOC design refers to making a metal grid electrode layer on the package driver backplane of the display panel, so as to perform touch control without external TSP (Touch Screen Panel, touch screen). This process can reduce the thickness of the screen, improve the yield rate and reduce the cost. . [0003] The display panel with FMLOC structure has many inorganic film layers. Once the internal water vapor cannot be discharged smoothly, it is easy to form bubbling inside the film layer (commonly known as bubble defect). The bubbling will cause the corresponding film layer to...
