Embodiment Construction

[0053] In the actual process, before forming the touch electrode layer, it is necessary to form a layer of touch barrier layer on the encapsulation layer. After forming the encapsulation layer, the edge area of ​​the OLED display A wet cleaning process will be performed before the control barrier layer. During this process, the exposed flat layer will absorb moisture. After the touch barrier layer is formed, when the high temperature process is performed, the moisture in the flat layer will be blocked by the touch barrier layer. , and cannot be discharged, resulting in peeling between the touch barrier layer and the flat layer, and even the OLED display panel is scrapped due to the damage of the film layer.

[0054] Based on this, in order to solve the problem of easy peeling between the touch barrier layer and the flat layer in the related art, the embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device.

Abstract

The invention discloses a display panel and a manufacturing method thereof and a display device. The display panel comprises: a substrate; a flat layer which is arranged at one side of the substrate;a retaining wall which is positioned in a peripheral area, wherein the retaining wall is positioned on one side, deviating from the substrate, of the flat layer and is of an annular structure surrounding a display area; a packaging layer which covers the display area and at least part of the peripheral area; a touch barrier layer which is located on the side, deviating from the substrate, of the packaging layer; and a water blocking layer which is located in the peripheral area, wherein the water blocking layer is located between the flat layer and the touch barrier layer, the flat layer and the touch barrier layer extend to the side, away from the display area, of the retaining wall. The water blocking layer located between the flat layer and the touch barrier layer is arranged in the peripheral area, in the wet cleaning process before the touch barrier layer is formed, due to the fact that the water blocking layer covers the flat layer located in the peripheral area, the phenomenon that the flat layer absorbs water can be relieved, and the risk of stripping between the touch barrier layer and the flat layer is effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and is considered to be the next generation display technology. Among them, the touch integrated flexible technology can set the touch electrode layer inside the OLED display panel to realize the touch function, making the OLED display panel lighter and thinner, and simplifying the manufacturing process of the OLED display panel, so that the production cost is significantly reduced. Therefore, it has gradually become the mainstream touch technology. Contents of the invention [0003] Embodiments of the present invention provide a display panel, a manufacturing method thereof, and a display device to solve the problem of eas...
