Embodiment Construction

[0026] As mentioned in the background art, the cracks on the inorganic layer of the film encapsulation layer of the existing flexible touch display panel will affect the display effect of the flexible touch display panel. The inventors found that when the thin film encapsulation layer 12 is evaporated using a mask plate, the mask shadow phenomenon often occurs, such as figure 2 as shown, figure 2 It is another schematic cross-sectional structure diagram of the conventional flexible touch display panel, the inorganic layer 121 is shifted to the non-display area 10b outside the display area 10a or even to the outer edge.

[0027] Since in the prior art, a plurality of flexible touch display panels are fabricated on a larger motherboard, and then the motherboard is cut into independent flexible touch display panels through a cutting process, therefore, the motherboard During the cutting process, the stress generated by the cutting will cause cracks in the inorganic layer 121 a...

Abstract

The invention provides a flexible touch display panel and a manufacturing method thereof, and a flexible touch display device. The flexible touch display panel comprises a flexible substrate, a bufferlayer arranged on the flexible substrate, a light-emitting device layer, and a film package layer; the film package layer comprises an inorganic layer and a first organic layer in alternating arrangement; at least one first groove and a second organic layer covering the first groove are formed on an edge region of a non-display region, and the first organic layer at least penetrates the inorganiclayer, therefore, even if the cutting causes the production of the cracks on inorganic layer at the edge of the flexible touch display panel, since the inorganic layer at the edge is separated from the inorganic layer of the inner side through the first groove, the cracks in the edge inorganic layer cannot extend into the inner side inorganic layer, and cannot extend into other film of the innerside display area, thereby preventing the moisture and the oxygen from entering the display area through the cracks in the inorganic layer and influencing the display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a flexible touch display panel, a manufacturing method thereof, and a flexible touch display device. Background technique [0002] Since the flexible display panel has the advantages of being bendable, rollable and easy to carry, it has become the focus of current research and development in the field of display. Such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of a conventional flexible touch display panel, which includes a flexible substrate 10 , a light emitting device layer 11 and a thin film encapsulation layer 12 on the flexible substrate 10 . The thin-film encapsulation layer 12 includes alternating organic layers 120 and inorganic layers 121 for encapsulating the light-emitting devices in the light-emitting device layer 11 in the display area 10a, so as to prevent water vapor from affecting the light-emitting devi...
