Problems solved by technology

[0003] When folding a flexible AMOLED display device, due to the stress between the film layers, it is easy to cause cracking and delamination of the optically transparent adhesive between the Flexible Cover and the touch panel, especially in the bending area, and in severe cases. The phenomenon that the Flexible Cover breaks makes the bending resistance of the flexible display device poor

Embodiment Construction

[0044] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0045] In the prior art, when the flexible AMOLED display device is folded, due to the stress between the film layers, it is easy to cause cracking and delamination of the optically transparent adhesive between the Flexible Cover and the touch panel, especially in the bending area. In severe cases, the Flexible Cover may break, making the flexible display device less capable of bending.

[0046] At present, the general method in the industry to improve the adhesion between the Flexible Cover and the optically clear glue is to use surface chemical treatment or surface plasma treatment, but these methods are not enough to deal with and completely solve the above-mentioned optical transparency between the Flexible Cover and the touch panel...

Abstract

The invention discloses a flexible display device and a manufacturing method thereof, and belongs to the filed of display technology. The flexible display device comprises a flexible display module and a flexible covering layer, wherein the flexible display module is covered with the flexible covering layer; the flexible covering layer and the flexible display module are adhered together through an optical transparent adhesive tape; and the surface, in contact with the optical transparent adhesive tape, of the flexible covering layer is rugged. Through the technical scheme, the bending resistance of the flexible display device can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] Existing flexible AMOLED (Active Matrix Organic Light Emitting Diode) display devices usually include film layers such as a Flexible Cover (flexible cover layer), a circular polarizer, a touch panel, a display panel, and a bottom diaphragm stacked in sequence, wherein , the Flexible Cover and the touch panel are glued together through optically clear adhesive (OCA), and the touch panel is glued together with the display panel through optically clear glue. [0003] When folding a flexible AMOLED display device, due to the stress between the film layers, it is easy to cause cracking and delamination of the optically transparent adhesive between the Flexible Cover and the touch panel, especially in the bending area, and in severe cases. The breakage of the flexible cover makes the b...
