preparation example Construction

[0054] In the method for preparing a flexible display panel provided in this embodiment, two flexible buffer regions with different bending strengths are formed on the base substrate. In the display device, electronic components with low bending resistance are formed at the bending strength In the lower flexible buffer zone, the stress on the area with weaker bending strength will be dispersed to the area with stronger bending strength, which is beneficial to reduce the stress change in the area with poor stress during bending deformation and reduce wear.

[0055] Figure 1 to Figure 2 For an embodiment of the preparation method of the flexible display panel provided by the present invention, please refer to Figure 1 to Figure 2 , a method for preparing a flexible display panel proposed by an embodiment of the present invention, including:

[0056] S10, forming a flexible substrate with a first flexible buffer region having a first bending strength and a second flexible buff...

Abstract

The invention relates to a flexible display panel, a flexible display device and a preparation method thereof, and relates to the field of flexible display technology. The main technical problem to be solved is that the electronic components with low bending resistance of the flexible display panel are prone to wear and tear. The method for manufacturing a flexible display panel includes: forming a first flexible buffer area with a first bending strength and a second flexible buffer area with a second bending strength on a base substrate, the first bending strength being greater than the first bending strength Two bending strength; forming a display device on a flexible substrate. In the display device, the electronic components with low bending resistance, the perforated area and the channel area with poor flexible stress are formed in the second flexible buffer area, and the stress on the second flexible buffer area with weak bending strength will be distributed to the bending area. The first flexible buffer area with stronger strength is beneficial to reduce the stress change suffered by the display component in the weaker stress area (second flexible buffer area) during bending deformation and reduce wear.

Description

technical field [0001] The invention relates to the field of flexible display technology, in particular to a flexible display panel, a flexible display device and a preparation method thereof. Background technique [0002] Organic Light Emitting Display (OLED) has excellent performances such as low power consumption, high saturation, wide viewing angle, thin thickness, and flexibility, and has gradually become the mainstream in the display field. [0003] The preparation process of traditional flexible display panels is as follows: a uniform flexible substrate is bonded and formed on a rigid substrate, and then thin film transistors and display electronic components are formed on a uniform flexible substrate, and finally the flexible substrate is separated from the rigid substrate. , a flexible display panel can be prepared. [0004] The inventor finds that there are at least the following problems in the prior art: [0005] During the bending of the flexible display panel...
