Flexible display panel, flexible display device and preparation method of flexible display panel

Abstract

The invention relates to a flexible display panel, a flexible display device and a preparation method of the flexible display panel and belongs to the flexible display technical field. The invention mainly aims to solve the proneness of the low-bending-resistance electronic components of a flexible display panel to being worn. The preparation method of the flexible display panel includes the following steps that: a flexible substrate provided with a first flexible buffer region having first bending strength and a second flexible buffer region having second bending strength is formed on a substrate, wherein the first bending strength is greater than the second bending strength; and a display device is formed on the flexible substrate. Electronic component with low-bending-resistance electronic components as well as a punched region and a channel region which have poor flexible stress in the display device are formed in the second flexible buffer region; and stress applied to the secondflexible buffer region with weak bending strength is dispersed to the first flexible buffer region with strong bending strength, and therefore, the reduction of the change of stress borne by display components in the poor stress region, namely, the second flexible buffer region, can be benefitted, and wear can be reduced.

Description

technical field [0001] The present 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 displ...
