Problems solved by technology

However, when the flexible display is bent, it is easy to cause damage to the buffer layer (for example, the buffer layer produces cracks at the bending point), resulting in the problem of disconnection of the traces formed on it.

Abstract

A flexible display panel and a method of fabricating the same are provided. The flexible display panel has a bending region, a first region, and a second region. The flexible display panel includes a buffer layer and a pixel unit. The buffer layer is disposed on a flexible substrate. The pixel unit is disposed on the buffer layer of the first region. The buffer layer has a dopant, wherein the concentration of the dopant in the bending region is [M]; the concentration of the dopant in the first region is [M]1, and [M]1 / [M] > 10 or [M]1 / [M] < 0.1.

Description

technical field [0001] The present invention relates to a display panel and its manufacturing method, and in particular to a flexible display panel and its manufacturing method. Background technique [0002] With the widespread application of portable displays, the development of flexible displays is becoming more and more active, so as to achieve the purpose of displaying on different curved surfaces. Generally speaking, the substrates used in flexible displays are flexible substrates. However, flexible substrates do not perform well in blocking water and oxygen. After long-term use, moisture or oxygen in the environment will enter the flexible substrate. The inside of the flexible display makes the flexible display prone to short circuit and cause abnormal display. [0003] In order to improve the water and oxygen barrier performance of the flexible substrate, the flexible substrate can be composed of a flexible substrate and a buffer layer. However, when the flexible di...
