Abstract

The invention discloses a preparation method of a flexible screen and the flexible screen. The preparation method of the flexible screen comprises the following steps: providing a flexible substrate; pre-stretching the flexible substrate through an external force; preparing a display driving array on the pre-stretched flexible substrate; and removing the external force to enable the flexible substrate and the display driving array to shrink at the same time so as to obtain the flexible screen. The flexible substrate is pre-stretched under the effect of external force in advance, the display driving array is prepared through deposition after pre-stretching, then the external force is removed, the flexible substrate and the display driving array are integrally shrunk again, and the prepared display driving array can be prevented from being broken under the condition of subsequent bending or stretching, so that the use stability is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for preparing a flexible screen and the flexible screen. Background technique [0002] With the continuous development of science and technology and the continuous improvement of living standards, more and more electronic devices are used in people's daily life and work. Electronic equipment has brought great convenience to people's daily life and work, and has become an indispensable and important tool for people today. [0003] The display screen is a part of an electronic device for displaying information. In order to expand the display area of ​​the display screen, the display screens in the related art mostly adopt flexible display screens that can be bent. However, when the flexible display screen is bent, the metal wire will be bent or stretched many times during use, and micro-cracks or complete breaks will appear in different degrees, causing the dis...
