Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0028] Figure 1A to Figure 1F It is a schematic flow chart of the manufacturing method of the flexible display according to the first embodiment of the present invention. First, see Figure 1A to Figure 1E , which is the manufacturing process of the substrate 100 for the flexible display. In this embodiment, a FOLED (Flexible OLED, flexible organic light-emitting diode) display is taken as an example. In this embodiment, the substrate 100 for making a flexible display is a FOLED panel, that is, the substrate 100 for making a flexible display can be Finally, an independent flexible display is formed, such as a FOLED display.

[0029] see Figure 1A , providing a hard su...

Abstract

The invention discloses a method for manufacturing a flexible display device and the flexible display device obtained through the manufacturing method. The method comprises the steps that a conductive layer is formed on the surface of a hard substrate; an inverse electrostriction thin film layer is formed on the conductive layer; a flexible base material is attached to the surface of the inverse electrostriction thin film layer; a display element layer is manufactured on the flexible base material; after the display element layer is manufactured, alternating currents are applied to the conductive layer, and the hard substrate and the flexible base material are separated through the micromechanical vibration of an inverse electrostriction thin film. The inverse electrostriction thin film layer on the hard substrate is adopted as a release layer, after the alternating currents are applied, mechanical stress between the inverse electrostriction thin film and the flexible base material is far smaller than binding force between the inverse electrostriction thin film and the lower hard substrate, the flexible base material and the hard substrate can be separated, the hard substrate can be used repeatedly, manufacturing cost is greatly saved, production efficiency is improved, and the product yield is improved.

Description

technical field [0001] The invention relates to the technical field of flexible display devices, in particular to a method for preparing a flexible display device and a display device obtained by the method. Background technique [0002] Flexible organic light-emitting displays have the advantages of self-luminous display, fast response, high brightness, wide viewing angle, and low cost. They can be rolled, folded, and even used as part of wearable computers. and other special fields have a very wide range of applications. [0003] At present, the preparation methods of flexible display products are mainly divided into two categories. The first type is to use the roll to roll method (roll to roll), but due to the limitation of printing technology, only some products with low precision requirements can be prepared, and the yield and reliability are poor; The method of removal: Paste the flexible substrate on the hard backplane to prepare display products, and remove the har...
