Embodiment 1

[0043] This embodiment provides a cutting method for flexible media, see image 3 as well as Figure 4a-4e , the cutting method comprises the steps of:

[0044] S11, such as Figure 4a As shown, a flexible medium 10 to be cut is provided, the flexible medium comprising opposing first and second surfaces 10a, 10b. Wherein, the flexible medium 10 is, for example, a flexible OLED display panel, especially a fully flexible OLED display panel peeled off from a glass substrate.

[0045] S12, such as Figure 4bAs shown, a protective film 20 is pasted on the first surface 10 a of the flexible medium 10 . Wherein, the protective film 20 is selected as a protective film that has good adhesion to the flexible medium 10 and can be peeled off by mechanical force, preferably manually.

[0046] Wherein, the thickness of the protective film is selected to be greater than 100 μm. In a preferred technical solution, the thickness of the protective film is selected within the range of 100 μ...

Embodiment 2

[0054] This embodiment provides a method for cutting flexible media. The difference from Embodiment 1 is that it corresponds to step S13 in Embodiment 1. In this embodiment, the protective film 20 is not directly connected to the vacuum adsorption platform. 30, but on the vacuum adsorption platform 30 first connect a carrier component, and then connect the protective film 20 to the carrier component.

[0055] Such as Image 6 As shown, the vacuum adsorption platform 30 is provided with a carrier assembly 50, the flexible medium 10 attached with the protective film 20 is placed on the carrier assembly 50, the protective film 20 and the carrier assembly 50 connections. Wherein, the carrying assembly 50 is provided with a through hole 51 in fluid communication with the adsorption hole 31 of the vacuum adsorption platform 30, and the through hole 51 transmits the vacuum adsorption force generated by the vacuum adsorption platform 30 to the protection device. film 20 to absorb an...

Abstract

The invention discloses a flexible medium cutting method. The flexible medium cutting method comprises the following steps: providing a to-be-cut flexible medium comprising a first surface and a second surface which are opposite to each other; adhering a protective film to the first surface of the flexible medium; placing the flexible medium which is coated with the protective film on a vacuum adsorbing platform, wherein the protective film is connected with the vacuum adsorbing platform; controlling adsorbing holes of the vacuum adsorbing platform to generate a vacuum adsorption force, and adsorbing and fixing the protective film and the flexible medium; cutting the flexible medium from the second surface by adopting a laser cutting technique; and stripping and removing the protective film. The cutting method provided by the invention can prevent the problem about warping of the edge of the flexible medium and can also prevent the surface of the vacuum adsorbing platform from being damaged by cutting.

Description

technical field [0001] The invention relates to a production process of a flexible display panel, in particular to a cutting method of a flexible medium. Background technique [0002] Organic light-emitting diodes (Organic light-emitting diodes, OLED) display panel has the advantages of self-illumination, high contrast, thin thickness, wide viewing angle and fast response speed. Admired. Flexible OLED display panels are one of the important development trends. Flexible OLED display panels can not only be thinner and thinner in volume, but also reduce power consumption, thereby helping to improve the battery life of corresponding products. At the same time, due to the bendability and flexibility of the flexible OLED display panel, its durability is also higher than that of ordinary hard display panels. Flexible OLED display panels can be widely used in various products with display functions, such as tablet computers, TVs, mobile terminals and various wearable devices. [...
