Problems solved by technology

[0002] The production process of the flexible display panel includes a cutting process. The cutting process used in the prior art is mainly to directly adsorb the flexible display panel on the cutting machine for single-beam laser cutting. The flexible display panel after cutting is easy to cut. Warping and air bubbles occur at the edge of the cutting area, and the size of the heat-affected zone and the size of the carbonized area are large, which affects the yield of the product and is not conducive to realizing the narrow frame of the flexible display panel

Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] After repeated research by the inventors of the present invention, it was found that the flexible display panel after cutting in the prior art is prone to warping and bubbles at the edge of the cutting area, and the reason why the size of the heat-affected zone and the size of the carbonized area are relatively large in:

[0041] In the prior art, a single laser beam is directly used for cutting without any shielding of the initial flexible display panel. During the cutting process, the laser beam first hits the upper surface of the flexible display panel. At this time, due to The structure of the film layers in the structure of the flexible display pane...

Abstract

The present invention provides a mask assembly. The mask assembly is used for the process of cutting an initial flexible display panel. The mask assembly comprises at least one mask; each mask comprises a limiting frame and a limiting plate; the limiting frames are arranged around the limiting plates; one side face of each limiting plate is fixedly connected with the corresponding limiting frame,and gaps are formed between the other sides of each limiting plate and the inner side faces, opposite to the other sides of each limiting plate, of the corresponding limiting frame; surfaces of the limiting frames and the surfaces of the limiting plates which are in the same direction are jointly formed limiting surfaces; and the limiting surfaces are used for being attached to the initial flexible display panel. The invention further provides a cutting device and method for cutting the initial flexible display panel. Through the mask assembly, the edges of a cut area of the initial flexible display panel can be prevented from warping.

Description

technical field [0001] The present invention relates to the technical field of cutting flexible display panels, in particular to a mask assembly, a cutting device for cutting an initial flexible display panel, and a method for cutting an initial flexible display panel. Background technique [0002] The production process of the flexible display panel includes a cutting process. The cutting process used in the prior art is mainly to directly adsorb the flexible display panel on the cutting machine for single-beam laser cutting. The flexible display panel after cutting is easy to cut. Warping and air bubbles occur at the edge of the cutting area, and the size of the heat-affected zone and the size of the carbonized area are large, which affects the yield of the product and is not conducive to realizing the narrow frame of the flexible display panel. [0003] Therefore, how to design a method for cutting the initial flexible display panel, so that the flexible display panel obt...
