Embodiment Construction

[0067] In order for those skilled in the art to better understand the technical solution of the present invention, the method for attaching the film layer, the method for manufacturing the display panel and the display device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0068] figure 1 For the process flow chart of the existing flexible display panel, please refer to figure 1 , the process includes:

[0069] S1, OLED organic film evaporation;

[0070] S2, film encapsulation;

[0071] S3, the whole surface protective film is attached;

[0072] S4, laser lift off transparent substrate and flexible substrate;

[0073] S5, attaching a base film on the back of the flexible substrate;

[0074] S6, cutting the flexible substrate using a laser to form a plurality of display panels; and half-cutting the protective film in the bonding area using laser cutting;

[0075] S7, peeling off the protective film in the ...

Abstract

The invention provides a coating attaching method, a display panel and a manufacturing method of a display device. The coating attaching method includes: a step of pre-cutting: cutting a coating alongthe thickness direction to remove a part corresponding to a first zone in a binding area of the display panel; a step of attaching: aligning the coating after being cut and the display panel, and attaching the film onto a to-be-attached surface of the display panel to enable an area where the removed part of the coating is located to correspond to the first zone of the display panel. By the technical scheme, the problem that a lead in the binding area is cut off or the coating cannot be cut off can be avoided, so that cutting yield and automated operation are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for attaching a film layer, a method for manufacturing a display panel and a display device. Background technique [0002] Compared with traditional displays, flexible OLED (Organic Light-Emitting Diode) displays are not only thinner and lighter in size, but also lower in power consumption, which helps to improve the battery life of the device. With good flexibility, its durability is also much higher than that of traditional display screens, thereby reducing the probability of accidental damage to equipment. [0003] In the existing flexible display panel process flow, in order to improve production efficiency, it is necessary to attach the top protective film (TPF) to the substrate in the flexible process flow, and use laser cutting to bond the bonding area during the subsequent process. The protective film is cut in half and removed. However, this will have...
