Furthermore, the terms "first," "second," "third," and "fourth," etc. are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
It should be noted that, in case of conflict, different features in the embodiments of the present application may be combined with each other.
The Optical Clear Adhesive (OCA) film has the characteristics of high light transmittance, good Adhesive strength and the like, and is widely used in the manufacturing process of the display screen and used for bonding different films of the display screen. For example, the optical film layer can be disposed between the display module and the cover plate for bonding the display module and the cover plate.
Referring to fig. 1, fig. 1 shows a schematic view of a partial film structure of a display screen 1 ', where the display screen 1' includes an optical film layer 10 ', a display module 20', and a cover plate 30 ', where the optical film layer 10' is located between the display module 20 'and the cover plate 30', the optical film layer 10 'is used to bond the display module 20' and the cover plate 30 ', and the cover plate 30' may be a transparent cover plate made of glass.
In the following, for example, the cover plate 30 'of the four-curved display screen is attached to the display module 20' (e.g., OLED module), wherein the four-curved display screen 1 'refers to the display screen 1' in which four sides of the display screen 1 'are all bent toward the back of the display screen 1'. The four sides of the cover plate 30 ' of the quadric display screen 1 ' have curved surfaces, when the display module 20 ' is completely attached to the cover plate 30 ', the optical adhesive film layers 10 ' positioned in four vertex angle areas of the display module 20 ' can be subjected to extrusion stress in two directions of the cover plate 30 ', and optical adhesive at a part of the optical adhesive film layers 10 ' can generate film layer redundancy relative to a plane protrusion where the optical adhesive film layers 10 ' are positioned under the action of the extrusion stress in two different directions.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a quadric display panel 1 'forming a film redundancy 101' in a corner region. The inventor finds that the film layer redundancy 101 'is approximately V-shaped, and gradually increases from the inside of the screen body of the display screen 1' to the edge of the screen body, so that cracks may be generated in the display screen 1 'after the film layer redundancy 101' is generated in the optical adhesive film layer 10 ', and finally, a cracking problem may occur, so that water vapor may penetrate into a visible Area (AA) through the cracks to cause poor light emission (such as black spots or light leakage), which may seriously affect the product performance and shorten the service life of the display screen 1'.
The inventor researches the above phenomena to find that the optical adhesive film layer is generally made of a flexible material, and the thickness of the optical adhesive film layer 10 'is generally thick (for example, greater than 100um), so that when the display module 20' is attached to the cover plate 30 ', film redundancy occurs when the optical adhesive film layer 10' is subjected to compressive stress in different directions.
In order to solve the technical problems, the inventor innovatively designs the following technical scheme that the absorption part is correspondingly arranged in the bendable region of the optical adhesive film layer to absorb film layer redundancy formed by extrusion stress of the optical adhesive film layer in the bendable region, which is acted on the optical adhesive film layer in different directions by the curved surface structure of the cover plate.
