Description

TECHNICAL FIELD

[0001] The utility model relates to display screen technical field especially application in display module's laminated structure. BACKGROUND

[0002] At present, dyne value is a numerical unit representing surface tension, which is the result obtained when dyne pen is used to test material surface, also called surface tension coefficient. Among them, the higher the dyne value, the higher the material surface energy, so the surface tension is larger, and the liquid is more easily spread on its surface.

[0003] In the related art, the AMOLED screen and the glass cover plate are laminated by solid-state optical adhesive and glass cover plate ink surface. The glass cover plate non-ink surface is laminated by double-sided adhesive and front cover ink surface. However, the dyne value of the glass cover plate non-ink surface will be smaller, so the adhesion of the double-sided adhesive during the lamination process will decrease, resulting in separation of the front cover and the glass cover plate. UTILITY MODEL CONTENT

[0004] The utility model discloses a laminated structure applied to display module, which can improve the adhesion of the front cover and the glass cover plate and prevent the separation of the front cover and the glass cover plate.

[0005] The utility model discloses a laminated structure applied to display module, which can improve the adhesion of the front cover and the glass cover plate and prevent the separation of the front cover and the glass cover plate.

[0006] The utility model discloses a laminated structure applied to display module, which can improve the adhesion of the front cover and the glass cover plate and prevent the separation of the front cover and the glass cover plate.

[0007] The display assembly further comprises an optical adhesive layer, which is arranged on the glass cover plate away from the ink layer.

[0008] The display assembly further comprises a screen body, which is arranged on the optical adhesive layer.

[0009] The thickness of the adhesive layer is 0.3mm.

[0010] The thickness of the ink layer ranges from 20μm to 30μm.

[0011] The front cover is made of acrylic material.

[0012] The display assembly further comprises a binding position, which is arranged on the screen body.

[0013] The display assembly further comprises an FPC board, which is arranged on the binding position.

[0014] The protective film is arranged on the front cover.

[0015] The tear handle is arranged on the protective film.

[0016] Compared with the prior art, the utility model has at least the following advantages:

[0017] Since the glass cover plate silk screen ink layer is mainly used for alignment when adhering AMOLED, the non-ink surface of the adhered glass cover plate does not affect the alignment. The conventional dauric value of the glass cover plate ink surface can reach more than 32, so it is used for pasting the adhesive layer, and the adhesion of the adhesive layer will be much higher, which can improve the rebound between the glass cover plate and the front cover and prevent the separation of the two.

[0021] The embodiments of the present application will be described in more detail below with reference to the drawings. Although the embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0022] It should be understood that although the terms "first", "second", "third" and the like can be used to describe various information in the present application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the present application. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0023] Unless otherwise defined, the terms "mounting", "connected", "connecting", "fixed", and "fixedly" are to be construed as broad terms, for example, can be fixed connection, can also be detachable connection or integral; can be mechanical connection, can also be electrical connection; can be direct connection, can also be indirect connection through an intermediate medium, can be internal connection of two elements or interaction relationship of two elements. The specific meaning of the above terms in the present application can be understood according to the specific circumstances by those skilled in the art.

[0024] At present, the AMOLED screen and the glass cover plate are attached by solid optical adhesive and glass cover plate ink surface. The non-ink surface of the glass cover plate is attached to the front cover ink surface by double-sided adhesive. However, the daoyin value of the non-ink surface of the glass cover plate is small, and the surface daoyin value is difficult to control, so the adhesion of the double-sided adhesive in the front cover attachment process decreases, resulting in separation of the front cover and the glass cover plate.

[0025] In view of the above problems, the embodiment of the present application provides a kind of application in display module's attachment structure, can improve the adhesion of front cover and glass cover plate, prevent front cover and glass cover plate from separating.

[0026] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0027] Please refer to Figure 1 A kind of application in display module's attachment structure, including: front cover 100 and display component 200, display component 200 includes glass cover plate 210, ink layer 220 and adhesive layer 230, glass cover plate 210 is set on front cover 100, ink layer 220 is set on glass cover plate 210, adhesive layer 230 one side is set on ink layer 220, adhesive layer 230 other side is adhered to front cover 100.

[0028] It should be noted that the adhesive layer 230 is double-sided adhesive, which realizes adhesion by the interaction between the adhesive substance of the double-sided adhesive and the surface of the adherend. The daoyin value reflects the surface energy of the object. When the daoyin value of the surface of the adherend is high, it means that the surface energy is high, and the adhesive substance of the double-sided adhesive is more likely to form a strong interaction force, so that when the front cover 100 contacts the double-sided adhesive, the intermolecular attraction is enhanced, the double-sided adhesive can be better attached, and the adhesion is significantly improved, thereby preventing the front cover 100 and the glass cover plate 210 from separating.

[0029] It should be further noted that the ink layer 220 is screen printed on the glass cover plate 210.
