Description

Technical Field

[0001] This utility model relates to the field of AMOLED module technology, and in particular to an antistatic PET adhesive structure for wearable AMOLED modules. Background Technology

[0002] AMOLED is a display technology. OLED (Organic Light Emitting Diode) describes a specific type of thin-film display technology: organic electroluminescent display; AM (Active Matrix) refers to the pixel addressing technology behind it. AMOLED technology is mainly used in smartphones and continues to develop towards lower power consumption, lower cost, and larger screen sizes.

[0003] As per the instruction manual Figure 7 As shown, the back of the display glass 1-1 is protected by a full-surface PET adhesive 1-2. When the whole device is subjected to electrostatic discharge during electrostatic testing or use, the static electricity will be preferentially conducted to the display glass 1-1. The display glass 1-1 damaged by electrostatic discharge may cause display abnormalities or circuit damage, which is not conducive to the protection of the wearable AMOLED module itself. Therefore, a PET adhesive antistatic structure for wearable AMOLED modules is proposed. Utility Model Content

[0004] Therefore, it is necessary to address the aforementioned technical issues by providing a PET adhesive antistatic structure for wearable AMOLED modules. This structure involves inwardly designing the PET adhesive layer on the back of the conventional AMOLED screen glass to create an annular antistatic area. A conductive adhesive frame is then laid within this annular antistatic area. This allows static electricity to be preferentially transferred to the conductive adhesive frame and ultimately released to the outside through the conductive frame, preventing direct transfer to the AMOLED screen glass and thus avoiding display abnormalities.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An antistatic PET adhesive structure for wearable AMOLED modules includes an AMOLED screen glass, with a PET adhesive layer on the back of the AMOLED screen glass. The PET adhesive layer covers a portion of the back of the AMOLED screen glass, such that the outer dimensions of the PET adhesive layer are smaller than those of the AMOLED screen glass.

[0007] The PET adhesive layer has an annular antistatic zone around its periphery and the AMOLED screen glass. A conductive adhesive frame is laid in the annular antistatic zone and is in direct contact with the back of the AMOLED screen glass. The conductive adhesive frame allows static electricity to be preferentially conducted into the frame and then transferred and released to the outside.

[0008] Furthermore, the edge of the conductive adhesive frame extends outward to form an electrostatic discharge area, and the edge of the conductive adhesive frame is recessed inside the AMOLED screen glass.

[0009] Furthermore, the conductive frame is made of either conductive silver paste or conductive tape.

[0010] Furthermore, the thickness of the conductive adhesive frame is the same as the thickness of the PET adhesive layer.

[0011] Furthermore, the inner side of the conductive adhesive frame is tightly bonded to the outer side of the PET adhesive layer.

[0012] Furthermore, the conductive rubber frame contacts the external grounding area to release introduced static electricity.

[0013] Furthermore, the inner side of the conductive frame has an interlocking structure, and the outer side of the PET adhesive layer has an interlocking groove that matches the position of the interlocking structure. The interlocking structure can increase the contact area between the PET adhesive layer and the conductive frame.

[0014] Furthermore, the interlocking structure is an interlocking portion extending from the inside of the conductive adhesive frame toward the PET adhesive layer.

[0015] Furthermore, the shape of the occlusal portion is one of a rectangle, trapezoid, triangle, or swallowtail.

[0016] Furthermore, a glass cover plate is attached to the top surface of the AMOLED screen glass using optical adhesive.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The PET adhesive antistatic structure for wearable AMOLED modules provided by this utility model has an inward-shrinking design of the PET adhesive layer on the back of the conventional AMOLED screen glass, while leaving an annular antistatic area around the PET adhesive layer. Conductive adhesive frames can be laid in the annular antistatic area. With the above design, when the AMOLED module is subjected to static electricity, the static electricity can be preferentially transferred to the conductive adhesive frame and finally discharged to the outside through the conductive adhesive frame, avoiding the static electricity from being directly transferred to the AMOLED screen glass and causing problems such as display abnormalities.

[0019] By using the interlocking structure and interlocking groove, the contact area between the conductive frame and the PET adhesive layer can be increased after bonding. This allows for interlocking connections and effectively improves the overall interface connection stability. Attached Figure Description

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] As described in the background art, as per the appendix to the specification. Figure 7As shown, the back of the display glass 1-1 is protected by a full-surface PET adhesive 1-2. During electrostatic discharge testing or use, if the device is damaged by electrostatic discharge (the upper right corner of the image shows the electrostatic discharge indicator), the static electricity will be preferentially conducted to the display glass 1-1 (the path of static electricity transmission is...). Figure 7 (The text uses dashed lines and electrostatic indicators to connect and display the screen). Display glass 1-1 damaged by electrostatic discharge may cause display abnormalities or circuit damage, which is not conducive to the protection of the AMOLED module itself.

[0033] To address this technical problem, this invention provides a PET adhesive antistatic structure for wearable AMOLED modules, which is applied to wearable AMOLED modules.

[0034] For details, please refer to Figures 1-7 As shown, the PET adhesive antistatic structure for wearable AMOLED modules specifically includes an AMOLED screen glass 1, with a PET adhesive layer 2 on the back of the AMOLED screen glass 1. The PET adhesive layer 2 covers part of the back of the AMOLED screen glass 1, making the outer dimensions of the PET adhesive layer 2 smaller than the AMOLED screen glass 1.

[0035] An annular antistatic area 21 is provided at the periphery of the PET adhesive layer 2 and the periphery of the AMOLED screen glass 1. A conductive adhesive frame 22 is laid in the annular antistatic area 21 and is in direct contact with the back of the AMOLED screen glass 1. The conductive adhesive frame 22 allows static electricity to be preferentially introduced into it and then transferred and released to the outside.

[0036] The PET adhesive antistatic structure for wearable AMOLED modules provided by this utility model has an inwardly recessed design for the PET adhesive layer 2 on the back of the conventional AMOLED screen glass 1, while leaving an annular antistatic area 21 around the PET adhesive layer 2. Conductive adhesive frame 22 can be laid within the annular antistatic area 21. Through the above design, when the AMOLED module is subjected to static electricity, the static electricity can be preferentially transferred to the conductive adhesive frame 22, and finally discharged to the outside through the conductive adhesive frame 22, avoiding the static electricity from being directly transferred to the AMOLED screen glass 1, which could cause display abnormalities and other problems.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] Example 1

[0041] Please refer to Figures 1-6 As shown, a PET adhesive antistatic structure for wearable AMOLED modules includes an AMOLED screen glass 1, a PET adhesive layer 2 on the back of the AMOLED screen glass 1, the PET adhesive layer 2 covering part of the back of the AMOLED screen glass 1, such that the outer dimensions of the PET adhesive layer 2 are smaller than those of the AMOLED screen glass 1.

[0042] Wherein, an annular antistatic area 21 is left at the periphery of the PET adhesive layer 2 and the periphery of the AMOLED screen glass 1. In this embodiment, the annular antistatic area 21 is formed after the edge of the conventional PET adhesive layer is shrunken inward. That is to say, the overall size of the PET adhesive layer 2 in this embodiment is smaller than the PET layer attached to the back of the conventional AMOLED screen glass.

[0043] The annular antistatic zone 21 is provided with a conductive adhesive frame 22, which is in direct contact with the back of the AMOLED screen glass 1. The conductive adhesive frame 22 allows static electricity to be preferentially introduced into it and then transferred and released to the outside. In this embodiment, the overall size of the conductive adhesive frame 22 and the PET adhesive layer 2 inside it is the same as the size of the PET adhesive layer on the front and back of a conventional AMOLED screen glass.

[0044] The conductive frame 22 is made of either conductive silver paste or conductive tape. Both materials can guide static electricity after being subjected to electrostatic discharge, similar to the principle of a lightning rod in a conventional lightning protection structure. This allows static electricity to be preferentially introduced into the conductive frame 22 and then led out through the ground wire (not shown in the figure) in contact with the conductive frame 22. This avoids the static electricity being directly transferred to the surface of the AMOLED screen glass 1, which could easily cause abnormal display or even damage to the AMOLED screen glass 1.

[0045] The thickness of the conductive adhesive frame 22 is the same as the thickness of the PET adhesive layer 2. In the actual setting process of the conductive adhesive frame 22 in this embodiment, it is necessary to ensure that it is the same as the thickness of the PET adhesive layer 2. In this way, while meeting the actual conductive performance, it will not protrude from the surface of the PET adhesive layer 2, which would easily affect the subsequent alignment and assembly.

[0046] Furthermore, such as Figure 1 As shown, a glass cover plate 3 is attached to the top surface of the AMOLED screen glass 1 using optical adhesive;

[0047] In summary, this embodiment includes a pre-reserved annular antistatic area 21 on the basis of conventional AMOLED screen glass 1, allowing for the laying of conductive adhesive frame 22 within it. Figure 1 As shown, static electricity can be introduced first (the upper right corner is marked with static electricity, and the current is introduced by connecting the dotted line with the conductive frame), and then led out in the grounding wire, thereby avoiding the problem of direct damage to the AMOLED screen glass 1, and thus achieving anti-static protection for the entire AMOLED module.

[0048] Example 2

[0049] The antistatic structure of the PET adhesive for wearable AMOLED modules provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the edge of the conductive frame 22 extends outward to form an electrostatic discharge area, and the edge of the conductive frame 22 is recessed inside the AMOLED screen glass 1.

[0050] With the above structural setup, the design requirement of conductive frame 22 on the outside of PET adhesive layer 2 can be met. At the same time, after the conductive frame 22 is set, the overall size formed by it and PET adhesive layer 2 will not exceed the size of PET adhesive layer on the back and front of conventional AMOLED screen glass. This ensures that the overall module structure size will not change, thereby meeting the antistatic requirements without causing assembly difficulties.

[0051] The inner side of the conductive adhesive frame 22 is tightly bonded to the outer side of the PET adhesive layer 2. Since the PET adhesive layer 2 and the conductive adhesive frame 22 are independently bonded to the back of the AMOLED screen glass 1, their opposite sides are tightly bonded, which promotes their connection relationship and improves the overall connection stability.

[0052] The conductive adhesive frame 22 contacts the external grounding area to release introduced static electricity. For example, in practical applications, the conductive adhesive frame 22 can be in close contact with the casing or ground wire to discharge static electricity. Since the design of the casing or internal ground wire inside the conventional assembly is common knowledge known to those skilled in the art, no further elaboration is needed in this embodiment.

[0053] Example 3

[0054] The antistatic structure of the PET adhesive for wearable AMOLED modules provided in Embodiment 1 or 2 is further optimized, such as... Figure 4 , Figure 5 and Figure 6As shown, the inner side of the conductive frame 22 has an interlocking structure 23, and the outer side of the PET adhesive layer 2 has an interlocking groove 24 that matches the position of the interlocking structure 23. The contact area between the PET adhesive layer 2 and the conductive frame 22 can be increased by the action of the interlocking structure 23.

[0055] The interlocking structure 23 is an interlocking portion 25 extending from the inside of the conductive frame 22 toward the PET adhesive layer 2;

[0056] Since the PET adhesive layer 2 and the conductive frame 22 are both independently bonded to the back of the AMOLED screen glass 1, they are not a single integrated unit. Therefore, in this embodiment, the interlocking structure 23 is designed so that the outer side of the PET adhesive layer 2 and the inner side of the conductive frame 22 are in a non-planar contact state. At the same time, the interlocking part 25 and the interlocking groove 24 form an embedded state, which can increase the effective contact area of ​​the contact surface. In this way, the interface stability at the connection between the PET adhesive layer 2 and the conductive frame 22 can be improved through the physical interlocking structure.

[0057] Furthermore, such as Figure 4 As shown, the bite portion 25 is rectangular in shape;

[0058] Furthermore, such as Figure 5 As shown, the bite portion 25 is triangular in shape;

[0059] The aforementioned bite portion 25 can also be designed as a trapezoid (not shown in the figure). The specific shape of the bite portion 25 is not limited in this embodiment. By extending the bite portion 25, the effective contact area with the PET adhesive layer 2 can be increased, and the contact surface can be made non-planar, which is beneficial to the connection stability at the joint.

[0060] Furthermore, such as Figure 6 As shown, the bite portion 25 is dovetail-shaped. By designing the bite portion 25 into a dovetail shape, the contact area between the conductive adhesive frame 22 and the PET adhesive layer 2 is increased, and the inner side of the conductive adhesive frame 22 is locked with the PET adhesive layer 2. This further improves the stability of the PET adhesive layer 2 and the conductive adhesive frame 22 after they are bonded together.

[0061] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0062] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
