Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone screen technology, specifically to a transparent border layer structure for a touch screen. Background Technology
[0002] A mobile phone touchscreen typically consists of three main layers. The bottom layer is an OLED display, which provides image display and is self-illuminating through organic light-emitting diodes, featuring high contrast and vibrant colors. The middle layer is a transparent projected capacitive touchscreen, used to detect finger touch operations and achieve precise touch functionality through changes in capacitance. The top layer is transparent tempered glass, which provides protection against scratches and impacts, while also providing a smooth touch surface. These three layers work together to enable the display and touch functions of a mobile phone screen.
[0003] In practical use, it is quite common for mobile phone touchscreens to shatter due to drops, especially tempered glass. This not only affects the appearance of the phone but may also interfere with the normal use of the touch function. Normally, when a phone is dropped face down, the impact force can be effectively dispersed due to the large contact area, so a face-down drop generally does not cause the screen to shatter. However, when a phone is dropped at an angle, especially when the screen's edge or corner hits the ground first, the impact force will be highly concentrated in a local area. In this case, the risk of screen shattering will increase significantly. This is because the structural strength of the edge and corner is relatively low and cannot effectively disperse the impact force like the face-down drop. Therefore, to address the above issues, a transparent edge layer structure for touchscreens is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a transparent bezel layer structure for touch screens to solve the problem that existing mobile phone touch screens are prone to breakage when tilted and dropped.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A transparent bezel layer structure for a touchscreen includes a display layer, a projected capacitive touch layer on the upper side of the display layer, a tempered glass substrate on the upper side of the projected capacitive touch layer, an annular groove at the upper edge of the tempered glass substrate, a protective bezel portion installed at the annular groove, the protective bezel portion including a glass bezel inside the annular groove, a buffer ring pad fixedly connected to the lower end face of the glass bezel, an adhesive ring band fixedly connected to the inner curved surface of the glass bezel, an adhesive layer fixedly connected to the lower side of the buffer ring pad and the adhesive ring band, the lower end face of the adhesive layer being bonded to the inner wall of the annular groove, and a buffer ring band sleeved on the outer side of the glass bezel.
[0007] Preferably, the buffer ring has an adhesive channel on the side away from the glass frame, and a filler ring is installed inside the adhesive channel. The inner diameter of the adhesive channel is the same as the diameter of the filler ring.
[0008] Preferably, the buffer ring pad, adhesive ring band, and adhesive layer are all transparent, and the optical transmittance of the buffer ring pad, adhesive ring band, adhesive layer, glass frame, and tempered glass substrate are all set to be the same.
[0009] Preferably, the tempered glass substrate consists of a central main substrate and an edge ring substrate, the thickness of the ring substrate of the tempered glass substrate is 0.5 times the thickness of the main substrate, and the buffer ring pad is disposed on the upper side of the ring substrate of the tempered glass substrate.
[0010] Preferably, the upper surface of the glass frame and the upper surface of the tempered glass substrate are on the same plane, and a protective flat film is attached to the upper side of the glass frame and the tempered glass substrate.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, the protective frame, tempered glass base, and protective flat film are designed to provide edge protection for the tempered glass base. The replaceable design of the protective frame allows for continuous edge protection of the screen, while the protective flat film makes the seam between the protective frame and the tempered glass base imperceptible to the user when touching the screen. This transparent frame structure effectively protects the outermost tempered glass of the touchscreen, significantly reducing the likelihood of the screen breaking at the corners of the frame during tilted drops. The replaceable design allows users to continuously protect the screen's edges by changing the protective structure, thus solving the problem of existing mobile phone touchscreens easily breaking during tilted drops.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0022] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0025] Please see Figure 1-5 This utility model provides a technical solution:
[0026] A transparent bezel layer structure for a touch screen includes a display layer 1, a projected capacitive touch layer 2 disposed on the upper side of the display layer 1, a tempered glass substrate 3 disposed on the upper side of the projected capacitive touch layer 2, an annular groove 4 formed at the upper edge of the tempered glass substrate 3, a protective bezel portion 5 installed at the annular groove 4, the protective bezel portion 5 including a glass bezel 51 located inside the annular groove 4, a buffer ring pad 52 fixedly connected to the lower end face of the glass bezel 51, an adhesive ring band 53 fixedly connected to the inner curved surface of the glass bezel 51, an adhesive layer 54 fixedly connected to the lower side of the buffer ring pad 52 and the adhesive ring band 53, the lower end face of the adhesive layer 54 being bonded to the inner wall of the annular groove 4, and a buffer ring band 55 sleeved on the outer side of the glass bezel 51.
[0027] A groove 56 is provided on the side of the buffer ring 55 away from the glass frame 51, which facilitates the application of adhesive. A filler ring 57 is installed inside the groove 56. The inner diameter of the groove 56 is the same as the diameter of the filler ring 57. This design ensures that the filler ring 57 prevents the groove 56 from becoming blocked before the protective frame part 5 is installed. The buffer ring 52, adhesive ring 53, and adhesive layer 54 are all transparent. The optical transmittance of the buffer ring 52, adhesive ring 53, adhesive layer 54, glass frame 51, and tempered glass substrate 3 are all set to be the same. This design makes it almost impossible for the user to perceive the differences between these components, thus achieving a visual effect similar to a complete screen. The tempered glass base 3 consists of a central main base and an edge ring base. The thickness of the ring base of the tempered glass base 3 is 0.5 times the thickness of the main base. A buffer ring pad 52 is set on the upper side of the ring base of the tempered glass base 3. The buffer ring pad 52 can buffer and protect the ring base of the tempered glass base 3. The upper surface of the glass frame 51 is set on the same plane as the upper surface of the tempered glass base 3. A protective flat film 6 is attached to the upper side of the glass frame 51 and the tempered glass base 3. This setting makes it impossible for the user to perceive the seam between the protective frame 5 and the tempered glass base 3 when touching the screen, thereby ensuring that the user gets a continuous and consistent tactile experience during use.
[0028] Workflow: The protective operation of the transparent bezel layer structure of the mobile phone touchscreen is as follows: Note that because the optical transmittance of the buffer ring 52, adhesive ring 53, adhesive layer 54, glass bezel 51, and tempered glass substrate 3 is consistent, users can hardly perceive the differences between these components, thus achieving a visual effect similar to a complete screen. Furthermore, due to the setting of the top layer of protective flat film 6, users cannot perceive the seam between the protective bezel 5 and the tempered glass substrate 3 when touching the screen, thus ensuring a continuous and consistent tactile experience during use. When the phone is dropped at a certain angle, the impact force will first be transmitted to the buffer ring 5 of the protective bezel 5. 5. The buffer ring 55 effectively absorbs and attenuates the impact force, significantly reducing it. The impact force is then transmitted to the glass frame 51. If the impact force is small, it will usually not damage the glass frame 51 after being attenuated by the buffer ring 55. However, if the impact force is large, even after attenuation by the buffer ring 55, it may still damage the glass frame 51, potentially causing it to shatter. Even so, the shattering of the glass frame 51 further buffers and attenuates the impact force, making it difficult for the impact force, after multiple attenuations, to damage the tempered glass substrate 3. Furthermore, due to the presence of the adhesive ring 53, the shattered glass frame 51 will not scatter, thus facilitating user recovery. The replacement operation continues. On the other hand, the impact force is also transmitted through the glass frame 51 to the buffer ring pad 52. After multiple buffering and significant attenuation by the buffer ring 55, the glass frame 51, and the buffer ring pad 52, the impact force is prevented from damaging the thinner ring base in the tempered glass base 3. Through the above multiple buffering mechanisms, the tempered glass base 3 can be effectively protected from the risk of breakage. When the user needs to replace the damaged protective frame part 5, he / she only needs to remove the protective flat film 6 first, then peel the damaged protective frame part 5 from the ring groove 4 of the tempered glass base 3, then take out the new protective frame part 5, remove the filler ring 57 on it, and apply adhesive to the glue channel 56. Next, the new protective frame 5 is inserted into the annular groove 4 of the tempered glass base 3, ensuring that the adhesive can bond the inner wall of the phone frame to the filling ring 57, and that the adhesive layer 54 is tightly bonded to the inner wall of the annular groove 4. After these steps are completed, the protective flat film 6 is reapplied, and the entire replacement operation is completed. Through this design, the transparent frame layer structure of the touch screen can effectively protect the outermost tempered glass of the touch screen, greatly reducing the probability of the screen breaking at the corner of the frame when it is tilted and dropped. The self-replaceable design allows users to continuously protect the edge of the screen by replacing the protective structure, thereby solving the problem that existing mobile phone touch screens are prone to breakage when tilted and dropped.
