[0044] 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.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0046] Currently, display panels are attached to the LCD screen using transparent optical adhesive, either frame-mounted or fully-mounted. However, the adhesive strength of transparent optical adhesive is relatively strong. When it is necessary to separate the bonded glass cover from the LCD screen, it is easy to damage the LCD panel or the glass cover, making rework impossible.

[0047] For example, Figure 1 A schematic diagram of a display panel using a frame-mount method is provided for the prior art, such as... Figure 1 As shown, the display panel includes a glass cover plate 210, a transparent optical adhesive 220, and a first liquid crystal display layer 130. The first liquid crystal display layer 130 is bonded to the glass cover plate 210 by the transparent optical adhesive 220 disposed in its bezel area. Figure 2 A schematic diagram of a display panel using a full-lamination method is provided for the present technology, such as... Figure 2 As shown, the display panel includes a glass cover plate 210, a transparent optical adhesive 220, and a first liquid crystal display layer 130. The first liquid crystal display layer 130 is bonded to the glass cover plate 210 by the transparent optical adhesive 220 covering the entire surface. Both of these display panels have the problems of being difficult to disassemble and being prone to damage to the first liquid crystal display layer or the cover plate during disassembly, resulting in poor repairability and reworkability of the display panel.

[0048] This application addresses the problem of difficulty in disassembling the glass cover and the first liquid crystal display layer when using frame-mounting and full-mounting methods in the prior art, and proposes a display panel provided in the embodiments of this application.

[0049] Figure 3 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present utility model, as shown below. Figure 3 As shown, the display panel includes a removable layer 110, a magnetic layer 120, and a first liquid crystal display layer 130; the removable layer 110 includes a cover plate or a second liquid crystal display layer.

[0050] The magnetic layer 120 is disposed between the removable layer 110 and the first liquid crystal display layer 130; or, the magnetic layer 120 is disposed on at least one co-directional edge side of the removable layer 110 and the first liquid crystal display layer 130; the magnetic layer 120 is used to attach the removable layer 110 and the first liquid crystal display layer 130.

[0051] The magnetic layer 120 is made of a transparent magnetic material synthesized from silica aerogel and ultrafine neodymium iron boron magnetic powder. During the synthesis process, the transparent magnetic material is oriented by a magnetic field, thus giving it the light transmittance of aerogel and the unique magnetic properties of neodymium iron boron, enabling it to maintain magnetic field orientation like a traditional permanent magnet.

[0052] Specifically, the magnetic layer 120 has two mutually attractive poles, allowing the detachable layer 110 and the first liquid crystal display layer 130, which are fixedly connected by different poles of the magnetic layer 120, to adhere tightly together under the mutual attraction of the two poles of the magnetic layer 120. Therefore, during the peeling process of the detachable layer 110, the detachable layer 110 and the first liquid crystal display layer 130 can be completely separated simply by overcoming the magnetic attraction of the two poles of the magnetic layer 120.

[0053] This embodiment of the invention provides a magnetic layer 120 between the removable layer 110 and the first liquid crystal display layer 130, or provides a magnetic layer 120 on at least one co-directional edge side of the removable layer 110 and the first liquid crystal display layer 130. This allows the removable layer 110 and the first liquid crystal display layer 130, which are fixedly connected by different poles of the magnetic layer 120, to be tightly adhered and fixed together under the mutual attraction of the two poles of the magnetic layer 120. Therefore, during the peeling process of the removable layer 110, only the magnetic attraction of the two poles of the magnetic layer 120 needs to be overcome to completely separate the removable layer 110 and the first liquid crystal display layer 130. This reduces the difficulty of separating the removable layer 110 from the liquid crystal display layer, improves the integrity of the separation process, and thus improves the repairability and reworkability of the display panel.

[0054] Based on the above embodiments, optionally, Figure 4 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 4 As shown, the magnetic layer 120 includes a first magnetic layer 121 and a second magnetic layer 122; the first magnetic layer 121 is disposed on the side of the removable layer 110 facing the first liquid crystal display layer 130, and the second magnetic layer 122 is disposed on the side of the first liquid crystal display layer 130 facing the removable layer 110.

[0055] The first magnetic layer 121 is fixedly connected to the side of the removable layer 110 facing the first liquid crystal display layer 130, and the second magnetic layer 122 is fixedly connected to the side of the first liquid crystal display layer 130 facing the removable layer 110. Thus, the removable layer 110 and the first liquid crystal display layer 130 can be tightly adhered and fixed together by the mutual attraction between the first magnetic layer 121 and the second magnetic layer 122. Therefore, during the process of peeling off the removable layer 110, the removable layer 110 and the first liquid crystal display layer 130 can be completely separated simply by overcoming the magnetic attraction of the first magnetic layer 121 and the second magnetic layer 122.

[0056] Furthermore, current display panels, which use a frame-mount method to attach and fix the glass cover to the LCD screen with transparent optical adhesive, suffer from problems such as low transmittance, susceptibility to bulging, and the creation of depth issues. For example... Figure 1 As shown, the refractive index difference between the first liquid crystal display layer 130, the air gap, and the removable layer 110 through which light passes is relatively large, resulting in the current display panel still having problems with low transmittance and depth of field.

[0057] This application addresses the problems of low transmittance, easy bulging, depth of field issues, and difficulty in disassembly in existing technologies by proposing an alternative display panel.

[0058] Figure 5This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 5 As shown, the refractive index of the first magnetic layer 121 is greater than that of the second magnetic layer 122; the side of the first magnetic layer 121 facing the first liquid crystal display layer 130 is a matrix of multiple concave arc-shaped surfaces, and the side of the second magnetic layer 122 facing the removable layer 110 is a matrix of multiple convex arc-shaped surfaces, with each concave arc-shaped surface matching the convex arc-shaped surface at a relative position.

[0059] The display panel also includes a first upper polarizing layer 141 and a lower polarizing layer (not shown in the figure); the light transmission axes of the first upper polarizing layer 141 and the lower polarizing layer are perpendicular to each other. The first upper polarizing layer 141 is disposed between the second magnetic layer 122 and the first liquid crystal display layer 130; the lower polarizing layer is disposed on the side of the first liquid crystal display layer 130 away from the removable layer 110.

[0060] Specifically, on the side of the removable layer 110 facing the first liquid crystal display layer 130, a high-refractive-index transparent magnetic material (e.g., refractive index 1.8, coating thickness approximately 7 μm, etched to form a matrix of recessed arc-shaped surfaces, with the magnetic direction N-pole downwards) can be coated using methods such as chemical vapor deposition to form the first magnetic layer 121. On the side of the first liquid crystal display layer 130 facing the removable layer 110, a low-refractive-index transparent magnetic material (e.g., refractive index 1.5, coating thickness approximately 3 μm, etched to form a matrix of convex arc-shaped surfaces, with the magnetic direction S-pole downwards) can be coated using methods such as chemical vapor deposition to form the second magnetic layer 122.

[0061] Specifically, after light passes through the low-refractive-index second magnetic layer 122 and then through the high-refractive-index first magnetic layer 121, the light converges, increasing light transmittance and enhancing the center brightness of the display panel, thus achieving a brightening effect. The first magnetic layer 121 and the second magnetic layer 122 attract each other, which can buffer the increased glass warping caused by vacuuming and reduce the depth-of-field phenomenon.

[0062] Based on the above embodiments, alternatively, refer to the following: Figure 5 The display panel also includes an explosion-proof layer 150 and a backlight 160. The explosion-proof layer 150 is disposed on the side of the removable layer 110 away from the first liquid crystal display layer 130, and the backlight 160 is disposed on the side of the first liquid crystal display layer 130 away from the removable layer 110.

[0063] Specifically, the explosion-proof layer 150 provides splash protection (when the panel is impacted and broken, the explosion-proof layer 150 will adhere to the broken glass fragments, preventing them from flying and injuring people or damaging surrounding equipment), impact cushioning (it has a certain degree of toughness and can absorb some external impact force, reducing the probability of direct panel breakage and extending the panel's lifespan), and auxiliary protection (it can block dust and minor liquid penetration, protecting the internal circuitry of the panel from minor corrosion from the external environment without affecting the display effect). The backlight 160 provides uniform and stable light to the display panel, ensuring that the displayed image is clearly visible.

[0064] Based on the above embodiments, optionally, Figure 6 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 7 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 6 and Figure 7 As shown, the refractive index of the first magnetic layer 121 is equal to the refractive index of the second magnetic layer 122;

[0065] The display panel also includes a second upper polarizing layer 142 and a lower polarizing layer (not shown in the figure); the light transmission axes of the second upper polarizing layer 142 and the lower polarizing layer are perpendicular to each other. The second upper polarizing layer 142 is disposed between the first magnetic layer 121 and the second magnetic layer 122; or, the second upper polarizing layer 142 is disposed between the second magnetic layer 122 and the first liquid crystal display layer 130; the lower polarizing layer is disposed on the side of the first liquid crystal display layer 130 away from the removable layer 110.

[0066] Specifically, the magnetic direction of the first magnetic layer 121 on the side of the removable layer 110 facing the first liquid crystal display layer 130 is downward (N pole), and the magnetic direction of the second magnetic layer 122 on the side of the first liquid crystal display layer 130 facing the removable layer 110 is upward (S pole). The overall coating thickness of the first magnetic layer 121 and the second magnetic layer 122 is 3~7µm. The first magnetic layer 121 and the second magnetic layer 122 attract each other, which can buffer the glass warping caused by vacuuming and reduce the depth of field phenomenon. The refractive index of the first magnetic layer 121 and the refractive index of the second magnetic layer 122 are equal, thereby eliminating the refraction of light from the second magnetic layer 122 through the first magnetic layer 121, increasing the amount of light passing through the second magnetic layer 122 through the first magnetic layer 121, and thus improving the transmittance of the display panel.

[0067] Based on the above embodiments, optionally, Figure 8 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 9 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 8 and Figure 9As shown, the magnetic layer 120 includes at least one first magnetic strip 123 and at least one second magnetic strip 124;

[0068] At least one first magnetic strip 123 is disposed along a first direction in the border area of ​​the removable layer 110 toward the first liquid crystal display layer 130; and / or, at least one first magnetic strip 123 is disposed along a second direction in the border area of ​​the removable layer 110 toward the first liquid crystal display layer 130; at least one second magnetic strip 124 is disposed along a first direction in the border area of ​​the first liquid crystal display layer 130 toward the removable layer 110; and / or, at least one second magnetic strip 124 is disposed along a second direction in the border area of ​​the first liquid crystal display layer 130 toward the removable layer 110; each first magnetic strip 123 and a second magnetic strip 124 are disposed opposite to each other; the first direction and the second direction are perpendicular.

[0069] Wherein, the first direction is the longitudinal direction of the display panel, and the second direction is the transverse direction of the display panel. For example, the thickness of the first magnetic strip 123 and the second magnetic strip 124 can be approximately 100 μm. The magnetic direction of the first magnetic strip 123 is N-pole downwards, and the magnetic direction of the second magnetic strip 124 is S-pole upwards. The opposing first magnetic strip 123 and the second magnetic strip 124 attract each other and adhere tightly together. Therefore, during the peeling of the removable layer 110, the removable layer 110 and the first liquid crystal display layer 130 can be completely separated simply by overcoming the magnetic attraction of the first magnetic strip 123 and the second magnetic strip 124.

[0070] In another embodiment, the removable layer 110 includes only the second liquid crystal display layer. Figure 10 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figure 11 This is a schematic diagram of another display panel provided in an embodiment of the present utility model. Figures 10-11 As shown, the magnetic layer 120 includes at least one third magnetic strip 125 and at least one fourth magnetic strip 126;

[0071] At least one third magnetic strip 125 is disposed along the edge side of the removable layer 110 in a first direction, and / or at least one third magnetic strip 125 is disposed along the edge side of the removable layer 110 in a second direction; at least one fourth magnetic strip 126 is disposed along the edge side of the first liquid crystal display layer 130 in a first direction, and / or at least one fourth magnetic strip 126 is disposed along the edge side of the first liquid crystal display layer 130 in a second direction; each third magnetic strip 125 is disposed opposite to a fourth magnetic strip 126; the first direction and the second direction are perpendicular.

[0072] Wherein, the first direction is the longitudinal direction of the display panel, and the second direction is the transverse direction of the display panel. For example, the thickness of the third magnetic strip 125 and the fourth magnetic strip 126 can be approximately 100 μm. The magnetic direction of the third magnetic strip 125 is N-pole downward, and the magnetic direction of the fourth magnetic strip 126 is S-pole upward. The opposing third magnetic strip 125 and fourth magnetic strip 126 attract each other and adhere tightly together. Therefore, during the peeling of the removable layer 110, the removable layer 110 and the first liquid crystal display layer 130 can be completely separated simply by overcoming the magnetic attraction of the third magnetic strip 125 and the fourth magnetic strip 126.

[0073] In addition, based on the above embodiments, alternatively, reference can be continued. Figures 8-11 The display panel also includes a third upper polarizing layer 143 and a lower polarizing layer (not shown in the figure); the light transmission axes of the second upper polarizing layer 142 and the lower polarizing layer are perpendicular to each other. The third upper polarizing layer 143 is disposed between the removable layer 110 and the first liquid crystal display layer 130, and its projection onto the first liquid crystal display layer 130 covers the display area of ​​the first liquid crystal display layer 130; the lower polarizing layer is disposed on the side of the first liquid crystal display layer 130 away from the removable layer 110.

[0074] Additionally, it should be noted that the first magnetic layer, second magnetic layer, first magnetic strip, second magnetic strip, third magnetic strip, and fourth magnetic strip proposed in this embodiment are all made of transparent magnetic materials synthesized from silica aerogel and ultrafine neodymium iron boron magnetic powder. The materials used to make the first magnetic layer, second magnetic layer, first magnetic strip, second magnetic strip, third magnetic strip, and fourth magnetic strip have been disclosed in the prior art, and this application will not elaborate on them in detail.
