[0036] Figure 1 This is a schematic diagram of the structure of a smartwatch provided in an embodiment of this application, such as... Figure 1 As shown, the smartwatch includes a mid-frame 10 and a display panel 20 located within the mid-frame 10.

[0037] Figure 2 This is a schematic diagram of the display panel structure of a smartwatch provided in an embodiment of this application, as shown below. Figure 2 As shown, the display panel 20 includes a first substrate 21, a display structure 22, a second substrate 23, and a near-field communication antenna 24. The first substrate 21 and the second substrate 23 are arranged opposite to each other, and the display structure 22 is located between the first substrate 21 and the second substrate 23.

[0038] As an example, the near-field communication antenna 24 is located on the surface of the second substrate 23 near the display structure 22.

[0039] In other possible implementations, the near-field communication antenna 24 may be located at at least one of the following locations:

[0040] The surface of the first substrate 21 is away from the display structure 22;

[0041] The first substrate 21 is close to the surface of the display structure 22;

[0042] Display structure 22;

[0043] The second substrate 23 is close to the surface of the display structure 22;

[0044] The second substrate 23 is located away from the surface of the display structure 22.

[0045] A display panel 20 is provided in the mid-frame 10 for display purposes. In addition to a first substrate 21, a display structure 22, and a second substrate 23, the display panel 20 also includes a near-field communication antenna 24. The near-field communication antenna 24 is located at at least one of the following locations: the surface of the first substrate 21 away from the display structure 22, the surface of the first substrate 21 close to the display structure 22, within the display structure 22, the surface of the second substrate 23 close to the display structure 22, and the surface of the second substrate 23 away from the display structure 22. Compared to providing a separate near-field communication antenna 24 in the mid-frame 10, integrating the near-field communication antenna 24 into the display panel 20 significantly reduces the space occupied by the near-field communication antenna 24 in the smartwatch, which is beneficial for the miniaturization of the smartwatch.

[0046] Taking the near-field communication antenna 24 located on the surface of the second substrate 23 near the display structure 22 as an example, the near-field communication antenna 24 can be fabricated on the surface of the second substrate 23 using semiconductor processes. For example, the near-field communication antenna 24 can be formed on the surface of the second substrate 23 using a patterning process.

[0047] In some examples, the near-field communication antenna 24 can be a transparent structure.

[0048] By making the near-field communication antenna 24 transparent, the obstruction of the near-field communication antenna 24 to the light emitted by the display structure 22 can be reduced, thereby reducing the impact of the near-field communication antenna 24 on the display effect.

[0049] For example, the near-field communication antenna 24 may be formed using a transparent conductive film, such as an indium tin oxide (ITO) film.

[0050] The display panel 20 typically has a front and a back. During the display process of the display structure 22, the image displayed on the display panel 20 can be observed from the front of the display panel 20. The display panel 20 is mounted in the middle frame 10, with the front of the display panel 20 facing the outside of the middle frame 10. In this embodiment, the second substrate 23 of the display panel 20 is located near the outside of the middle frame 10, and the side of the second substrate 23 away from the display structure 22 is the front of the display panel 20, while the side of the first substrate 21 away from the display structure 22 is the back of the display panel 20.

[0051] In the example where the near-field communication antenna 24 is arranged on the first substrate 21, the near-field communication antenna 24 will not block the light emitted by the display structure 22, and the near-field communication antenna 24 can also be an opaque structure. For example, the near-field communication antenna 24 arranged on the first substrate 21 can be formed using an opaque metal film layer.

[0052] In some examples, the near-field communication antenna 24 disposed on the first substrate 21 can also be a transparent structure to reduce potential reflections. Ambient light incident on the front of the display panel 20 may pass through the second substrate 23 and the display structure 22 to reach the first substrate 21, illuminating the near-field communication antenna 24 located on the surface of the first substrate 21 and causing reflection. The reflected ambient light exits from the front of the display panel 20, affecting the display effect of the display panel 20, such as causing reduced contrast and local bright spots. The transparent near-field communication antenna 24 has a low reflectivity, which can avoid adverse effects on the display effect.

[0053] For the near-field communication antenna 24 located on the surface of the second substrate 23 or in the display structure 22, a transparent structure is adopted, which can also reduce the reflection of ambient light by the near-field communication antenna 24 and avoid adverse effects on the display effect.

[0054] Figure 3 This is a top view schematic diagram of a display panel provided in an embodiment of this application, as shown below. Figure 3 As shown, the near-field communication antenna 24 extends along the edge of the second substrate 23 in the orthographic projection of the second substrate 23.

[0055] Even though the near-field communication antenna 24 is a transparent structure, resulting in minimal light reflection and obstruction, the difference in refractive index of the material means that some light emitted from the display panel 20 passes through the near-field communication antenna 24 while some does not. The light passing through the near-field communication antenna 24 undergoes some refraction, causing slight differences in the displayed image. By arranging the near-field communication antenna 24 along the edge of the second substrate 23, it is possible to avoid affecting the central area of ​​the displayed image, ensuring that the overall quality of the displayed image meets the design requirements.

[0056] Furthermore, the near-field communication antenna 24 is a coil structure, and the size of the coil opening affects the performance of the near-field communication antenna 24. Arranging the near-field communication antenna 24 along the edge of the second substrate 23 can increase the size of the near-field communication antenna 24 opening and improve its performance.

[0057] In some examples, the near-field communication antenna 24 can be a polygon.

[0058] For example, in this example, the near-field communication antenna 24 is rectangular. In other possible examples, the near-field communication antenna 24 can also be triangular, pentagonal, hexagonal, etc.

[0059] The surfaces of the first substrate 21, the second substrate 23, and the display structure 22 may have many other structures. The shape of the near-field communication antenna 24 is arranged in a relatively regular manner, which facilitates the layout of various structures and makes manufacturing easier.

[0060] In other examples, the near-field communication antenna 24 can also be circular.

[0061] The shape of the near-field communication antenna 24 can be consistent with the shape of the display panel 20, so as to make full use of the area of ​​the display panel 20 to arrange the near-field communication antenna 24 with a large opening.

[0062] In some examples, the first substrate 21 may be a substrate used to fabricate the display structure 22. The display structure 22 is typically fabricated using semiconductor processes. The display structure 22 is formed directly on the first substrate 21, and the near-field communication antenna 24 is also arranged on the first substrate 21. The display structure 22 and the near-field communication antenna 24 share a single substrate, which can reduce the number of substrates in the display panel 20 and help reduce the thickness of the display panel 20.

[0063] The display structure 22 may include at least one of a liquid crystal display structure, a light-emitting diode display structure, and an organic light-emitting diode display structure.

[0064] As an example, display structure 22 may include an organic light-emitting diode display structure.

[0065] Liquid crystal display structures, light-emitting diode (LED) display structures, and organic light-emitting diode (OLED) display structures all have multilayer structures. For example, an OLED display structure may include a gate insulating layer, an interlayer insulating layer, a pixel definition layer, an organic encapsulation layer, and an inorganic encapsulation layer. Because there are many film layers, some of these layers can be selected as carriers to fabricate the near-field communication antenna 24, thus integrating the near-field communication antenna 24 into the display structure 22.

[0066] For example, the near-field communication antenna 24 can be co-layered with a structure made of the same material in the display structure 22. For instance, the near-field communication antenna 24 can be co-layered with the anode layer in the organic light-emitting diode display structure. Using the same material to fabricate the near-field communication antenna 24 and the anode layer allows them to be formed through the same patterning process, saving on manufacturing steps.

[0067] In some examples, the second substrate 23 is a color filter substrate.

[0068] The color filter substrate may include a substrate and color blocks arrayed on the surface of the substrate, such as red, green, and blue color blocks, and may also include a black matrix distributed between adjacent color blocks. By arranging the near-field communication antenna 24 and the color blocks on the same substrate surface, the number of substrates in the display panel 20 can be reduced, which is beneficial for reducing the thickness of the display panel 20.

[0069] As an example, the near-field communication antenna 24 and the color blocks can be distributed on opposite sides of the substrate.

[0070] In other examples, the second substrate 23 may also be a touch substrate.

[0071] The touch substrate may include a substrate and touch electrodes distributed on the surface of the substrate. By arranging the near-field communication antenna 24 and the touch electrodes on the same surface of the substrate, the number of substrates in the display panel 20 can be reduced, which is beneficial to reducing the thickness of the display panel 20.

[0072] For example, the near-field communication antenna 24 and the touch electrode can be distributed on opposite sides of the substrate. Alternatively, the near-field communication antenna 24 and the touch electrode can be located on the same side of the substrate. The near-field communication antenna 24 and the touch electrode can be made of the same material, thus allowing them to be formed through the same patterning process, saving on manufacturing steps.

[0073] Figure 4 This is a schematic diagram of the internal structure of a smartwatch provided in an embodiment of this application, such as... Figure 4 As shown, the smartwatch also includes a motherboard 30, which is located in the mid-frame 10 and on the side of the first substrate 21 away from the display structure 22. A near-field communication antenna 24 is electrically connected to the motherboard 30.

[0074] The motherboard 30 is placed on the back of the display panel 20 and connected to the near-field communication antenna 24 to control the operation of the near-field communication antenna 24.

[0075] like Figure 4 As shown, the smartwatch also includes a wireless communication module 31, which includes at least one of a cellular mobile communication module, a Wi-Fi module, and a Bluetooth module. The wireless communication module 31 is located on the motherboard 30.

[0076] The functionality of the smartwatch is enriched by incorporating a wireless communication module 31 on the motherboard 30. This module enables cellular communication, such as 2G, 3G, 4G, and 5G. The Wi-Fi module enables Wi-Fi networks, such as 2.4GHz and 5.8GHz. The Bluetooth module enables Bluetooth wireless communication at a frequency of 2.4GHz.

[0077] In some examples, the smartwatch may also include a positioning module, which may be located on the motherboard 30. For example, it may be an L1 / L5 dual-frequency positioning module.

[0078] like Figure 4 As shown, the smartwatch may also include a battery 40. The battery 40 is located in the mid-frame 10, on the side of the motherboard 30 away from the display panel 20, and is connected to the motherboard 30.

[0079] Placing the battery 40 on the side of the motherboard 30 away from the display panel 20 facilitates its removal and replacement. When the battery 40 reaches the end of its lifespan or malfunctions, the back cover of the smartwatch can be opened to remove the battery 40 from the mid-frame 10 without disassembling the motherboard 30.

[0080] like Figure 4 As shown, the smartwatch may also include a base 50, which is located outside the middle frame 10. The base 50 is located on the side of the first substrate 21 away from the display structure 22, and the middle frame 10 is rotatably connected to the base 50.

[0081] Smartwatches typically have a camera function. By rotating the middle frame 10 and the base 50, the shooting angle of the smartwatch can be adjusted, making the smartwatch more convenient to use.
