[0002] Currently, various smart wearable devices (such as smart watches, smart bracelets, etc.) have emerged on the market.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of an equivalent antenna touch screen provided by an embodiment of the present application, Figure 2 which is another schematic structural diagram of an equivalent antenna touch screen provided by an embodiment of the present application, wherein, Figure 1 the trace form of the shown equivalent antenna touch screen is a mesh trace, Figure 2 the trace form of the shown equivalent antenna touch screen is a serpentine trace; the equivalent antenna touch screen includes a touch screen 100, a TP cover plate 200, and a connection contact component 300;

[0035] Exemplarily, the TP cover plate 200 is arranged on the touch screen 100;

[0036] Exemplarily, a touch screen (TP, Touch Panel), also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as touches. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connecting devices according to a pre-programmed program, which can be used to replace a mechanical button panel and create vivid audio-visual effects through the liquid crystal display screen.

[0037] Exemplarily, the TP cover plate 200 includes a TP cover plate body 210 and TP cover plate traces 220, wherein the TP cover plate body 210 is matched and installed with the touch screen 100, the TP cover plate traces 220 are arranged on the TP cover plate body, and the TP cover plate traces are arranged between the touch screen and the TP cover plate body;

[0038] Exemplarily, the TP cover plate 200, i.e., the touch screen cover plate, includes a TP cover plate body 210 and TP cover plate traces 220. The TP cover plate body 210 can be made of transparent materials such as glass or indium tin oxide. The TP cover plate traces 220 are extremely thin metal wires printed on the TP cover plate body 210. When a user touches the TP cover plate 200, the TP cover plate traces 220 can feedback the touch position of the user to the corresponding intelligent wearable device.

[0039] Exemplarily, the connection contact component 300 includes a plurality of antenna contacts 310. The antenna contacts 310 are electrically connected to the TP cover plate traces 220 and are connected to a preset antenna.

[0040] In some embodiments, the TP cover plate 200 of the equivalent antenna touch screen includes a TP cover plate body 210 and TP cover plate traces 220, where the TP cover plate body 210 is covered and installed on the touch screen 100, and the TP cover plate traces 220 are disposed between the touch screen 100 and the TP cover plate body 210. Through the plurality of antenna contacts 310 of the connection contact component 300, an electrical connection between the TP cover plate traces 220 and the preset antenna is realized, and the TP cover plate traces 220 are used as the receiving and transmitting conductors of the preset antenna for receiving and transmitting signals. Thus, by sharing the traces of the preset antenna and the TP cover plate traces on the TP cover plate, the equivalent antenna touch screen can greatly increase the antenna receiving area and design area of the preset antenna, achieving the technical effect of improving the antenna performance.

[0041] Exemplarily, the connection contact component 300 further includes a main radio frequency antenna contact 311. The preset antenna includes a main board radio frequency antenna, and the main radio frequency antenna contact 311 is respectively connected to the TP cover plate traces 220 and the main board radio frequency antenna.

[0042] Exemplarily, through the main radio frequency antenna contact 311, the main board radio frequency antenna is connected to the TP cover plate traces 220, so that the TP cover plate traces 220 are used as the receiving and transmitting conductors of the main radio frequency antenna.

[0043] Exemplarily, the connection contact component 300 further includes a WCN antenna contact 312. The preset antenna includes a WCN antenna, and the WCN antenna contact 312 is respectively connected to the TP cover plate traces 220 and the WCN antenna.

[0044] Exemplarily, through the WCN antenna contact 312, the WCN antenna is connected to the TP cover plate traces 220, so that the TP cover plate traces 220 are used as the receiving and transmitting conductors of the WCN antenna.

[0045] In some embodiments, the WCN antenna is an antenna for receiving and transmitting signals, mainly used in the radio frequency front-end circuit. Technically, the WCN antenna is connected to the WCN transceiver through the first radio frequency path, used to receive GPS signals, and transmits the received signals to the WCN transceiver through this path. This configuration effectively improves the directivity of GPS signals, thereby improving the signal reception quality. In mobile terminal devices, when the GPS positioning function is activated, the WCN antenna and the diversity receiving antenna work simultaneously to enhance the signal reception effect.

[0046] Exemplarily, the connection contact component 300 further includes a ground contact 320. The ground contact 320 is led out through the TP cover board trace 220, and the ground contact 320 is electrically connected to a preset main board; the preset main board can be the main board of a smart wearable device, and the number of ground contacts 320 can be multiple, corresponding to and connected to the main radio frequency antenna contacts 311 or WCN antenna contacts 312 that match, forming an antenna trace.

[0047] Exemplarily, for the equivalent antenna touch screen provided in the embodiments of the present application, the main radio frequency antenna of the preset main board can be divided into a high and intermediate frequency part and a low frequency part. Among them, the high and intermediate frequency antenna is shorter in length, and the low frequency antenna is longer in length; it should be noted that the positions of any main radio frequency antenna contacts, WCN antenna contacts, and ground contacts in the embodiments of the present application are all led out from the TP cover board trace 220 and connected to the preset main board.

[0048] From Figure 1 it can be seen that the trace of the lower part of the dotted line is the trace of the main radio frequency antenna, and the trace of the upper part of the dotted line is the trace of the WCN antenna.

[0049] In some implementation scenarios, from Figure 1 it can be seen that there are two main radio frequency antenna contacts 311: the first main radio frequency antenna contact 3111 and the second main radio frequency antenna contact 3112; the trace of the lower part of the dotted line is the trace of the main radio frequency antenna. If its power supply is the first main radio frequency antenna contact 3111 among the main radio frequency antenna contacts 311, that is, it can complete the separation of a high and intermediate frequency antenna and a low frequency antenna (at this time, the dotted line on the left side of the first main radio frequency antenna contact 3111 is the high and intermediate frequency antenna, and the dotted line on the right side of the first main radio frequency antenna contact 3111 is the low frequency antenna); similarly, if its power supply is the second main radio frequency antenna contact 3112 among the main radio frequency antenna contacts 311, it can also complete the separation of a high and intermediate frequency antenna and a low frequency antenna (at this time, the dotted line on the right side of the second main radio frequency antenna contact 3112 is the high and intermediate frequency antenna, and the dotted line on the left side of the second main radio frequency antenna contact 3112 is the low frequency antenna).

[0050] In other words, in Figure 1Among them, the length of the WCN antenna is fixed. From the WCN antenna contact to the GND (ground contact), it can be similar to Figure 1 the selection in; while the main RF antenna has two matching GNDs (ground contacts). The contact point of the main RF antenna is located between the two GNDs, and it is ensured that the main RF antenna is divided into two parts, one long and one short.

[0051] Exemplarily, as Figure 2 shown, it is a schematic diagram of the approximate routing of the serpentine routing dial; in Figure 2 it, there are three ground contacts 320. The serpentine routing of the upper dotted line is respectively connected to one ground contact 320 and the WCN antenna contact 312; the serpentine routing of the lower dotted line is respectively connected to two ground contacts 320 and the main RF antenna contact 312, and the main RF antenna contact 312 is located between the two ground contacts 320, dividing the main RF antenna into two parts, one long and one short.

[0052] Exemplarily, the TP cover board routing 220 is serpentine routing or mesh routing.

[0053] Exemplarily, the TP cover board body 210 includes a single-layer transparent cover board, and the TP cover board routing 220 is arranged between the touch screen 100 and the single-layer transparent cover board.

[0054] In some embodiments, the TP cover board body 210 usually has only a single-layer transparent cover board; this single-layer transparent cover board is divided into two sides. One side is the side away from the touch screen 100, and this side is a flat plane; the other side is the side close to the touch screen 100, and this side is printed with extremely fine metal wires (such as copper wires, etc.) through processes such as laser engraving to form serpentine routing or mesh routing;

[0055] Optionally, the TP cover board body 210 is a transparent cover board printed with extremely fine metal wires (i.e., the TP cover board routing 220), and its material can be transparent materials such as glass and indium tin oxide, and can be one layer, two layers or multiple layers; when the cover board structure of the TP cover board body 210 is one layer, its TP cover board routing 220 is located on the side of the TP cover board body 210 close to the touch screen 100, and at this time, the light transmittance and sensitivity of the equivalent antenna touch screen are the best; when the cover board structure of the TP cover board body 210 is two layers or multiple layers, its TP cover board routing 220 can be located between any two adjacent transparent cover boards, and at this time, the light transmittance and sensitivity of the equivalent antenna touch screen decrease with the increase of the layer structure.

[0056] Exemplarily, the TP cover board body includes multiple layers of transparent cover boards, and the multiple layers of transparent cover boards are arranged in parallel and stacked, and the TP cover board routing is arranged between two adjacent transparent cover boards.

[0057] Exemplarily, the transparent cover board is a glass transparent cover board or an indium tin oxide transparent cover board.

[0058] Exemplarily, the antenna contact 310 is a pad mechanism; a position on the TP cover plate trace 220 that requires a contact is led out, that is, a pad is led out and welded at the position on the TP cover plate trace 220 that requires a contact.
