In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

FIG. 2 is a schematic diagram of a four-layer structure of a touchpad of a notebook computer and a near-field communication coil, wherein the near-field communication coil 101 is disposed under a multilayer substrate 105, and the first layer of the multilayer substrate 105 is provided with an induction Conductor wires 1051, the second layer of the multilayer substrate 105 is provided with driving conductor wires 1052, the third layer of the multilayer substrate 105 is provided with a shield layer 201, and the fourth layer of the multilayer substrate 105 is provided with circuit traces 1054. Among them, the shielding layer 201 is a whole metal layer, so it can shield the interference between the induction conductor 1051, the driving conductor 1052 and the circuit trace 1054. However, since the shielding layer 201 is located in the near field communication coil 101 and touch Between the control conductor wire 1051 and the drive conductor wire 1052, the shielding layer 201 also shields the near-field communication coil 101 and thus the signal of the near-field communication coil 101 cannot penetrate the touch The control board is unable to properly sense external near field communication objects.

In order to design a touch panel device, the near field communication signal can penetrate the touch panel smoothly without affecting the use of the near field communication coil, and at the same time reduce the interference of the near field communication signal on the touch panel. The patterning design of the shielding layer of the control board device achieves the foregoing objective.

The present invention first confirms the design rules of the shielding layer that can pass the near field communication signal through the following different experiments to find the optimal shielding layer pattern design. Among them, the experiment is carried out with the structure shown in FIG. The copper foil 302 representing the shielding layer is placed under a glass substrate 303, and the copper foil 302 has a specific opening pattern design, and then the near field communication coil 101 is placed under the copper foil 302, and confirm the glass substrate 303 and the copper foil 302 Can completely cover the near-field communication coil 101, and then make a near-field communication object 304 approach the near-field communication coil 101 through the glass substrate 303 and the copper foil 302, to test whether the near-field communication coil 101 can be induced to confirm the near-field communication signal No penetrating copper foil 302. The experiments and results of different opening patterns are described below.

experiment one

As shown in FIG. 4, the opening pattern of the copper foil 302 representing the shielding layer is a plurality of slits 401. In this experiment, the length (L) and width (W) of the near-field communication coil 101 are defined as the near-field communication coil 101, respectively. The size of the long side and the short side, and L/W=55mm/34mm, the slit 401 is symmetrically extended by the center line 402 of the short side of the near field communication coil 101 along the width direction, and the length of each slit 401 Is a(mm). According to the data obtained from the experiment, the length (a) of the slit 401 of the copper foil 302 must be larger than the width (W) of the near-field communication coil 101 by a specific value (for example, 5 mm, 6 mm in this experiment) to be able to sense normally. Near field communication object 304. That is to say, this experiment shows that the length of the slit 401 opening in the shielding layer must be large enough, for example, a certain value larger than the width of the near-field communication coil 101 can normally induce near-field communication Object 304.

Experiment 2

As shown in FIG. 5, the opening pattern of the copper foil 302 representing the shielding layer is a plurality of slits 401. In this experiment, the length (L) and width (W) of the near-field communication coil 101 are defined as the near-field communication coil 101, respectively. The size of the long side and the short side, and L/W=55mm/34mm, the slit 401 is a long side that spans the near-field communication coil 101, and each slit 401 extends within the near-field communication coil 101 Is b (mm), the length of each slit 401 extending outside the near-field communication coil 101 is c=10 mm. It can be seen from the data obtained from the experiment that increasing the length b cannot normally sense the near field communication object 304, so it can be seen that the copper foil 302 representing the shielding layer is only open on one side of the near field communication coil 101 and cannot normally sense the near field communication object 304 . That is, this experiment confirms that the slit 401 opened in the shielding layer only crosses one side of the near-field communication coil 101 and cannot normally sense the near-field communication object 304.

Experiment 3

As shown in FIG. 6, the opening pattern of the copper foil 302 representing the shielding layer is a plurality of slits 401. In this experiment, the length (L) and width (W) of the near-field communication coil 101 are defined as the near-field communication coil 101, respectively. The size of the long side and the short side, and L/W=55mm/34mm, a part of the slit 401 of the plurality of slits 401 spans a long side of the near field communication coil 101, and the other part of the slit 401 spans Pass the other long side of the near field communication coil 101, and each slit 401 crosses the long side of the near field communication coil 101 with its central part, and the length of the slit 401 beyond the near field communication coil 101 is d( mm), and the diameter width (p) of the near-field communication coil 101 is about 4 mm. According to the data obtained from the experiment, the slit 401 exceeds the length d of the near-field communication coil 101 and is greater than the diameter width (p) of the near-field communication coil 101 (for example, 5 mm>4 mm of the experimental data), the near-field communication object 304 can be normally sensed Therefore, it can be seen that the slit 401 of the copper foil 302 representing the shielding layer on each side exceeds the length of the near field communication coil 101 by at least greater than the near field communication line The diameter width (p) of the loop 101, and at least the slits 401 on both sides of the near-field communication coil 101 are required to properly sense the near-field communication object 304. That is, this experiment confirms that the slit 401 opening in the shielding layer needs to cross the two sides of the near-field communication coil 101, and the slit 401 on each side must at least exceed the diameter of the near-field communication coil 101 and larger than the diameter of the near-field communication coil 101. a length of (p), in order to properly sense the near-field communication object 304, this experiment can also be inferred that the length of the slit 401 of the opening of the shielding layer in Experiment 1 also needs to be at least beyond the near-field communication coil 101 and greater than the near-field Only a length (p) of the diameter of the communication coil 101 can normally sense the near-field communication object 304.

Experiment 4

The conditions of Experiment 4 are the same as Experiment 1. When a=35mm, the near field communication object 304 cannot be sensed normally, but as shown in FIG. 7, an auxiliary slit 701 is added above and below the two adjacent slits 401 , It can normally sense the near field communication object 304, wherein the sum of the length of the two adjacent slits 401 beyond the near field communication coil 101 and the length of one of the auxiliary slits 701 connected is greater than the diameter of the near field communication coil 101 ( p). This experiment confirmed that the length of the slits extending to both sides of the near-field communication coil 101 can be achieved through auxiliary slits 701 in different directions.

Through the above experiments, the results of the shield layer pattern design rules are as follows:

(1) The slit in the opening of the shielding layer must cross the near-field communication coil and extend to both sides at least a length greater than the diameter of the near-field communication coil and the width of the near-field communication coil, and the length of the slit can be extended This is achieved through auxiliary slits in different directions.
