Description

Technical Field

[0001] The utility model relates to the technical field of intelligent terminal devices, and particularly relates to an input sensor and a terminal device.

Background Art

[0002] With the improvement of the scientific and technological level, various intelligent terminal devices have become common tools in people's lives, such as smart phones, tablet computers, and laptop computers. The common interaction method of these intelligent devices is touch operation, that is, the input sensor is used to obtain the user's touch operation, so that the touch operation is converted into a control instruction of the terminal device.

[0003] In the prior art, in order to take into account both finger input and stylus input methods, an input sensor has emerged that integrates a capacitive sensor and an electromagnetic sensor. For example, the US Patent No. US6188391B1 discloses a two-layer capacitive touchpad and its manufacturing method, which has a layer of "diamond conductors" for capacitive touch and a layer of vertical electrodes for electromagnetic touch.

[0004] However, this input sensor results in more components, making the non-working area for laying traces and components larger, which inevitably increases the overall area of the input sensor. In some terminal devices with strict requirements for the occupied area of the input sensor, such as the touch screen of a smart phone and the touchpad of a laptop computer, it is required that the non-working area of the outer frame of the input sensor is smaller and the working area accounts for a larger proportion.

[0005] The input sensors in the prior art cannot meet the above requirements. Therefore, the above problems existing in the prior art remain to be improved.

Content of the Utility Model

[0006] The utility model provides an input sensor and a terminal device. By resetting the layout method of the traces of each planar layer in the input sensor, the non-working area of the input sensor is made smaller. At the same time, the entire input sensor can be integrated into a circuit board module, which saves more volume.

[0007] In the first aspect of the present utility model, an input sensor is provided for a touch input panel of a terminal device, which includes a plurality of planar layers stacked on top of each other. Each planar layer is respectively provided with a working area and a non-working area, and the non-working area is disposed around the outer edge of the working area; the plurality of planar layers include a capacitive touch layer, an electromagnetic touch layer, and at least one wiring layer.

[0008] In the second aspect of the present utility model, a terminal device is provided, which includes a processor, and the input sensor as described in the first aspect. Among them, the input sensor is used to obtain a user's touch operation; the processor is used to generate a control instruction according to the touch operation, and the control instruction is used to control the operation of the terminal device.

[0009] The input sensor provided by the present utility model includes a plurality of planar layers; the plurality of planar layers include a capacitive touch layer, an electromagnetic touch layer, and at least one wiring layer.

Since the connecting wire is disposed in the non-working area of each planar layer after passing through the via hole, the laying of the connecting wire is changed from horizontal laying to vertical laying, reducing the area occupied by the connecting wire in the non-working area of a single planar layer, and meeting the strict requirements of the terminal device for the occupied area of the input sensor.

Detailed implementation manners

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] Please refer to Figure 1 , as Figure 1 shown, the input sensor provided by the present utility model is used for the touch input panel of a terminal device, and includes a plurality of planar layers stacked. As shown in the figure, each planar layer is respectively provided with a working area 10 and a non-working area 20. The non-working area 20 is disposed around the outer edge of the working area 10. Preferably, the width of the non-working area 20 can be less than or equal to 2 mm; the plurality of planar layers include a capacitive touch layer 100, an electromagnetic touch layer 200, and at least one wiring layer 300. Among them,

[0016] As Figure 2 shown, a plurality of capacitive detection units 110 are arranged on the working area 10 of the capacitive touch layer 100, and the plurality of capacitive detection units 110 are connected by a first connection wire (not shown in the figure); as Figure 1 and Figure 3 shown, a plurality of electromagnetic wires 201 are provided on the working area 10 of the electromagnetic touch layer 200, and the plurality of electromagnetic wires 201 are connected into an electromagnetic loop by a connecting wire 202 between every two of them. Optionally, the electromagnetic loop can detect a touch operation by emitting a magnetic field or by receiving a magnetic field. The present utility model does not limit this. The connecting wire 202 is disposed in the non-working area 20; a via hole 21 is respectively provided in the non-working area 20 of each planar layer, and the first connection wire passes through the via hole 21 and is disposed on the wiring layer 300. At least a part of the connecting wire 202 passes through the via hole 21 and is disposed in the non-working area different from the electromagnetic touch layer 200.

[0017] In this embodiment, the capacitive touch layer 100 and the electromagnetic touch layer 200 are respectively used to meet two operation modes of handwriting input and stylus input. Among them, the first connection wire of the capacitive touch layer 100 is routed through a dedicated routing layer 300, which will not occupy the area of the non-working area 20. At the same time, for the connection wire 202 in the electromagnetic touch layer 200, the present invention utilizes the characteristics of multiple planar layers, and at least a part of the connection wire 202 is disposed in the non-working area different from the electromagnetic touch layer 200 after passing through the via hole 21. That is to say, there are two schemes: 1. All the connection wires 202 pass through the via hole 21 and are disposed in the non-working area of any one planar layer other than the electromagnetic touch layer 200. Or, 2. A part of the connection wires 202 pass through the via hole 21 and are disposed in the non-working area of the electromagnetic touch layer 200, and the other part of the connection wires 202 are disposed in the non-working area of other planar layers. In this way, it is equivalent to the non-working area 20 of each planar layer sharing the laying area of the connection wire 202, so that the area of the non-working area 20 of each planar layer can become smaller. Preferably, by adopting the scheme of the present invention, the width of the non-working area 20 can be less than or equal to 2 mm. Thus, the strict requirements of the terminal device for the occupied area of the input sensor are met.

[0018] As Figure 3 shows the setting method of the connection wire in the present invention. The middle square is the top view of the planar layer, and the four squares above, below, left and right of the square are the side views of the four sides. It can be seen the setting method of a single electromagnetic loop: the electromagnetic wire 201 is laid on the planar layer, the first end of the connection wire 202 is connected to the first end of the electromagnetic wire 201, the second end of the connection wire 202 penetrates into other planar layers through the via hole 21, and then returns to the original planar layer through another via hole 21 and is connected to the second end of the electromagnetic wire 201, thus forming an electromagnetic loop.

[0019] It should be noted that the electromagnetic loops in the electromagnetic touch layer 200 are often grouped in multiples. For this reason, in order to ensure the regular wiring of multiple groups of electromagnetic loops, the following scheme is further disclosed.

[0020] As Figure 3 shown, the input sensor includes a plurality of electromagnetic touch sub-units, and each group of the electromagnetic touch sub-units includes a preset number of the electromagnetic loops, wherein: the planar layers in which the connection wires 202 in each group of the electromagnetic touch sub-units are disposed after passing through the via holes 21 are the same.

[0021] In this embodiment, the plane layers where the connecting wires 202 in each group of electromagnetic touch sub-units are arranged after passing through the via holes 21 are the same, thus forming a regular and uniform arrangement. For example, each electromagnetic touch sub-unit includes three electromagnetic circuits, and the three electromagnetic circuits are respectively connected into a circuit through the first connecting wire 202, the second connecting wire 202, and the third connecting wire 202. At this time, the first connecting wire 202 passes through the via hole 21 and is arranged in the non-working area 20 of the capacitive touch layer 100, the second connecting wire 202 passes through the via hole 21 and is arranged in the non-working area 20 of the electromagnetic touch layer 200, and the third connecting wire 202 passes through the via hole 21 and is arranged in the non-working area 20 of the wiring layer 300. Thus, the connecting wires 202 of the three electromagnetic circuits in a group are respectively arranged in the non-working areas 20 of three different plane layers. The connecting wires 202 in each subsequent group of electromagnetic touch sub-units are arranged in the same manner. As a result, the overall wiring is more uniform, minimizing the increase in the thickness of the input sensor.

[0022] Preferably, when the number of electromagnetic circuits increases, the number of connecting wires 202 arranged in the non-working area 20 of each plane layer will inevitably increase. To avoid the increase in the area of the non-working area 20, the following preferred solution is provided.

[0023] As Figures 1 to 3 shown, the working area 10 is a polygon structure, and the non-working area includes partial non-working areas 20 corresponding to each side of the polygon; in each partial non-working area 20, the number of connecting wires 202 arranged on any one plane layer is less than or equal to two.

[0024] In this embodiment, the working area 10 is preferably rectangular. At this time, the non-working area 20 is set as a rectangular frame corresponding to the four sides of the rectangle, and the part corresponding to each side of the working area 10 in the rectangular frame is defined as a partial non-working area. In each partial non-working area, the number of connecting wires 202 arranged on any one plane layer is less than or equal to two. As a result, the number of connecting wires 202 arranged on the non-working area 20 of any one plane layer is set to be less than or equal to two. The width of the non-working area 20 is strictly controlled.

[0025] It should be noted that, in order to further reduce the area of the non-working area 20, in the solution of the present invention, the via holes 21 are arranged in a single row in each non-working area 20, which is specifically described as follows.

[0026] As Figure 2 and Figure 3 shown, the working area 10 is a polygon structure, preferably rectangular; the non-working area 20 includes partial non-working areas corresponding to each side of the polygon; in each partial non-working area, the corresponding via holes are arranged in a single row.

[0027] In this embodiment, the working area 10 and the non-working area 20 are arranged in the same way as described above. The non-working area 20 of each planar layer is provided with a single row of via holes 21 along the length direction of the side where it is located. The single row of via holes 21 includes a plurality of the via holes 21 arranged in a single row. Thus, the non-working area 20 is arranged along the outer sides of the rectangle. Among these outer sides, a single row of via holes 21 is arranged along the length direction of the side where it is located. Among them, each single row of via holes 21 includes a plurality of the via holes 21 arranged in a single row. Compared with the connection mode of arranging multiple rows of via holes 21 in the prior art, the single row of via holes 21 effectively reduces the width of the non-working area 20. On the basis of ensuring the smooth connection and wiring of the connection wires 202, the non-working area 20 is made narrower.

[0028] The present invention does not limit the specific structure of the electromagnetic touch layer 200. For the convenience of understanding, a preferred implementation solution is provided as follows.

[0029] As Figure 1 shown, the electromagnetic touch layer 200 includes a first sub-electromagnetic layer 210 and a second sub-electromagnetic layer 220. Among them, multiple electromagnetic wires 201 in the first sub-electromagnetic layer 210 are arranged in parallel along a first direction, and multiple electromagnetic wires 201 in the second sub-electromagnetic layer 220 are arranged in parallel along a second direction. The first direction and the second direction are different directions.

[0030] In this embodiment, the electromagnetic wires 201 of the two sub-electromagnetic layers are arranged along different directions respectively. Thus, the electromagnetic circuits formed on the two sub-electromagnetic layers are connected into a network, so that the touch operation can be accurately positioned. Preferably, the first direction and the second direction are orthogonal. Thus, the touch positions in the X-axis direction and the Y-axis direction can be detected respectively in the two directions.

[0031] It should be noted that there are various arrangement methods for the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220, including but not limited to: 1. The first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are arranged on two different substrates, or: 2. The first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are arranged on the same substrate. The following will be described in detail respectively.

[0032] 1. The first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are arranged on two different substrates.

[0033] In this embodiment, the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are respectively disposed on two different substrates; among them, the connecting wire 202 connected to the electromagnetic wire 201 on the first sub-electromagnetic layer 210 passes through the via 21 and is disposed in the non-working area 20 of any one planar layer; the connecting wire 202 connected to the electromagnetic wire 201 on the second sub-electromagnetic layer 220 passes through the via 21 and is disposed in the non-working area 20 of any one planar layer.

[0034] In this embodiment, the substrate refers to a circuit board for printed circuits. In this embodiment, the two sub-electromagnetic layers are respectively disposed on two different substrates, so that the electromagnetic wires 201 of the two electromagnetic layers do not come into contact and conduct, avoiding the occurrence of short-circuit situations. Further, the increase in the number of substrates also increases the number of non-working areas 20 where the connecting wires 202 can be disposed, which is beneficial to further reducing the area occupied by the non-working area 20 in a single planar layer.

[0035] 2. Dispose the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 on the same substrate.

[0036] In this embodiment, the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are disposed on the same substrate, and an insulating layer is disposed between the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220; among them, the connecting wire 202 passes through the via 21 and is disposed in the non-working area 20 of any one planar layer.

[0037] In this embodiment, the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are disposed on the same substrate by printing, and an insulating layer is also disposed between the two sub-electromagnetic layers, thereby preventing the electromagnetic wires 201 of the two electromagnetic layers from coming into contact and conducting. Via holes 21 are respectively provided in the planar layers where the first sub-electromagnetic layer 210 and the second sub-electromagnetic layer 220 are located, and the connecting wires of the two sub-electromagnetic layers are disposed in the non-working area 20 of any one planar layer after passing through the via holes 21. In this way, since the number of substrates is reduced, the overall thickness of the entire input sensor is thinner.

[0038] It should be noted that, in order to implement touch operations, the capacitive touch layer 100 and the electromagnetic touch layer 200 also need to be provided with corresponding processing devices, such as a micro integrated circuit (IC), electromagnetic resonance (EMR) wires, and corresponding capacitive resistors and other components. In the prior art, these components are generally disposed in the non-working area 20, which will inevitably lead to an increase in the area of the non-working area 20. To solve this problem, the present invention further provides the following solutions.

[0039] In this embodiment, as Figure 1 andFigure 4 As shown, the planar layer further includes a component mounting layer 400. The working area 10 of the component mounting layer 400 is used for mounting target components, and the target components are used to control the operation of the capacitive touch layer 100 and the electromagnetic touch layer 200. Optionally, the target components include, but are not limited to, ICs, EMR antennas, capacitive resistors, etc. The first connection wire and the connection wire 202 pass through the via hole 21 and then enter the working area 10 of the component mounting layer 400 to be connected to the target components.

[0040] In this embodiment, by providing a separate component mounting layer 400, it is avoided that the installation of components occupies the precious area of the non-working area 20. The arrangement of the components is adjusted from the original horizontal direction to the vertical direction, so that the proportion of the working area 10 of the input sensor is larger, and the occupied area of the non-working area 20 is saved.

[0041] It should be noted that the present invention does not limit the number and stacking order of the capacitive touch layer 100, the electromagnetic touch layer 200, the wiring layer 300, and the component mounting layer 400. For the convenience of understanding, a preferred embodiment is provided as follows.

[0042] Please refer to Figure 1 As shown in Figure 1 : The number of the planar layers is six. Among them,

[0043] The capacitive touch layer 100 is arranged on the first planar layer closest to the upper side. It should be noted that "closest to the upper side" refers to the side closest to the user. For example, the side closest to the outer surface of the screen of a smart phone, or the side closest to the outer surface of the touchpad of a laptop computer. In this way, through the capacitive touch layer 100, the touch operations input by the user are captured.

[0044] The second planar layer below the first planar layer is set as the first wiring layer 310, and the first connection wire is arranged on the first wiring layer 310. This "below" refers to the side away from the user. Arranging the first wiring layer 310 below the capacitive touch layer 100 is convenient for wiring the first connection wire.

[0045] The third planar layer and the fourth planar layer below the second planar layer are set as the electromagnetic touch layer 200.

[0046] The fifth planar layer below the fourth planar layer is set as the second wiring layer 320.

[0047] The sixth planar layer below the fifth planar layer is set as the component mounting layer 400, and the connection wires between the target components in the component mounting layer 400 are disposed on the second routing layer 320. Since components such as ICs, EMR antennas, capacitors, and resistors need to be interconnected within the component mounting layer 400, to avoid these wires occupying the area of the non-working area 20, the second routing layer 320 is separately provided. Optionally, the wires between the second routing layer 320 and the component mounting layer 400 are also connected after passing through the vias 21.

[0048] It should be noted that the above first planar layer to sixth planar layer can be integrated into a printed circuit board assembly (PCBA) through multi-layer printing, thereby reducing the overall thickness of the input sensor. As a result, the area of the non-working area 20 is reduced without increasing the overall thickness. Optionally, the first planar layer to sixth planar layer can also be respectively disposed in different PCBA, and the present utility model does not limit this.

[0049] The above provides a detailed description of the input sensor provided by the present utility model. On this basis, the present utility model further provides a terminal device, including a processor, and the above input sensor provided by the present utility model. Among them, the input sensor is used to obtain the touch operation of the user; the processor is used to generate a control instruction according to the touch operation. Optionally, the control instruction can be sent to the processor after being generated by the input sensor, or the input sensor only sends a touch signal to the processor, and the processor converts the touch signal into a control instruction. The present utility model does not limit this. The control instruction is used to control the operation of the terminal device.

[0050] In this embodiment, since the terminal device adopts the input sensor provided by the present utility model, the non-working area is smaller. For example, when the terminal device is a laptop computer, the input sensor is a touchpad, and the non-working area of the touchpad is smaller, so the touchpad can be made more compact as a whole, which is beneficial to making the laptop more lightweight and thin.

[0051] In summary, the input sensor provided by the present utility model includes multiple planar layers; the multiple planar layers include a capacitive touch layer, an electromagnetic touch layer, and at least one wiring layer. Among them, a plurality of capacitance detection units are arranged on the working area of the capacitive touch layer, and the plurality of capacitance detection units are connected by a first connection wire; a plurality of electromagnetic wires are provided on the working area of the electromagnetic touch layer, and are connected into an electromagnetic loop through a communication wire between two of them, and the communication wire is arranged in the non-working area; via holes are respectively provided in the non-working area of each planar layer, the first connection wire is arranged on the wiring layer after passing through the via hole, and the communication wire is arranged in the non-working area of any one of the planar layers after passing through the via hole. Since the communication wire is arranged in the non-working area of each planar layer after passing through the via hole, the arrangement of the communication wire is changed from horizontal arrangement to vertical arrangement, reducing the area occupied by the communication wire in the non-working area of a single planar layer, and meeting the strict requirements of the terminal device for the occupied area of the input sensor.

[0052] The above-described embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
