Abstract
Provided is a touch panel device which can detect the operation amount reliably and has low cost. A touch panel device (1) is provided with: a capacitive touch panel (4) provided with electrode patterns (20(21, 22)); and a rotation operation unit (6) which is provided with a counter electrode (10) facing the electrode pattern and is rotatably attached to the touch panel. The electrode pattern is composed of a first electrode (21) (parasitic capacitance (ZP1)) and a second electrode (22) which are insulated from each other and have a circular shape. The first electrode is formed of a plurality of small patterns (21a) (parasitic capacitances (ZP2)) insulated from each other. When the rotation operation part is rotated, capacitance change occurs between the counter electrode and the touch panel, and the position of the counter electrode can be detected. Since the rotation operation portion is non-conductive, it is not related to the capacitance of the human body, and since the detection of the position depends on the parasitic capacitance of the electrode pattern, the accuracy is high.
Description
Technical Field
The present invention relates to a touch panel device that detects an operation of a rotary operation unit attached to a capacitive touch panel by an electrode pattern of the touch panel, and more particularly, to a touch panel device that can reliably detect an operation of a rotary operation unit regardless of a capacitance of a person touching the rotary operation unit.
Background
Various electronic devices having a function of controlling various physical quantities are provided with an adjustment member for an operator to adjust the physical quantities with fingers. Such adjustment members are known: the operator pinches a knob-type rotation operation portion (operation knob) to be rotated with a finger. For example, in order to perform operations of volume adjustment in audio equipment and temperature adjustment in air conditioning, a known variable resistor and a rotary encoder are provided as electronic components for adjustment in a volume or temperature adjustment circuit of each equipment, and a rotary operation unit is attached to these rotary shafts. The operator can adjust the volume or temperature by rotating the rotary operation part by pinching the rotary operation part with fingers. Further, the variable resistor is an electronic component that converts a change in mechanical position into a change in resistance value and outputs as an analog electric signal, and is also called a potentiometer. In addition, the rotary encoder is a sensor that outputs a rotational displacement of an input shaft as a digital signal using a built-in mesh disk.
In addition, in addition to a knob-type adjustment member using a variable resistor or the like, a capacitive touch panel as shown in fig. 5 is known as an adjustment member. In this touch panel, a touch key 101 including a plurality of electrode patterns 100 is provided on the lower surface side of a cover glass constituting a part of the panel, and only the touch key 101 is shown in fig. 5, and the structural members of the panel and the like are omitted. In the example of fig. 5, the electrode patterns 100 of the touch key 101 are linearly arranged in the operation direction, for example, if the touch key 101 is an operation portion for volume adjustment in an acoustic apparatus, as conceptually shown in fig. 5, if an operator touches the touch key 101 with a finger through a cover glass and performs a slide gesture operation in a direction indicated by an arrow, the touch panel detects the position of the electrode pattern 100 that the finger approaches, and thus the apparatus adjusts the volume according to the position of the electrode pattern 100 detected by the touch panel. For example, when a finger is slid in the right direction of the arrow, the sound volume is increased, and when a finger is slid in the left direction of the arrow, the sound volume is decreased.
Disclosure of Invention
Problems to be solved by the invention
In the case where the variable resistor and the adjustment member of the rotary operation unit are coupled to the shaft of the rotary encoder, the rotary operation unit is operated by rotating, and therefore, even if the rotary operation unit is not directly visually recognized, the operation amount can be easily and intuitively understood by only the feeling of a finger. However, since the variable resistor and the rotary encoder have a rotating portion, there is a problem that the electronic components have wear life and are expensive.
In addition, in the case where the adjustment member is a touch panel, the adjustment operation is performed by a finger of the operator through a slide gesture operation. Therefore, there is a problem that it is difficult to intuitively understand the operation amount only by the feeling of the finger since the position of the touch key touched with the finger is not known unless the touch key and the finger are directly visually recognized. In particular, in the case of an in-vehicle electronic device, since it is not preferable to look at the touch panel safely during driving, there is a problem that it is difficult to grasp the operation amount particularly during driving, and the operation itself is liable to become unstable.
The present invention has been made to solve the above-described problems of the related art, and an object of the present invention is to provide a touch panel device which uses a touch panel, is low in cost, can intuitively grasp an operation amount, and can reliably detect the operation amount.
Technical scheme for solving problems
In an exemplary embodiment of the present invention, a touch panel device is provided. The touch panel device includes: a capacitive touch panel having an electrode pattern; and a rotation operation unit which is provided with a counter electrode facing the electrode pattern and is rotatably attached to the touch panel.
In the touch panel device according to the embodiment, the electrode pattern is formed of a circular first electrode and a circular second electrode, the first electrode and the second electrode are arranged to be adjacent to each other in an insulated manner, at least one of the first electrode and the second electrode is grounded, and the counter electrode is arranged to face the electrode pattern so as to cross the first electrode and the second electrode in a diameter direction.
In the touch panel device according to the above-described embodiment, in the touch panel device according to the second aspect of the present invention, one of the first electrode and the second electrode is separated and insulated from each other in the circumferential direction, and at least the other is grounded.
In the touch panel device of the embodiment, a plurality of the counter electrodes are provided.
Effects of the invention
According to the touch panel device of the above embodiment, when the operator rotates the rotary operation unit by pinching it with a finger, the counter electrode of the rotary operation unit moves relative to the electrode pattern of the touch panel, and thus a capacitance change occurs between the counter electrode and the touch panel, and the position where the capacitance change occurs can be detected by the touch panel. In the touch panel device based on the position detection principle, if a configuration that is not easily related to the capacitance of the human body that operates the rotation operation portion is adopted, for example, if the rotation operation portion is formed of a non-conductive material, a current is not easily flowed through the human body that operates the rotation operation portion, and therefore, the position detection by the change in the detection capacitance described above depends mainly on the parasitic capacitance on the electrode pattern side of the touch panel, and therefore, the position detection operation is reliable and the accuracy is improved.
In addition, according to the touch panel device of the above embodiment, when the operator rotates the rotation operation unit by pinching it with a finger, the counter electrode disposed across the first electrode and the second electrode moves along the circular first electrode and second electrode of the touch panel. When the position of the counter electrode with respect to the first electrode and the second electrode is changed in the circumferential direction by this action, the parasitic capacitance of the first electrode and the parasitic capacitance of the second electrode are combined at the changed position, and the capacitance between the counter electrode and the touch panel is changed before and after the movement, so that the position where the change occurs can be detected by the touch panel. In this way, in the touch panel device, the position of the counter electrode is detected by detecting a change in capacitance resulting from the combination of the parasitic capacitance of the first electrode and the parasitic capacitance of the second electrode, and therefore, the detection operation of the position is reliable and the accuracy is improved regardless of the capacitance of the human body contacting the rotational operation portion. That is, if the rotation operation portion is formed of a non-conductive material, no current flows in the human body operating the rotation operation portion regardless of the capacitance of the human body, and even if the rotation operation portion is formed of a conductive material, the current flowing in the human body operating the rotation operation portion is relatively small, and therefore, the influence of the capacitance of the human body is still small. Therefore, the operation can be performed both by bare hands and by wearing thick gloves.
In addition, according to the touch panel device of the above embodiment, since one of the first electrode and the second electrode is formed to be spaced apart in the circumferential direction and insulated from each other, the position in the circumferential direction of the counter electrode can be detected with precision.
In addition, according to the touch panel device of the above embodiment, if the change in capacitance generated between each of the plurality of counter electrodes and the electrode pattern is made different by appropriately setting the arrangement in the circumferential direction of the plurality of counter electrodes, the position in the circumferential direction of the counter electrode can be detected more precisely, and the rotational direction of the counter electrode can also be detected.

Detailed Description
A first embodiment of the present invention will be explained with reference to fig. 1 to 3.
As shown in fig. 1, a touch panel device 1 of the present embodiment includes: a display panel 2; a capacitive touch panel 4 that is attached to the upper surface side of the display portion of the display panel 2 with a light-transmissive adhesive sheet 3; a light-transmitting cover glass 5 bonded to the upper surface of the touch panel 4 with a light-transmitting adhesive sheet 3; a rotation operation portion 6 (operation knob) is rotatably attached to the upper surface of the cover glass 5. The display principle and the display content of the display panel 2 are not limited. A decorative layer 7 of black or the like is provided on the peripheral edge portion of the lower surface of the cover glass 5, and the display area of the display portion of the display panel 2 is divided into a frame shape.
According to this touch panel device 1, the display of the display panel 2 can be viewed from the front surface side of the cover glass 5 through the touch panel 4, and the electrode pattern of the touch panel 4 located directly below the rotation operation unit 6 can be selectively operated by operating the rotation operation unit 6 while visually recognizing the display.
As shown in (a) and (b) of fig. 2, the rotation operation portion 6 is cylindrical. The rotation operation portion 6 is made of a non-conductive material such as a non-conductive resin or a conductive material whose surface is processed to be non-conductive. The rotation operating portion 6 is formed with an anti-slip pattern 8 composed of a plurality of grooves parallel to a generatrix (a line parallel to the central axis on the cylindrical circumferential surface). A shaft hole 9 parallel to the central axis of the cylindrical shape is formed at the center of the rotational operation portion 6. The shaft hole 9 is not opened on the upper surface but opened in the center of the bottom surface. A rectangular counter electrode 10 is provided on a part of the bottom surface, and is in contact with the edge of the shaft hole 9 and the outer circumference of the rotation operating portion 6. The counter electrode 10 is fitted into the bottom surface of the rotating operation part 6, and the surface of the counter electrode 10 and the bottom surface of the rotating operation part 6 are the same surface.
As will be described later in detail, the counter electrode 10 is disposed opposite to the electrode pattern 20 (see fig. 3 c) of the touch panel 4. Further, as an example of the size, the diameter of the shaft hole 9 is the diameter of the rotational operation portion 6 (about 40%). Since the dimension (width) of the counter electrode 10 in the circumferential direction (rotation direction) is approximately (one twentieth) of the circumference of the rotation operation unit 6, the rotation angle is approximately (15 degrees to 20 degrees) when the rotation operation unit 6 is rotated by rotating the width of the counter electrode 10.
As shown in fig. 2 (c), a mounting bracket (stay)11 as a support shaft of the rotation operation portion 6 is provided on the surface of the cover glass 5. That is, two fixing bars 12 are provided so as to protrude from the bottom of the mounting bracket 11, two recesses 13 are provided on the surface of the cover glass 5, and the mounting bracket 11 can be vertically fixed to the surface of the cover glass 5 by applying an adhesive to the inside of the recesses 13 (and, if necessary, the surface of the cover glass 5 between the recesses 13 and the recesses 13) and inserting the fixing bars 12 into the recesses 13.
As shown in fig. 2 (c), the mounting bracket 11 has a substantially cylindrical shape in which the tip of the upper portion is slightly tapered. At least the upper portion of the mounting bracket 11 is hollow, and its outer diameter is slightly larger than the inner diameter of the shaft hole 9 of the rotational operation portion 6. The upper portion of the mounting bracket 11 is divided into a plurality of plate portions 15 from the upper end portion to a substantially central portion thereof by a plurality of longitudinal grooves 14 formed substantially parallel to the central axis of the substantially cylindrical shape. The lower portion of each plate portion 15 is integral, but the upper end portion is an independent free end, and therefore can be elastically deformed in the radial direction. In addition, the length of the mounting bracket 11 is substantially the same as the length of the shaft hole 9 of the rotational operation portion 6. Therefore, when the rotation operation portion is attached to the attachment bracket 11 such that the attachment bracket 11 of the cover glass 5 is inserted into the shaft hole 9 of the rotation operation portion 6, the plate portion 15 of the attachment bracket 11 is slightly displaced inward and contacts the inner surface of the shaft hole 9 by the elastic force, and the bottom surface of the rotation operation portion 6 contacts the surface of the cover glass 5.
Further, since the bent portion 16 is provided at the middle portion of each plate portion 15 of the mounting bracket 11 and the locking portion, not shown, is provided at a critical position on the inner peripheral surface of the shaft hole 9 of the rotation operating portion 6, when the mounting bracket 11 is inserted into the shaft hole 9 of the rotation operating portion 6, the bent portion 16 is locked to the locking portion of the shaft hole 9, and therefore, the rotation operating portion 6, which is mounted, is not easily detached from the mounting bracket 11 even if it is pulled.
In this way, when the rotation operation portion 6 is held between fingers and rotated in a state where the rotation operation portion 6 is attached to the attachment bracket 11, the rotation operation portion 6 can be rotated with respect to the attachment bracket 11. By this operation, the counter electrode 10 located on the bottom surface of the rotation operation portion 6 moves in the circumferential direction along the surface of the cover glass 5.
As shown in fig. 3, the rotation operating portion 6 faces the electrode pattern 20 of the touch panel 4 located below the cover glass 5. That is, as shown in fig. 3 (a) and (b), the counter electrode 10 is provided on the bottom surface of the rotation operation portion 6, and as shown in fig. 3 (c), the counter electrode 10 faces the electrode pattern 20 formed of the circular first electrode 21 and the circular second electrode 22 provided on the touch panel 4.
Fig. 3 (c) shows the positional relationship of the electrode pattern 20 and the counter electrode 10 by projecting the counter electrode 10 on the plan view of the electrode pattern 20, while showing the electrode pattern 20 of the touch panel 4. As shown in fig. 3 (c), each of the first electrode 21 and the second electrode 22 is a ring-shaped pattern concentric with the mounting bracket 11, the first electrode 21 is on the outer side, and the second electrode 22 is on the center side. The first electrode 21 and the second electrode 22 have the same radial dimension and are insulated from each other. The outer first electrode 21 is formed of a plurality of (6 in the figure) small patterns 21a divided in the circumferential direction. The small patterns 21a are formed in a shape like a curved arrow having a convex triangle at one end and a concave triangle at the other end, and are combined with each other while facing in the same direction, thereby forming the annular first electrode 21 as a whole. The small patterns 21a are insulated from each other. The second electrode 22 is a single ring-shaped electrode pattern.
In (c) in fig. 3, each small pattern 21a of the first electrode 21 and the second electrode 22 has a parasitic capacitance ZP1, ZP2, respectively, as visualized with the impedance symbol Z. In the same figure, the parasitic capacitance ZP1 of the small pattern 21a of the first electrode 21 shows only one small pattern 21a, and actually each of the 6 small patterns 21a has a parasitic capacitance ZP 1.
The parasitic capacitance is not caused only by a specific component mounted but is generated by an interaction caused by a physical structure inside an electronic component or inside an electronic circuit, and is not a capacitance component expected by a designer. Therefore, fig. 3 (c) shows that both the first electrode 21 (small pattern 21a) and the second electrode 22 are grounded through the parasitic capacitances ZP1, ZP2, respectively, but only the second electrode 22 is grounded as an actual circuit (connected to GND) in the present embodiment.
Here, the term "grounded" means that the electrode (electrode pattern 20) is connected to a potential reference point by an electric conductor, and the Ground (GND) is often used as a typical potential reference point, but it also includes a case where a wiring, a case, some electronic components having impedance, and the like are interposed during grounding. In short, the electrode pattern 20 may be in a state where electric charges flow out from the electrode.
According to the touch panel device 1, when the operator rotates the rotational operation unit 6 by pinching it with a finger, the counter electrode 10 of the rotational operation unit 6 moves relative to the electrode pattern 20 of the touch panel 4, and a capacitance change occurs between the counter electrode 10 and the touch panel 4, and the position where the change occurs can be detected by the touch panel 4. Specifically, by rotating the rotating operation unit 6, the counter electrode 10 arranged across the first electrode 21 and the second electrode 22 in the diameter direction moves along the circular first electrode 21 and second electrode 22 of the touch panel 4 in a state where the counter electrode 10 faces the electrode pattern 20, and the positions of the first electrode 21 and second electrode 22 are changed in the circumferential direction. When the position of the counter electrode 10 changes, the capacitance ZS in the system of the touch panel 4 becomes a value in which the parasitic capacitance ZP1 of the first electrode 21 and the parasitic capacitance ZP2 of the second electrode 22 are combined by the counter electrode 10. Since the capacitance between the counter electrode 10 and the touch panel 4 changes before and after the movement due to the difference between this value and the capacitance ZS before the movement, the position at which this change occurs can be detected by the touch panel 4.
In this way, in the touch panel device 1, the position of the counter electrode 10 is detected by detecting a change in capacitance resulting from a combination of the parasitic capacitance of the first electrode 21 and the parasitic capacitance of the second electrode 22. Therefore, the position detection operation is reliable and the accuracy is improved regardless of the capacitance of the human body H in contact with the rotation operation unit 6. That is, since the rotation operation portion 6 of the touch panel device 1 is made of a non-conductive material, no current flows through the human body H that operates the rotation operation portion 6, and the capacitance of the human body H is not involved in the position detection of the counter electrode 10. Therefore, the operation can be performed in any case, regardless of whether the user wears gloves having a large thickness. Such a high degree of freedom of use is particularly advantageous when the vehicle-mounted device is mounted on the vehicle because the driver is supposed to wear gloves during driving of the vehicle. Further, in this touch panel device 1, even if the rotation operation portion 6 is formed of a conductive material, the current flowing through the human body H that operates the rotation operation portion 6 is relatively small, and therefore, the influence of the capacitance of the human body H is still small.
A second embodiment of the present invention will be described with reference to fig. 4.
Fig. 4 (a) is a perspective view of the rotational operation unit 6, and corresponds to fig. 3 (a) of the first embodiment. Fig. 4 (b) shows a projection image of the electrode pattern 20 and the counter electrode 10, corresponding to fig. 3 (c). As is apparent from fig. 4, the touch panel device 1a of the present embodiment is different from the touch panel device 1 of the first embodiment in the number of counter electrodes 10. Other structures are the same as those of the first embodiment, and the description of the first embodiment is referred to avoid redundancy.
As shown in fig. 4 (b), the touch panel device 1a of the present embodiment includes two counter electrodes 10 and 10. The two counter electrodes 10 and 10 are arranged at positions slightly shifted from the symmetrical positions 180 degrees apart from each other in the rotational direction of the rotational operation portion 6, and in the specific example shown, are in a positional relationship shifted from the symmetrical positions by about (25 to 30 degrees). Since the first electrode 21 is formed of 6 small patterns 21a having the same shape, if the two counter electrodes 10, 10 are spaced apart by 180 degrees in the rotational direction, the following state is achieved: the positions of the small patterns 21a facing the two opposite electrodes 10, 10 are the same as each other, and the two opposite electrodes 10, 10 are projected at the same position on different small patterns 21a of the same shape. However, the two counter electrodes 10 and 10 of the present embodiment are arranged so as to be shifted from the symmetrical positions, and the phases overlapping with respect to the small pattern 21a are different from each other.
In the touch panel device 1a of the present embodiment, if the rotational operation unit 6 is held and rotated by a finger, the 2 counter electrodes 10, 10 of the rotational operation unit 6 are moved relative to the electrode pattern 20 of the touch panel 4, respectively, and the capacitance between the 2 counter electrodes 10, 10 and the touch panel 4 changes, but since the change differs among the 2 counter electrodes 10, the detection accuracy of the positions of the counter electrodes 10, 10 is higher than that of the first embodiment, and the rotational direction of the rotational operation unit 6 can also be detected. Further, if the phases superposed on the small patterns 21a are different, the detection accuracy can be further improved by providing 3 or more counter electrodes 10.
As shown in fig. 1, the touch panel devices 1 and 1a of the above-described embodiments are configured such that the touch panel 4 is attached to the display panel 2, the cover glass 5 is attached to the touch panel 4, and the rotation operation unit 6 is provided on the upper surface of the cover glass 5. However, the touch panel 4 and the cover glass 5 may be integrated into a simple structure as described below. That is, in the first embodiment, the lower surface of the cover glass 5 provided with the decorative layer 7 is formed with an electrode pattern in a region inside the decorative layer 7, and the electrode pattern is covered with an insulating protective film to form a touch panel. If a touch panel having such a single-piece structure is attached to the display panel 2 and the rotation operation unit 6 is provided on the upper surface of the touch panel, a touch panel device having a simpler structure can be formed.
