Description

  The present invention relates to a transparent touch panel device, an adjustment method thereof, and an electronic apparatus using the touch panel device.

  The touch panel device is widely used in various electronic devices, and includes a transparent substrate and a transparent touch panel film attached to the back side of the transparent substrate.

  Moreover, in order to prevent the sticking shift | offset | difference of the transparent touch panel film with respect to a transparent substrate, a 1st alignment mark is provided in a transparent substrate, a 2nd alignment mark is provided in a transparent touch panel film, and these 1st, 2nd alignment marks are attached. By confirming, the sticking shift | offset | difference of the transparent touch panel film with respect to a transparent substrate is prevented (the technique similar to this is described in the following patent document 1, for example).

JP 2011-100366 A

  As described above, if the transparent substrate is provided with the first alignment mark and the transparent touch panel film is provided with the second alignment mark, the positional deviation between the two can be reduced. Until the operation of the production apparatus stabilizes during a transition period such as model switching, a positional shift between the two occurs, and at that time, it is practically discarded as a defective product.

  That is, the transparent touch panel film is attached to the back side of the transparent substrate as described above, but since the transparent touch panel film is extremely thin and has a matrix pattern electrode or a diamond pattern electrode, Even if it is a defective product, if it is peeled off from the back side of the transparent substrate or is attached again, it will be damaged in shape and will not operate properly.

  Therefore, when the sticking shift | offset | difference of the transparent touchscreen film with respect to a transparent substrate generate | occur | produces, both a transparent substrate and a transparent touchscreen film will be discarded, and productivity will worsen by it.

  Accordingly, the object of the present invention is to increase productivity.

  In order to achieve this object, the present invention provides an operation area on the inner periphery, a transparent substrate provided with a detection area on the outer periphery of the operation area, and a transparent touch panel film attached to the back side of the transparent substrate. The transparent substrate has conductive first and second detection portions in a detection region on the back side thereof, and the second detection portion is in the X direction or Y direction with respect to the first detection portion. The transparent touch panel film is configured to have a position detection electrode in a portion facing the operation area and the detection area of the transparent substrate, thereby achieving an intended purpose. To achieve.

  As described above, the present invention includes a transparent substrate provided with an operation region on the inner periphery, a detection region provided on the outer periphery of the operation region, and the transparent touch panel film attached to the back side of the transparent substrate, and the transparent The substrate has conductive first and second detection units in a detection region on the back side thereof, and the second detection unit is first in the X direction or the Y direction with respect to the first detection unit. Since the transparent touch panel film has a position detection electrode in a portion facing the operation area and the detection area of the transparent substrate, productivity can be improved.

  That is, in the present invention, the transparent substrate has conductive first and second detection units in the detection region, and the second detection unit is in the X direction with respect to the first detection unit. Alternatively, the transparent touch panel film has a configuration in which the transparent touch panel film has a position detection electrode in a portion facing the operation area and the detection area of the transparent substrate. Thus, the positions of the first and second detection portions of the transparent substrate can be confirmed.

  That is, since the relative positional relationship (positional deviation) between the transparent substrate and the transparent touch panel film can be detected, the operation position information can be corrected by this positional relationship information.

  For this reason, even if a relative positional deviation between the transparent substrate and the transparent touch panel film occurs, it is not necessary to discard it, and as a result, productivity can be improved.

  In addition, since the relative positional relationship (positional deviation) between the transparent substrate and the transparent touch panel film can be detected and the operation position information can be corrected based on the positional relationship information, it is highly accurate with respect to the operation position. Become.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

(Embodiment 1)
In FIG. 1, in an automobile 1, a driver's seat 3 and a passenger seat 4 are disposed in front of a vehicle interior 2, a handle 5 is disposed in front of the driver's seat 3, and further on a side of the handle 5. An electronic device 6 is arranged.

  As shown in FIG. 2, the electronic device 6 includes a display 7 that displays an image and a speaker 8 that outputs sound.

  The display 7 is connected to the control unit 10 via the video control unit 9.

  Furthermore, an optical disc playback unit 11, a digital television playback unit 12, and a memory card playback unit 13 are connected to the control unit 10.

  A GPS 14 for performing car navigation and a memory 15 storing a map and a program are also connected to the control unit 10.

  Furthermore, a touch panel device 16 is connected to the control unit 10.

  In the above configuration, the display 7, the speaker 8, the video control unit 9, the optical disc playback unit 11, the digital television playback unit 12, the memory card playback unit 13, and the GPS 14 are well-known configurations, so that the description is not complicated. In addition, the description of these portions is simplified, and thereafter, the touch panel device 16 which is a characteristic portion of the present embodiment, the control unit 10 to which the touch panel device 16 is connected, and the memory 15 connected to the control unit 10. Will be described in detail.

  The touch panel device 16 is arranged on the front side of the display 7 as shown in FIG. 3, and the touch panel device 16 is positioned with respect to the main body case 17 of the electronic device 6 as shown in FIG. ing.

  In this state, when an operation unit (not shown) is displayed on the display 7, the operation is executed if the surface of the touch panel device 16 corresponding to the operation unit to be operated is touched. It has become.

  Such a relationship between the display 7 and the touch panel device 16 and the operation are well known, but the configuration of the touch panel device 16 is important in order to appropriately perform the operation.

  That is, as shown in FIG. 4, the touch panel device 16 has a configuration in which the transparent touch panel film 19 is attached to the back side of the transparent substrate 18 with the double-sided tape 20, and the transparent substrate 18 and the transparent touch panel film 19 are appropriately bonded. Otherwise, the positional relationship between the operation unit (not shown) displayed on the display 7 and the transparent touch panel film 19 is not appropriate, and as a result, proper operation cannot be performed.

  Even when the transparent touch panel film 19 cannot be properly bonded to the transparent substrate 18, the double-sided tape 20 is peeled off, and the transparent touch panel film 19 is again attached to the transparent substrate 18 via the double-sided tape 20. Therefore, it becomes difficult to attach them properly.

  Therefore, in the present embodiment, even if the transparent touch panel film 19 is pasted with respect to the transparent substrate 18, the relative positional relationship (positional deviation) is detected, and the operation positional information is corrected by this positional relationship information. It is what you do.

  Hereinafter, the structure of each part is demonstrated concretely.

First, a protective film 21 for preventing scattering is provided on the surface of the transparent substrate 18 as shown in FIG.

  Also, on the back side of the transparent substrate 18, as shown in FIGS. 4 and 5, a rectangular frame-like shape for dividing the transparent substrate 18 into an operation region 22 on the inner periphery and a detection region 23 on the outer periphery is provided. A non-transparent film 24 is provided.

  The non-transparent film 24 has adhesiveness on both sides, and is attached to the back side of the transparent substrate 18 by the adhesive force of the surface.

  In addition, using the non-transparent film 24, conductive detection units 25, 26, and 27 are provided at three corners on the back surface side of the rectangular transparent substrate 18.

  That is, the detection unit 27 is provided at a first interval in the X direction with respect to the detection unit 25 or 26, and the detection unit 26 is provided at a second interval in the Y direction with respect to the detection unit 25 or 27. It is the composition which was made.

  Further, these detection units 25, 26, and 27 are connected to the control unit 10 through conductive patterns 28.

  Next, the transparent touch panel film 19 has a configuration in which a plurality of transparent matrix pattern electrodes 30 and 31 are arranged at predetermined intervals in the X direction and the Y direction as shown in FIG. 6 on the front and back surfaces of the film 29 shown in FIG. (The matrix pattern electrode 30 may be provided on the surface of the film 29, and the matrix pattern electrode 31 may be provided on the surface of another film disposed on the back surface of the film 29).

  That is, as shown in FIG. 7, when the finger 32 is touched on the surface of the transparent substrate 18, the touched portion is detected.

  Specifically, in FIG. 7, the control unit 10 applies pulse signals to the plurality of matrix pattern electrodes 30 in order, and the plurality of matrix pattern electrodes 31 reads the signals in order. (A plurality of matrix pattern electrodes 31 may be configured to read signals simultaneously).

  When the finger 32 touches as described above, only the signal read by the leftmost matrix pattern electrode 31 in FIG. 7 becomes a low level signal while the signal is applied to the uppermost matrix pattern electrode 30 in FIG. With this, the control unit 10 determines which part is operated with the finger 32.

  A feature of the present embodiment is that the positional detection by the transparent touch panel film 19 is used to detect in what positional relationship the transparent touch panel film 19 is attached to the transparent substrate 18.

  For this purpose, the outer periphery of the transparent touch panel film 19 has a size that extends to the outer peripheral portion of the non-transparent film 24 shown in FIG. 5, and the matrix pattern electrodes 30 and 31 are arranged on the back side of the transparent substrate 18. It extends to the outer periphery of the conductive detectors 25, 26, 27 provided at the corners.

In the above configuration, at the time of manufacturing before factory shipment (including the adjustment process), first, the control unit 10 is in a state where the detection unit 25 is connected to the ground (the detection units 26 and 27 are not connected to the ground) ( Next, as described above, the control unit 10 applies pulse signals to the plurality of matrix pattern electrodes 30 in order (S3 in FIG. 10, S1 in FIG. 11). The matrix pattern electrode 31 sequentially reads the signal, detects the coordinates, and then writes the detected coordinates in the memory 15 (S2, S3, S4 in FIG. 11).

  Next, the control unit 10 sets the detection unit 26 to the ground (the detection units 25 and 27 are not connected to the ground) (S4 and S5 in FIG. 10), and then the control unit 10 as described above. Pulse signals are sequentially applied to the plurality of matrix pattern electrodes 30 (S6 in FIG. 10, S1 in FIG. 11), and the plurality of matrix pattern electrodes 31 read the signals in order to detect coordinates, and then The detected coordinates are written in the memory 15 (S2, S3, S4 in FIG. 11).

  Next, the control unit 10 makes the detection unit 27 connected to the ground (the detection units 25 and 26 are not connected to the ground) (S7 and S8 in FIG. 10). Next, as described above, the control unit 10 Pulse signals are sequentially applied to the plurality of matrix pattern electrodes 30 (S9 in FIG. 10, S1 in FIG. 11), and the plurality of matrix pattern electrodes 31 read the signals in order to detect coordinates, and then The detected coordinates are written in the memory 15 (S2, S3, S4 in FIG. 11).

  When the coordinate positions of the conductive detectors 25, 26, and 27 provided at the three corners on the back surface side of the transparent substrate 18 can be detected in this way (S10 in FIG. 10), the controller 10 records in the memory 15. From the coordinate positions of the detected units 25, 26, and 27, it is detected in what positional relationship the transparent touch panel film 19 is affixed to the transparent substrate 18 (S11 in FIG. 10), and the final deviation amount Then, the correction value is recorded in the memory 15 (S12 in FIG. 10).

  That is, when the transparent touch panel film 19 is appropriately attached to the transparent substrate 18, the coordinates of the detection unit 25 are (0, 500) and the coordinates of the detection unit 26 are (0, 0), for example, as shown in FIG. The coordinates of the detection unit 27 are (700, 500).

  However, as shown in FIG. 9, if the transparent touch panel film 19 is not properly attached to the transparent substrate 18, for example, the coordinates of the detection unit 26 are shifted from (0, 0) by tx in the X direction and ty in the Y direction. It becomes a state.

  Further, since the coordinates of the detection unit 25 are shifted from (0, 500) in the X direction and the Y direction, the inclination angle θ in FIG. 9 can be calculated.

  Since the detection unit 27 is also shifted in the X direction and the Y direction in the same manner as the detection unit 25, how the transparent touch panel film 19 is made with respect to the transparent substrate 18 from the amount of deviation of the detection units 25, 26, 27. It can be easily discriminated by a well-known simple mathematical formula (in this embodiment, the transparent touch panel film 19 with respect to the transparent substrate 18 from the amount of deviation of the detection units 25 and 26). It is possible to easily determine in what state the is attached.)

  Conventionally, when the transparent touch panel film 19 is affixed to the transparent substrate 18 as shown in FIG. 9, the transparent touch panel film 19 is a target for disposal. Since the amount is recorded in the memory 15, even in the state of FIG. 9, it is not a target for disposal, and the productivity is high.

That is, when the user touches the surface of the transparent substrate 18 of the touch panel device 16 with a finger 32 as shown in FIG. 7 in a normal use state (S1 and S2 in FIG. 12), the control unit 10 detects the coordinate position (FIG. 12). Next, the correction value is read from the memory 15 (S4 in FIG. 12), and then the detected coordinate position is corrected with the correction value (S5 in FIG. 12), and then the corrected coordinate position is determined. Returning to the control unit 10, the control unit 10 executes the operation that the user tried to execute (S 6 in FIG. 12).

  That is, the user operates while watching the display on the display 7 located on the back side of the touch panel device 16, and this operation can be executed reliably.

(Embodiment 2)
In the above embodiment, the transparent touch panel film 19 is provided with the matrix pattern electrodes 30 and 31 on the portion facing the operation region 22 and the detection region 23 of the transparent substrate 18 as shown in FIG. As described above, the diamond pattern electrodes 33 and 34 may be provided at portions of the transparent substrate 18 facing the operation region 22 and the detection region 23.

  That is, the matrix pattern electrodes 30 and 31 and the diamond pattern electrodes 33 and 34 are provided as examples of position detection electrodes, and the position detection electrodes may have other shapes.

  As described above, in the present invention, the operation area is provided on the inner periphery, the transparent substrate provided with the detection area on the outer periphery of the operation area, and the transparent touch panel film attached to the back side of the transparent substrate, The transparent substrate has conductive first and second detection units in the detection region on the back side thereof, and the second detection unit is arranged in the X direction or the Y direction with respect to the first detection unit. Since the transparent touch panel film has a configuration having position detection electrodes in a portion facing the operation region and the detection region of the transparent substrate, productivity can be improved.

  That is, in the present invention, the transparent substrate has conductive first and second detection units in the detection region, and the second detection unit is in the X direction with respect to the first detection unit. Alternatively, the transparent touch panel film has a configuration in which the transparent touch panel film has a position detection electrode in a portion facing the operation area and the detection area of the transparent substrate. Thus, the positions of the first and second detection portions of the transparent substrate can be confirmed.

  That is, since the relative positional relationship (positional deviation) between the transparent substrate and the transparent touch panel film can be detected, the operation position information can be corrected by this positional relationship information.

  For this reason, even if a relative positional deviation between the transparent substrate and the transparent touch panel film occurs, it is not necessary to discard it, and as a result, productivity can be improved.

  In addition, since the relative positional relationship (positional deviation) between the transparent substrate and the transparent touch panel film can be detected and the operation position information can be corrected based on the positional relationship information, it is highly accurate with respect to the operation position. Become.

  Therefore, utilization as various electronic devices is expected.
