Description

  The present invention relates to a touch panel device that executes processing according to an input position on a touch panel, and more particularly, to a touch panel device having a function of preventing erroneous input to a touch panel unintended by a user.

  Conventionally, as a mobile terminal such as a tablet or a smartphone, a touch panel device that receives an input from a user with a touch panel is used. In the touch panel device, an image is displayed on the touch panel, and the touch panel detects a contact position when a user who has viewed the image touches the touch panel. The touch panel detects the contact position, and the touch panel device executes processing according to the content of the image displayed at the contact position. In addition, some touch panels with high sensitivity can be input by approaching a close range without directly touching.

  In the touch panel device, a foreign object may accidentally approach or touch the touch panel, and an erroneous input unintended by the user may occur. Patent Document 1 discloses a technique for preventing an erroneous input caused by a conductor portion of an electronic device itself such as a metal key approaching or contacting a touch panel in a foldable electronic device. In addition, in a capacitive touch panel that detects a change in capacitance, no input is performed even if a conductor other than a conductive material such as a human finger contacts.

JP 2011-154424 A

  In the prior art disclosed in Patent Document 1, erroneous input due to the conductor part of the touch panel device itself such as a metal key approaching or contacting the touch panel can be prevented, but a conductor other than the touch panel device approaches or touches the touch panel by mistake. It is not possible to prevent erroneous input due to For example, when a cable such as a charging cable, a data transmission cable, or a headphone cable approaches or comes into contact with the touch panel, even if the touch panel is a capacitive type, the cable includes a conductor, Occur. When the cable is accidentally placed across the touch panel, or when the touch panel device is placed on the cable with the touch panel facing downward, an erroneous input by the cable occurs.

  In the touch panel device in which an erroneous input has occurred, there is a possibility that a malfunction that is not intended by the user may occur.

Further, in such a state where an erroneous input occurs, the cable often does not move. Therefore, the erroneous input is continuously performed, and the malfunction may occur continuously. In a touch panel device that displays an image using a liquid crystal panel and a backlight, image display is continued as the malfunction continues, and the backlight is lit continuously, so that power is wasted. In addition, in a normal touch panel device, if there is no input for a certain period of time, the backlight is turned off to save power. Even when it does not occur, the power of the touch panel device may be wasted.

Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.
(Embodiment 1)
FIG. 1 is a block diagram showing an internal configuration of a touch panel device according to the present invention, and FIG. 2 is a perspective view showing an external appearance of the touch panel device. The touch panel device is, for example, a smartphone. The touch panel device includes an image display unit 2 and a touch panel 3 for displaying an image. The image display unit 2 is formed in a panel shape, and is, for example, a liquid crystal display or an EL (electroluminescence) display. In the form in which the image display unit 2 is a liquid crystal display, the image display unit 2 includes a liquid crystal panel and a backlight. The side of the surface on which the image displayed by the image display unit 2 can be viewed normally is the front side, and the opposite side is the back side.

  The touch panel 3 has a translucent structure, and is disposed so as to overlap the front surface of the image display unit 2. The user can visually recognize the image displayed on the image display unit 2 through the touch panel 3. As shown in FIG. 2, the touch panel device includes a rectangular parallelepiped casing 6, and the touch panel 3 is disposed in the casing 6 with one surface exposed to the front side. The exposed surface of the touch panel 3 is a detection surface for detecting the approach or contact of a conductor such as a user's finger. The touch panel 3 detects a position where the conductor approaches or contacts a predetermined first distance or less on the detection surface by a capacitance method.

  The image display unit 2 and the touch panel 3 are connected to the control unit 1. The control unit 1 includes a calculation unit that performs a calculation, a memory that stores temporary information associated with the calculation, and a control program necessary for the calculation. The control unit 1 includes a display control unit 12 that causes the image display unit 2 to display an image, and a touch panel control unit 13 that controls the operation of the touch panel 3. The control unit 1 has a function of measuring time.

  In addition, the touch panel device includes an approach / contact sensor 4 that detects approach or contact of a conductor. The proximity / contact sensor 4 is a sensor in the present invention. As shown in FIG. 2, the proximity / contact sensor 4 is mounted on each of both side surfaces along the longitudinal direction in the side surface of the housing 6. The detection surface of the touch panel 3 has a rectangular shape when viewed from the front, and the proximity / contact sensor 4 is arranged in a portion along the long sides of the detection surface in the periphery of the detection surface. The approach / contact sensor 4 is a one-dimensional sensor, and detects a position where the conductor approaches or contacts a predetermined second distance or less in a one-dimensional part on the front side by a capacitance method. The approach / contact sensor 4 detects the approach or contact of the conductor to the front side. For this reason, the position where the conductor has approached or contacted the portions along both long sides of the detection surface of the touch panel 3 is detected. The control unit 1 includes a sensor control unit 14 that controls the operation of the proximity / contact sensor 4. Furthermore, the control unit 1 includes an adjustment unit 11 that adjusts the operations of the display control unit 12, the touch panel control unit 13, and the sensor control unit 14.

  FIG. 3 is a schematic cross-sectional view of the touch panel device. In the drawing, a cross section intersecting with the longitudinal direction of the housing 6 is shown, and the upper side of the drawing corresponds to the front side of the touch panel device. In the drawing, only the touch panel 3, the proximity / contact sensor 4, and the housing 6 are schematically shown, and other components of the touch panel device are omitted. The front surface of the touch panel 3 is a detection surface 31. The proximity / contact sensor 4 is arranged such that a part of the approach / contact sensor 4 protrudes to the front side from the surface obtained by extending the detection surface 31. For this reason, the approach / contact sensor 4 can detect the approach or contact of a conductor farther from the extended surface of the detection surface 31 than the conductor that the touch panel 3 can detect approach or contact. When the conductor approaches the front side of the touch panel device, the approach / contact sensor 4 detects the approach or contact of the conductor before the touch panel 3. Note that the detection sensitivity of the proximity / contact sensor 4 may be higher than that of the touch panel 3, and the proximity / contact sensor 4 may be disposed at a position equivalent to the extended surface of the detection surface 31. For example, the proximity / contact sensor 4 may be configured such that the second distance is longer than the first distance. Even in this form, the approach / contact sensor 4 can detect the approach of the conductor before the touch panel 3. Further, the touch panel device may have a form in which the proximity / contact sensor 4 is disposed in the housing 6.

  Furthermore, the touch panel device includes a communication unit 51 and a communication control unit 52 that perform wireless communication. The communication unit 51 is connected to the communication control unit 52, and the communication control unit 52 is connected to the control unit 1. In addition, the touch panel device includes an operation unit 53, a voice input unit 54, and a voice output unit 55 for a user to operate. For example, the operation unit 53 is a power switch, the audio input unit 54 is a microphone, and the audio output unit 55 is a speaker or a headphone terminal. The touch panel device includes a battery (not shown), and each unit operates with power supplied from the battery. In addition, the form provided with other devices, such as an image pick-up element, may be sufficient as a touch panel apparatus.

  Next, the operation of the touch panel device will be described. The display control unit 12 causes the image display unit 2 to display a specific image such as an application icon. The user visually recognizes an image displayed by the image display unit 2 through the touch panel 3 and inputs a desired part on the detection surface 31 such as a part overlapping the displayed image with a finger to input to the touch panel device. I do. The touch panel 3 receives an input designating a position on the detection surface 31 by detecting a position where the user's finger approaches or contacts on the detection surface 31. The touch panel 3 inputs data indicating the detected position to the touch panel control unit 13. The control unit 1 executes processing according to the input, that is, processing according to the position detected by the touch panel 3. For example, the control unit 1 executes processing for starting an application corresponding to the icon corresponding to the detected position.

  The touch panel device according to the present embodiment prevents the occurrence of an erroneous input due to a cable such as a charging cable accidentally approaching or contacting the touch panel 3. FIG. 4 is a schematic perspective view showing an example in which the cable approaches or contacts the touch panel 3. When the cable 7 crosses over the touch panel 3, a part of the cable 7 approaches or contacts the detection surface 31 of the touch panel 3. Since the cable 7 includes a conductor inside, the touch panel 3 detects the approach or contact of the cable 7. In this case, the cable 7 is also approaching or contacting the approach / contact sensor 4, and the approach or contact of the cable 7 is detected by both the approach / contact sensor 4. When one end of the cable 7 is placed on the detection surface 31 of the touch panel 3, the touch panel 3 detects the contact of the cable 7, and one of the approach / contact sensors 4 detects the approach or contact of the cable 7. Even if a connector is provided at one end of the cable 7 and contact with the detection surface 31 of the connector is not detected, a part of the cable 7 approaches or contacts the detection surface 31 and is detected by the touch panel 3. When the touch panel 3 detects the approach or contact of the cable 7, there is a possibility that an erroneous input unintended by the user may occur. When there is a possibility of erroneous input by such a cable 7, the position where the cable 7 approaches or contacts is detected by both the touch panel 3 and the approach / contact sensor 4. Further, since the cable 7 does not move, the position detected by the touch panel 3 and the approach / contact sensor 4 does not change.

  When the user operates the touch panel device, for example, the user places the touch panel device on a desk and touches the detection surface 31 of the touch panel 3 with a finger. In this case, the touch panel 3 detects the approach or contact of the finger, while the approach / contact sensor 4 does not detect the approach or contact of the conductor. In addition, the user may operate the touch panel device by hand. FIG. 5 is a schematic perspective view illustrating an example in which the touch panel device is operated with one hand. The user touches the detection surface 31 of the touch panel 3 with a finger while holding the touch panel device by hand. In this case, the position where the user's hand approaches or contacts is detected by the touch panel 3 and the proximity / contact sensor 4. The position where the user presses the detection surface 31 with his / her finger and the position where the user's hand approaches or contacts the proximity / contact sensor 4 change every moment. That is, the position detected by the touch panel 3 and the proximity / contact sensor 4 changes every moment. The user may hold the touch panel device with one hand and operate the touch panel device with the finger of the other hand. In this case, detection may be performed by the proximity / contact sensor 4, and the position detected by the proximity / contact sensor 4 may not change for a certain period of time. At the same time, detection is performed on the touch panel 3, and the position detected by the touch panel 3 changes every moment. Therefore, when the position where the conductor approaches or contacts is detected by both the touch panel 3 and the proximity / contact sensor 4 and the detected position does not change, it can be determined that the input is erroneous.

  FIG. 6 is a flowchart illustrating a procedure of processing in which the touch panel device according to Embodiment 1 determines an erroneous input. In parallel with normal operation of the touch panel device such as execution of processing according to input to the touch panel 3 and standby for communication, has the control unit 1 detected the position where the conductor has approached or contacted with the proximity / contact sensor 4? It is determined whether or not (S11). When the approach / contact sensor 4 detects a position where the conductor approaches or contacts, data indicating the detected position is input to the sensor control unit 14, and the control unit 1 receives the data input to the sensor control unit 14. In this case, it is determined that the approach / contact sensor 4 has detected. When there is no detection by the approach / contact sensor 4 (S11: NO), the control unit 1 repeats waiting for detection by the approach / contact sensor 4. When the approach / contact sensor 4 detects the position where the conductor approaches or contacts (S11: YES), the control unit 1 determines whether the touch panel 3 detects the position where the conductor approaches or contacts (S12). ). The control unit 1 determines that detection has been performed on the touch panel 3 when data indicating the detected position is input to the touch panel control unit 13. When there is no detection with the touch panel 3 (S12: NO), the control part 1 returns a process to S11.

  When the position where the conductor approaches or contacts with the touch panel 3 is detected (S12: YES), the control unit 1 does not change the position detected with the approach / contact sensor 4 and the touch panel 3 for a predetermined first time. It is determined whether or not elapses (S13). The value of the first time is stored in the control unit 1 in advance. In S13, the controller 1 measures the elapsed time while the proximity / contact sensor 4 and the touch panel 3 continue to detect the position where the conductor approaches or contacts, and the detected position does not change, and the first time has elapsed. Wait until If the proximity / contact sensor 4 or touch panel 3 no longer detects the position where the conductor has approached or touched before the first time has elapsed, or if the position detected by the proximity / contact sensor 4 or touch panel 3 has changed (S13: NO), the controller 1 returns the process to S11. When the first time has passed without the position detected by the proximity / contact sensor 4 and the touch panel 3 changing (S13: YES), the control unit 1 performs the input specifying the position that the touch panel 3 continues to detect. The acceptance is invalidated (S14). In S <b> 14, the adjustment unit 11 does not perform calculation using data input from the touch panel 3 to the touch panel control unit 13. The adjustment unit 11 disables the control unit 1 from executing processing according to the position where the touch panel 3 continues to detect by invalidating the acceptance of input. While the proximity / contact sensor 4 and the touch panel 3 continue to detect the position where the conductor approaches or contacts, and the detected position does not change, the control unit 1 continues the process of S14 and then ends the process. The control unit 1 repeats the processes of S11 to S14 in parallel with the normal operation of the touch panel device.

  As described above, when the position where the conductor approaches or contacts is detected by both the touch panel 3 and the proximity / contact sensor 4 and the detected position does not change, an erroneous input by the cable 7 as shown in FIG. It is likely that it has occurred. Therefore, when the first time has elapsed without the position detected by the proximity / contact sensor 4 and the touch panel 3 being changed, the touch panel device is further disabled by the cable 7 by disabling the acceptance of the input by the touch panel 3. It is possible to prevent erroneous input.

  In addition, the touch panel device can perform a process corresponding to a combination of a position detected by the touch panel 3 and a duration of time that the conductor approaches or contacts as a process corresponding to the input to the touch panel 3. For example, the touch panel device performs a process of displaying a menu screen on the image display unit 2 or a process of shooting using an imaging element in response to an input of pressing a specific part on the detection surface 31 of the touch panel 3 with a finger for a certain time. Do. The first time used in the process of S13 is longer than the time during which the conductor approaches or contacts the touch panel 3 when executing these processes. For this reason, it is prevented that the user erroneously determines that it is an erroneous input when the user performs an input of pressing a specific portion on the detection surface 31 of the touch panel 3 with a finger for a certain period of time. Is executed.

  Further, the touch panel device performs a process of stopping the image display unit 2 when there is no input to the touch panel 3 for a certain period of time. After the acceptance of the input is invalidated in the process of S14, unless the touch panel 3 detects an approach or contact to another position on the detection surface 31, the state is the same as when there is no input. For this reason, the control part 1 stops the image display part 2 after progress of fixed time. In the form in which the image display unit 2 is a liquid crystal display, the control unit 1 turns off the backlight by stopping the image display unit 2. In the form in which the image display unit 2 is an EL display, the control unit 1 stops the light emission of the image display unit 2 by stopping the image display unit 2.

  Further, since the proximity / contact sensor 4 can detect the approach or contact of the conductor prior to the touch panel 3, the touch panel device detects the approach of the cable 7 that causes an erroneous input at an early stage. 7 can be reliably determined. Further, by detecting the approach of the cable 7 at an early stage, the time required to determine an erroneous input can be shortened, and the touch panel device can reduce the occurrence of an erroneous input as much as possible. Further, when the cable 7 approaches or contacts the touch panel 3, the cable 7 often approaches or contacts the long side of the detection surface 31, and the cable 7 approaches either of the long sides of the detection surface 31. Without approaching or touching the short side without probability, there is less probability. Therefore, by providing the proximity / contact sensor 4 along both long sides of the detection surface 31, the touch panel device detects the cable 7 that has approached or contacted the long side of the detection surface 31 and is surely erroneous input. Occurrence can be determined.

  As described above in detail, in the present embodiment, the touch panel device detects the position where the conductor approaches or comes into contact with both the touch panel 3 and the proximity / contact sensor 4, and the detected position does not change. Processing according to the input to the touch panel 3 is prohibited. Thereby, the touch panel device prevents the occurrence of erroneous input due to the cable 7 approaching or touching the touch panel 3. By preventing the occurrence of an erroneous input, the touch panel device can prevent a malfunction that is not intended by the user, and can prevent waste of power due to the occurrence of the malfunction. In addition, the touch panel device can automatically stop the image display unit 2 even when the cable 7 is approaching or in contact with the touch panel 3. Therefore, the touch panel device can realize power saving.

(Embodiment 2)
The configuration of the touch panel device according to the second embodiment is the same as that of the first embodiment. FIG. 7 is a flowchart illustrating a procedure of processing in which the touch panel device according to Embodiment 2 determines an erroneous input. In parallel with the normal operation of the touch panel device, the control unit 1 determines whether or not the proximity / contact sensor 4 detects a position where the conductor approaches or contacts (S21). When there is no detection by the approach / contact sensor 4 (S21: NO), the control unit 1 repeats waiting for detection by the approach / contact sensor 4. When the approach / contact sensor 4 detects the position where the conductor approaches or contacts (S21: YES), the control unit 1 determines whether the touch panel 3 detects the position where the conductor approaches or contacts (S22). ). When there is no detection with the touch panel 3 (S22: NO), the control part 1 returns a process to S21.

  When the position where the conductor approaches or contacts with the touch panel 3 is detected (S22: YES), the control unit 1 does not change the position detected with the approach / contact sensor 4 and the touch panel 3 for a predetermined second time. It is determined whether or not elapses (S23). The value of the second time is stored in the control unit 1 in advance. If the proximity / contact sensor 4 or touch panel 3 no longer detects the position where the conductor has approached or touched before the second time has elapsed, or if the position detected by the proximity / contact sensor 4 or touch panel 3 has changed (S23: NO), the control unit 1 returns the process to S21. When the second time has passed without the positions detected by the proximity / contact sensor 4 and the touch panel 3 changing (S23: YES), the control unit 1 shifts the touch panel device to the sleep state (S24) and performs the process. finish. In S <b> 24, the control unit 1 stops the image display unit 2, the touch panel 3, and the approach / contact sensor 4. Accordingly, the backlight is turned off when the image display unit 2 is a liquid crystal display, and the light emission of the image display unit 2 ends when the image display unit 2 is an EL display. Further, processing according to the position detected by the touch panel 3 is prohibited. Further, the control unit 1 stops the voice input unit 54 and the voice output unit 55. The adjustment unit 11 stops the display control unit 12, the touch panel control unit 13, and the sensor control unit 14, and the control unit 1 stops most functions. For example, the control unit 1 stops functions other than the function of starting the touch panel device in response to a signal from the operation unit 53. When the user operates the operation unit 53, the operation unit 53 inputs a signal instructing activation to the control unit 1, and the control unit 1 activates the touch panel device from the sleep state according to the input signal. After startup, the control unit 1, the image display unit 2, the touch panel 3, the proximity / contact sensor 4, the voice input unit 54, and the voice output unit 55 perform normal operations. The control unit 1 repeats the processes of S21 to S24 in parallel with the normal operation of the touch panel device.

  By the processes of S21 to S24, the touch panel device determines an erroneous input when the second time has passed without the positions detected by the proximity / contact sensor 4 and the touch panel 3 changing as in the first embodiment. Furthermore, the touch panel device can prevent further erroneous input by the cable 7 by shifting to the sleep state. Further, when the touch panel device shifts to the sleep state, the image display unit 2 that consumes a large amount of power is stopped, and power consumption is reduced. Since the touch panel device is highly likely not to be used for a long time in a state where erroneous input by the cable 7 occurs, power consumption can be suppressed by shifting to the sleep state.

  Similarly to the first embodiment, the touch panel device can perform processing according to the combination of the position detected by the touch panel 3 and the duration for which the conductor approaches or contacts. The second time used in the process of S23 is longer than the time during which the conductor approaches or contacts the touch panel 3 when performing these processes. For this reason, when the user performs an input for holding a specific portion on the detection surface 31 of the touch panel 3 with a finger for a certain period of time, the sleep state is prevented and deterioration of the operability of the touch panel device is prevented. Is done.

  As described above in detail, in the present embodiment, the touch panel device detects the position where the conductor approaches or comes into contact with both the touch panel 3 and the proximity / contact sensor 4, and the detected position does not change. Enter sleep mode. Thereby, the touch panel device prevents occurrence of erroneous input due to the cable 7 approaching or contacting the touch panel 3, and prevents malfunction that is not intended by the user. Further, by stopping the image display unit 2 by shifting to the sleep state, it is possible to reliably reduce power consumption and achieve power saving.

  In the present embodiment, when an erroneous input is determined, the mode immediately shifts to the sleep state is shown. However, the touch panel device performs processing for invalidating the input to the touch panel 3 and then the sleep state. It may be in the form of shifting to. In this form, the touch panel device sets the second time to be longer than the first time, performs the same process as in the first embodiment, and performs the process of invalidating the input to the touch panel 3 in S14. Next, when the second time has elapsed, a process for shifting to the sleep state is performed. Also in this form, it is possible to prevent erroneous input and realize power saving. In addition, the touch panel device is not limited to the mode of shifting to the sleep state when an erroneous input is determined, and when the erroneous input is determined, the process for invalidating the input to the touch panel 3 and the image display unit 2 are stopped. The form which performs a process may be sufficient. Also in this embodiment, it is possible to realize power saving by preventing erroneous input and stopping the image display unit 2.

  In the first and second embodiments described above, the approach / contact sensor 4 is disposed along both long sides of the detection surface 31 of the touch panel 3. However, the position where the approach / contact sensor 4 is disposed is as follows. It is not limited to this. The proximity / contact sensor 4 may be disposed in any part of the outer periphery of the housing 6 included around the detection surface 31. For example, the proximity / contact sensor 4 may be disposed on the entire outer periphery of the housing 6 around the detection surface 31, or may be disposed along the short side of the detection surface 31. The shape of the detection surface 31 may be a shape other than a rectangle. In Embodiments 1 and 2, the touch panel device is a smartphone. However, the touch panel device may be another information processing device such as a tablet. Further, the touch panel device may be configured to input / output data with other devices such as a controller of a game machine or an input device of a computer.

  As described above, the touch panel device according to the present invention includes the touch panel 3 that detects the position on the detection surface 31 where the conductor approaches or contacts the predetermined first distance or less, and corresponds to the position detected by the touch panel 3. In the touch panel device that executes processing, a sensor 4 that detects a position where the conductor approaches or contacts a predetermined second distance or less is provided on at least a part of the periphery of the detection surface 31 of the touch panel 3. Alternatively, when the touch panel 3 and the sensor 4 detect the touched position, and the positions detected by the touch panel 3 and the sensor 4 do not change for a predetermined first time or longer, the touch panel 3 and the sensor 4 correspond to the position detected by the touch panel 3. And a means for prohibiting the processing.

  In the present invention, the touch panel device is provided with a sensor 4 that detects a position where the conductor approaches or contacts at least a part of the periphery of the detection surface 31 of the touch panel 3. The touch panel device corresponds to the position detected by the touch panel 3 when the position where the conductor approaches or contacts is detected by both the touch panel 3 and the sensor 4 and the detected position does not change for a predetermined first time. Do not process. Thereby, the touch panel device prevents occurrence of erroneous input due to the cable approaching or touching the touch panel 3.

  In the touch panel device according to the present invention, the touch panel 3 and the sensor 4 detect an image display unit 2 that displays an image superimposed on the touch panel 3, and a position where a conductor approaches or contacts, and the touch panel 3 and the sensor 4. And a means for stopping the image display unit 2 when the detected position does not change for a predetermined second time.

  In the present invention, the touch panel device stops the image display unit 2 when the position where the conductor approaches or contacts is detected by both the touch panel 3 and the sensor 4 and the detected position does not change for a predetermined second time. To do. Since there is a high possibility that the touch panel device will not be used for a long time in a state where an erroneous input by a cable occurs, power consumption can be suppressed by stopping the image display unit 2.

  In the touch panel device according to the present invention, the sensor 4 has a distance from a detection surface 31 of the touch panel 3 of a conductor that can detect approach or contact from the detection surface 31 of a conductor that the touch panel 3 can detect approach or contact. It is characterized by being configured to be longer than this distance.

  In the present invention, the sensor 4 can detect the approach or contact of a farther conductor as compared to the touch panel 3.
