  FIG. 10 is a block diagram showing only the characteristic part of the display device for explaining the present invention. In the following, the present invention will be described based on a vehicle-mounted display device. However, the present invention is not limited to a vehicle-mounted device, and can be applied to, for example, a home display device. . In FIG. 10, the same components as those in FIG. 10, in addition to the configuration of FIG. 6, the audio adjustment circuit 210 is configured to be able to output audio from the first speakers 16-1 to 416-4 disposed at various locations on the vehicle 198, The unit 200 is configured to be able to detect the sound volume from the first detection sensor 320 to the fifth detection sensor 330 disposed on the headrest portion of each seat of the vehicle 198 via the voice detection unit 224. Have been added.

  FIG. 11 shows an arrangement example of speakers and detection sensors. As shown in FIG. 11, the first speaker 16-1 in the vehicle 19 is on the driver seat side door, the second speaker 16-2 is on the passenger seat side door, and the third speaker 16-3 is on the right side of the rear seat 18. The fourth speaker 16-4 is arranged on the left side of the rear seat 18. Further, the first detection sensor 320 is disposed in the headrest 23 of the driver seat 13, the second detection sensor 322 is disposed in the headrest 24 of the passenger seat 12, and the third detection sensor 324 is disposed in the headrest 25 of the rear seat 18. The fourth detection sensor 326 is disposed in the headrest 26 of the rear seat 18, and the fifth detection sensor 328 is disposed in the headrest 27 of the rear seat 18. The arrangement example of the speaker and the detection sensor is merely an example, and various other modes can be taken according to the internal shape of the vehicle, the arrangement of the seats, and the like.

  FIG. 12 is a schematic diagram showing a cross-sectional shape of the display unit 7. The touch panel 124 includes a pair of flexible transparent insulating substrates 130 and 138, transparent electrodes 132 and 136 respectively formed on the transparent insulating substrate, and dot spacers 134 arranged in a matrix on the transparent electrode 132. When the dot spacer 134 comes into contact with the transparent electrode 136 when the user presses on the transparent electrode substrate 130, the position of the contact is detected by measuring the electric resistance, and the control unit 200 reads the input information. It is configured. Note that the touch panel 124 is not limited to the above configuration, and other types of touch panels can be employed.

  The liquid crystal panel 100 is divided into a plurality of strips in the vertical direction, and left side (passenger seat side) display pixels 109 and right side (driver seat side) display pixels 110 are alternately formed. All the left (passenger side) display pixels 109 are driven and controlled by the first image adjustment circuit 208, and all the right (driver's seat side) display pixels 110 are driven and controlled by the second image adjustment circuit 209. .

  On the surface side of the liquid crystal panel 100, a parallax barrier 108 'formed of polycarbonate or the like is disposed. Light shielding bands 142 and 144 are alternately formed on the front and back of the parallax barrier 108 '. In the example of FIG. 12, the parallax barrier 108 ′ in which the light shielding bands 142 and 144 are alternately formed is used. However, as shown in FIG. 3, it is possible to use the parallax barrier 108 as a matter of course.

  The observer 11 in the first visual field region including the driver's seat 13 visually recognizes only the image as the aggregate of the right side (driver's seat side) display pixels 110 as the driver's seat image by the action of the parallax barrier 108 '. be able to. On the other hand, the observer 10 in the second visual field area including the front passenger seat 12 uses only the image as the aggregate of the left side (passenger side) display pixels 109 as the front passenger seat image by the action of the parallax barrier 108 '. It can be visually recognized. In this way, in practice, every other image obtained by dividing one screen into a plurality of parts in the vertical direction is visually recognized, but by making the width of one belt-like portion very narrow, the passenger seat can also be viewed from the driver's seat side. It is possible to visually recognize separate images from the side.

  FIG. 13 shows a display image example, and FIG. 14 shows a visual field range and an audio output range. FIG. 13A shows a second display image (moving image or the like) that can be viewed in the first visual field range (see 601 in FIG. 14) including the driver's seat 13 and is driven and controlled by the first image adjustment circuit 208. In this example, a display image for navigation is shown. FIG. 13B is an example of a first display image that can be viewed in the second visual field range (see 602 in FIG. 14) including the passenger seat 12 and is controlled by the second image adjustment circuit 209. An example of a display image on the CD operation screen is shown. As shown in FIG. 14, the observer of the seat using the headrest 25 in the driver's seat 13 and the rear seat 18 exists in the first visual field range, so that the second display image can be viewed, and the passenger seat 12 and the rear seat. Since the observer of the seat using the headrest 27 at 18 is in the second visual field range, the first display image can be viewed. However, since the observer of the seat using the headrest 26 in the rear seat 18 is present in the crosstalk area (see 603 in FIG. 14), it is in a situation where any display image can be seen to some extent.

  In the example of FIG. 14, the second sound (navigation sound) corresponding to the second display image is output from the first speaker 16-1 and the third speaker 16-3, and is output from the driver seat 13 and the rear seat 18. A sound that can be satisfactorily provided to the observer of the seat using the headrest 25 is output. Furthermore, in the example of FIG. 14, the first sound (music CD playback sound) corresponding to the first display image is output from the second speaker 16-2 and the fourth speaker 16-4, and the passenger seat 12 and the rear seat 18 are output. Thus, a sound that can be satisfactorily viewed by an observer of the seat using the headrest 27 is output. In addition, it is set so that both the first sound and the second sound can be viewed by the observer of the seat using the headrest 26 in the rear seat 18 existing in the crosstalk area 603.

  In FIGS. 13 and 14, the driver's seat side is the navigation display image and sound, and the passenger seat side is the CD playback display image and sound. However, any source (CD / DVD playback unit 201, CD) connected to the display device is used. An image, a display image and / or a sound from the radio reception unit 202, the TV reception unit 203, and the navigation unit 206) can be distributed to the driver seat side (first visual field region) and the passenger seat side (second visual field region). it can.

  It is also possible to distribute the display image or the like of a TV broadcast channel to the driver seat side and the passenger seat side. This can be achieved by using a TV display image recorded by the HD playback unit 205 in the past using the HD playback unit 205 when a TV receiver having a plurality of tuners exists as a source. .

  In addition, the display image recorded on the same recording medium, for example, the first DVD, and the display image recorded on the second DVD can be distributed to the driver seat side and the passenger seat side. This can be achieved, for example, when a deck capable of simultaneously reproducing a plurality of recording media exists as a source, or when a DVD display image reproduced in the past using the HD reproducing unit 205 is recorded by the HD reproducing unit 205. .

  In addition, different display images recorded on the same DVD (for example, when display images are recorded at multiple angles) can be distributed to the driver seat side and the passenger seat side. This is because when there is a deck having a plurality of optical pickup units as a source, when there is a deck that can output two display images from the same DVD while reproducing and buffering a DVD at high speed, This can be achieved, for example, when a DVD display image reproduced in the past using the reproducing unit 205 is recorded by the HD reproducing unit 205.

  FIG. 15 shows an example in which the visual field range and audio output range shown in FIG. 14 are changed. In the example of FIG. 15, the first visual field range 701 of the display unit 7 is changed so that the second display image can be satisfactorily provided to an observer who uses the headrests 25 and 26 at the driver's seat 13 and the rear seat 18. did. Further, in the example of FIG. 15, the first display image can be satisfactorily provided to an observer who uses the headrest 27 in the passenger seat 12 and the rear seat 18 within the second visual field range 702 of the display unit 7. Therefore, the observer of the seat using the headrest 26 with the rear seat 18 existing in the crosstalk area 603 in FIG. 14 can also see the second display image satisfactorily. For example, the parallax barrier 108 ′ may be moved by a driving device such as a motor, and the display direction (range) may be changed by changing the positions of the light shielding bands 132 and 134 as the parallax barrier 108 ′ moves. it can.

  Further, in the example of FIG. 15, the audio adjustment circuit 210 outputs the audio output of the first speaker 16-1 to the fourth speaker 16-4 based on the audio data from the first detection sensor 320 to the fifth detection sensor 328. Control was performed so that the first sound corresponding to the second display image is localized in the first region 710 where the observer using the headrests 25 and 26 exists in the driver's seat 13 and the rear seat 18. Similarly, the audio adjustment circuit 210 controls the audio output of the first speaker 16-1 to the fourth speaker 16-4 based on the audio data from the first detection sensor 320 to the fifth detection sensor 328, Control was performed so that the second sound corresponding to the first display image is localized in the second region 720 where the observer using the headrest 27 in the passenger seat 12 and the rear seat 18 exists. Therefore, the observer of the seat who uses the headrest 26 with the rear seat 18 existing in the crosstalk region 603 in FIG. 14 can also hear the first sound satisfactorily.

  For the control for sound localization, for example, the sound adjustment circuit 210 detects sound data from the fourth detection sensor 326 that is likely to have the head of an observer who uses the headrest 26 in the rear seat 18, Generate a cancellation signal based on the detected audio data and cancel the data corresponding to the second audio in the audio data as noise, or adjust the volume and delay time from each speaker, The sound output of the first speaker 16-1 to the fourth speaker 16-4 may be controlled.

  FIG. 16 shows another example in which the visual field range and the audio output range shown in FIG. 14 are changed. In the example of FIG. 16, the second visual field range 802 of the display unit 7 is changed so that the first display image can be satisfactorily provided to an observer who uses the headrests 27 and 26 in the passenger seat 12 and the rear seat 18. did. Further, in the example of FIG. 16, the second display image can be satisfactorily provided to an observer who uses the headrest 25 in the driver's seat 13 and the rear seat 18 within the first visual field range 801 of the display unit 7. Accordingly, an observer of the seat using the headrest 26 with the rear seat 18 existing in the crosstalk area 603 in FIG. 14 can also see the first display image satisfactorily.

  Further, in the example of FIG. 16, the audio adjustment circuit 210 outputs the audio output of the first speaker 16-1 to the fourth speaker 16-4 based on the audio data from the first detection sensor 320 to the fifth detection sensor 328. Control was performed so that the first sound corresponding to the second display image is localized in the first region 810 where the observer using the headrest 25 in the driver's seat 13 and the rear seat 18 exists. Similarly, the audio adjustment circuit 210 controls the audio output of the first speaker 16-1 to the fourth speaker 16-4 based on the audio data from the first detection sensor 320 to the fifth detection sensor 328, Control was performed so that the second sound corresponding to the first display image was localized in the second region 820 in which the observer using the headrests 26 and 9 exists in the passenger seat 12 and the rear seat 18. Therefore, the observer of the seat using the headrest 26 with the rear seat 18 existing in the crosstalk area 603 in FIG. 14 can also hear the second sound satisfactorily.

  For the control for sound localization, for example, the sound adjustment circuit 210 detects sound data from the fourth detection sensor 326 that is likely to have the head of an observer who uses the headrest 26 in the rear seat 18, A cancellation signal is generated based on the detected sound data and the data corresponding to the first sound in the sound data is canceled as noise, or the first sound volume and delay time are adjusted based on the first sound. The sound output of the speakers 16-1 to 16-4 may be controlled.

  The three cases where the display image and the sound are provided in the vehicle 19 have been described with reference to FIGS. Therefore, a predetermined selection switch is provided in the operation unit 15 so that the user can select, and according to the user's selection, the display image and the sound are output so as to be in any of the situations of FIGS. Can be configured to change.

  Further, in FIGS. 14 to 16 described above, the display image and the sound are controlled together, but a predetermined selection switch is provided in the operation unit 15 to display only the display image or only the sound. It is also possible to configure so as to be any one of the three situations shown in FIG.

  Furthermore, the operation unit 15 is provided with a selection switch for setting the visual field range of the display unit 7 to any of the states shown in FIGS. 14 to 16, for example, according to the visual field information corresponding to the visual field range selected by the user. The audio adjustment circuit 210 can also be configured to control so that the range in which audio is provided is any one of FIGS. That is, when the user selects the visual field range shown in FIG. 14, the audio adjustment circuit 210 controls the first speaker 16-1 to the fourth speaker 16-4 so that the audio output as shown in FIG. 14 is obtained. It will be.

  In other words, the display image and / or sound selected by the user can be supplied to the crosstalk area by the visual field adjustment and sound control circuit 210 of the display unit 7.

  In the example of FIGS. 14 to 16 described above, the noise canceling method described above is used to localize the voice selected by the user in the crosstalk area. However, the following bone conduction speaker or directional speaker is used. The same control can be performed.

  FIG. 17 shows an arrangement example of bone conduction speakers. In the example of FIG. 17, the bone conduction speaker 901 is embedded at a position where it can come into contact with a portion above the neck of the observer 900 using the headrest 26 of the rear seat 18. Unlike the seat cushion, the headrest 26 has low adhesion stability with the body of the observer 900, but the skull or cervical vertebra closest to the vocal cord can detect the bone conduction sound. If the head is pressed against the headrest 26, a clear signal can be taken out. Note that the position and number of bone conduction speakers 901 are not particularly limited, and various combinations can be employed.

  Therefore, for an observer who uses the headrest 26 of the rear seat 18 existing in the crosstalk region 603, the bone conduction speaker 901 embedded in the headrest 26, and the first speaker 16-for the observer at the driver's seat 13. 1 to the observer of the passenger seat 12 from the second speaker 16-2, to the observer using the headrest 25 of the rear seat 18 from the third speaker 16-3 and the headrest 27 of the rear seat 18. For the observer to be used, if the fourth speaker 16-4 is configured to output sound, and each speaker is properly used for the first sound and the second sound, the observer of the designated seat is used. It is possible to supply the audio specified in

  FIG. 18 shows a configuration example of a directional speaker. In FIG. 18, a gear 1002 is fixed to a rotating shaft 1001 of a motor whose operation is controlled by a sound adjustment circuit 210. The gear 1002 is engaged with a gear 1004 fixed to the directional speaker 1000, and the gear 1004 is supported by the shaft 1003 so as to be rotatable about the shaft 1003. Therefore, the direction of the directional speaker 1000 can be adjusted by the motor control by the sound adjustment circuit 210 (the control amount for the motor is stored and the control amount is selected according to the reproduction state), and the directivity (direction) ) Can be controlled. Note that it is also possible to adopt a configuration in which the directivity of the speaker is adjusted manually by a configuration similar to the configuration shown in FIG.

  FIG. 19 shows an example of changing the audio output by the directional speaker shown in FIG. In FIG. 19, a first directivity speaker 1100 as shown in FIG. 18 is arranged instead of the third speaker 16-3 in FIG. 14, and a second directivity as shown in FIG. 18 is used instead of the fourth speaker 16-4. This is an example in which a characteristic speaker 1101 is arranged. In FIG. 19A, the first directional speaker 1100 is rotated to a position that covers only the headrest 25 of the rear seat 18 by the motor control according to the instruction from the audio adjustment circuit 210, and the second directional speaker 1101 is moved to the position of the rear seat 18. The headrests 26 and 27 were rotated to cover them. Further, in FIG. 19B, the first directional speaker 1100 is rotated to a position that covers the headrests 25 and 26 of the rear seat 18 by motor control according to an instruction from the audio adjustment circuit 210, and the second directional speaker 1101 is moved. The rear seat 18 was rotated to a position that only covers the headrest 27. As described above, even when the directional speaker is used, the sound selected by the user can be localized in the crosstalk area.

  In the above-described embodiment, a bone conduction speaker or a directional speaker is used to localize the voice selected by the user in the crosstalk area. However, headphones or earphones can be used instead. In that case, a jack or connector for headphones or earphones may be provided for an observer present in the crosstalk area.

  In addition to the crosstalk area, in order to provide safer and more reliable specific sound, in addition to the speakers and detection sensors described above, headphones and earphone jacks for observers in other seats A connector can also be provided. For example, for the passenger seat, the second sound can be output from headphones or earphones, and the first sound can be set to be output from all speakers.

  In the above-described embodiment, the description has been given of supplying or localizing the display image or sound selected to each seat by the user's selection or the like. However, in an emergency, it is preferable to perform voice control so as to cancel or change the above setting. For example, as shown in FIGS. 13 and 6, navigation is performed when the driver's seat side (first visual field range) is set to a display image and voice for navigation and the passenger seat side (second visual field range) is set to a display image and voice for CD playback. When the VICS information is received from the unit 206, or when emergency information such as an earthquake or disaster is received, the voice adjustment circuit 210 outputs the emergency information from all the speakers 310 to 316, so that the first speaker 16- The first to fourth speakers 16-4 are controlled. In this case, the audio adjustment circuit 210 can determine the audio content from the audio signal supplied from the navigation unit 206, and can control the emergency information to be output from all the speakers based on the determination result. Further, when the navigation unit 206 receives predetermined emergency information, the navigation unit 206 transmits a specific signal to the control unit 200 and the voice adjustment circuit 210, and the control unit 200 and the voice adjustment circuit 210 receive the specific signal. Alternatively, control may be performed so that all voices and display images are voices and display images from the navigation unit 206.
