  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 operator 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 left side (passenger side) display pixels 109 are driven and controlled by the first image adjustment circuit 208, and all right side (driver 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. Of course, it is possible to use the parallax barrier 108 as shown in FIG. 3.

  The right occupant 400 can visually recognize only the image as an aggregate of the right (driver's seat side) display pixels 110 as the driver's seat display image by the action of the parallax barrier 108 '. On the other hand, the passenger 401 on the left side can visually recognize only the image as an aggregate of the left (passenger side) display pixels 109 by the action of the parallax barrier 108 ′. Thus, 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 strip portion very narrow, it is separately provided from the right side and the left side. Can be visually recognized.

  FIG. 13 shows an example of an operation flow at the time of registration for customizing the operation button arrangement using the display device described above. The following operation flow is mainly executed by the control unit 200 according to a program stored in advance.

  When the power of the display device 20 is turned on and various functions are operable, a program is started by inputting a customization instruction from the operation unit 15 or the remote controller 217 (S1).

  Next, when an operation for customization is selected, an image for customization is displayed on the display unit 7 (S2). FIG. 14 shows an example of the customization image displayed on the screen. The operator selects one registration button, for example 401, among the settings 1 to 3 on the customization image displayed on the screen shown in FIG.

  Next, in order to customize the button arrangement in the passenger seat (P seat) or the driver seat (D seat), the seat to be customized is set (S3). An example of an image display for setting a seat is shown in FIG. When, for example, the registration button 401 is selected on the image displayed on the screen shown in FIG. 14, the selection image shown in FIG. 15 is automatically displayed on the screen. Or the passenger seat 405 is selected. If a seating sensor or the like is arranged on each seat and it is possible to determine in advance which seat operator is operating, this step can be omitted.

  Next, the person corresponding to the customization is set (S4). An example of an image display for setting a person is shown in FIG. When a seat is selected on the image displayed on the screen shown in FIG. 15, the image shown in FIG. 16 is automatically displayed on the screen, so that the operator can identify the operator name (for example, "Father" or the like) is input to the predetermined field 406 using the operation unit 15, the remote controller 217, the soft keyboard, or the like. Note that this step can be omitted when customization is performed without characterizing the operator (for example, when setting common to the display device).

  The fingerprint data can be registered using the fingerprint sensor 332 simultaneously with the registration of the operator name. The registered fingerprint data is stored in the memory 218 together with the operator name. It should be noted that such processing is not necessary when customization is performed without characterizing the operator (for example, when setting common to the display device).

  Next, a target source to be registered is set (S5). When a person is set on the image displayed on the screen shown in FIG. 16, the image shown in FIG. 17 is automatically displayed on the screen, so the operator selects, for example, a button 413 for selecting navigation. And set the source for customization. Note that this step can be omitted when customization is performed without specifying a source (for example, when common settings are made for all sources). Further, the currently selected source may be automatically set as the target source, and in this case, the setting at this step by the operator is unnecessary.

  Next, the operation button of the set source on the set seat side is customized (S6). In the customization of the operation buttons, the operator can freely set the size, shape, brightness, color, position on the screen, and function of the operation buttons. In the present embodiment, the operator can freely arrange the operation buttons anywhere in the display area of the display unit 7 by using the operation unit 15, the remote controller 217, or the like. It goes without saying that various other methods can be adopted as the setting operation method.

  Next, it is determined whether or not the customization of the operation button set by the operator falls under the prohibited items (S7).

  The prohibition includes a case where the operation button arrangement to be registered this time overlaps with the already registered operation button arrangement for the opposite seat. In the present embodiment, even though one screen of the display unit 7 can be divided into multiple parts so that a plurality of operators can view different images, there is only one touch panel 124. For example, FIG. As described above, if the operation buttons are arranged close to each other on the display unit 7 and the operation areas overlap, the control unit 200 cannot determine which seat the operation input is. is there. As shown in FIG. 21, the region 701 of the display unit 7 is actually composed of the left display pixel 109 and the right display pixel 110 (see FIG. 4). Accordingly, some operation buttons 708 of the first display pixel 8 are displayed by the left display pixel 109, and some operation buttons 709 of the second display pixel 9 are displayed by the right display pixel 110. That is, the operation button 708 and the operation button 709 are strictly arranged close to each other on the display unit 7. In this way, the operation button arrangement for a plurality of operators that are arranged close to each other on the display unit and the operation areas overlap is referred to as “overlap”.

  FIG. 18 shows an example in which the operation button arrangement on the driver's seat side overlaps with the operation button arrangement on the passenger seat side. FIG. 18A shows an operation button arrangement example 414 for CD operation already registered on the passenger seat side, and FIG. 18B shows an operation button arrangement to be registered for navigation on the driver seat side this time. Example 415 is shown. If the navigation operation button arrangement example 415 is registered at this time, the control unit 200 displays a navigation image (including operation buttons) for the driver's seat on the display unit 7 and is directed to the passenger seat side. When the CD operation image is displayed, the operation buttons overlap in position on the driver's seat side and the passenger seat side, and the control unit 200 determines which seat the input using the touch panel 124 is for. Will not be able to judge.

  Therefore, in this embodiment, the operation button arrangement to be registered this time is compared with all operation button arrangements of the opposite seats already registered, and if there is any overlap in position, it is prohibited. Judged to be applicable to the matter. In other words, even when registering on the driver's seat side, the duplication with all operation button arrays already registered on the passenger seat side is confirmed, and registration is permitted only when there is no complete duplication. .

  However, as a method for prohibiting duplication of the operation button arrangement, various methods can be considered as follows.

  (1) Prioritizing registration on the driver's seat side, there is no prohibition on registration on the driver's seat side, and only when registering on the passenger seat side, A method of judging duplication.

  (2) Also, there is no prohibition for registration on any seat side, and duplication is determined when used (see the flow of FIG. 20).

  (3) An area where operation buttons can be arranged in each seat is set in advance (for example, on the driver's seat side, the right half on the driver's seat side in the image area of the display unit 7). A method that prevents placement.

  (4) A method in which several patterns that do not overlap each other are prepared in advance on the driver's seat side and the passenger's seat side, and the operator can select from them.

  (5) A method of invalidating only the overlapping portions on the driver's seat side and the passenger seat side.

  In the case of (3) and (4) above, there is no possibility that the operation button arrangement is potentially duplicated between the driver's seat side and the passenger's seat side, so the determination of S7 in the flow shown in FIG. It becomes unnecessary.

  If it is determined in S7 that the item is prohibited, the operator is notified that the item is prohibited (S8) using the display unit 7 (S8). Encourage resetting. The operator who has received the notification may ignore the notification and register the operation buttons while overlapping each other. In that case, the arrangements already registered may be automatically moved so that they do not overlap each other.

  If the prohibited items are not satisfied in S7, the operation button array data set up to now is stored and registered in the memory 218 (S9), and the series of operations is completed (S10). FIG. 19A shows an example 416 of the driver seat side, the operator name “father”, and the operation button arrangement for navigation operation set as described above. For example, this operation button arrangement 416 is set so as not to overlap with the already registered button arrangement 417 for CD operation on the passenger seat side shown in FIG. 19B.

  According to the above-described flow, it is possible to customize and register operation button arrangements regarding a specific seat, a specific person, and a specific source. Note that the step of setting a seat (S3), the step of setting a person (S4), and the step of setting a source (S5) do not have to be in the order shown in FIG. Also good.

  In the step of setting a seat (S3), the step of setting a person (S4), and the step of setting a source (S5), the frequency of use is counted in the memory 218 and the initial display of each setting screen. As described above, the most frequently used items may be displayed characteristically or arranged in order of frequency.

  In the step of setting a seat (S3), the step of setting a person (S4), and the step of setting a source (S5), the last state when the display device 20 is turned off is stored in the memory 218 or the like. The setting at that time may be displayed as an initial display of each setting image.

  Furthermore, in the flow of FIG. 13, the display unit 7 has been described in accordance with an example in which different display images are displayed in two directions. However, when different display images are displayed in three or more directions. It is also possible to cope with the problem based on the flow shown in FIG. 13 by increasing the setting of S3.

  FIG. 20 shows an example of an operation flow during operation for using the customized operation button arrangement. The following operation flow is mainly executed by the control unit 200 according to a program stored in advance.

  When the power of the display device 20 is turned on and various functions are operable, a single display (when only one display image is displayed on the display unit) to a plurality of displays (individual displays for a plurality of viewing directions) The program is started when a predetermined instruction is input from the operation unit 15 or the remote controller 217 to the case of displaying an image on the same screen (S11).

  Next, the person corresponding to the registered customization information is set (S12). The selection of the person setting is performed by an appropriate selection image displayed on the display unit 7. Instead of displaying and selecting the selected image, it is possible to substitute the person setting using the fingerprint sensor 332. For example, when fingerprint data is input from the fingerprint sensor 332, the fingerprint collation unit 330 collates with the fingerprint data stored in the memory 218 to identify the person who entered the fingerprint. Note that this step is not necessary when customization is not performed in correspondence with a person.

  Next, the side of the passenger seat (P seat) or the driver's seat (D seat) from which the customized information is read is selected by the seat (S13), and the target source is set (S14). It should be noted that S13 is not necessary when customization is not performed corresponding to the seat, and S14 is unnecessary when customization is not performed corresponding to the seat at the source.

  Next, operation button arrangement data customized for a specific seat, a specific person, and a specific source is read (S15).

  Next, it is determined whether or not the read operation button arrangement corresponds to a prohibited matter (S16).

  The prohibited item corresponds to the case where the operation button arrangement to be used this time overlaps with the operation button arrangement for the opposite seat that is already being used. Even if different images can be displayed for a plurality of operators on the display unit 7, the touch panel 124 is one, so if the operation buttons are arranged in an overlapping manner, the operation input for which seat is used. This is because it cannot be determined by the control unit 200 side.

  If it is determined in S16 that it is a prohibited matter, the operator is notified that the prohibited matter is applicable using the display unit 7 (S17), and the operation for the opposite seat that has already been used is performed. The standard operation button layout that does not overlap with the button layout is read and set to be usable (S18). If it is determined in S16 that the prohibited item is applicable, the standard operation button arrangement may not be read, but the operator may be prompted to select again an operation button arrangement that does not correspond to the prohibited item.

  If the prohibited items are not satisfied in S16, the operation button arrangement read in S15 is set so that it can be used by the operator, and the series of operations is completed (S19).

  In this way, the customized operation button arrangement is read out and set so that it can be used by the operator without overlapping between the driver's seat side and the passenger seat side. Note that in the case of customization registration (see the flow of FIG. 13), if the registration is permitted only when the operation button arrangements do not overlap, the flow of S16 is not necessary.

  In the above embodiment, different images are provided for the driver seat and the passenger seat, and different operation button arrangements are provided, but three or more seats (for example, the front 3 Similarly, it is also possible to provide different images and provide different operation button arrangements for the case of corresponding to a vehicle in a seat or including a rear seat.

  As another example of the above-described embodiment, when an occupant gets on the vehicle 19, the occupant is specified by various detection means (for example, image recognition) or the seating position is detected (image recognition, seating answer, etc.) The person and the seat direction may be specified (set). In such a case, the button arrangement in the specified person and the seat direction may be automatically registered / read out with respect to the source selected by the operator via the operation unit 15 (automatic rather than menu setting). Setting).

  In the above-described embodiment, the display device mounted on the vehicle has been described. However, the display device according to the present invention is installed in a room or the like, and an operator sitting on the right side and an operator sitting on the left side toward the display device. Alternatively, different images can be provided, and different operation button arrangements can be provided.

  Further, in the above-described embodiment, the operation button arrangement for the driver seat and the passenger seat is provided differently. However, the operation button is not limited to a so-called button shape, but is a slide type. Various types of operation input shapes such as switch types and dial types are included.
