  The description will continue with reference to FIG. The touch panel 16 is provided on the front side of the parallax barrier 15, and touch input to the display surface of the dual view display panel including the liquid crystal display panel 14 and the parallax barrier 15 (at a certain position in the display surface by a finger or the like). It is a panel that accepts touch). When a touch input is made on the display surface, the touch panel 16 generates a signal corresponding to the position and sends the signal to the touch position detection circuit 18. This signal generation is realized, for example, by measuring the amount of charge change on the panel surface. In addition, since the touch panel 16 is a well-known thing, description regarding the specific structure is abbreviate | omitted here.

  The touch position detection circuit 18 is a circuit that constitutes a touch input detection unit together with the touch panel 16. The touch position detection circuit 18 generates coordinate data indicating the position (coordinates) on the display surface of the touch input based on a signal sent from the touch panel 16 when the touch input is made, and the coordinate data Is sent to the control unit 10.

  Based on the coordinate data sent from the touch position detection circuit 18, the control unit 10 recognizes the operation content instructed by the touch input, and the liquid crystal controller 11 and the car navigation system as an external device based on the recognition result. 51 and the DVD playback device 52 are controlled.

  Here, the control unit 10 includes a control CPU, a memory, and the like. By executing the control program in these manners, in the control unit 10, the functional blocks shown in FIG.

  That is, the control unit 10 functions as the storage unit 10a, the display control unit 10b, and the input recognition unit 10c.

  The storage unit 10a stores information related to a car navigation video operation screen (first operation screen), a DVD video operation screen (second operation screen), and a selection screen.

  The car navigation video operation screen and the DVD video operation screen are screens displayed on the display unit 17 for operating the car navigation video and the DVD video, respectively, and include display of buttons corresponding to various operations (FIG. 7 described later). a) and FIG. 7 (b) and FIG. 8 (a) and FIG. 8 (b)). When a touch input is made at the position of these buttons, it is considered that these buttons are pressed, and a corresponding operation is executed.

  As information about the car navigation video operation screen and the DVD video operation screen, operation screen data indicating the design of the screen for displaying the screen on the display unit 17, and a button area (button region) included in the screen, respectively. And a table showing the correspondence between the operation contents associated with the button. The button area is defined by coordinates on the display surface.

  The selection screen is a screen displayed on the display unit 17 for selecting which of the car navigation video operation screen and the DVD video operation screen should be displayed, and includes a display of buttons for selecting each operation screen (described later). (See FIG. 6A and FIG. 6B). By performing touch input at the positions of these buttons, it is assumed that these buttons have been pressed, and the corresponding operation screen is selected.

  Information related to the selection screen includes selection screen data indicating the design of the screen to display the screen on the display unit 17, a button area (button region) included in the screen, and a selection associated with the button. A table indicating the correspondence with the contents (car navigation video operation screen or DVD video operation screen) is included. The button area is defined by coordinates on the display surface.

  The display control unit 10b reads the operation screen data or selection screen data from the storage unit 10a and sends the operation screen data or selection screen data to the liquid crystal controller 11, thereby causing the display unit 17 to display a car navigation video operation screen, a DVD video operation screen, or a selection screen. .

  Specifically, the display control unit 10b displays a selection screen when a touch input is made at an arbitrary position on the display surface in a state where neither the operation screen nor the selection screen is displayed.

  The display control unit 10b recognizes that the touch input has been made by a notification from the input recognition unit 10c described later. Note that the display control unit 10b may directly receive the coordinate data from the touch position detection circuit 18 and recognize that the touch input has been made.

  In addition, when the display control unit 10b receives a selection signal from the input recognition unit 10c indicating that the car navigation video operation screen or the DVD video operation screen is selected while the selection screen is displayed, the selected operation is performed. Display the screen.

  When neither the operation screen nor the selection screen is displayed, when the coordinate data is sent from the touch position detection circuit 18, the input recognition unit 10 c displays a signal for notifying that a touch input has been made. Sent to the unit 10b. Note that this signal only needs to notify the display control unit 10b that a touch input has been made, and does not need to be notified to that position.

  Further, the input recognition unit 10c compares the coordinate data sent from the touch position detection circuit 18 with the button area of the displayed selection screen or operation screen when the selection screen or the operation screen is displayed. Thus, the selection content or the operation content instructed by the touch input is recognized, and an instruction according to the recognition result is sent to the display control unit 10b, the car navigation system 51, or the DVD playback device 52.

  Specifically, in a state where the selection screen is displayed, the input recognition unit 10c compares the coordinate data sent from the touch position detection circuit 18 with the button area of the selection screen, thereby performing the touch input. It recognizes which of the car navigation video operation screen and the DVD video operation screen has been selected, and sends a selection signal indicating the recognition result to the display control unit 10b.

  Further, the input recognition unit 10c is designated by touch input by comparing the coordinate data sent from the touch position detection circuit 18 with the button area of the operation screen when the operation screen is displayed. The operation content is recognized and processing corresponding to the operation content is performed.

  In order to know which screen is displayed, the input recognition unit 10c obtains information on the display screen from the display control unit 10b.

  Since the operation content is mainly for the car navigation system 51 and the DVD playback device 52, the input recognition unit 10c mainly sends an operation signal to them. However, the operation content includes an operation for deleting the displayed operation screen and returning to the normal display. In this case, an erasure signal is sent to the display control unit 10b.

  Next, based on the flowchart of FIG. 5, the flow of processing when operating the car navigation video and the DVD video in the dual view display device 1 will be described.

  When performing dual view display of car navigation video and DVD video on the display unit 17, the input recognition unit 10c monitors whether or not touch input has been made at an arbitrary position on the display screen (step S1).

  When the input recognition unit 10c recognizes that a touch input has been made, the input recognition unit 10c notifies the display control unit 10b that a touch input has been made. The display control unit 10b reads the selection screen data from the storage unit 10a and sends it to the liquid crystal controller 11, so that it is superimposed on the car navigation image in the driver seat direction D1, and the DVD image in the passenger seat direction D2. The selection screen is displayed in a window so as to be superimposed (step S2).

  The display states of the selection screen in the driver seat direction D1 and the passenger seat direction D2 are shown in FIGS. 6 (a) and 6 (b), respectively. On the selection screen SP, a “driver's seat side image selection” button SPa for selecting a driver's seat side image (car navigation image) as an operation target and a “passenger's seat” for selecting a passenger's seat side image (DVD image). Side image selection "button SPb. For example, a “driver's seat side video selection” button SPa is displayed in the upper area of the selection screen SP, and a “passenger side video selection” button SPb is displayed in the lower area of the selection screen SP.

  The description will be continued with reference to FIG. When the selection screen SP is displayed, the input recognition unit 10c determines whether or not a touch input is made to the “driver's seat side image selection” button SPa or the “passenger side image selection” button SPb displayed on the selection screen SP. Is monitored (step S3).

  When the operator performs a touch input to the “driver's seat side image selection” button SPa and the input recognition unit 10c recognizes this, the input recognition unit 10c displays and controls a selection signal indicating that the car navigation image operation screen is selected. Send to section 10b. Thereby, the display control unit 10b reads the operation screen data of the car navigation image operation screen from the storage unit 10a, and sends the operation screen data to the liquid crystal controller 11 so as to be superimposed on the car navigation image in the driver seat direction D1. In the passenger seat direction D2, the car navigation image operation screen is displayed in a window so as to be superimposed on the DVD image (step S4).

  The display states of the car navigation video operation screen in the driver seat direction D1 and the passenger seat direction D2 are shown in FIGS. 7A and 7B, respectively. On the car navigation image operation screen CP1, operation buttons necessary for operation of the car navigation image are displayed. The operation buttons include, for example, a “destination” button CP1a, a “registration” button CP1b, and a “return” button CP1c.

  When the car navigation video operation screen CP1 is displayed, the input recognition unit 10c monitors which of the buttons CP1a to CP1c displayed on the car navigation video operation screen CP1 is touched, and the touched button An operation signal indicating an operation in accordance with is sent to the car navigation system 51 or the display control unit 10b.

  Specifically, when a touch input is made to the “destination” button CP1a or the “register” button CP1b, the car navigation system 51 is notified by an operation signal that these operations have been performed. In the car navigation system 51, the car navigation video data output to the liquid crystal controller 11 is changed based on the operation signal.

  When a touch input is made to the “return” button CP1c, the display control unit 10b is notified by an operation signal that this operation has been performed. As a result, the display control unit 10b stops displaying the car navigation video operation screen CP1.

  The description will be continued with reference to FIG. In a state where the selection screen SP is displayed, when the operator performs touch input to the “passenger side video selection” button SPa and the input recognition unit 10c recognizes that, the input recognition unit 10c displays the DVD video operation screen. A selection signal indicating selection is sent to the display control unit 10b. Thereby, the display control unit 10b reads the operation screen data of the DVD video operation screen from the storage unit 10a and sends it to the liquid crystal controller 11, so that it is superimposed on the car navigation video in the driver seat direction D1, and In the passenger seat direction D2, the DVD video operation screen is displayed in a window so as to be superimposed on the DVD video (step S5).

  Here, the display states of the DVD video operation screen in the driver seat direction D1 and the passenger seat direction D2 are shown in FIGS. 8A and 8B, respectively. The DVD video operation screen CP2 displays operation buttons necessary for DVD video operation. The operation buttons include, for example, a “play” button CP2a, a “fast forward” button CP2b, a “rewind” button CP2c, a “stop” button CP2d, and a “return” button CP2e.

  When the DVD video operation screen CP2 is displayed, the input recognition unit 10c monitors which of the buttons CP2a to CP2e displayed on the DVD video operation screen CP2 is touched, and the touched button An operation signal indicating an operation in accordance with is sent to the DVD playback device 52 or the display control unit 10b.

  Specifically, when a touch input is made to the “play” button CP2a, the “fast forward” button CP2b, the “rewind” button CP2c, or the “stop” button CP2d, an operation signal indicating that these operations have been performed. To notify the DVD playback device 52. The DVD playback device 52 performs playback, fast forward, rewind, or stop operation, and changes the DVD video data output to the liquid crystal controller 11 based on the operation signal.

  Further, when a touch input is made to the “return” button CP2e, the display control unit 10b is notified by an operation signal that this operation has been performed. As a result, the display control unit 10b stops displaying the DVD video operation screen CP2.

  As described above, in the dual view display device 1, the car navigation video is displayed in the right direction (first display direction D1) of the display screen, and the DVD video is displayed in the left direction (second display direction D2) ( (See FIG. 3).

  In this state, when the operator touches an arbitrary position on the display screen, as shown in FIGS. 6A and 6B, the display control unit 10b displays the selection screen SP on the car navigation video and the DVD video. Display window at the same time.

  On the selection screen SP, a “driver's seat side video selection” button SPa and a “passenger side video selection” button SPb are displayed. Thereafter, when the operator touches the “driver's side video selection” button SPa, the input recognition is performed. The unit 10c recognizes the touch on the “driver's seat side video selection” button SPa, and the display control unit 10b displays the car navigation video operation screen CP1 and the car navigation video operation screen CP1 as shown in FIGS. 7 (a) and 7 (b). A window is displayed simultaneously on the DVD image. On the car navigation video operation screen CP1, a “destination” button CP1a, a “registration” button CP1b, and a “return” button CP1c are displayed. When the operator touches each button, an operation corresponding to each button is performed.

  When the operator touches the “passenger side video selection” button SP2 displayed on the selection screen SP, the input recognition unit 10c recognizes the touch on the “passenger side video selection” button SP2, and the display control unit 10b. As shown in FIGS. 8A and 8B, the DVD video operation screen CP2 is simultaneously displayed on the car navigation video and the DVD video as a window. On the DVD video operation screen CP2, a “play” button CP2a, a “fast forward” button CP2b, a “rewind” button CP2c, a “stop” button CP2d, and a “return” button CP2e are displayed, and the operator touches each button. Thus, the operation corresponding to each button is performed.

  Thus, by first determining whether or not the display screen has been touched by the operator, and then displaying a selection screen for selecting an operation screen corresponding to the display in each display direction, In a normal display state, it is not necessary to provide a touch dedicated area corresponding to each operation screen, and operability is improved. Further, the operator does not touch the other touch-only area by mistake.

  Further, by displaying the operation screen in the display area in each display direction, the operator can perform an operation on a video different from the video that he / she is observing, and the operability is improved. On the contrary, the operation screen may be displayed only in the display direction corresponding to the selected operation screen.

  In the present embodiment, it is assumed that a car navigation image is displayed in one direction and a DVD image is displayed in the other direction. However, the present invention is not limited to this, as long as separate images are displayed in different display directions. Good. For example, a combination of a TV image and a DVD image, a TV image and a car navigation image, or a combination of a TV image and a TV image may be used. In addition, the video form of the display need not be fixed in each display direction, and the video form may be switched and used. For example, the video displayed in each display direction may be switched between a television video, a DVD video, and a car navigation video.

  In the present embodiment, it is assumed that the selection screen is displayed on the car navigation video and the DVD video. However, the present invention is not limited to this, and the car navigation video and the DVD video are not displayed when the selection screen is displayed. Only the selection screen may be displayed.

  In the present embodiment, it is assumed that the car navigation video operation screen or the DVD video operation screen is displayed on the car navigation video and the DVD video. However, the present invention is not limited to this, and the car navigation video and the DVD video are displayed when the operation screen is displayed. Instead of displaying, only the operation screen may be displayed.

  In the present embodiment, it is assumed that the same selection screen is displayed on the car navigation video and the DVD video. However, the present invention is not limited to this. For example, in the selection screen displayed on the car navigation video, “driver's seat side video selection” ”Button is emphasized more than the“ selection of the passenger side video ”button, and in the selection screen displayed on the DVD video, the“ selection of the passenger side video ”button is emphasized more than the“ selection of the driver side video ”button. May be displayed. By adopting this configuration, the operator can preferentially recognize a button with a high operation frequency, thereby improving operability.

  In the present embodiment, it is assumed that the same operation screen is displayed on the car navigation video and the DVD video. However, the present invention is not limited to this. For example, the car navigation video operation screen displayed on the DVD video is displayed on the car navigation video. The DVD video operation screen that is displayed smaller than the displayed car navigation video operation screen and displayed on the car navigation video may be displayed smaller than the DVD video operation screen displayed on the DVD video. By adopting this configuration, it is possible to reduce the hindrance to the display image due to the operation screen having a low operation frequency, so that the quality of the display image is improved.

  In this embodiment, it is assumed that the selection screen is displayed on the car navigation video and the DVD video at the same time. However, the present invention is not limited to this. For example, the selection screen is displayed on the DVD video later than the car navigation video. You may make it. Further, it is not necessary to fix the display order of the selection screen displayed on the car navigation video and the DVD video, and the display order of the selection screen may be switched. By adopting this configuration, it is possible to reduce the hindrance to the display image by the selection screen for one operator who operates the image less frequently, so that the quality of the display image is improved.

  In the present embodiment, it is assumed that the car navigation video operation screen or the DVD video operation screen is displayed on the car navigation video and the DVD video at the same time. However, the present invention is not limited to this, for example, the car navigation video operation screen displayed on the car navigation video. Is displayed earlier than the car navigation video operation screen displayed on the DVD video, and the DVD video operation screen displayed on the DVD video is displayed earlier than the DVD video operation screen displayed on the car navigation video. I do not care. By adopting this configuration, it is possible to reduce the hindrance to the display image due to the operation screen having a low operation frequency, so that the quality of the display image is improved.

  In the present embodiment, the dual view display is realized by superimposing the parallax barrier 15 on the liquid crystal display panel 14, but the present invention is not limited to this, and separate displays are provided for a plurality of different display directions. Any configuration can be used. For example, the liquid crystal display panel 14 may be overlapped with a lenticular lens, or the liquid crystal display panel 14 may be provided with a plurality of light sources that are repeatedly turned on and off at a desired period.

  In the present embodiment, the display unit 17 is configured by using the liquid crystal display panel 14. However, for example, a CRT, a plasma display panel, an organic EL display panel, or the like may be used instead of the liquid crystal display panel 14. Absent.

  In the present embodiment, the touch panel 16 is formed so as to detect a touch on the display screen by measuring the amount of change in the charge on the panel surface. However, the present invention is not limited to this. It may be configured to detect a touch on the display screen by measuring a voltage change amount or an electromagnetic energy change amount.

  In the present embodiment, the display unit 17 is formed so as to display different images in the left and right directions, but is not limited thereto, and is different from each other in, for example, the left direction, the central direction, and the right direction. It may be formed so as to display an image. By adopting this configuration, the observer can observe different images from three different directions.

  In the present embodiment, it is assumed that once the selection screen or operation screen is displayed, the screen continues to be displayed until the selection screen or operation screen button is touched. For example, if a button on the screen is not touched for a desired time after the selection screen or operation screen is displayed, the display of the selection screen or operation screen may be canceled. By adopting this configuration, the operability is improved because the operator does not have to perform an avoidance operation when the screen is accidentally touched.

[Embodiment 2]
The second embodiment of the present invention will be described with reference to FIGS. 9 to 11 as follows. In the present embodiment, a modification of the operation of the control unit 10 (see FIG. 4) and the stored information in the dual view display device 1 described in the first embodiment will be described. Therefore, the same reference numerals are used for members that are the same as or correspond to the members described in the first embodiment.

  In the present embodiment, two selection screens corresponding to the respective operation screens are provided as selection screens. Therefore, as shown in FIG. 9, the storage unit 10a of the control unit 10 includes two selection screen data created corresponding to the car navigation video operation screen and the DVD video operation screen, respectively. Then, the two selection screens are switched and displayed in a time division manner.

  Based on FIG. 9, functions of the display control unit 10b and the input recognition unit 10c in the present embodiment will be described.

  The display control unit 10b reads the operation screen data or selection screen data from the storage unit 10a and sends the operation screen data or selection screen data to the liquid crystal controller 11, thereby causing the display unit 17 to display a car navigation video operation screen, a DVD video operation screen, or a selection screen. .

  Specifically, the input recognition when the display control unit 10b detects that the touch input is made based on the coordinate data from the touch position detection circuit 18 in a state where neither the operation screen nor the selection screen is displayed. The selection screen is displayed based on the notification from the unit 10a. At this time, the display control unit 10b alternately reads out the selection screen for the car navigation video operation screen and the selection screen for the DVD video operation screen at a predetermined time interval and sends them to the liquid crystal controller 11.

  In addition, when the display control unit 10b receives a selection signal from the input recognition unit 10c indicating that the car navigation video operation screen or the DVD video operation screen is selected while the selection screen is displayed, the selected operation is performed. Display the screen.

  The input recognition unit 10c is not the coordinate value of the coordinate data sent from the touch position detection circuit 18 in the state where each selection screen is displayed, but the timing sent (this timing is the touch input made). The selection is recognized based on the timing. That is, the input recognizing unit 10c does not need to which position the touch input is performed in a state where each selection screen is displayed, and recognizes the selection content based only on the timing when the touch input is performed. .

  Specifically, when the coordinate data is sent from the touch position detection circuit 18 in a state in which each selection screen is displayed, the input recognition unit 10c is used as a selection screen for a car navigation video operation screen. It is identified which of the selection screen and the selection screen for the DVD video operation screen is displayed, recognizes that the operation screen corresponding to the displayed selection screen has been selected, and receives a selection signal indicating the recognition result The data is sent to the display control unit 10b.

  In order to identify which of the selection screen for the car navigation video operation screen and the selection screen for the DVD video operation screen is displayed as the selection screen, the input recognition unit 10c is displayed from the display control unit 10b at that time. You are getting information on the selection screen.

  Further, the input recognition unit 10c compares the coordinate data sent from the touch position detection circuit 18 with the button area of the operation screen displayed at that time while the operation screen is displayed. The operation content instructed by the touch input is recognized, and an instruction corresponding to the recognition result is sent to the display control unit 10b, the car navigation system 51, or the DVD playback device 52. This is the same as in the first embodiment.

  Next, based on the flowchart of FIG. 10, the flow of processing when operating the car navigation video and the DVD video in the dual view display device 1 of the present embodiment will be described.

  When performing dual view display of car navigation video and DVD video on the display unit 17, the input recognition unit 10c monitors whether or not touch input has been performed at an arbitrary position on the display screen (step S11).

  When the input recognition unit 10c detects that a touch input has been made, the input recognition unit 10c notifies the display control unit 10b that a touch input has been made. The display control unit 10b reads out the selection screen data for the car navigation image operation screen from the storage unit 10a and sends it to the liquid crystal controller 11, so that it is superimposed on the car navigation image in the driver seat direction D1, and the assistant In the seat direction D2, the selection screen of the car navigation video operation screen is displayed in a window so as to be superimposed on the DVD video. Then, the display control unit 10b waits for a predetermined time (for example, 3 seconds) to elapse, and this time, reads the selection screen data for the DVD video operation screen from the storage unit 10a and sends it to the liquid crystal controller 11. The selection screen for the DVD video operation screen is displayed in a window so as to be superimposed on the car navigation video in the driver seat direction D1 and on the DVD video in the passenger seat direction D2. By repeating this operation, the two selection screens are alternately displayed in a window on the car navigation video and the DVD video (step S12).

  In the above description, the selection screen for the car navigation video operation screen is displayed first, but the selection screen for the DVD video operation screen may be displayed first.

  The display states of the selection screens in the driver's seat direction D1 and the passenger seat direction D2 are shown in FIGS. 11 (a) and 11 (b), respectively. The selection screen SP1 for the car navigation video operation screen and the selection screen SP2 for the DVD video operation screen are superimposed on the car navigation video in the driver seat direction D1, and on the DVD video in the passenger seat direction D2. As shown, the window is displayed alternately.

  As shown in FIGS. 11A and 11B, the selection screen SP1 for the car navigation video operation screen corresponds to the “driver's seat side video selection” button SPa (see FIG. 6A) in the first embodiment. The selection screen SP2 for the DVD video operation screen corresponds to the “passenger seat side video selection” button SPb (see FIG. 6B) in the first embodiment.

  The description will continue with reference to FIG. When the selection screens SP1 and SP2 are alternately displayed, the input recognition unit 10c performs the touch input timing on the display screen, that is, the touch input is being performed while the selection screen SP1 for the car navigation video operation screen is being displayed. It is monitored whether the selection screen SP2 for the DVD video operation screen is being displayed (step S13).

  When the operator performs a touch input while the selection screen SP1 for the car navigation image operation screen is displayed and the input recognition unit 10c recognizes that, the input recognition unit 10c selects a selection signal indicating that the car navigation image operation screen has been selected. Is sent to the display control unit 10b. Thereby, the display control unit 10b reads the operation screen data of the car navigation image operation screen from the storage unit 10a, and sends the operation screen data to the liquid crystal controller 11, so that it is superimposed on the car navigation image in the driver seat direction D1, and In the passenger seat direction D2, the car navigation image operation screen is displayed in a window so as to be superimposed on the DVD image (step S14).

  When the operator performs touch input while the selection screen SP2 for the DVD video operation screen is displayed and the input recognition unit 10c recognizes that, the input recognition unit 10c indicates that the DVD video operation screen has been selected. A selection signal is sent to the display control unit 10b. Thereby, the display control unit 10b reads the operation screen data of the DVD video operation screen from the storage unit 10a and sends it to the liquid crystal controller 11, so that it is superimposed on the car navigation video in the driver seat direction D1, and In the passenger seat direction D2, the DVD video operation screen is displayed in a window so as to be superimposed on the DVD video (step S15).

  The display states of the car navigation image operation screen and the DVD image operation screen in the driver seat direction D1 and the passenger seat direction D2 are shown in FIGS. 7A and 7B, FIG. 8A and FIG. As shown in b).

  Also in this embodiment, various modifications described in the first embodiment are possible.

  As described above, also in the dual view display device 1 of the present embodiment, the car navigation video is displayed in the right direction (first display direction D1) of the display screen, and the DVD video is displayed in the left direction (second display direction D2). Is displayed (see FIG. 3).

  In this state, when the operator touches an arbitrary position on the display screen, the display control unit 10b alternately displays the selection screens SP1 and SP2 in a window as shown in FIGS. .

  When the operator touches the display surface while the selection screen SP1 is being displayed, the input recognition unit 10c recognizes that the display surface has been touched while the selection screen SP1 is being displayed. As shown in FIG. 7B, the car navigation video operation screen is simultaneously displayed on the car navigation video and the DVD video.

  When the operator touches the display surface while the selection screen SP2 is displayed, the input recognition unit 10c detects that the display surface is touched while the selection screen SP2 is displayed, and the display control unit 10b displays the operation screen display. The control means simultaneously displays the DVD video operation screen on the car navigation video and the DVD video as shown in FIGS. 8A and 8B.

  Thus, by recognizing the operation screen from the selection screen displayed when the display surface is touched, the operator can select the operation screen without being aware of the position of the touched display surface. Therefore, operability is improved.

  Since other effects are the same as those of the first embodiment, description thereof will not be repeated here.

[Embodiment 3]
A third embodiment of the present invention will be described below with reference to FIGS. In the present embodiment, the operation of the control unit 10 (see FIG. 4) in the dual view display device 1 described in the first embodiment and other modified examples of stored information will be described. Therefore, the same reference numerals are used for members that are the same as or correspond to the members described in the first embodiment.

  In this embodiment, the selection screen is not displayed, but the operation screen is selected based on the number of touch inputs to the display surface within a predetermined time. Therefore, as shown in FIG. 12, the storage unit 10a of the control unit 10 stores a table indicating the correspondence between the number of touches and the selection content as selection information. That is, the number of touches (one time) when selecting the car navigation video operation screen and the number of touches (two times) when selecting the DVD video operation screen are stored.

  Specifically, when the input recognition unit 10c does not display any operation screen and a touch input is made at an arbitrary position on the display surface, within a predetermined time (for example, within 1 second) from that point. Count the number of times touch input is made (also count the first touch input).

  Then, the input recognition unit 10c refers to the count result and a table stored as selection information in the storage unit 10a, and selects the selection contents (car navigation video operation screen or DVD video operation screen) associated with the number of times. recognize. Then, the display control unit 10b displays a car navigation video operation screen or a DVD video operation screen recognized as being selected.

  As described above, the position at which the touch input is performed is not important, and a specific operation screen may be displayed according to the number of touch inputs detected within a predetermined time.

  In addition, the input recognition unit 10c compares the coordinate data sent from the touch position detection circuit 18 with the button area of the operation screen displayed at that time while the operation screen is displayed. The operation content instructed by the touch input is recognized, and an instruction corresponding to the recognition result is sent to the display control unit 10b, the car navigation system 51, or the DVD playback device 52. This is the same as in the first embodiment.

  Next, based on the flowchart of FIG. 13, the flow of processing when operating the car navigation video and the DVD video in the dual view display device 1 of the present embodiment will be described.

  When performing dual view display of car navigation video and DVD video on the display unit 17, the input recognition unit 10 c monitors whether or not touch input is performed at an arbitrary position on the display surface, and when touch input is performed. The number of times touch input is made within one second from that point is counted (step S31).

  When the touch input made per second is one time (that is, only the first touch input), the display control unit 10b reads the operation screen data of the car navigation video operation screen from the storage unit 10a and sends it to the liquid crystal controller 11. Thus, the car navigation video operation screen is displayed in a window so as to be superimposed on the car navigation video in the driver seat direction D1 and on the DVD video in the passenger seat direction D2 (step S32).

  On the other hand, when the touch input made for one second is twice, the display control unit 10b reads the operation screen data of the DVD video operation screen from the storage unit 10a and sends it to the liquid crystal controller 11, thereby driving the driver seat direction D1. In step S33, the DVD image operation screen is displayed in a window so as to be superimposed on the car navigation image in step S2 and on the DVD in the passenger seat direction D2.

  The reason why the case where the touch input is once is associated with the car navigation image operation screen and the case where the touch input is twice is associated with the DVD image operation screen is that the operation of the car navigation image is generally more frequently used. This is because it is easier to operate if the car navigation video operation screen is associated with a smaller number of touch inputs.

  The display states of the car navigation image operation screen and the DVD image operation screen in the driver seat direction D1 and the passenger seat direction D2 are shown in FIGS. 7A and 7B, FIG. 8A and FIG. As shown in b).

  Also in this embodiment, various modifications described in the first embodiment are possible.

  As described above, also in the dual view display device 1 of the present embodiment, the car navigation image is displayed in the right direction (first display direction D1) of the display surface, and the DVD image is displayed in the left direction (second display direction D2). Is displayed.

  In this state, when the operator touches an arbitrary position on the display surface once per second, the display control unit 10b displays the car navigation video operation screen as shown in FIGS. 7 (a) and 7 (b). A window is simultaneously displayed on the car navigation image and the DVD image.

  When the operator touches an arbitrary position on the display screen twice per second, the display control unit 10b displays the DVD video operation screen as a car navigation video as shown in FIGS. 8 (a) and 8 (b). And window display on the DVD image simultaneously.

  Thus, by counting the number of times the display surface is touched within a predetermined time and recognizing the operation screen from the number of touches, the operator can select the operation screen directly without going through the selection screen. Can do.

  Since other effects are the same as those of the first embodiment, description thereof will not be repeated here.

  In the present embodiment, the display screen is formed so as to determine whether the display surface is touched once or twice per second. However, the present invention is not limited to this. Anything can be used as long as it can be identified. For example, it may be formed so as to determine whether the number of times the display surface has been touched is once or twice or more in 2 seconds.

  In this embodiment, the selection screen is recognized according to the number of times the display surface is touched. However, the present invention is not limited to this, and a temporal pattern of touch input, for example, a temporal length of touch input. The selection screen may be recognized according to the above. Specifically, if the time touched on the display surface is less than 1 second, the car navigation image operation screen is recognized as being selected, and if the time touched on the display surface is 1 second or longer, a DVD image is displayed. The configuration may be such that the operation screen is recognized as being selected.

  As described above, it can be said that the display device of the present invention specifically described in Embodiments 1 to 3 has the following configuration.

A selection screen display control means for displaying the selection screen for each display direction; and when the selection screen is displayed, when a touch input is made to the selection screen, Operation screen display control means for displaying a specific operation screen is provided.

  By adopting this configuration, in the non-display state of the operation screen and the selection screen, the operator only has to touch an arbitrary position on the display surface, so that an erroneous operation by the operator is less likely to occur. In addition, since it is not necessary to always display the selection screen, it is possible to avoid the influence on the video for viewing.

  In the above configuration, the touch input detection unit includes a touch position detection unit that detects a touch input position on the display surface of the display panel, and the operation screen display control unit is configured to perform a touch input to the display selection screen. A configuration may be adopted in which a specific operation screen is displayed based on the position.

  By adopting this configuration, the operator can select a specific operation screen without being aware of the timing of touching the screen, so that the operability can be improved.

  In the above configuration, the selection screen display control means is configured to switch and display a plurality of the selection screens in a time-sharing manner, and the operation screen display control means touches the display surface of the display panel. A configuration may be adopted in which a specific operation screen is displayed from a display selection screen when an input is made.

  By adopting this configuration, the operator can select a specific operation screen without being aware of the position of the screen to be touched, so that the operability can be improved.

  The display device of the present invention is a display device including a display panel that can simultaneously display different images in a plurality of different display directions, and a touch input detection unit that detects a touch input to the surface of the display panel. And the structure which displays a specific operation screen based on the touch input pattern to the display surface of the said display panel may be sufficient.
