In this case, when the image reaching the list box 150 is recognized as the selected image, the display surface 120 is switched to a new function display corresponding to the selected image by clicking the image with the cursor, and the image selection is performed. The operation is being performed.

  In such a scroll operation of a large number of selection candidate data images, the selection candidate images can be scrolled sequentially in the center of the list box, and the selection image can be found from among the selection candidate images. The part of is not visually observed. In view of this, it is possible to magnify and display a portion of the display surface on the monitor that is the object of visual observation, and to display a large number of selection candidate images on the peripheral display surface with a relatively small number of selections. The operation of finding the selected image from the candidate images becomes easy. From this point of view, there is a demand for enlarging and displaying a partial region of the display surface 120. However, neither the conventional monitor nor the monitors disclosed in Patent Documents 1 and 2 can solve the above-described problem.

  The present invention has been made paying attention to the above-mentioned problems, and the object of the present invention is to display images even when the display surface on the monitor is viewed from a direction deviated from the orthogonal direction with a relatively simple configuration. To provide an image display device in which the main part can be viewed relatively easily, and further, the main part of the display image is enlarged and displayed to facilitate the image selection operation in the case of an operation panel of an in-vehicle device. is there.

That is, the display surface 7 of the monitor 3 is arranged on the inner side (see FIG. 9) by a predetermined amount with respect to the display opening 6 provided in the instrument panel 1 so as to protrude from the instrument panel 1. Compared with a monitor (not shown), it is possible to improve the visibility of the enlarged display image of the display surface 7 and the convex lens 9 described later against the backlight from the windshield 8.

Further, the monitor housing portion 2 recessed in the instrument panel 1 has a display opening 6 that is sufficiently larger than the display surface 7 in both length and width. Here, in particular, a convex lens 9 having a curved surface protruding by a predetermined amount h (see FIG. 5) is attached to the display surface 7 in an overlapping manner, and an enlarged display area A (see FIG. 6) where the convex lens 9 overlaps. Is enlarged on the other display surface 7 and displayed on the surface of the convex lens 9.
The translucent panel 11 (see FIGS. 1, 3, and 9) is disposed close to and opposed to such an extent that it does not interfere with the convex lens 9 on the monitor 3.

  The translucent panel 11 covers the entire display opening 6 and also continuously covers the upper extension portion of the display opening 6. As shown in FIGS. 1, 3, and 9, the translucent panel 11 is interposed via the curved edge frame 12. Fastened to the entire periphery of the opening edge a of the instrument panel 1. As shown in FIG. 9, the curved edge frame 12 has an engagement step portion 121 fitted to the entire periphery of the opening edge portion a of the instrument panel 1 and the entire periphery of the opening edge portion a of the instrument panel 1 with a predetermined width. The outer flange 122 to cover and the latching | locking part 123 which latches the translucent panel 11 to the back surface of the outer flange 122 are comprised, and the whole shape by planar view comprises the substantially U-shaped frame shape which curves. As shown in FIGS. 1 and 3, the substantially U-shaped curved edge frame 12 protrudes toward the passenger compartment R side, and a pair of left and right air outlet duct ports 13 are integrally formed at the left and right ends. A projecting frame 124 that serves both as a reinforcing function and assures an aesthetic appearance is formed on the windshield 8 so as to project upward.

As shown in FIGS. 1 and 3, the translucent panel 11 includes a front display area e1 facing the monitor 3, an inclined display area e2 extending obliquely upward from the upper edge, and a windshield 8 from the upper edge. And an upward region e3 extending to the side.
This translucent panel 11 is gradation-painted on the upper end side of the upward area e3 and the vicinity of the left and right edges of the inclined display area e2 and the front display area e1, and is coated so that the translucency increases toward the center from the edge, The aesthetics are secured. Further, the EL sheet 11f is overlapped and joined to the lower surface of the translucent panel 11 and the lower side of the upward area e3 and the subsequent inclined display area e2, and the EL sheet is transmitted through the translucent panel 11. The appearance is improved by 11f emission. The lower part of the tilt display area e2 is secured as a map display area ea dedicated to a navigation device (not shown).
A second liquid crystal display panel for map display (not shown) is provided inside the lower part of the back side of the map display area ea, and the second liquid crystal display panel is connected to the operation ECU 4.

Here, the monitor 3 (liquid crystal display device) and the convex lens 9 emit light so that an occupant seated in the driver's seat or the front passenger seat can easily view the image, so that the occupant is easily seated. The main part of the display surface 7 is visually observed. In addition, since the structure of the monitor 3 (liquid crystal display device) is well-known, description is abbreviate | omitted about the detailed structure of a liquid crystal display device.
The convex lens 9 mounted on the display surface of the monitor 3 (liquid crystal display device) is preferably made of glass or transparent synthetic resin and has a small chromatic aberration.
The convex lens 9 enlarges the image of the enlarged display area A that overlaps the convex lens 9 on the display surface 7, and is set to enlarge at a magnification of about 1.2 to 3 times, for example. In particular, chromatic aberration is not a concern when zooming in at a magnification of about 1.5 to 3 times.

As shown in FIGS. 6 (a), 7 (a), and 8 (a), the convex lens 9 here is disposed in such a manner that all the parts within the aperture face the rectangular display surface 7 of the monitor. That is, the convex lens 9 is arranged so that the aperture rm is smaller than the vertical width c1 of the rectangular display surface 7 having a short vertical width and overlaps the center of the display surface 7. Here, the convex lens 9 is formed by extending a peripheral plate piece 90 having a constant thickness from the outer peripheral edge of the lens portion so as to cover the entire display surface 7 (vertical width c1, horizontal width c2). Attachment to the monitor 3 is facilitated via an attachment groove 40 described later.
The convex lens 9 having such a configuration has a relatively small magnification, but the number and amount of images displayed on the entire display surface 7 are not changed, and only the image of the enlarged display area A is enlarged. Can be displayed with good visibility. Moreover, as shown by a two-dot chain line in FIG. 6A, the center of the enlarged display area A of the display surface 7 of the monitor 3 is enlarged and displayed from the other display surface portions in the upper, lower, left and right directions, and is shown in FIG. In this way, it is displayed on the convex curved surface. For this reason, even when not looking directly from the perpendicular Lo that is orthogonal to the display surface of the monitor, that is, from the oblique direction from the driver seat direction b1 or the passenger seat direction b2, the image in the enlarged display area A is enlarged and viewed. It can be confirmed well.

  Incidentally, as shown in FIGS. 6B, 7B, and 8B, the aperture rm1 of the convex lens 9a may be set larger than the vertical width c1 of the display surface 7. In this case, the convex lens 9a is formed by cutting at portions facing both lateral edges of the rectangular display surface 7 having a short vertical width c1. In this case, the rectangular display surface 7 having a short vertical width is covered with a convex lens 9a having a relatively large aperture. In this case, as indicated by a two-dot chain line in FIG. 6B, images before and after the enlarged display in the vertical direction are lacking, but this is particularly effective when the magnification of the lens 9a is increased to display an image extending in the horizontal direction. is there.

  As shown in FIGS. 6A and 6B, the convex lens 9 may be overlapped and fixed over the entire display surface 7. Here, in particular, as shown in FIGS. 6A and 6B, rail members 41 having mounting grooves 40 that are long in the vertical direction are formed on the left and right ends of the base frame 301 on the monitor 3 side. Here, the mounting groove 40 can be fitted so that the left and right peripheral plate pieces 90 can be inserted / removed from above, and the left and right peripheral plate pieces 90 of the convex lens 9 are bottomed in a state where the convex lens 9 is overlaid on the entire display surface 7. 401 is formed to be locked. As described above, since the peripheral plate piece of the convex lens 9 and the convex lens 9a can be detachably fitted into the mounting groove 40, a plurality of convex lenses 9 and convex lenses 9a having different apertures and magnifications can be selectively attached and detached, which is suitable for images. Lens can be easily adopted.

As shown in FIG. 2, the operation ECU 4 functions as an input device for operating various in-vehicle devices such as an air conditioner (hereinafter referred to as an air conditioner), a navigation device, an audio device, and a television device mounted on the vehicle. At this time, an image corresponding to a predetermined function is displayed via the monitor 3 (liquid crystal display device) and a second liquid crystal display panel (not shown) (not shown).
Further, a horizontal cursor scanning member 14 for operating a horizontal cursor (reference symbol Kh in FIG. 4A) for an occupant to perform an input operation on the display surface 7 of the monitor 3 (liquid crystal display device) in accordance with the display mode; A vertical cursor for operating the vertical cursor (reference symbol Kv in FIG. 4B) and the scanning member 15 are connected to the operation ECU 14 as an operation switch MS. Here, as shown in FIG. 3, the horizontal cursor scanning member 14 and the vertical cursor scanning member 15 are arranged at two places on the left and right when the steering handle 16 is at the reference position (position shown in FIG. 3).

As shown in FIG. 10, the horizontal cursor scanning member 14 and the vertical cursor scanning member 15 have the same shape and structure, and the both ends d1 and d2 are pushed and held, respectively, so that scanning to one side and the other side can be performed. When an instruction is issued to continue and the center portion d3 is pressed, a click signal can be input.
By switching between the horizontal cursor scanning member 14 and the vertical cursor scanning member 15, a plurality of selection switches and selection images on the display surface 7 in the monitor 3 (liquid crystal display device) are clicked, and the cursors Kh, Kv (FIG. 4) are clicked. The operation ECU 14 can be instructed to input instruction signals such as switching, selection, and feeding. Note that, for example, another operation panel mp (see FIG. 2) may be supplementarily provided in the instrument panel 1 or in the vicinity thereof to increase the functionality.
Here, the operation ECU 14 switches a plurality of menu buttons (see FIG. 4) m1 to mn by a switching operation of the horizontal cursor scanning member 14 and the vertical cursor scanning member 15, and air conditioner, navigation device, audio device, television device, etc. Is selectively controlled.

  That is, as shown in FIG. 2, the operation ECU 4 is configured by a known microcomputer including a CPU 401, a ROM 402, a RAM 403, and a bus line 404 that connects these components. The operation ECU 4 includes a display control unit 411 that drives the monitor 3 (liquid crystal display device) to display an operation panel mp of an air conditioner, a navigation device, an audio device, a television device, etc. on the display surface 7, an operation panel, etc. A display data storage unit 412 for storing display data, a horizontal cursor scanning member 14 and a vertical cursor scanning member 15, and a switching signal from a plurality of switches arranged on another instrument panel (not shown), and an image on the display surface An image processing unit 413 that switches between a predetermined mode and a communication unit for performing data communication with in-vehicle devices such as an air conditioner ECU 41, a navigation ECU 42, an audio ECU 43, and a television ECU 44 via a communication line 414 wired to the vehicle. 415, an audio control unit 416 for controlling the audio signal of the speaker 17, and an EL sheet Illumination control unit 417 is provided for emitting control 3.

  The operation ECU 4 displays an operation panel image for operating the selected in-vehicle device on the monitor 3 (liquid crystal display device) by the operation of the CPU 401 and arranges it on the horizontal and vertical cursor scanning members 15 and an instrument panel (not shown). By identifying the operation command issued by the occupant by the plurality of switch operation devices provided and transmitting the operation command to the air conditioner ECU, navigation ECU, audio ECU, television ECU, etc., through each of these ECUs, It operates to control air conditioners, navigation devices, audio devices, televisions, etc. mounted on vehicles.

Hereinafter, the operation when the operation ECU 14 receives an operation command from the occupant will be described. In executing the control process, the display data storage unit 412 selects an in-vehicle device (operation target device) that the occupant wants to operate as operation panel data for an air conditioner, a navigation device, an audio device, a television, or the like. Operation target device selection image for operation, operation type selection image for selecting what the operation target device is to be operated by the occupant, and operation command input image corresponding to the operation type selected by the occupant Is stored in memory.
For example, if the CPU 401 starts the control process, the display data of the operation target device selection image is read from the display data storage unit 412, and the display data is output to the display control unit 411. The target device selection image is displayed. In this case, since the operation target devices are an air conditioner, a navigation device, an audio device, and a television device, a selection block representing these devices is displayed on the display surface 7, and the driver uses the horizontal cursor scanning member 14 and the vertical cursor. The scanning member 15 is operated, and a desired in-vehicle device is selected with a cursor and clicked.

First, assume that a television device is selected as the in-vehicle device. In this case, as shown in FIG. 4B, a plurality of operation switches s1 to s4 set on the peripheral edge of the display surface 7 are selected by the horizontal cursor scanning member 14 and the vertical cursor scanning member 15, and the volume, illuminance, Levels such as hue and channel setting are selected and set from a level display area (not shown). Further, a plurality of channel buttons ch1 to ch12 displayed in a predetermined pattern near the lower edge of the display surface 7 are moved in the horizontal direction in conjunction with the horizontal cursor scanning member 14 scanning the horizontal scroll 50.
In this case, the cursor Kv is set in advance in the central enlarged display area A, and the channel button ch6 (FIG. 4B shows an example of the channel switching state) reached here can be particularly enlarged and displayed with good visibility. The occupant can confirm the channel button ch6 on the display surface 7 of the monitor 3 and click it (by pressing d3 at the center of the horizontal cursor scanning member 14) to switch the channel. Moreover, since the image displayed in the enlarged display area A is displayed on the convex curved surface as shown in FIG. 5, the image of the enlarged display area A also from the oblique direction from the driver seat direction b1 or the passenger seat direction b2. It is possible to see with good visibility by enlarging.

Furthermore, since the channel button ch6 reaching the central enlarged display area is enlarged and the left and right channel buttons ch1, ch12, etc. are displayed small, a relatively large number of channel buttons can be displayed on the limited display surface 7. Channel switching is facilitated.
Next, it is assumed that, for example, an audio device is selected as the in-vehicle device.
When this audio device is selected, as shown in FIG. 4A, menu buttons m1 to mn for audio operation menus are provided on the left and right of the display surface 7, and menu selection is performed in the central enlarged display area A. Previous predetermined patterns, for example, globe display, plain display, etc. are made.

  Next, when the music field selection button oa is selected from the audio operation menu by the horizontal cursor scanning member 14 and the vertical cursor scanning member 15, and is turned on, the center enlarged display area A is divided into a plurality of downward directions. A music field display section (a large number of rectangular area display portions indicated by two-dotted lines in FIG. 4A) is displayed. At this time, the central portion of the enlarged display area A in the vertical direction is most magnified and the vertical cursor scanning member 15 is operated so that the cursor Kh coincides with the portion, and this is clicked (the center of the vertical cursor scanning member 15 is clicked). By switching (d3), the music field can be switched.

Next, when a music field is selected, a plurality of music display parts (for example, a large number of rectangular area display parts indicated by two-dot chain lines in FIG. 4A) are displayed. The vertical cursor scanning member 15 is operated so that the music display portion enlarged in the central portion coincides with the cursor Kh, and this is clicked (d3 is pressed in the center of the vertical cursor scanning member 15) to select the music. The The performance sound and sound of the selected song are heard by the occupant through the speaker 17 controlled by the sound control unit 416.
In this case, as shown in FIG. 5, the music display portion displayed in the enlarged display area A is displayed on the convex curved surface, so that the enlarged display area can also be viewed from the diagonal direction from the driver seat direction b1 or the passenger seat direction b2. The tune display portion of A can be enlarged and viewed with good visibility.

  Even when other in-vehicle devices such as an air conditioner are displayed on the display surface 7 of the monitor 3, as described above, the image displayed in the enlarged display area A is enlarged and displayed from the area of the other display surface. The image of the enlarged display area A can be enlarged and viewed with high visibility from an oblique direction from the seat direction b1 and the passenger seat direction b2. Moreover, only the image reaching the central enlarged display area A is enlarged, and the images before and after the left and right are not enlarged, and are displayed relatively small. In other words, when a large number of small-section displays such as a large number of sinem images are displayed on the limited display surface 7, a relatively large number of relatively small numbers are displayed on the limited display surface 7 than when the display surface is simply enlarged. The small section display can be displayed, and the selection operability is improved.

In the above description, the configuration in which one convex lens 9 is disposed opposite to the monitor 3 formed of a liquid crystal display device has been described. However, in some cases, as shown in FIG. 11, two monitors 3b and 3b are provided side by side on the skeleton 5 in the instrument panel, and they are mounted so that their directions are different from each other toward the driver seat b11 and the passenger seat b21. Further, a configuration may be adopted in which the front surfaces thereof are covered with a single convex lens 9b.
In this case, the same screen may be displayed on the driver's seat b11 and the passenger seat b21, or different images may be displayed respectively. In particular, since the convex lens 9b protrudes relatively large, the driver seat b11 and the passenger seat Each occupant of b21 can easily view an enlarged image with high visibility. In addition, since a single lens is used, the structure can be made relatively compact.

In the above description, the monitor 3 formed of a liquid crystal display device has been described. However, in some cases, a CRT may be used and a convex lens 9 may be disposed so as to face the display surface. The following effects can be obtained.
