Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly to the structure of its operation switch.

[0002]

2. Description of the Related Art FIG. 3 shows an example of a conventional vehicle-mounted display device housed in a chassis of 1 DIN size (opening width 180 mm, height 50 mm). The display panel 4 shown in the figure is supported by the drive unit 2 so as to be rotated around the rotation center axis 3. The drive unit 2 rotates the display panel 4 and also horizontally moves itself in and out of the chassis 1.

That is, the drive unit 2 is inserted into the chassis 1 while the display panel 4 is supported horizontally, and the display panel 4 is housed in the chassis 1. Also,
The display panel 4 is projected horizontally from the housed state, and the display panel 4 is further rotated to be in a used state as shown in the drawing. The arrow in the figure indicates the moving state of the display panel 4.

A display unit 6 is housed in the display panel 4, and operation buttons 5, 5 ... Are arranged on the surface thereof. FIG. 4 is a sectional view showing the inside of the display panel 4. As shown in the drawing, a tact switch 7 attached to a printed circuit board 8 is arranged behind the operation button 5. The printed circuit board 8 and the display unit 6 are arranged on the rear side of the display unit 6 with a code (not shown).
It is connected to the.

The display unit 6 is a printed circuit board 9
Various characters and figures are displayed according to the signal from, and the tact switch 7 is turned on / off by the operation button 5 and outputs a signal for operation to the printed circuit board 9.

[0006]

The in-vehicle display device housed in a 1DIN size chassis has a display panel whose surface is limited to a narrow range, and the display unit has an effective display surface considerably smaller than its outer shape. Therefore, when a large-screen display unit is used, in the above-mentioned conventional vehicle-mounted display device, the place where the operation buttons are arranged avoiding the place of the display unit becomes extremely narrow, and the size and number of the operation buttons are limited, which is remarkable. It was a device with poor operability. Also,
There was a problem that the operation switch could not be arranged when trying to incorporate a display unit of a certain size or more.

Further, if the tact switch is used, many components such as the tact switch 7, the operation button 5 and the printed circuit board 8 are required, which causes a problem of high manufacturing cost.

The present invention has been made in view of the above points, and an object thereof is to use a display unit having a large screen by effectively utilizing the display surface and the non-display surface of the display unit. Even in many cases, various kinds of operation switches can be arranged to provide a display device with good operability. Another object of the present invention is to provide a display device in which the number of parts of the operation switch is small and the manufacturing cost is low.

[0009]

According to the display device of the present invention, a touch panel is arranged over a display surface of a display and a non-display surface on an extension thereof, and a switch operation position and its function are provided on the non-display surface or the touch panel on the non-display surface. Is printed and the touch panel on that portion is used as a switch having a fixed function, and the touch panel on the display surface is used as a switch displayed on the display.

[0010]

According to the display device of the present invention, the touch panel is arranged on a portion of the surface of the display unit other than the display surface of the display unit and is used as a switch having a fixed function. A space for arranging the operation switch can be secured even when the display unit of the screen is used.

Further, since the upper part of the display surface of the display of the touch panel is used as the switch for changing the function, a wide space can be secured, the number of kinds of switches can be increased, and the switching state of the function is displayed on the display. This makes the function clear and easy to use.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An on-vehicle display device which is an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an in-vehicle display device which is an embodiment of the present invention.
Members having the same functions as those of the conventional device shown in FIG. 3 are designated by the same reference numerals. The display panel 4 is horizontally and rotationally driven by the drive unit 2 similarly to the conventional device, and is moved in and out of the chassis 1 of the 1DIN standard. The figure shows the usage state of the display panel 4.

As shown in FIG. 2, the display panel 4
A display unit 6 is housed inside, a touch panel 10 is arranged so as to cover the front surface thereof, and is connected to a printed circuit board 9 by a flexible cord 11.

The touch panel is a device which is usually installed on the display screen of a display device, detects the position of the user's finger when touched, and inputs the screen position information to the computer. It is placed above the hidden surface.

The area indicated by A in FIG. 2 is the display surface of the display, and the window 4a of the display panel 4 is provided in that area. As shown in detail in FIG. 1, windows 4b and 4c are provided in addition to the window 4a, and the touch panel in that portion is used as a switch whose function is fixed.
That is, the back surface of the touch panel 10 is printed and used as a fixed operation button.

As such a fixed switch, a switch for switching between a car navigation screen and a TV screen or a liquid crystal screen portion for switch display is displayed by superimposing an image of the switch on a navigation map screen or a TV screen, that is, an on-screen. There is a switch to instruct.

The touch panel in the window 4a portion is used as a switch for the function shown by the image of the switch displayed on the display screen, and the function can be changed by the display.

Although the embodiment is configured as described above, the invention is not limited to this. For example, instead of the non-display surface of the display, the surface of another member may be arranged under the touch panel. Instead of printing on the back side, it may be printed on a member below the touch panel.

[0019]

According to the display device of the present invention,
A touch panel is placed on the surface of the display unit other than the display surface, and it is used as a switch with fixed functions.Therefore, even when the surface of the display unit is effectively used and a large-screen display unit is used, the operation switch is used. You can secure a space to place it.

Further, since the upper part of the display surface of the touch panel is used as the switch for changing the function, a wide space can be secured, the number of types of the switch can be increased, and the display of the function switching state can be displayed. This makes the function clear and easy to use.
