Description

  The present invention relates to a touch panel display device that can be used for both a car navigation system and a personal computer capable of pen touch input.

  In a car navigation system or the like, a touch panel is used, and a driver can easily operate by touching a predetermined portion of the touch panel with a finger. The in-vehicle touch panel has a high temperature inside the vehicle. Therefore, due to a heat problem, the reinforced film structure in which the contact surfaces of the touch panel are laminated together cannot be adopted, and the in-vehicle touch panel is configured by only one layer. This is because, when a plurality of layers are bonded together, the resistance to a concentrated load on the touch panel is improved, but at a high temperature, the touch panel portion where the plurality of layers are bonded is easily peeled off, resulting in a problem.

  In car navigation, in consideration of the use of a driver, input using a pen is unnecessary, and there is no problem by using only finger touch input as a specification. That is, since the pen touch input in which a load is intensively applied to a portion having a small contact area is unnecessary, even the above-described single-layer type touch panel is sufficient in terms of durability. The part adjacent to the touch panel frame is particularly vulnerable to the above-mentioned touch resistance, but in applications dedicated to car navigation, this problem can be avoided by setting the operation specifications to avoid operations on this adjacent part. there were.

  On the other hand, as is well known, devices with a touch panel such as a tablet PC are also sold in personal computers. In the case of a tablet PC, as in the case of a personal computer, it is necessary to point to a fine part on the screen like a point instruction with a mouse. Since a pen touch input places a load on a small contact area, a touch panel used in a personal computer has a reinforced film structure in which a plurality of touch panel contact surfaces are laminated.

  Patent Document 1 discloses a touch panel device that improves durability. In the technique described in Patent Document 1, the dot spacer sandwiched between two transparent conductive films is peeled off from the base when an on / off switch operation, that is, contact with and release from the touch panel is repeated a predetermined number of times or more. It addresses the problem.

JP 2002-229736 A

  The technique of Patent Document 1 is effective for improving the resistance of the touch panel due to the peeling and dropping of the dot spacers. However, in the multi-layer bonded touch panel, the countermeasure against the resistance due to the peeling at a high temperature is as follows. Not applicable.

  If it is a car navigation dedicated machine, a single-layer touch panel may be adopted, and a multi-layer touch panel may be adopted if it is a device that is not supposed to be mounted on a vehicle, such as a personal computer. In other words, a device that performs an operation that repeats a touch with a relatively large contact area, such as a finger, can adopt a one-layer touch panel with priority given to thermal problems, and has a small contact area such as pen touch input. A multi-layer touch panel can be adopted with priority given to mechanical resistance if it is a device that repeats touches and operates to touch the part adjacent to the touch panel frame. It turns out that.

  However, when designing a personal computer combined car navigation system, that is, when repeatedly using pen touch input and simultaneously using at high temperatures, both touch panels perform the same operations as before. If this happens, problems will occur. As a particularly prominent case, there is a problem that important control parts such as a window closing button and a scroll bar displayed by an application of a personal computer or an operating system appear in a peripheral part of a touch panel having low mechanical resistance.

  The present invention has been made in view of these points, and an object of the present invention is to provide a touch panel display device that can be switched and used as a car navigation system or a personal computer.

  The information processing apparatus with a touch panel display panel according to the first aspect of the present invention displays a display location where a touch operation can be performed in an outer peripheral region from the outermost peripheral portion of the display area of the display panel to a portion inside a predetermined distance. An information processing apparatus with a touch panel display panel, characterized in that means for preventing a touch operation on the display location is provided.

  In the information processing apparatus with a touch panel type display panel according to the second aspect of the present invention, the display location where the touch operation is possible is a software end button or a scroll bar displayed by a computer operating system or application software. And

  The information processing apparatus with a touch panel display panel according to the third aspect of the present invention displays a display location where a touch operation can be performed in an outer peripheral region from the outermost peripheral portion of the display area of the display panel to a portion which is inward by a predetermined distance. An operation location monitoring unit that monitors whether the display location is displayed, and the display location so that the display location cannot be touch-operated when the operation location monitoring means determines that the display location is displayed in the outer peripheral area. It has a disturbing area display means for displaying a disturbing area that shields the screen.

  The touch panel type display panel with a first frame of the present invention is a touch panel type display panel covered with a frame-like frame, wherein the frame is transparent at a predetermined inner portion and is not at the outer peripheral side of the transparent inner portion. It is characterized by being transparent.

  ADVANTAGE OF THE INVENTION According to this invention, the touch panel apparatus which can use both under high temperature and the use by a pen touch input can be provided by making the pen touch input into the peripheral part of a touch panel with weak mechanical tolerance impossible.

  First, the structure of a conventional touch panel will be briefly described while comparing FIG. 4 and FIG. FIG. 4 is a cross-sectional structure of a touch panel applied to a conventional pen input type display. FIG. 5 is a cross-sectional structure of a touch panel employed in the car navigation system used in the present invention. 4 and 5 are cross-sectional views corresponding to the cross-sectional view of the embodiment of the present invention shown in FIG. 2 when the DD cross section shown in FIG. 1 is viewed from the arrow direction.

  In the touch panel 1 of FIG. 4, an ITO film 16 is applied or adhered to a glass 17 which is a transparent substrate, and an ITO film 12 is applied to or adhered to the film 11. These two ITO films are bonded to each other at the outer periphery of the touch panel via a resist 15, a double-sided tape 14, and an adhesive called silver bond. The characteristic part of the touch panel 1 is that a film 18 is further bonded to the outside of the film 11. This film 18 has an effect of being integrated with the film 11 to increase the strength of the entire film and improving the writing quality of pen touch input. A number of transparent minute dot spacers (not shown) are arranged between the two ITO films. By touching the film with a finger or a pen, the space created by the dot spacers is narrowed, the upper and lower ITO films are connected, and the touch panel mechanism for detecting the input position is well known. A liquid crystal panel 18 is provided at the lower part of the touch panel, and constitutes a touch panel type display device.

  The touch panel 2 in FIG. 5 is a touch panel used in a conventional car navigation system. When compared with the touch panel of FIG. 4, the glass 17 is the same 27, the ITO film 16 is the same 26, the resist 15 is the same 25, the double-sided tape 14 is the same 24, the silver bond 13 is the same 23, and the ITO film 12 Corresponds to 22, the film 11 corresponds to 21, and the liquid crystal panel 18 corresponds to 28. The difference is that there is no film corresponding to the film 18 that is stuck to the outside of the film 11. This is because the touch panel 2 used for car navigation must withstand a high temperature environment in the passenger compartment, and thus it is difficult to adopt a film bonding structure. This is because there is a problem that the laminated film peels off at a high temperature. Another reason is that in a car navigation system that does not require pen touch input, the necessity of increasing the strength of the touch film is low.

  Next, an embodiment of a display device with a touch panel according to the present invention will be described with reference to FIGS.

  FIG. 1 is a front view of a display device with a touch panel in which the touch panel 2 and the frame 28 are assembled. The touch panel 2 is accompanied by a display device, and a screen is displayed on the display device by application software and control means of the device. On the left side of the display unit of the touch panel 2, a button for closing the application window and a slider button E for scrolling the window display area are displayed. These buttons E are display units that can be operated by touch input with a pen. At the same time, a rectangular obstruction bar F is displayed so as to cover these buttons E. Here, in order to make the button E easy to understand, the obstruction bar F is displayed in a transparent color. However, it is better that the obstruction bar is actually shielded so that the button E cannot be seen.

  FIG. 1 shows that the button E is displayed on the touch panel 2 in an area at a distance C from the outer wall of the touch panel 2 which is an operation non-guaranteed area for touch pen input shown in FIG. Here, if the window display unit including the button E is moved to the position shown in FIG. 1 by dragging by the pen operation by the user, and the moving operation is terminated at that time, the window display unit moves in the direction of arrow G in FIG. The display of the panel is automatically controlled so that the whole is moved. This movement is preferably performed up to a position where the button E is displayed outside the operation non-guaranteed area.

  The operation non-guaranteed area is an area defined in the touch panel 2 that is used for car navigation that is not supposed to be operated by pen touch input. For example, when a pen touch input is made at a position indicated by an arrow A in FIG. 2, the portion indicated by B is highly likely to be damaged, and an operation non-guaranteed area is set. That is, the display device with a touch panel according to the present invention controls the button E not to be displayed when the button E that requires pen touch input is displayed in the operation non-guaranteed area, or the operation non-guaranteed area. The feature is that the button E displayed on the screen cannot be touched with a touch pen.

  Control that is not displayed or means that cannot be touched can be realized by a combination of software processing means and hardware means, or one of those means.

  Next, an embodiment of a display device with a touch panel according to the present invention will be described in detail with reference to FIG. FIG. 3 is a block diagram showing the configuration of the display device with a touch panel according to the present invention. The display device with a touch panel has the same basic structure as the information processing device having the display unit 2 with a touch panel. That is, it comprises a hard disk drive that stores software, a RAM that develops the read software, and a CPU that processes the software. Various controls are exhibited by the CPU executing corresponding software.

  The operation button monitoring means 41, the obstruction area display means 42, and the operation button display area pull-back means 43, which are the features of the present invention shown in FIG. 3, are one of the control means realized by the linkage of software and CPU.

  The operation button monitoring unit 41 is a unit that monitors whether or not the operation button E included in the application window is displayed in the operation non-guaranteed area. Preferably, when the operation button monitoring unit 41 determines that the operation button E is displayed in the operation non-guaranteed area in the disturbance monitoring resident application, the operation button monitoring unit 41 sends a corresponding instruction signal to the disturbance display unit 42. In addition, when the operation button E goes out of the operation non-guaranteed area, the operation button monitoring unit 41 sends an instruction signal corresponding to the operation button E to the disturbance display unit 42.

  For example, when the application window is displayed in full screen, the operation button E is displayed in the operation non-guaranteed area. Therefore, if the instruction for full screen display is recognized, the operation button monitoring unit 41 sets the operation button E to Therefore, it can be determined that it is displayed in the non-guaranteed area. In this case, since the operating system grasps the full screen display, the operation button monitoring means 41 only needs to obtain the information and send an instruction signal for displaying the disturbance area to the disturbance display means 42.

  Further, the operation button monitoring means 41 is moved when the operation button E included in the application window is displayed in the operation non-guaranteed area by dragging by the user's stylus pen operation, and dragging is stopped at that time. A corresponding instruction signal is sent to the operation button display area pulling means 43.

  The disturbing area display means 42 receives the instruction signal corresponding to the operation non-guaranteed area display of the operation button E from the operation button monitoring means 41 and blocks the operation button E so that the operation button E cannot be operated. The disturbing area F is displayed. This is because, when the user performs a pen touch input on the operation button E displayed in the operation non-guaranteed area of the touch panel 2, the portion shown in FIG. 2B is likely to be damaged, so that the user can avoid the operation. It is. Therefore, it is only necessary to display a disturbing area that allows the user to avoid operating the operation button E without shielding. At the same time as the display of the disturbing area F, a display may be performed to inform the user that the operation button E cannot be operated.

  The interference area display means 42 receives the instruction signal corresponding to the operation non-guaranteed area display of the operation button E from the operation button monitoring means 41, and cancels the display of the interference area F. Similarly, when a display is displayed to inform the user that the operation button E cannot be operated, this display is also canceled.

  When receiving the corresponding instruction signal from the operation button monitoring unit 41, the operation button display area pull-back unit 43 redisplays the entire application window so that the operation button E is displayed outside the operation non-guaranteed area. The purpose is to improve user convenience.

Finally, referring to FIG. 1 and FIG. 2, another embodiment of the touch panel type display panel according to the present invention will be described. The embodiment described here is characterized in that the button E displayed in the non-operation guaranteed area cannot be touch-operated by hardware means. 2 shown in FIG. 2 is a frame surrounding the outer edge of the touch panel.
The frame 28 includes a non-transparent portion 28a and a transparent portion 28b. The frame 28 is, for example, an integrally molded product made of a transparent plastic material, and the non-transparent portion 28a is colored. The frame 28 may be formed by integrally molding a transparent plastic material and a colored plastic material, or may be configured by combining separately molded parts.

  The non-transparent portion 28a is configured to cover the portion where the resist 25 shown in FIG. 2 is provided, and the transparent portion 28b is configured to cover an area that can be displayed on the display panel and an operation non-guaranteed area. The That is, even when the button E shown in FIG. 1 is displayed in the operation non-guaranteed area, the user can visually recognize the button E through the transparent portion 28b, but cannot perform the pen touch operation. As a result, pen touch input in the non-operation guaranteed area can be prevented, so that it is possible to prevent damage to the portion B shown in FIG.

  Further, since the screen display area can be visually recognized by the transparent portion 28b as much as possible, the use when the pen touch input is not performed is not limited.

  As described above, by providing a means for preventing the user from touching the periphery of the touch panel that is weak in mechanical resistance due to touch input, damage to the periphery of the touch panel having low mechanical resistance can be prevented. It is possible to provide a touch panel type display device that can be switched between a navigation system and a personal computer.
