Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel integrated with a display unit, and more particularly to display control on the display unit according to an input on the touch panel.

[0002]

2. Description of the Related Art Conventionally, a touch panel integrated with a display unit has been used in various fields such as a cash dispenser of a bank, information processing and process control. Since this type of device has not only an input function but also an output function, the installation space can be saved, and the guidance display for input can be displayed, so that even an unfamiliar person can easily handle it. .

[0003]

However, if a large number of touch areas for selection input are set, the individual areas become narrower, the input accuracy of the touch panel cannot be applied, and the resolution of the display section is limited. Since the display is small and hard to see, I could not set too many areas. Therefore, even if one is selected from many selection items, the whole image of the input screen cannot be grasped, which makes the user uneasy. In addition, in order to shift to a screen having a desired touch area, the panel must be touched many times. However, there is a problem that the operability is poor.

The present invention has been made in order to solve the above problems, and is for a touch panel integrated with a display unit, which enables setting of many touch input areas in a limited display space. The purpose is to provide a control method.

[0005]

In order to achieve the above object, the present invention provides a method of controlling a touch panel integrated with a display unit, wherein when a point on the touch panel is touched, the coordinates on the touched panel are coordinated. To determine whether the coordinates are inside any of the predetermined touch areas, and if it is determined that the coordinates are not inside any of the touch areas, a predetermined range from the touched point Check if there is a region to be touched within, and if there is a region to touch within the range, expand the range including all the regions to be touched within the range and display it in the window I did it.

Further, in the control method of the touch panel integrated with the display unit, when one point on the touch panel is touched, the coordinates on the touched panel are acquired and the coordinates of the predetermined area to be touched are acquired. If it is judged that it is inside any of the areas, and if it is judged that it is not in any of the areas, the positions of all the points touched within a predetermined time are stored, and the point touched first is stored. The range including all touched points within a predetermined time is enlarged and displayed in the window.

[0007]

With this control method of the touch panel configured as described above, many touch areas can be set on the touch panel.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a functional block diagram of a touch panel showing an embodiment of the present invention. In this figure, the touch panel 1 is a coordinate input device provided on the front surface of the display unit 6 and having transparent electrodes. Touch panel interface 2
Detects that the touch panel is pressed with a fingertip or the like, and also informs the coordinate input unit 3 of which position has been pressed. Further, the coordinate input unit 3 outputs the specific coordinates to the coordinate determination unit 4.

On the other hand, the display unit 6 periodically receives the bitmap data from the frame memory 7 and displays it on the screen. The contents of the frame memory 7 are asynchronously rewritten by the window control unit 8, and the result is reflected on the screen display of the display unit 6. The window control unit 8 receives the initial setting command from the application program 10, refers to the guidance data 11, and writes the pattern for the guidance display in the frame memory 7 and simultaneously creates the area data 5. Guidance data 11
In addition to the display pattern on the display unit, holds the position information of the area to be touched on a screen-by-screen basis. The window control unit 8 independently creates the position information of the area to be touched as the area data 5 and holds it in a form that the coordinate determination unit 4 can easily refer to.

The window control unit 8 sets an arbitrary window on the display screen of the display unit 6, writes the pattern currently displayed in the set window to the save memory 9, and displays the screen in the set window. It is possible to write an enlarged pattern. By this operation, the position of the area on the panel to be touched changes, so the position information of the corresponding area of the area data 5 is updated. FIG. 2 shows an example of the area data 5. The area data 5 holds the coordinates on the touch panel of each area for each touch screen, and the area type indicates the shape of the area, 1 is a rectangular area and 2 is a circular area. The following coordinates 1 and 2 represent the coordinates of two diagonal points in the type 1 rectangular area, and hold the center coordinates and radius in the case of the type 2 circular area. These are, when the application program 10 is started,
It is obtained by copying from the guidance data 11. Two sets of this coordinate data are held, and when a part of the screen is enlarged, the coordinate at the time of enlargement is held on the other side. In addition to the data related to this area, the guidance data 11 stores a pattern to be displayed on the display unit 6 or a character code indicating the meaning of the area.

The coordinate determination unit 4 detects the touch by the touch panel interface 2 and the touched coordinate sent via the coordinate input unit 3 is located in which region by referring to the previous region data 5. It is determined whether or not it is reported to the window control unit 8. Window control unit 8
If the coordinate determination unit determines that it is within a specific area,
The area number is passed to the application program 10, but if it is determined that the area number is not in any area,
As will be described later, a predetermined area is enlarged and displayed so that the area is touched correctly, waiting for a touch input, and data is sent to the application program 10 when the area is correctly touched.

Next, the operation of the touch panel integrated with the display unit constructed as described above will be described with reference to FIGS. 3 and 4. Wait for the touch panel to be touched (S0
1) If it is touched, it is determined whether or not it is inside any area to be touched (S02), and if it is within the area, a predetermined process is performed (S03). If it is not in any of the areas, it is checked whether or not there is an area to be touched within the predetermined range (S04), and if there is an area to be touched within the predetermined range, it is within the predetermined range. A range including all areas is set and enlarged, and a window is displayed (S05). If not, it is checked whether the window is set (S06), and if not set, the first step (S0)
Return to 1), and if set, close the window and restore the display. FIG. 4 shows a change in the display unit due to the above operation. When the position X is touched in FIG.
Although there is no area to be touched at this position, but there is an area in the vicinity, the area is enlarged and displayed in the window as shown in FIG. It should be noted that this window alone is not the target of the touch operation, and it is possible to return to the original screen by touching a portion outside the window. If any area outside the window is touched, the data may be processed as valid data instead of closing the window and returning the display.

FIG. 5 is a flow chart for explaining the operation of another embodiment. Wait for touch panel to be touched (S1
1) If touched, it is determined whether or not it is inside one of the areas to be touched (S12), and if it is within the area, a predetermined process is performed (S13). If it is outside the area, the touch input within the predetermined time is accepted (S14). If the number of touches is less than 2, the process returns to the first step (S11), and if it is 2 or more, a rectangular area including the touched point is set. Then, the window is enlarged and displayed. FIG. 6 shows a change in the display section due to the above operation. In FIG. 6A, X is the first touched position. Since there is no area to be touched at this position, if a + position is touched within a predetermined time, a rectangular area including two points is enlarged and displayed as shown in (b).

[0014]

As described above, in the control method of the touch panel integrated with the display unit according to the present invention,
Even if the area to be touched is close, by touching a position that does not enter any area, the surrounding area is enlarged, and any area specified by the operator can be enlarged, so many areas are displayed on the screen. The area can be set to improve operability. In addition, screen patterns and area data for guidance display can be created separately from the application program, and it is possible to determine whether it is in any area on the touch panel side and display the enlarged screen. There is also an effect that it becomes easy to create an application program.
