[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel display device, which is mounted as an operation panel device on a control device or other device, and the control device or the like is touched by an operator or an operation finger of an operation machine. To an improvement in a touch panel display device for externally operating a device.

[0002]

2. Description of the Related Art Conventionally, as a touch panel display device of this type, as shown in FIG. 15, for example, a main control unit 1 is connected to an image display unit 5 such as a liquid crystal display or a plasma display via a display control unit 3. A touch panel unit 7 having a good transparency and having a large number of switch elements (omitted in FIG. 15) that are turned on by an external touch in a matrix is superimposed on the image display surface of the image display unit 5, and the touch panel unit 7 is switched. A configuration in which the switch detection unit 9 is connected to the main control unit 1 while being connected to the detection unit 9 is known. That is, the display control unit 3 controls the layout of the display image on the image display unit 5 based on the operation image data output from the main control unit 1, and switches signals from individual switch elements of the touch panel unit 7 to the switch detection unit 9. The main control unit 1 detects the position of the touch panel unit 7 that has been switched on from the outside and identifies the image display area corresponding to the switched on position. The main control unit 1 determines whether any operation is externally input.

Accordingly, as shown in FIG. 16, for example, the operator operates an image display 15 of the image display unit 5 arranged on the operation surface side of the main body case 13 of the control device 11, that is, a ten-key display 15a, and an arrow key for moving a cursor. While viewing the display 15b, the table display 15c, the function key display 15d, the shift key display 15e, etc., by touching those display areas of the touch panel unit (transparent and invisible in FIG. 16) 7 with a finger or a pen or the like, The number of inputs and operation inputs corresponding to the touch area can be made. In particular, for example, eight types of key images F1 to F8 are displayed as the function key display 15d, and the shift key display 15d is displayed.
e and one of the function keys 15d (F1 to
When F8) is pressed, the function key display 15d (F1
There are many configurations in which the functions of F8 to F8 can be changed and 16 types of functions can be selected.

[0004] By the way, the touch panel unit 7 described above
For example, as shown in FIG.
9, a flexible sheet 21 formed in an interdigital shape on one side,
23 and the electrodes 17, 1 with a spacer 25 interposed therebetween.
9 are overlapped in a state of being orthogonal to each other, and are formed so as to have transparency as a whole. Then, by touching a finger or the like from one side of the touch panel section 7, the opposing electrodes 17, 1
9 are brought into contact with each other to perform an on-operation, and opposing electrodes 17 and 19 form individual switch elements 27. However, the image display area, that is, the individual numeric key areas (switch areas) of the numeric keypad display 15a and the arrow key display 15 are formed by the plurality of adjacent switch elements 27.
b, each arrow key area (switch area), and each function key area F of the function key display 15d
1 to F8 (switch area) and a shift key area (switch area) of the shift key display 15e are formed.

[0005]

However, in the above-mentioned touch panel display device, the operator needs to use the ten-key display.
5a, arrow key display 15b, function key display 1
5d, when touching the shift key display 15e, etc., it is necessary to accurately touch those key display areas in order to perform a desired number input or operation input. If the wrong key display area is touched, an incorrect number input or operation input will be made, and it will be necessary to return to the original setting display image and operate again to make an accurate number input or operation input again. It is troublesome.

[0006] However, if the operator, for example, arrow key display 1
When 5b is touched, touched arrow key display 15b
A touch panel display device has been proposed in which the operation can be confirmed by changing the display state by changing or inverting the overall color. Just know the number input and operation input,
There was also a drawback in that similarly troublesome operations were required to re-enter the correct numbers and execute the operations. Further, in the touch panel display device, when a plurality of key display areas are touched by mistake due to parallax or the like, it is important that one target key display area can be easily selected.

[0007] For example, when contradictory function key display areas such as selection of a previous page and selection of a subsequent page are adjacent to each other, the key display area pressed first by accident is not effective but selected by the operator. There was a desire for a configuration that encouraged
Further, in the conventional touch panel display device, when a plurality of key display areas are touched, there are many configurations in which the previously pressed key display area is effective. For example, it is possible to easily overlap the function key display 15d and the shift key display 15e. A configuration that can be used has been desired.

In particular, in order to perform the overlapping input, both hands or one hand must be touched by using a plurality of fingers, and a configuration which can be operated at once by one hand has been desired. The present invention has been made in order to solve such a conventional drawback, and when touching a touch panel unit, it is possible to give an operator an opportunity to confirm, so that a desired operation can be performed easily and accurately. It is intended to provide a touch panel display device. Another object of the present invention is to provide a touch panel display device capable of alternately determining any one of the specific image display areas even when the user touches a plurality of image display areas simultaneously. Still another object of the present invention is to provide a touch panel display device capable of determining a plurality of image display areas touched simultaneously at the same time.

[0009]

According to the present invention, there is provided an image display unit having an optical image display surface, and display control for controlling image display of the image display unit based on image data. Unit, a touch panel unit having switch elements that are turned on or off by an external touch in a matrix and superimposed on an image display surface of the image display unit so that a display image can be seen through, and the switch elements that are touch-operated , A region determination unit that outputs a detection signal from at least the switch detection unit, and outputs image data to the display control unit and responds based on the detection signal from the region determination unit. and outputs the image data to be sequentially enlarged <br/> change the display state of the image display area where switching element belongs are and a main control unit. Moreover, in the present invention, when a change in the image display area in which the display is enlarged on the touch panel section has passed for a certain period of time, the image display area is determined as an image display area that has been touched from the outside, and a determination signal is sent to the main control section. The area determination section is formed so as to output, and the main control section is formed so as to determine which image display area has been operated from the outside based on the determination signal.

[0010] The present invention also relates to an adjacency which cannot be determined at once.
When the image display area whose display state changes corresponds to the inappropriate combination data, the switch that has been turned on or off from outside during a certain period
It is preferable that the area determining section is formed so that the image display area having more switch elements is alternatively determined as the determined image display area and the determination signal is output. Further, the present invention has matching combination data of adjacent image display areas that can be determined at once, and when the image display area whose display state is enlarged and changed corresponds to the matched combination data, those whose display state is enlarged and changed. it is also possible to form the region determination unit to output the determined by determination signal at a time by an image display area and placing the image display area.

[0011]

According to the present invention having such means, when a switch element on the touch panel is touched, the switch detector detects the touched switch element, and the area determination section sends the detection signal to the main controller. The main control unit outputs image data for sequentially expanding and changing the display state of the image display region to which the switch element corresponding to the detection signal from the region determination unit belongs to the image display unit via the display control unit, The display state of the image display area on the touch panel unit is sequentially enlarged . When the change of the image display area in which the display is enlarged has passed for a predetermined period, the area determination section determines the image display area that has been touch-operated from the outside and outputs a determination signal to the main control section. The control unit determines which image display area has been operated from the outside.

Further, the area determination section has unsuitable combination data of adjacent image display areas that cannot be determined at one time, and when a plurality of touched image display areas correspond to the unsuitable combination data, the area determination section receives an external combination during a predetermined period. On or off
In the configuration in which the image display area with the larger number of switch elements operated is selectively determined as the confirmed image display area, if the plurality of touched image display areas are the unsuitable combination areas, the image display area is not displayed during a certain period. touch operation from the outside to the Saretasu
Only the image display area with more switch elements is automatically determined. Further, the area determination section can determine at once
In the configuration having the matching combination data of the adjacent image display areas and the image display area whose display state is enlarged and changed to be determined as the determined image display area, a plurality of touched image display areas have elapsed for a certain period of time. Later automatically and at once confirmed.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a touch panel display device according to the present invention. In FIG. 1, the main control unit 2
9 is a display control unit 3 for displaying a plurality of other image data for operation.
1, which will be described later in detail. The display control unit 31 is connected to an image display unit 35 which is a known image display unit having an optical image display surface such as a liquid crystal display, a plasma display, or a CRT display. The image layout of the image display unit 35 is controlled based on the image data for use. On the image display surface of the image display unit 35, a touch panel unit 37 is superimposed directly or at some interval.

The touch panel section 37 has a configuration as shown in FIG. 17 described above, has a plurality of switch elements 27 that are turned on by an external touch, in a matrix, so that the display surface of the image display section 35 can be seen. It is formed in a transmission state. For example, as shown in FIG.
A switch area SW1 is formed by the switch elements 27 (reference numerals in FIG. 2), and this is placed on the image display area 45 of reference numeral “A” on the image display surface of the image display unit 35 (omitted in FIG. 2). The corresponding arrangement is made so as to overlap. In the following description, the above-mentioned reference numeral 27 is used as a switch element. Touch panel unit 3
Each of the switch elements 27 can be formed so that the switch is turned off by an external touch.

Each switch element 27 of the touch panel 37
Is connected to the switch detection unit 39. In practice, each electrode (see FIG. 17) forming each switch element 27
7 and 19 extend from the end of the touch panel 37 and are connected to the switch detector 39. Switch detection unit 39
Detects the position of which switch element 27 is turned on based on the conduction state of the electrodes 17 and 19, and outputs a detection signal to the area determination unit 41.

For example, as shown in FIG.
When the lower right part of 5 is touched with the fingertip 43, the switch element in the switch area SW1 is turned on, and the switch detector 39 detects this on-switch element. Even if the image display area 45 is touched with the fingertip 43, it goes without saying that the corresponding area in the touch panel 37 is actually touched.

The area determination section 41 outputs a detection signal from the switch detection section 39 to the main control section 29 and has a function described later. The main control unit 29 includes the area determination unit 4
The image display area 45 to which the on-switch element corresponding to the detection signal belongs is determined on the basis of the detection signal from 1 and the operation image data, and the switch element adjacent to the on-switch element in the image display area 45 is centered. In addition to having a function of outputting image data to be changed and displayed differently from the initial state to the display control unit 31, such as sequentially lighting, blinking or inverting and displaying another color of the element images corresponding to
It has a function of determining which image display area has been externally operated based on a later-described determination signal from the area determination unit 41. That is, as shown in FIG. 4, when the lower right portion of the image display area 45 is continuously touched with the fingertip 43, the switch element in the switch area SW1 in FIG. 3 is turned on, and the main control unit 29 displays the image display to which the switch element belongs. The area 45 is determined, and image data for lighting the element image corresponding to the ON switch element is output to the display control unit 31 (FIG. 4A).

Then, the element image corresponding to the switch element adjacent to the ON switch element is turned on at a slight timing (FIG. 4B), and the image display area 45 is formed after a certain period (for example, one second) has elapsed. The image data for turning on all the element images corresponding to the switch elements 1 to 3 are output to the display control unit 31 (FIG. 4C). In FIG. 4, reference numeral 47 denotes a lighting area, which is indicated by a hatched portion. In the drawings described below, the hatched portion is a lighting region. In addition, the area determination section 41 is an image display area 45 that changes the display on the touch panel section 37.
Of the image display area 45 when the change of
Is determined to be an image display area touched from the outside, and a determination signal is output to the main control unit 29.

The main control unit 29 determines whether the image display area 45 has been touch-operated from the outside based on the determination signal.
An operation function corresponding to the image display area 45 is executed.
In the embodiment according to the present invention, when the touch panel display device configured as described above keeps touching the lower right portion of the image display area 45 on the touch panel unit 37 with the fingertip 43 as shown in FIG. Starts lighting from the element image corresponding to the switch element in FIG. 3 via the display control unit 31 and forms an image display area 45 after a certain period of time elapses after lighting the element image corresponding to the adjacent switch element. Since all of the element images corresponding to the switch elements are turned on, the lighting area in the touched key area is sequentially enlarged and changed, so that the operator can easily confirm the touched key area.

When the display change state of the image display area 45 has passed for a certain period, the area determination section 41 determines that the image display area 45 is an image display area that has been touch-operated from the outside, and the main control section 29 When the key area is touched, the operation process is not immediately executed even if the key area is touched, and it is possible for the operator to confirm the key area being operated before confirming it. By leaving the fingertip 43 away from the touch panel unit 37 and touching another image display area, re-input becomes possible, and the operability of the touch panel display device is improved. Moreover, since the light is turned on from the element image corresponding to the switch element touch-operated with the fingertip 43, if the touch position of the touched image display area 45 is shifted from the center, the light is partially turned on from the shifted position. Since the lighting is sequentially enlarged, there is an advantage that the operator can easily confirm the touch position.

It should be noted that even if the touch position of the image display area 45 is shifted from the center, the image display area 45 can be formed so that it is always lit from the center and sequentially enlarged and lit. Further, the above-mentioned fixed period may be a period from the time when the image display area 45 is partially turned on to the time when it is entirely turned on, or may be set arbitrarily. Such a configuration is the first embodiment according to the touch panel display device of the present invention, but the present invention can also have the following second and third embodiment configurations. FIG. 5 is a diagram for explaining a second embodiment of the touch panel display device of the present invention, and the block circuit configuration is the same as that of FIG.

In the second embodiment, the above-described area determination section 41 shown in FIG. 1 previously stores and stores improper combination data, which is a combination of adjacent image display areas 45 and 49 that cannot be determined at once. When the image display areas 45 and 49 are touched in the unit 37, it is determined whether or not the image display areas 45 and 49 correspond to the unsuitable combination data. The selected image display area 45 or 49 is selectively determined as a determined image display area, and has a function of outputting a determination signal to the main control unit 29. That is, as shown in FIG. 6, for example, the area determination unit 41 incorrectly combines the image display area 45 with the code “A” as the previous page selection key and the image display area 49 with the code “B” as the rear page selection key. Data is stored in advance, and the touch panel 37
When these image display areas 45 and 49 are touched, the main control unit 29 outputs image data for sequentially enlarging and changing the display of each of the switch elements to corresponding to the image display areas 45 and 49.

The image display area 4 of the unsuitable combination
When the portions 5 and 49 are touched, the area determination section 41 determines whether or not they correspond to the unsuitable combination data. For example, from the detection signal obtained via the switch detection section 39 during the above-described fixed period, for example, ON-operated switch element ~
The main control unit 29 has a function of alternatively determining one having a larger number as the determined image display area and outputting a determination signal to the main control unit 29. Therefore, as shown in FIG. 6, when the operator touches the boundary between the image display areas 45 and 49 of the unsuitable combination by mistake, FIG.
As shown by A to C, the light is turned on from the lower right part of the image display area 45 and the lower left part of the image display area 49, and the lighting range is sequentially enlarged and the whole is turned on. Reference numerals 51 and 53 are lighting areas.

Therefore, as shown in FIG. 7D, if the number of switch elements to be turned on by shifting the fingertip 43 toward the image display area 45 is increased, the lighting area of the image display area 49 is eliminated or reduced. As shown in F,
The lighting range is sequentially enlarged from the lower right of the image display area 45, and the entire area is lit. After a certain period of time, the area determination section 41 selectively determines the image display area 45 by a majority function, and the main control section 29 It recognizes the operation input to the display area 45 and executes the corresponding operation. 5 and FIG.
W1 and SW2 are switch areas corresponding to the image display areas 45 and 49.

As described above, in the second embodiment, in addition to the effects of the first embodiment, if the unsuitable combination data is stored in advance in the area determination section 41, the touch panel section 37
Even if the touch operation is performed on the adjacent image display area portions corresponding to a combination that cannot be determined at a time from the
If you increase the number of switch elements that are turned on, for example, by shifting the position, the image display area can be automatically determined with one hand, so even if you accidentally touch multiple adjacent image display areas together, the touch operation will change There is an advantage that the target image display area can be easily determined simply by performing the operation. Moreover, even if a plurality of adjacent image display areas are touched together, the target image display area can be easily determined, so that the plurality of image display areas can be packed and arranged, and the image display surface can be used effectively.

In the second embodiment, the operation for determining the image display areas 45 and 49 is performed by using the majority function by shifting the fingertip 43 or the like as described above. The external touch operation may be changed, such as counting the number of times the corresponding part is touched. 8 to 10 are views for explaining a third embodiment according to the touch panel display device of the present invention.

In the third embodiment, the above-described area determination section 41 of FIG. 1 is a combination of adjacent image display areas 45, 49, 55, and 57 that can be determined at a time, as shown in FIG. The compatible combination data is stored in advance, and when the image display areas 45, 49, 55, and 57 of the compatible association are input by touching the touch panel unit 37 with the fingertip 43, the image display areas 45, 49, and 55,
It is determined whether or not 57 corresponds to the matching union data.
It has a function of determining all of 55 and 57 as the determined image display area and outputting a determination signal to the main control unit 29. That is, when the area determination section 41 touches the image display areas 45, 49, 55, and 57 of the touch panel section 37 with the fingertip 43, the main control section 29 corresponds to the image display areas 45, 49, 55, and 57. Has a function of outputting image data for sequentially enlarging and changing the display of each of the switch elements 27 to.

Further, the area determination section 41 determines whether or not the touched image display areas 45, 49, 55, and 57 correspond to the matching combination data. It has a function of determining the image display area collectively and outputting a determination signal to the main control unit 29. Therefore, as shown in FIG. 9, when the user touches the boundary between the image display areas 45 and 55 on the touch panel unit 37, the light is turned on from the boundary between the image display areas 45 and 55, and the lighting range is sequentially enlarged and the image display area 45 is enlarged. , 55 are lit.

As shown in FIG. 10, when the user touches the boundary between the image display areas 45, 49, 55, and 57, the light is turned on from the boundary between the image display areas 45, 49, 55, and 57, and sequentially turns outward. The lighting range is enlarged and the image display area 4
5, 49, 55, and 57 are all turned on. Note that the round broken line in FIG.
Although there are switch areas corresponding to 5, 49, 55, and 57, they are not shown for convenience. As described above, in the third embodiment, in addition to the effects of the above-described first embodiment, if the matching combination data is stored in advance, a plurality of image display areas 4 can be stored together.
Touching 5, 49, 55, 57 has the advantage that the plurality of image display areas 45, 49, 55, 57 can be automatically determined.

In particular, if the image display areas 45, 49, 55, and 57 that need to be determined together are arranged close to each other, the plurality of image display areas can be determined at once with one fingertip 43. For example, as shown in FIG.
In the control device 59 similar to the above, if the image display 63 is such that the elongated shift key display 61e is closely arranged along the horizontally long function key display 61d, the function key display 61d (F1 to F8) and the shift key display 61e are touched by a fingertip (FIG. If not touched simultaneously at 43 (reference numeral a in FIG. 11), the function key display 61d
The functions (F1 to F8) can be changed. Reference numeral 63 denotes an image display unit, and reference numeral 65 denotes a main body case.
