TECHNICAL FIELD OF THE INVENTION
The present invention relates to a liquid crystal operation panel used for a bank terminal such as an automatic teller machine (ATM, CD), an automatic ticket vending machine, a vending machine, and the like, and particularly to a touch-type push button (hereinafter referred to as a touch button) displayed on a liquid crystal panel. (Hereinafter abbreviated as ")" to a three-dimensional display type operation panel in which the operation state of the touch buttons is displayed in a three-dimensional manner.
[0002]
[Prior art]
Conventionally, a touch button is displayed on an operation panel, and when the button is operated (touched) with a finger, a touch panel is used as a liquid crystal operation panel that changes the display that is operated as if the push button was pressed down mechanically. There has been a configuration in which a shadow is provided around a button to make it look three-dimensional, and the shadow is changed according to an operation on the touch button. (For example, refer to Patent Document 1.)
FIG. 9 shows the touch buttons of the conventional liquid crystal operation panel disclosed in Patent Document 1 described above. In order to display a plurality of touch buttons 12 on the liquid crystal panel and to provide a pseudo three-dimensional display, each touch button 12 has It is configured to be displayed with a shadow 13. The liquid crystal panel is displayed in the area of the opening 11 provided in the protective cover 10 such as an acrylic plate or glass, and is configured to detect an operation (touch) of a touch button by a touch sensor (not shown). The twelve shadows 13 are displayed shorter than the shadows 13 of the other touch buttons 12 to display as if the operated touch button was pressed, so that the operator can easily recognize the operation state.
[0003]
On the other hand, conventionally, a stereoscopic image display apparatus called a “parallax barrier method” utilizing the difference in the appearance of the left and right eyes, that is, the characteristic of the human eye that senses a stereoscopic image from binocular parallax, has been known. (For example, see Patent Document 2). This stereoscopic video display device can observe a stereoscopic video without using special glasses.
[0004]
FIG. 10 is a conceptual diagram illustrating the principle of the parallax barrier type stereoscopic image display device disclosed in Patent Document 2. The three-dimensional image display device includes an image panel 27 such as a liquid crystal display panel disposed above a backlight 30 and a light shielding barrier 40 disposed above the image panel 27. The right-eye pixels 28 and the left-eye pixels 29 are alternately displayed on the image panel 27, and the observer can see through the pores (openings) 42 formed in the light-shielding barrier 40 (generally called a parallax barrier). By observing the right-eye pixel 28 with the right eye 25 and the left-eye pixel 29 with the left eye 26, it is possible to observe a stereoscopic image by the binocular parallax effect. The right-eye pixel 28 and the left-eye pixel 29 are image data obtained by photographing a subject with two cameras, for example.
[0005]
The pores formed in the light-shielding barrier 40 are formed at regular intervals at intervals P in the figure corresponding to the intervals between the pixels of the image panel 27. When the distance between the left and right eyes 25 and 26 is E, the distance from the both eyes to the light-shielding barrier 40 is A, and the distance between the light-shielding barrier 40 and the image panel 27 is D, the geometrical configuration is proportional expression A : E = D: B and proportional equation A: P = (A + D): 2B If the distance A and the interval P are selected so as to satisfy both equations, they are shown by lines 51 and 52 in the figure. As shown in the figure, the right-eye pixel 28 can be seen from the right eye 25 and the left-eye pixel 29 can be seen from the left eye 26 through the pores 42. Usually, a liquid crystal switch or the like capable of controlling the light shielding function of the light shielding unit is used for the light shielding barrier 40.

[Problems to be solved by the invention]
However, in the conventional method disclosed in Patent Document 1, a touch button displayed as a mere two-dimensional image is displayed with a shadow, so that the touch button is three-dimensionally observed by an illusion of a viewer. However, there is a problem that the difference between the appearance before the operation and the appearance at the time of the operation cannot be clearly recognized as when an actual mechanical push button (push button having a three-dimensional structure) is operated.
[0009]
The inventor of the present application has conducted various studies to solve the above problems, and as a result, applying the technology of the stereoscopic video display device, stereoscopically displaying the touch buttons, and displaying the operated touch buttons with the button. The present invention has been found that, by changing the display to a state in which is pressed, the stereoscopic effect of the operation panel becomes clearer and the difference before and after the operation of the operated touch button can be more clearly recognized. Is completed.
[0010]
That is, an object of the present invention is to solve the above-described problems, and to apply a stereoscopic image display technology to make the stereoscopic effect of the display of the operation panel clearer and to clearly recognize the operation state of the touch buttons. It is an object to provide a three-dimensional display type operation panel.
[0011]
[Means for Solving the Problems]
The above object of the present invention can be achieved by the following configurations. That is, the three-dimensional display type operation panel of the present invention includes a three-dimensional image display including an image panel for displaying touch buttons, a light blocking barrier for generating a binocular parallax effect, a backlight, a touch panel sensor, and the touch panel sensor. A control circuit for controlling the three-dimensional image display based on positional information from the camera, the control circuit including a function of partially controlling the light shielding of the light-shielding barrier, and a touch button for the three-dimensional image display. When displaying an image and detecting an operation on the touch button with the touch panel sensor, the button is pressed to display a stereoscopic image of the touch button operated by the control circuit based on position information from the touch panel sensor. It is characterized in that the display is changed to the displayed state.
[0012]
Further, the touch button is constituted by a plurality of buttons that can be operated by an operator, characterized in that the display corresponding to the operated touch button is partially controlled by the control circuit, The control circuit is characterized in that, when an operation on the touch button is detected, the control of the light shielding of the light shielding barrier is maintained in a state before the operation of the touch button.
[0013]
Further, when the control circuit senses an operation on the touch button, the control circuit controls light shielding of the light shielding barrier in a portion corresponding to the operated touch button, and approximates an image of the operated touch button. The display is changed to a planar display.
[0014]
Further, the display pixel of the touch button includes a three-dimensional display pixel and a two-dimensional display pixel, and when the control circuit detects an operation on the touch button, the control circuit corresponds to the operated touch button. Controlling the light-shielding of the light-shielding barrier in a portion to be operated, changing the image of the operated touch button to a flat display state, and changing the image to the flat display pixel.
[0015]
Further, when the control circuit detects that the operation on the button has been completed by the touch panel sensor, the control circuit returns the display of the operated touch button to a display state before the operation.
[0016]
According to the stereoscopic display type operation panel having such a configuration, by applying the technology of the stereoscopic video display device, a touch button is displayed in a stereoscopic video so that an observer sees the same as an actual mechanical push button, The display of the touch button operated by the operator is changed to a display in a state where the touch button is pressed, so that the operator can easily recognize the operated button.
[0017]
Further, according to the three-dimensional display type operation panel having such a configuration, it can be used for displaying a plurality of touch buttons, and further, the light-shielding control function of the light-shielding barrier at the operated touch button portion is maintained in a switch ON state. It is possible to change the display to a state in which the touch button is pressed only by changing the three-dimensional display pixels of the image panel.
[0018]
Further, by changing the light-shielding control function of the light-shielding barrier in the portion of the operated touch button to the switch OFF state without changing the stereoscopic display pixel of the image panel, the three-dimensional image pixel can be approximated. It can be easily displayed as a planar image (approximate two-dimensional image).
[0019]
In the operated touch button portion, the display of the image panel is changed from the stereoscopic display pixel to the planar display pixel under the control of the control circuit, and the light-shielding control function of the light-shielding barrier is changed to a switch OFF state. By doing so, it can be displayed as a planar image. In this case, since a pixel dedicated to flat display is used, the image of the touch button is clear, and there is no need to prepare two types of three-dimensional image pixels, so that the configuration can be simplified.
[0020]
Further, when the operation of the touch button by the operator is completed (the touch state is canceled), the stereoscopic display of the touch button returns to the display of the state before the operation, and the operator mistakes the plurality of touch buttons. It can be operated one after another without any trouble.
[0021]
Such a three-dimensional display type operation panel does not require special tools such as three-dimensional glasses, and is therefore used for an unspecified number of operators. Automatic teller machines at banks, ticket vending machines at stations (automatic ticket vending machines). In addition, the present invention can be suitably applied to other operation panels, and since only a light shielding barrier is interposed between the touch panel and the image panel, the product can be compactly manufactured.
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a stereoscopic display type operation panel as a first embodiment of the present invention will be described in detail with reference to the drawings.
[0023]
FIG. 1 is a conceptual diagram showing a perspective configuration of a stereoscopic display type operation panel according to a first embodiment of the present invention, FIG. 2 is a diagram showing a multilayer structure of a light-shielding barrier according to the first embodiment, and FIG. FIG. 4 is a block diagram showing the connection between the panel and the main circuit portion, FIG. 4 is a plan view showing a state before the touch operation of the numeral input area in the first embodiment, FIG. 5 is a flowchart showing the operation of the first embodiment, and FIG. FIG. 5 is a plan view illustrating a time of a touch operation on a number input area in one embodiment.
[0024]
In FIG. 1, a stereoscopic display type operation panel 100 is configured by stacking a backlight 140, an image panel 150 such as a liquid crystal display panel, and a stereoscopic video display 105 including a light shielding barrier 160, a touch panel sensor 170, and a protective cover 101. I have. The protective cover 101 is formed by laminating an aluminum plate on a transparent acrylic plate, and the aluminum plate is provided with openings 112, 122, and 132 at positions corresponding to portions where images are displayed. The protective cover 101 may be made of only a transparent material such as an acrylic plate. In this case, it is not necessary to provide the openings 112, 122, and 132.
[0025]
In the display areas 110, 120, and 130 corresponding to the openings 112, 122, and 132, an operation guide, an operation start button, and a touch button of the operation panel are displayed, though not limited thereto. For example, in the case of an automatic teller machine at a bank, the operation guide displays characters such as deposit, withdrawal, and transfer. This operation guide may be a form in which the transaction types are displayed in a list, or a form in which the transaction types are sequentially displayed by operating the operation start button. In the former case, the operation start button is not necessarily required. The touch buttons are buttons for inputting the amount of money in the selected transaction type, and display numerical buttons 0 to 9 and unit buttons such as 10,000 yen and 1,000 yen. In the case of an automatic ticket vending machine at a station, there is no operation guidance, and a button or a price button in which a station name and a price to a destination station are set is displayed.
[0026]
In this operation panel, a two-dimensional display and a three-dimensional display can be partially used. For example, it is possible to adopt a configuration in which the operation guide is displayed two-dimensionally using the pixels for two-dimensional display and the touch buttons are displayed three-dimensionally using the pixels for three-dimensional display. In this case, a configuration may be adopted in which the region of the light-shielding barrier corresponding to the portion to be displayed in a plane is always controlled to be in a transmission state (without providing the counter electrode).
[0027]
The backlight 140 is equivalent to that used in a normal liquid crystal display device, and the image panel 150 is equivalent to an image of a conventional liquid crystal display panel or the like, and corresponds to the size of a touch button. In addition, a stereoscopic display pixel or a planar display pixel of the touch button can be selectively and partially displayed on a predetermined portion.
[0028]
As shown in FIG. 2, the light-shielding barrier 160 includes two transparent polarizing plates 162 and 164, and a polarizing plane switching switch liquid crystal plate 166 sandwiched between the two polarizing plates. It is composed of a phase barrier plate 168 for a lax barrier, and is integrally fixed from the upper surface and the lower surface by transparent glass plates 161 and 169 for protection. The switch liquid crystal plate 166 switches the deflecting surface of the light from the polarizing plate 162 to “45-degree rotation” or “no rotation” by turning on and off the power. Further, a plurality of strip-shaped regions corresponding to the pores of the parallax barrier are formed at predetermined intervals on the phase difference plate 166 for parallax barrier, and the orientation of the regions and the intervals is 90 degrees. It is formed by curing in a state where polymer liquid crystals are arranged in different degrees.
[0029]
When light from below is indicated by the arrow in the figure, the light-shielding barrier 160 turns on and off the voltage applied to one of the pair of electrodes provided on the switch liquid crystal plate 166 to turn off the polarizing plate 164. From above, the spacing appears opaque or transparent. When it becomes opaque, the light shielding barrier 160 functions as a parallax barrier. Therefore, in the case where the stereoscopic image display is partially performed on the operation panel, the counter electrode may be formed so as to partially control ON and OFF of the voltage application. The voltage application to the counter electrode may be selectively turned on and off.
[0030]
The touch panel sensor 170 is composed of a plurality of horizontal lines made of the same transparent conductive resin and a corresponding plurality of vertical lines made of the same transparent conductive resin in a normal transparent resin layer. The position information of the corresponding portion due to the change in the capacitance between the horizontal line and the vertical line of the operated portion is sent to a touch panel sensor control circuit described later. Note that a touch panel sensor having another structure may be used.
[0031]
Next, the control circuit 190 of the stereoscopic display type operation panel 100 will be described. As shown in FIG. 3, each layer is connected to the power supply 180 and the control circuit 190. In the figure, a power supply 180 supplies power to the backlight 140, the main control circuit 191, and others. The control circuit 190 includes a main control circuit 191, an image panel driving circuit 195, a light-shielding barrier control circuit 196, and a touch panel sensor control circuit 197. The main control circuit 191 includes a central processing unit (CPU). The image panel drive circuit 195 and the light-shielding barrier control circuit 196 are controlled based on the program, similarly built-in image data, and information from each control circuit or drive circuit, and the stereoscopic image display 105 is operated via these circuits. It is configured as follows.
[0032]
The touch panel sensor control circuit 197 is connected between the main control circuit 191 and the touch panel sensor 170, and mainly stores the position information of the touch button operated by the operator touching with a finger and the position information of the touch button not operated. It is sent to the control circuit 191.
[0033]
The image panel drive circuit 195 is connected between the main control circuit 191 and the image panel 150, and performs control for displaying an image on the image panel 150 based on a control signal of the main control circuit 191.
[0034]
An image corresponding to the operation of the operator by a control signal of the main control circuit 191 based on the position information from the touch panel sensor 170, that is, a three-dimensional image in which the display pixel of the operated touch button is switched and the touch button is pressed. Display video. Specifically, the three-dimensional display pixels in which the apparent height of the image of the operated touch button is reduced are displayed, and the non-operated touch button is also in a state before being pressed, that is, a three-dimensional image of the height before being pressed. Display video. Therefore, in this embodiment, as the three-dimensional display pixels of a plurality of buttons constituting the touch button, a three-dimensional display pixel before pressing and a three-dimensional display pixel in a pressed state are prepared for each button. It will be displayed alternately.
[0035]
The light-shielding barrier control circuit 196 is connected between the main control circuit 191 and the light-shielding barrier 160, and controls ON and OFF of the switch liquid crystal panel 166 of the light-shielding barrier 160 based on a control signal of the main control circuit 191 (for a pair of electrodes). (Application of voltage to one side is controlled). That is, based on the control signal of the main control circuit 191, the portions of the switch liquid crystal plate 166 corresponding to the display areas 120 and 130 are maintained in a light-shielded state (voltage application to the opposing electrode is ON), and partially as a parallax barrier. It is configured to exhibit the function of.
[0036]
In other words, in the three-dimensional display type operation panel 100 of FIG. 1, the display area 110 is in a flat display state, and even if the operator touches the display of this area with a finger, the light shielding barrier in the three-dimensional image display 105 of this part 160 is simply kept in a transmissive state without any particular operation by the above configuration, and the display by the image panel 150 in this area is merely a two-dimensional display. This allows the operator to more clearly observe the stereoscopic display of the touch button portion.
[0037]
The display areas 120 and 130 are in a three-dimensional display state, and the switch liquid crystal panel 166 of the corresponding light-shielding barrier 160 is in a light-shielded state (voltage application to the opposing electrode is ON) under the control of the main control circuit 191 to perform three-dimensional display. It is configured to
[0038]
Next, the operation of the first embodiment of the present invention will be described with reference to the flowchart of FIG.
[0039]
The power supply 180 is turned on, and power is supplied to each part of the three-dimensional display type operation panel 100. As described above, the display area 110 is controlled to be in a flat display, and the display areas 120 and 130 are controlled to be in a three-dimensional display state. In the display area 130, as shown in FIG. 4, touch buttons including a plurality of buttons 135 for inputting numbers are displayed in a three-dimensional manner.
[0040]
In the flowchart of FIG. 5, first, when the operator operates the operation start button 125 (see FIG. 1) displayed in the display area 120 to input an operation start, the touch panel sensor 170 detects this, and The position information is sent to the touch panel sensor control circuit 197. As a result, the main control circuit 191 causes the display area 110 to display operation guidance necessary for the next operation via the image panel driving circuit 195, and the operator follows the guidance and presses the numeric input touch button 135 to press the next. Work can proceed.
[0041]
In step S101, all the touch buttons displayed in the display area 130 are displayed as stereoscopic images as shown in FIG. Next, in step S102, when the touch button 135 at the lower left corner is operated by the operator's finger, the touch panel sensor 170 detects the touched button (hereinafter, abbreviated as touched button) at the operated portion. Then, the position information of the button is sent to the main control circuit 191 via the touch panel sensor control circuit 197.
[0042]
In step S103, as a result, the main control circuit 191 displays a state corresponding to the above-mentioned touched button on the image panel 150 via the image panel driving circuit 195 according to a predetermined program, that is, Change the display height of the button to a lower state. As a result, the height of the three-dimensional image of the touched button is displayed as low as if pressed with a finger, as shown in FIG. 6, so that the operator can operate the mechanical push button ( It is possible to clearly recognize the touched button as if the user pressed a three-dimensional structure push button.
[0043]
In step S104, as long as the operated state continues, the height of the three-dimensional image display of the touched button remains low, the standby state for the next operation is maintained, and the operator releases the finger from the touched button ( When the operation is completed), the touch panel sensor 170 detects this, and sends this operation information to the main control circuit 191 via the touch panel sensor control circuit 197.
[0044]
As a result, in step S105, the main control circuit 191 returns the display of the touched button to the display state before the operation via the image panel driving circuit 195 according to a predetermined program, and returns to the standby state in step S102.
[0045]
Next, a three-dimensional display type operation panel according to a second embodiment of the present invention will be described. FIG. 7 is a flowchart showing the operation of the second embodiment of the present invention, and FIG. 8 is a plan view showing the state when operating the touch buttons in the second embodiment.
[0046]
The above-described first embodiment is configured to change the apparent height of the stereoscopic image display of the operated touch button, and the stereoscopic display pixels of the image panel 150 are operated and non-operated. Two kinds were prepared. In the second embodiment, the touch button image is configured by a combination of a three-dimensional display pixel and a two-dimensional display pixel, and the display of the operated button is changed to the two-dimensional display as a display in a pressed state. It is.
[0047]
The control circuit according to the second embodiment has the same configuration as the control circuit illustrated in FIG. 3 of the first embodiment, but controls the button portion when the touch button is operated from the stereoscopic display to the planar display. The difference is that switching and control are performed so as to display the flat display pixels. That is, the image corresponding to the button operated by the control signal of the main control circuit 191 based on the position information from the touch panel sensor 170 is switched to the pixel for flat display and displayed on the image panel 150. Further, a control signal of the main control circuit 191 based on the position information from the touch panel sensor 170 is configured to control a portion of the switch liquid crystal panel 166 corresponding to the operated button to change from a light-shielded state to a transparent state. I have.
[0048]
The operation will be described with reference to the flowchart of FIG. The operations in steps S201 and S202 of the flowchart in FIG. 7 are the same as those in the first embodiment.
[0049]
When the touch button (see FIG. 4) at the lower left corner is operated by the operator in step S203 as in the first embodiment, the main control circuit 191 causes the image panel driving circuit 195 to execute the operation according to a predetermined program. The partial image corresponding to the above-mentioned touched button in 150 is switched from the three-dimensional display pixel to the two-dimensional display pixel.
[0050]
In step S204, the main control circuit 191 switches the above-mentioned touched button portion of the switch liquid crystal panel 166 from the light-shielded state to the transparent state via the light-shielding barrier control circuit 196 according to a predetermined program. As soon as the button portion is touched, the display is switched from the three-dimensional display to the two-dimensional display, including its surroundings, as shown in FIG. 8, so that the operator is clearly covered as if he / she operated a mechanical push button. Recognize pressing of touch buttons.
[0051]
In step S <b> 205, the display of the touched button is maintained as a flat display, and the standby state for the next operation is maintained. Next, in step S206, when the operation of releasing the finger from the touched button is completed, the touch panel sensor 170 detects this and sends this position information to the main control circuit 191 via the touch panel sensor control circuit 197.
[0052]
As a result, the main control circuit 191 returns the planar image display of the portion corresponding to the touched button on the image panel 150 to the stereoscopic image display via the image panel driving circuit 195 according to a predetermined program. At the same time, the main control circuit 191 returns the corresponding portion of the switch liquid crystal panel 166 from the transmissive state to the light-shielded state via the light-shielding barrier control circuit 196 in accordance with a predetermined program to return to the stereoscopic display state, and returns to step S202. As a result, the touched button returns to the stereoscopic image display when the finger is released (the operation is completed), so that the operator can recognize as if he / she had released the finger from the mechanical push button.
[0053]
In the second embodiment, the display of the touched button on the image panel 150 is switched from the three-dimensional display pixel to the two-dimensional display pixel. However, when the quality of the display screen does not matter, only the three-dimensional display pixel is used. It is possible to prepare and display the operated button portion in a planar display. In this case, since the light-shielding barrier at that portion is controlled to a two-dimensional display state, even a three-dimensional display pixel is not observed as a three-dimensional image, but is observed as a pseudo two-dimensional image although image quality is reduced.
[0054]
Specifically, when the operated touch button is detected by the touch panel sensor 170, the parallax barrier of the light-shielding barrier 160 is transmitted through the parallax barrier of the light-shielding barrier 160 without changing the stereoscopic image pixels of the image panel 150 under the control of the control circuit 190 (see FIG. By changing to (switch OFF), the three-dimensional display pixel is displayed as an approximate plane image.
[0055]
【The invention's effect】
As described in detail above, according to the three-dimensional display operation panel of the present invention, the touch buttons are displayed in a three-dimensional image, and the display of the operated touch buttons is changed to a display in a state where the buttons are pressed. Therefore, the button operated in the same manner as the mechanical push button (three-dimensional structure push button) can be clearly recognized.
[0056]
In addition, if the display of the operated button is performed by switching from the stereoscopic display to the planar display, it can be configured more easily than switching the stereoscopic display pixels, and a light shielding barrier is interposed between the touch panel and the image panel. Therefore, the entire operation panel can be made compact.
