触摸式面板及其制造方法、使用该触摸式面板的输入装置Touch panel, manufacturing method thereof, and input device using the touch panel

技术领域technical field

本发明涉及用于各种电子设备操作的触摸式面板及其制造方法、以及使用有该触摸式面板的输入装置。The present invention relates to a touch panel used for operating various electronic devices, a manufacturing method thereof, and an input device using the touch panel.

背景技术Background technique

近年来，伴随手机及汽车导航系统等各种电子设备的高性能化及多样化，正在使用具有安装于液晶等显示元件前面的透光性触摸式面板的输入装置。操作者一边通过该触摸式面板视认背面的显示元件的显示，一边用手指或笔等按压操作触摸式面板，由此，进行设备中各功能的切换。作为这种触摸式面板，要求视认性优良且廉价。In recent years, with the high performance and diversification of various electronic devices such as mobile phones and car navigation systems, input devices having light-transmitting touch panels mounted on the front of display elements such as liquid crystals are being used. The operator presses and operates the touch panel with a finger or a pen while viewing the display on the rear display element through the touch panel, thereby switching functions of the device. As such a touch panel, excellent visibility and low cost are required.

图11是特开2005-274667号公报中公开的现有的触摸式面板5001的剖面图。另外，为了便于辨认结构，图中将厚度方向的尺寸放大表示。触摸式面板5001具有透光性，具备薄膜状基板1、透光性基板2、由设于基板1下面的氧化铟锡等透光性电阻体构成的上电阻层3、由设于基板2上面的氧化铟锡等透光性电阻体构成的下电阻层4。在下电阻层4的上面以规定间隔形成有由绝缘树脂构成的多个点隔片。在上电阻层3的两端形成有一对上电极，在下电阻层4的两端形成有在与上电极成直角的方向设置的一对下电极。通过实质上涂敷形成于框缘状的隔片5的上下面的粘合层，将基板1和基板2的外周部分与隔片5贴合，且上电阻层3和下电阻层4隔开规定的间隔相对。FIG. 11 is a cross-sectional view of a conventional touch panel 5001 disclosed in JP-A-2005-274667. In addition, in order to facilitate the identification of the structure, the dimension in the thickness direction is enlarged and shown in the figure. The touch panel 5001 is translucent, and includes afilm substrate 1, atranslucent substrate 2, an upperresistive layer 3 formed of a translucent resistor such as indium tin oxide disposed on the lower surface of thesubstrate 1, and an upperresistive layer 3 disposed on the upper surface of thesubstrate 2. Thelower resistance layer 4 is composed of a light-transmitting resistor such as indium tin oxide. A plurality of dot spacers made of insulating resin are formed at predetermined intervals on the upper surface of thelower resistance layer 4 . A pair of upper electrodes are formed at both ends of the upperresistive layer 3 , and a pair of lower electrodes disposed at right angles to the upper electrodes are formed at both ends of the lowerresistive layer 4 . Substantially apply an adhesive layer formed on the upper and lower surfaces of the frame-shaped spacer 5 , the outer peripheral parts of thesubstrate 1 and thesubstrate 2 are bonded to thespacer 5 , and theupper resistance layer 3 and thelower resistance layer 4 are separated. The specified interval is relative.

薄片6在上面和下面分别形成有粘合层7A、7B。粘合层7A粘贴在基板2的下面，且在粘合层7B上粘贴脱模纸8。Thesheet 6 is formed with adhesive layers 7A, 7B on the upper side and the lower side, respectively. The adhesive layer 7A is attached to the lower surface of thesubstrate 2, and the release paper 8 is attached to the adhesive layer 7B.

在触摸式面板5001上，在将脱模纸8剥离后，将粘结层7B粘贴到液晶显示元件等显示元件的前面而安装到电子设备上。将上电极和下电极与电子设备的电子电路连接。After the release paper 8 is peeled off, the touch panel 5001 is mounted on an electronic device by affixing the adhesive layer 7B to the front surface of a display element such as a liquid crystal display element. Connect the upper and lower electrodes with the electronic circuit of the electronic device.

操作者一边通过触摸式面板5001视认显示元件的显示，一边用手指或笔等按压操作基板1的上面。并且，基板1挠曲，被按压的部位的上电阻层3与下电阻层4接触。将电压从电子电路施加给上电极，且从下电极检测出与上电极的被按压的部位的位置对应的电压。然后，对下电极施加电压，从上电极检测出与下电极的被按压的部位相对应的电压。电子设备通过检测到的电压算出被按压的部位，进行该设备各种功能的切换。The operator presses and operates the upper surface of thesubstrate 1 with a finger, a pen, or the like while viewing the display of the display element on the touch panel 5001 . Then, thesubstrate 1 is bent, and the upperresistive layer 3 and the lowerresistive layer 4 are in contact with the pressed portion. A voltage is applied from the electronic circuit to the upper electrode, and a voltage corresponding to the position of the pressed portion of the upper electrode is detected from the lower electrode. Then, a voltage is applied to the lower electrode, and a voltage corresponding to the pressed portion of the lower electrode is detected from the upper electrode. The electronic device calculates the pressed part through the detected voltage, and switches various functions of the device.

说明触摸式面板5001的制造方法。图12A～图12C是用于说明触摸式面板5001的制造方法的剖面图。A method of manufacturing touch panel 5001 will be described. 12A to 12C are cross-sectional views illustrating a method of manufacturing touch panel 5001 .

如图12A所示，首先，在将基板1和基板2粘贴到隔片5上后，在基板2的下面粘贴薄片6。此时，如图12B所示，通过辊9粘贴薄片6。被辊9推压的基板2的左右向上方挠曲，由此压缩基板1和基板2之间的空气，在基板2的右侧产生向下的膨出2C。其结果是，如图12C所示，以在基板2的下面与薄片6之间产生气泡2D的状态将薄片6粘贴在基板2上。在该触摸式面板通过薄片6与显示元件粘贴的情况下，操作者因气泡2D的存在而难以发现显示元件的显示。As shown in FIG. 12A , first, after thesubstrate 1 and thesubstrate 2 are pasted on thespacer 5 , thesheet 6 is pasted on the lower surface of thesubstrate 2 . At this time, as shown in FIG. 12B , thesheet 6 is pasted by theroller 9 . The left and right sides of thesubstrate 2 pressed by theroller 9 flex upward, thereby compressing the air between thesubstrate 1 and thesubstrate 2 , and generating adownward bulge 2C on the right side of thesubstrate 2 . As a result, as shown in FIG. 12C , thesheet 6 is attached to thesubstrate 2 in a state where air bubbles 2D are generated between the lower surface of thesubstrate 2 and thesheet 6 . When the touch panel is attached to the display element via thesheet 6, it is difficult for the operator to find the display of the display element due to the presence of the air bubbles 2D.

为了防止气泡2D的产生，在基板2上粘贴薄片6时，为了不产生膨出2C而需要调节辊9的按压力或缓缓移动辊9，但制作耗费工序及时间。In order to prevent generation of air bubbles 2D, it is necessary to adjust the pressing force of theroller 9 or move theroller 9 slowly so that thebulge 2C is not generated when thesheet 6 is pasted on thesubstrate 2, but the production process and time are required.

另外，在显示元件上粘贴触摸式面板5001时，存在错位等粘贴偏差的情况。因此，在将触摸式面板5001暂时剥离而重新粘贴到显示元件上时、在触摸式面板5001因粘合层7A而从显示元件剥离的情况下，需要先粘贴在显示元件上后再将残留的薄片6剥离。另外，在触摸式面板5001因粘合层7B而从显示元件剥离的情况下，需要在保持粘贴于显示元件的状态下将残留的粘合层7B除去。因此，两者的情况下，触摸式面板5001的重贴操作繁杂，耗费时间。In addition, when the touch panel 5001 is pasted on the display element, there may be deviations in pasting such as misalignment. Therefore, when the touch panel 5001 is temporarily peeled off and attached to the display element again, or when the touch panel 5001 is peeled off from the display element due to the adhesive layer 7A, it is necessary to first attach the touch panel 5001 to the display element and then attach theremaining Sheet 6 is peeled off. In addition, when the touch panel 5001 is peeled from the display element due to the adhesive layer 7B, it is necessary to remove the remaining adhesive layer 7B while remaining attached to the display element. Therefore, in both cases, the operation of reattaching touch panel 5001 is complicated and time-consuming.

具体实施方式Detailed ways

(实施例1)(Example 1)

图1是本发明实施例1的触摸式面板1001的剖面图。图1B是实施例1的输入装置2001的剖面图。图2是触摸式面板1001的分解立体图。图1、图2中，为了容易判别结构，而将各不分的厚度方向的尺寸放大表示。触摸式面板1001具备基板1、基板2、电阻层3、电阻层4。基板1(第一基板或第二基板)具有上面1A(第二面或第四面)和其相反侧的下面1B(第一面或第三面)。基板2(第二基板或第一基板)具有上面2A(第三面或第一面)和其相反侧的下面2B(第四面或第二面)。基板1和基板2由聚对苯二甲酸乙二酯或及聚碳酸脂等透光性的绝缘薄膜构成。电阻层3(第一电阻层或第二电阻层)设于基板1的下面1B，由氧化铟锡或氧化锡等透光性的电阻材料构成。电阻层4(第二电阻层或第一电阻层)设于基板2的上面2A，由氧化铟锡或氧化锡等透光性的电阻部件构成。电阻层3和电阻层4通过喷溅法等形成。FIG. 1 is a cross-sectional view of atouch panel 1001 according toEmbodiment 1 of the present invention. FIG. 1B is a cross-sectional view of theinput device 2001 of the first embodiment. FIG. 2 is an exploded perspective view oftouch panel 1001 . In FIG. 1 and FIG. 2 , in order to easily distinguish the structure, the dimensions in the thickness direction are shown enlarged without distinction.Touch panel 1001 includessubstrate 1 ,substrate 2 ,resistive layer 3 , andresistive layer 4 . The substrate 1 (first substrate or second substrate) has anupper surface 1A (second surface or fourth surface) and a lower surface 1B (first surface or third surface) on the opposite side. The substrate 2 (second substrate or first substrate) has an upper surface 2A (third surface or first surface) and a lower surface 2B (fourth surface or second surface) on the opposite side. Thesubstrate 1 and thesubstrate 2 are made of a light-transmitting insulating film such as polyethylene terephthalate or polycarbonate. The resistance layer 3 (first resistance layer or second resistance layer) is provided on the lower surface 1B of thesubstrate 1 and is made of a light-transmitting resistance material such as indium tin oxide or tin oxide. Resistive layer 4 (second resistive layer or first resistive layer) is provided on upper surface 2A ofsubstrate 2 and is made of a translucent resistive member such as indium tin oxide or tin oxide.Resistance layer 3 andresistance layer 4 are formed by sputtering or the like.

在电阻层3的方向1001A的两端设有由银或碳等导电部件构成的电极32A、32B。在与方向1001A成直角的方向1001B的电阻层4的两端形成有由银及碳等导电部件构成的电极33A、33B。Electrodes 32A and 32B made of conductive members such as silver or carbon are provided at both ends of theresistance layer 3 in the direction 1001A. Electrodes 33A and 33B made of conductive members such as silver and carbon are formed at both ends of theresistance layer 4 in a direction 1001B perpendicular to the direction 1001A.

隔片15实质上具有框缘形状，由无纺布或聚脂薄膜等绝缘部件构成。在隔片15的上面15A上涂敷丙烯酸类或橡胶等粘合材料，并在上面15A上粘贴基板1的外周部分1E。同样，在隔片15的下面15B上涂敷丙烯酸类或橡胶等粘合材料，并在下面15B上粘贴基板2的外周部分2E。电阻层3的下面3B和电阻层4的上面4A隔开规定的间隙而相对。在电阻层4的上面4A上以规定的间隔形成有由环氧树脂或硅等绝缘树脂构成的多个点隔片31。Thespacer 15 has a substantially frame shape and is made of an insulating member such as nonwoven fabric or polyester film. An adhesive material such as acrylic or rubber is applied to the upper surface 15A of thespacer 15, and the outer peripheral portion 1E of thesubstrate 1 is attached to the upper surface 15A. Similarly, an adhesive material such as acrylic or rubber is applied to the lower surface 15B of thespacer 15, and the outer peripheral portion 2E of thesubstrate 2 is attached to the lower surface 15B. Lower surface 3B ofresistance layer 3 and upper surface 4A ofresistance layer 4 face each other with a predetermined gap therebetween. A plurality ofdot spacers 31 made of insulating resin such as epoxy resin or silicon are formed at predetermined intervals on upper surface 4A ofresistance layer 4 .

薄片16由聚对苯二甲酸乙二酯或聚碳酸脂等透光性薄膜构成。薄片16具有上面16A(第五面)和其相反侧的下面16B(第六面)。在薄片16的上面16A上涂敷丙烯酸脂等强粘着性的粘合剂，形成粘合层17A。通过粘合层17A将薄片16粘贴到基板2的下面2B。在薄片16的下面16B上涂敷硅橡胶等弱粘着性粘合剂，形成粘合层17B。在粘合层17B上粘合有由纸或聚脂薄膜等薄膜构成的脱模片18。粘合层17B的粘合力比粘合层17A弱。Thesheet 16 is made of a light-transmitting film such as polyethylene terephthalate or polycarbonate. Thesheet 16 has an upper surface 16A (fifth surface) and a lower surface 16B (sixth surface) on the opposite side. A strong adhesive such as acrylate is applied to the upper surface 16A of thesheet 16 to form anadhesive layer 17A. Thesheet 16 is attached to the lower surface 2B of thesubstrate 2 through theadhesive layer 17A. A weakly adhesive adhesive such as silicone rubber is applied to the lower surface 16B of thesheet 16 to form anadhesive layer 17B. A release sheet 18 made of a film such as paper or mylar is bonded to theadhesive layer 17B. The adhesive force of theadhesive layer 17B is weaker than that of theadhesive layer 17A.

如图1B所示，将脱模片18剥离，将薄片16的下面16B的粘合层17B粘贴到液晶显示元件等显示元件101的显示面101A上，得到输入装置2001。As shown in FIG. 1B , the release sheet 18 is peeled off, and theadhesive layer 17B on the lower surface 16B of thesheet 16 is attached to the display surface 101A of adisplay element 101 such as a liquid crystal display element to obtain aninput device 2001 .

隔片15的局部被切断，形成将其框缘形状的内部15D和外部15E连通的开口部15C。薄片16具有向外侧突出的部分即舌片部16C。舌片部16C向上方弯曲，覆盖并堵住隔片15的开口部15C，通过强粘着性的粘合剂17A将舌片部16C的前端16D粘贴到基板1的上面1A。A part of thespacer 15 is cut to form anopening 15C that communicates the frame-shaped interior 15D and exterior 15E. Thesheet 16 has atongue portion 16C that protrudes outward. Thetongue portion 16C is bent upward to cover and block theopening 15C of thespacer 15 , and thefront end 16D of thetongue portion 16C is bonded to theupper surface 1A of thesubstrate 1 with astrong adhesive 17A.

图3A～图3C是表示触摸式面板1001的制造方法的分解剖面图。如图3A所示，首先在隔片15的上面15A和下面15B分别粘贴基板1和基板2，然后，通过粘合层17A在基板2的下面2B上粘贴薄片16。通过粘合层17A在基板2的下面2B粘贴薄片16时，如图3B所示，利用辊9将薄片16向基板1方向推压到基板2上。由辊9推压的基板2的左侧部分向上方即基板1挠曲，由此，将基板1和基板2之间的空气压缩。此时，由于空气从设于隔片15上的开口部15C进出，因此，在基板2上不会产生向下方的膨出(图12A所示的膨出2C)。因此，在基板2和薄片16之间不会产生因基板2的膨出而产生的气泡(图12C所示的气泡2D)。即，即使辊9较强地推压或一定程度地快速移动，也可以以在基板2的下面2B和薄片16之间不产生防碍显示元件101的视认的气泡的状态下将薄片16和基板2粘贴。3A to 3C are exploded cross-sectional views illustrating a method ofmanufacturing touch panel 1001 . As shown in FIG. 3A , thesubstrate 1 and thesubstrate 2 are first attached to the upper surface 15A and the lower surface 15B of thespacer 15 , and then thesheet 16 is attached to the lower surface 2B of thesubstrate 2 through theadhesive layer 17A. When thesheet 16 is pasted on the lower surface 2B of thesubstrate 2 through theadhesive layer 17A, thesheet 16 is pressed onto thesubstrate 2 by theroller 9 toward thesubstrate 1 as shown in FIG. 3B . The left part of thesubstrate 2 pressed by theroller 9 deflects upward, that is, thesubstrate 1 , thereby compressing the air between thesubstrate 1 and thesubstrate 2 . At this time, since air enters and exits through theopening 15C provided in thespacer 15 , downward bulging (bulging 2C shown in FIG. 12A ) does not occur on thesubstrate 2 . Therefore, air bubbles (bubbles 2D shown in FIG. 12C ) generated by the swelling of thesubstrate 2 are not generated between thesubstrate 2 and thesheet 16 . That is, even if theroller 9 pushes strongly or moves quickly to a certain extent, thesheet 16 and thesheet 16 can be placed between the lower surface 2B of thesubstrate 2 and thesheet 16 without generating air bubbles that hinder the visibility of thedisplay element 101.Substrate 2 is pasted.

然后，如图3C所示，将薄片16的舌片部16C向上方折曲，覆盖隔片15的开口部15C。进而将舌片部16C的前端16D折曲，通过粘合层17A粘贴在基板1的上面1A上，得到图1所示的触摸式面板1001。Then, as shown in FIG. 3C , thetongue portion 16C of thesheet 16 is bent upward to cover theopening 15C of thespacer 15 . Furthermore, thefront end 16D of thetongue part 16C is bent, and it sticks to theupper surface 1A of the board|substrate 1 through theadhesive layer 17A, and thetouch panel 1001 shown in FIG. 1 is obtained.

在实施例1的触摸式面板1001中，在粘贴于基板1和基板2上的实质上框缘状的隔片15上设有开口部15C。在基板2的下面2B上粘贴薄片16时，通过使空气从开口部15C进出，能够防止基板2的膨出，且能够在没有气泡的状态下将薄片16粘贴在基板2上。在粘贴了薄片16后，通过由舌片部16C将开口部15C覆盖，可防止周围的尘埃或湿气侵入基板1和基板2之间，且可稳定地操作触摸式面板1001。Intouch panel 1001 of Example 1,opening 15C is provided in substantially frame-shapedspacer 15 attached tosubstrate 1 andsubstrate 2 . When attaching thesheet 16 to the lower surface 2B of thesubstrate 2, the expansion of thesubstrate 2 can be prevented by letting air in and out through theopening 15C, and thesheet 16 can be attached to thesubstrate 2 without air bubbles. After thesheet 16 is attached, by covering theopening 15C with thetongue 16C, surrounding dust and moisture can be prevented from entering between thesubstrate 1 and thesubstrate 2, and thetouch panel 1001 can be operated stably.

另外，薄片16的下面16B的粘合层17B及脱模片18也可以具有向外侧突出的舌片部。In addition, theadhesive layer 17B and the release sheet 18 on the lower surface 16B of thesheet 16 may have a tongue part protruding outward.

在将脱模片18剥离后，利用弱粘着性的粘合层17B将触摸式面板1001的薄片16的下面16B粘贴在显示元件101上，并安装到电子设备上。将电极32A、32B和电极33A、33B与设备的电子电路连接。After the release sheet 18 is peeled off, the lower surface 16B of thesheet 16 of thetouch panel 1001 is pasted on thedisplay element 101 with the weakly adhesiveadhesive layer 17B, and mounted on the electronic device. The electrodes 32A, 32B and electrodes 33A, 33B are connected to the electronic circuitry of the device.

操作者一边通过触摸式面板1001视认显示元件101的显示面101A上的显示，一边用手指或笔按压基板1的上面1A时，基板1挠曲，被推压的部位的电阻层3与电阻层4接触。电子电路在电极32A、32B之间施加电压，并检测电极33A或电极33B的电压。电子电路从检测到的电压算出被按压的部位的方向1001A的位置。然后，电子电路在电极33A、33B之间施加电压，并检测电极32A或电极32B的电压。电子电路从检测到的电压算出被按压的部位的方向1001B的位置。由此，能够算出被按压的部位的方向1001A、1001B的位置。电子电路根据算出的位置切换设备的各个功能。When the operator presses theupper surface 1A of thesubstrate 1 with a finger or a pen while viewing the display on the display surface 101A of thedisplay element 101 through thetouch panel 1001, thesubstrate 1 bends, and theresistive layer 3 and the resistor at the pushedpart Layer 4 contacts. The electronic circuit applies a voltage between the electrodes 32A, 32B and detects the voltage of the electrode 33A or the electrode 33B. The electronic circuit calculates the position of the pressed part in the direction 1001A from the detected voltage. The electronic circuit then applies a voltage between the electrodes 33A, 33B and detects the voltage of either the electrode 32A or the electrode 32B. The electronic circuit calculates the position of the pressed part in the direction 1001B from the detected voltage. Thereby, the position of the pressed part in the direction 1001A, 1001B can be calculated. Depending on the calculated position, the electronic circuit switches the various functions of the device.

在将触摸式面板1001粘贴到显示元件101上时，有因错位等而产生粘贴偏差的情况。在触摸式面板1001中，薄片16的上面16A的粘合层17A为强粘着性，下面16B的粘合层17B具有粘合力比粘合层17A弱的弱粘着性。因此，在将触摸式面板1001粘贴到显示元件101上后，即使将触摸式面板1001从显示元件101剥离，薄片16也不会从基板2剥离，可再次粘贴到显示元件101上。When thetouch panel 1001 is attached to thedisplay element 101, there may be deviation in the attachment due to misalignment or the like.

A plurality of dot spacers 531 made of insulating resin such as epoxy resin or silicon are formed at predetermined intervals on upper surface 504A ofresistance layer 504 .

透光性薄片516由聚对苯二甲酸乙二醇酯或聚碳酸脂等透光性薄膜构成。薄片516具有上面516A和其相反侧的下面516B。在薄片516的上面516A上形成丙烯酸类等对玻璃的粘合力为0.1～20N/cm的强粘着性粘合层517A，通过强粘着性粘合层517A将薄片516粘贴到基板502的下面502B上。Thetranslucent sheet 516 is made of a translucent film such as polyethylene terephthalate or polycarbonate. Thesheet 516 has an upper surface 516A and an opposite lower surface 516B. On the upper surface 516A of thesheet 516, a strongly adhesiveadhesive layer 517A having an adhesive force of acrylic or the like to glass of 0.1 to 20 N/cm is formed, and thesheet 516 is attached to thelower surface 502B of thesubstrate 502 through the strongly adhesiveadhesive layer 517A. superior.

在薄片516的下面516B上形成有烯烃类或苯乙烯类的对玻璃的粘合力为0.01～0.5N/cm的弱粘着性粘合剂517B。在粘合层517B上粘合有由纸或薄膜等柔软性薄膜构成的脱模片508。即，设定粘合层517B的粘合力比粘合层517A弱。On the lower surface 516B of thesheet 516, an olefin-based or styrene-based weaklytacky adhesive 517B having an adhesive force of 0.01 to 0.5 N/cm to glass is formed. A release sheet 508 made of a flexible film such as paper or film is bonded to theadhesive layer 517B. That is, the adhesive force of theadhesive layer 517B is set to be weaker than that of theadhesive layer 517A.

图9是实施例2的输入装置3001的剖面图。将触摸式面板2001的脱模片508剥离，然后，将粘合层517B粘贴到液晶显示元件等显示元件510的显示面510A上。电极532A、532B和电极533A、533B与设备的电子电路连接，并安装在电子设备上。FIG. 9 is a cross-sectional view of theinput device 3001 of the second embodiment. Release sheet 508 oftouch panel 2001 is peeled off, andadhesive layer 517B is attached to displaysurface 510A ofdisplay element 510 such as a liquid crystal display element.Electrodes 532A, 532B andelectrodes 533A, 533B are connected to the electronic circuitry of the device and mounted on the electronic device.

操作者一边通过触摸式面板2001视认显示元件510的显示面510A上的显示，一边用手指或笔按压基板501的上面501A时，基板501挠曲，被推压的部位的电阻层503与电阻层504接触。电子电路在电极532A、532B之间施加电压，并检测电极533A或电极533B的电压。电子电路从检测到的电压算出被按压部位的方向2001A的位置。然后，电子电路在电极533A、533B之间施加电压，并检测电极532A或电极532B的电压。电子电路从检测到的电压算出被按压的部位的方向2001B的位置。由此，能够算出被按压的部位的方向2001A、2001B的位置。电子电路根据算出的位置切换设备的各个功能。When the operator presses theupper surface 501A of thesubstrate 501 with a finger or a pen while viewing the display on thedisplay surface 510A of thedisplay element 510 through thetouch panel 2001, thesubstrate 501 bends, and theresistive layer 503 and the resistor at the pushedpart Layer 504 contacts. Electronic circuitry applies a voltage betweenelectrodes 532A, 532B and detects the voltage at eitherelectrode 533A orelectrode 533B. The electronic circuit calculates the position of the pressed part in thedirection 2001A from the detected voltage. The electronic circuit then applies a voltage between theelectrodes 533A, 533B and detects the voltage on either theelectrode 532A or theelectrode 532B. The electronic circuit calculates the position of the pressed part in thedirection 2001B from the detected voltage. Thereby, the position of the pressed part in thedirection 2001A, 2001B can be calculated. Depending on the calculated position, the electronic circuit switches the various functions of the device.

在将触摸式面板2001粘贴到显示元件510上时，有因错位等而产生粘贴偏差的情况。由于触摸式面板2001通过薄片516的下面516B的弱粘着性粘合层517B而粘贴在显示元件510上，因此，触摸式面板2001容易从显示元件510上暂时剥离，并重新贴到显示元件510上。When stickingtouch panel 2001 to displayelement 510 , there may be a sticking deviation due to misalignment or the like. Since thetouch panel 2001 is pasted on thedisplay element 510 through the weak adhesiveadhesive layer 517B on the lower surface 516B of thesheet 516, thetouch panel 2001 is easily peeled off from thedisplay element 510 temporarily and reattached to thedisplay element 510. .

即，在将触摸式面板2001从显示元件510剥离时，薄片516和基板502由强粘着性粘合层517A粘结，且显示元件510和薄片516由粘合力比强粘着性粘合层517A弱的弱粘着性粘合层517B粘结。因此，薄片516继续粘结在基板502上，从显示元件510剥离。因此，在将触摸式面板2001剥离后，不需要将薄片516从显示元件510再次剥离。That is, when thetouch panel 2001 is peeled off from thedisplay element 510, thesheet 516 and thesubstrate 502 are bonded by the strongly adhesiveadhesive layer 517A, and thedisplay element 510 and thesheet 516 are bonded by the strongeradhesive layer 517A. The weakly weakly tackyadhesive layer 517B is bonded. Thus, thesheet 516 remains bonded to thesubstrate 502 and peels away from thedisplay element 510 . Therefore, after thetouch panel 2001 is peeled off, it is not necessary to peel thesheet 516 from thedisplay element 510 again.

弱粘着性粘合层517B以对玻璃的粘合力弱到0.01～0.5N/cm的程度涂敷在薄片516的下面516B上，因此，弱粘着性粘合层517B不会转印并附着在显示元件510上。因此，在剥离后，不需要去除附着在显示元件510上面的粘合层517B。The weakly adhesiveadhesive layer 517B is coated on the lower surface 516B of thesheet 516 with an adhesive force to glass as weak as 0.01 to 0.5 N/cm. Therefore, the weakly adhesiveadhesive layer 517B does not transfer and adheres to the surface.Display element 510 on. Therefore, there is no need to remove theadhesive layer 517B attached on thedisplay element 510 after peeling.

弱粘着性粘合层517B可由硅橡胶或聚氨酯橡胶等单体材料形成。在实施例2中，由于弱粘着性粘合层517B由烯烃类或苯乙烯类、酯类、聚氯乙烯类等热塑性弹性材料形成，因此，可容易地通过材料的混合比调节弱粘着性粘合层517B的粘合力。The weakadhesive layer 517B can be formed of a monomer material such as silicone rubber or urethane rubber. InEmbodiment 2, since the weakly tackyadhesive layer 517B is formed of thermoplastic elastic materials such as olefins, styrenes, esters, and polyvinyl chlorides, the weakly tacky adhesive layer can be easily adjusted by the mixing ratio of the materials. Adhesion oflaminated layer 517B.

弱粘着性粘合层517B含有柔性链段和粘合力比柔性链段大的硬性链段。在弱粘着性粘合层517B由烯烃类热塑性弹性材料构成的情况下，含有作为柔性链段的乙烯一丙烯和作为硬性链段的聚乙烯·聚丙烯。在弱粘着性粘合层517B由苯乙烯类热塑性弹性材料构成的情况下，含有作为柔性链段的聚丁二烯和作为硬性链段的聚苯乙烯。在弱粘着性粘合层517B由尿烷类热塑性弹性材料构成的情况下，含有作为硬性链段的聚酯·聚醚和作为柔性链段的聚氨酯。在弱粘着性粘合层517B由酯类热塑性弹性材料构成的情况下，含有作为硬性链段的聚醚·聚酯和作为柔性链段的聚酯。在弱粘着性粘合层517B由聚氯乙烯类热塑性弹性材料构成的情况下，含有作为硬性链段的非结晶性聚氯乙烯和作为柔性链段的结晶性聚氯乙烯。The weakly adhesiveadhesive layer 517B includes a soft segment and a hard segment having a higher adhesive force than the soft segment. When the weakly adhesiveadhesive layer 517B is made of an olefin-based thermoplastic elastic material, it contains ethylene-propylene as a soft segment and polyethylene/polypropylene as a hard segment. In the case where the weakly adhesiveadhesive layer 517B is made of a styrene-based thermoplastic elastic material, it contains polybutadiene as a soft segment and polystyrene as a hard segment. When the weakly adhesiveadhesive layer 517B is made of a urethane-based thermoplastic elastic material, it contains polyester/polyether as a hard segment and polyurethane as a soft segment. When the weakly adhesiveadhesive layer 517B is made of an ester-based thermoplastic elastic material, it contains polyether/polyester as a hard segment and polyester as a soft segment. When the weakly adhesiveadhesive layer 517B is made of a polyvinyl chloride-based thermoplastic elastic material, it contains amorphous polyvinyl chloride as a hard segment and crystalline polyvinyl chloride as a soft segment.

弱粘着性粘合层517B含有热塑性弹性材料的粘合力互不相同的元素，由此，通过这些元素的混合比，可容易地调节弱粘着性粘合层517B的粘合力。因此，可根据强粘着性粘合层517A的粘合力来调节弱粘着性粘合层517B的粘合力，且可以以所希望的剥离力将触摸式面板2001从显示元件510剥离。The weakly-adhesive adhesive layer 517B contains elements having mutually different adhesive forces of thermoplastic elastic materials, whereby the adhesive force of the weakly-adhesive adhesive layer 517B can be easily adjusted by the mixing ratio of these elements. Therefore, the adhesive force of the weakly adhesiveadhesive layer 517B can be adjusted according to the adhesive force of the strongly adhesiveadhesive layer 517A, and thetouch panel 2001 can be peeled from thedisplay element 510 with a desired peeling force.

在将触摸式面板2001从显示元件510剥离时，由于必须将弱粘着性粘合层517B从显示元件510剥离，因此，优选将对玻璃的粘合力为1～10N/cm的材料用作强粘着性粘合层517A，使弱粘着性粘合层517B的粘合力更强。When peeling thetouch panel 2001 from thedisplay element 510, since the weakly adhesiveadhesive layer 517B must be peeled off from thedisplay element 510, it is preferable to use a material having an adhesive force of 1 to 10 N/cm to glass as the strongadhesive layer 517B. The tackyadhesive layer 517A strengthens the adhesive force of the weakly tackyadhesive layer 517B.

图10A是实施例3的触摸式面板2002的剖面图。图10B是实施例3的输入装置3002的剖面图。图10A、图10B中，与图8A所示的触摸式面板2001及图9所示的输入装置3001相同的部分标注相同的符号，省略其说明。FIG. 10A is a cross-sectional view of a touch panel 2002 according to the third embodiment.

In FIGS. 10A and 10B , the same parts astouch panel 2001 shown in FIG. 8A andinput device 3001 shown in FIG. 9 are denoted by the same reference numerals, and description thereof will be omitted.

在触摸式面板2002中，基板501由聚碳酸脂或聚醚砜构成，基板502由聚碳酸脂、聚醚砜、玻璃等构成。触摸式面板2002具有薄片1516代替触摸式面板2001的薄膜516。薄片1516是由将聚碳酸脂或环烯聚合物等薄膜延伸且具有多折曲性的1/4波长的相位差板。In touch panel 2002 ,substrate 501 is made of polycarbonate or polyethersulfone, andsubstrate 502 is made of polycarbonate, polyethersulfone, glass, or the like. Touch panel 2002 has sheet 1516 instead offilm 516 oftouch panel 2001 . The sheet 1516 is a 1/4 wavelength retardation plate that is stretched from a film such as polycarbonate or cycloolefin polymer and has multiple bends.

在基板501的上面501A上设有由与薄片1561相同的材质构成的相位差板520。在相位差板520的上面520A上设有偏振光板521。偏振光板521由吸附碘或染料并使其延伸、定向的聚乙烯醇薄片和在该薄片的上面和下面层叠的三乙酰纤维素构成。通过相位差板520和薄片1516构成圆偏振光型触摸式面板2001。A phase difference plate 520 made of the same material as the sheet 1561 is provided on theupper surface 501A of thesubstrate 501 . A polarizing plate 521 is provided on the upper surface 520A of the phase difference plate 520 . The polarizing plate 521 is composed of a polyvinyl alcohol sheet that absorbs iodine or a dye to extend and align it, and triacetyl cellulose laminated on the upper and lower surfaces of the sheet. The circularly polarized lighttype touch panel 2001 is constituted by the retardation plate 520 and the sheet 1516 .

在触摸式面板2002中，与触摸式面板2001相同，通过触摸式面板2002从偏振光板521的上面521A视认粘贴于薄膜1516的下面1516B上的显示元件510。在来自于偏振光板521上方的太阳光或灯光等外部光透过偏振光板521时，在外部光的X方向及与其正交的Y方向的偏振光中，例如偏振光板521吸收Y方向的偏振光。通过偏振光板521的外部光成为X方向的直线偏振光，从偏振光板521入射到相位差板520上。In touch panel 2002 , liketouch panel 2001 ,display element 510 attached to lower surface 1516B of film 1516 is viewed from upper surface 521A of polarizing plate 521 through touch panel 2002 . When external light such as sunlight or lamp light from above the polarizing plate 521 passes through the polarizing plate 521, among the polarized light in the X direction of the external light and the Y direction perpendicular thereto, for example, the polarizing plate 521 absorbs the polarized light in the Y direction. . External light passing through the polarizer 521 becomes linearly polarized light in the X direction, and enters the retardation plate 520 from the polarizer 521 .

其次，该光通过1/4波长的相位差板520使偏振光面仅旋转45度。通过基板501或电阻层503由电阻层504朝向偏振光板521向上方反射。Next, the light passes through the retardation plate 520 of 1/4 wavelength to rotate the plane of polarization by only 45 degrees. Through thesubstrate 501 or theresistive layer 503 , theresistive layer 504 reflects upward toward the polarizing plate 521 .

反射了的光再次透过1/4波长的相位差板520使其偏振光面仅旋转45度。由此，入射到相位差板520上的光错开1/2波长即使偏振光面仅旋转90度，再次从相位差板520射出，入射到偏振光板521上。由于偏振光板521仅使X方向的光波透过，因此，将从相位差板520射出的光遮断，不会从上面521A射出。The reflected light passes through the retardation plate 520 of 1/4 wavelength again so that the polarization plane is rotated by only 45 degrees. Thus, the light incident on the retardation plate 520 is shifted by 1/2 wavelength even if the polarization plane is only rotated by 90 degrees, and then exits the retardation plate 520 again and enters the polarizing plate 521 . Since the polarizing plate 521 transmits only light waves in the X direction, it blocks light emitted from the retardation plate 520 and does not emit from the upper surface 521A.

即，从偏振光板521的上面521A的上方入射的外部光由电阻层504向上方反射。但是，该反射光被偏振光板521遮断，不会从上面521A射出。因此，得到不会被反射、识别性优良且容易看到显示元件的显示的触摸式面板2002。That is, external light incident from above the upper surface 521A of the polarizing plate 521 is reflected upward by theresistive layer 504 . However, this reflected light is blocked by the polarizing plate 521 and is not emitted from the upper surface 521A. Therefore, touch panel 2002 is obtained that is not reflected, has excellent visibility, and is easy to see the display of the display element.

在显示元件510是液晶显示元件时，来自于显示元件510的光具有规定的偏振光。在输入装置3002上，显示元件510为射出Y方向的直射偏振光而设置。来自于显示元件510的光先透过1/4波长的薄片1516和1/4波长的相位差板520，构成错开1/2波长的X方向的直线偏振光，入射到偏振光板521。由于偏振光板521使X方向的偏振光通过，因此，从显示元件510射出后透射通过薄片1516和相位差板520的光，从上面521A射出。因此，能够明确地视认显示元件510的显示。When thedisplay element 510 is a liquid crystal display element, the light from thedisplay element 510 has predetermined polarization. On the input device 3002, thedisplay element 510 is provided to emit direct polarized light in the Y direction. The light from thedisplay element 510 first passes through the 1/4 wavelength sheet 1516 and the 1/4 wavelength retardation plate 520 to form linearly polarized light in the X direction shifted by 1/2 wavelength, and enters the polarizing plate 521 . Since the polarizing plate 521 passes polarized light in the X direction, the light emitted from thedisplay element 510 and transmitted through the sheet 1516 and the retardation plate 520 is emitted from the upper surface 521A. Therefore, the display of thedisplay element 510 can be clearly recognized.

通过薄片1516的下面1516B的弱粘着性粘合层517B，可容易地将触摸式面板2002从显示元件510剥离，且粘合层517B不会附着在显示元件510的上面。因此，可容易地将粘贴后的触摸式面板2002再次粘贴到显示元件510上。Through the weakly adhesiveadhesive layer 517B on the lower surface 1516B of the sheet 1516 , the touch panel 2002 can be easily peeled off from thedisplay element 510 without theadhesive layer 517B being attached to the upper surface of thedisplay element 510 . Therefore, the pasted touch panel 2002 can be easily pasted on thedisplay element 510 again.

根据实施例3，通过将粘贴于基板502的下面502B上的薄片516作为1/4波长的相位差板，可得到构成零件数量少，视认性优良，且容易看到显示元件的触摸式面板2002及使用该触摸式面板的输入装置3002。According to Example 3, by using thesheet 516 attached to thelower surface 502B of thesubstrate 502 as a retardation plate of 1/4 wavelength, a touch panel with a small number of components, excellent visibility, and easy to see display elements can be obtained. 2002 and an input device 3002 using the touch panel.
