The invention provides a capacitive touch screen and financial payment electronic equipment with the same.
Referring to fig. 1 to 6, in an embodiment of the present invention, the capacitive touch screen 10 is mainly used for financial payment electronic devices, particularly unattended financial payment electronic products, such as ATM machines, for a user to input information, such as a password, on the capacitive touch screen 10, although other financial payment products requiring a touch screen to input information may also be suitable. Specifically, the present capacitive touch includes a touch screen body 1 and a touch control panel 2. The touch screen body 1 comprises an upper glass layer 12a, an upper protection signal layer 13a, a signal receiving layer 15a, a signal sending layer 15b, a lower protection signal layer 13b and a lower glass substrate 12b which are sequentially laminated from top to bottom, wherein the upper protection signal layer 13a and the lower protection signal layer 13b completely cover the signal receiving layer 15a and the signal sending layer 15 b; the touch control panel 2 is electrically connected with the upper protection signal layer 13a, the receiving signal layer 15a, the sending signal layer 15b and the lower protection signal layer 13 b; the touch control board 2 is configured to clear sensitive information stored inside the touch control board 2 when the electrical signal of the upper protection signal layer 13a and/or the lower protection signal layer 13b is not received, wherein the sensitive information includes, but is not limited to, a key, a PIN code, and other data.
It should be noted that, the touch screen body 1 specifically includes the following layers stacked from top to bottom: the anti-reflection cover coating 11, the upper glass layer 12a, the upper protection signal layer 13a, the first optical adhesive layer 14a, the signal receiving layer 15a, the second optical adhesive layer 14b, the signal sending layer 15b, the third optical adhesive layer 14c, the lower protection signal layer 13b, the lower glass substrate 12b, the peep-proof film 16 and the anti-dismantling flexible circuit 17. Wherein, the anti-reflection covering coating 11 can avoid the problem of unclear display caused by the reflection of the glass; the upper glass layer 12a and the lower glass substrate 12b play a role in protecting and supporting the layers sandwiched therebetween, the material is preferably strengthened glass with high impact strength, and particularly the upper glass layer 12a can protect the signal receiving layer 15a from being affected by dirt or dust, so that the capacitive touch screen 10 can accurately calculate the touch position; the first optical adhesive layer 14a, the second optical adhesive layer 14b, and the third optical adhesive layer 14c are preferably made of OCA optical adhesive, and the OCA optical adhesive is optically transparent double-sided adhesive, so that the light transmittance of the capacitive touch screen 10 can be ensured. In addition, in the technical scheme of the invention, the secret key is the primary sensitive information, and before the product is on line, a worker exports the secret key to the inside of the chip of the touch control panel 2 from a bank background in a safe room; the next sensitive information is a locally stored PIN password buffer for individual users. In the actual use process of the capacitive touch screen 10, the touch screen body 1 is divided into a visible area 1b for users to click and a non-visible area 1b1a located at the periphery of the visible area 1b, in the visible area 1b, the signal receiving layer 15a and the signal sending layer 15b form a rhombic interlaced pattern in the visible area 1b, then the FPC flat cable 3 leading to the capacitive touch screen 10 is concentrated through the non-visible area 1b1a, and finally the FPC flat cable 3 leads to the IO pins of the touch control board 2. When the touch panel is used, the driving end of the receiving signal layer 15a generates a periodic driving pulse, and then the sending signal layer 15b detects the change of the electric pulse, so as to determine whether a touch event occurs at the position, specifically, a capacitance is generated when a line led out from the receiving signal layer 15a and a line led out from the sending signal layer 15b are overlapped, and once the touch event is touched, the change of the capacitance value is generated, so that the touch panel 2 can calculate the touch position according to the corresponding ground current value. Here, the same wiring of the non-visible region 1b1a cannot overlap the cross wiring, which would otherwise affect the operation of the capacitive touch panel 10.
In this embodiment, since the upper protection signal layer 13a is completely covered on the upper surface of the receiving signal layer 15a, the upper protection signal layer 13a is completely covered on the lower surface of the transmitting signal layer 15b, and both the upper protection signal layer 13a and the lower protection signal layer 13b are electrically connected to the touch control board 2, i.e. under normal conditions, both the upper protection signal layer 13a and the lower protection signal layer 13b are in an electrically conducting state, when the capacitive touch screen 10 is damaged, the circuit of the upper protection signal layer 13a and/or the lower protection signal is first damaged and disconnected, so that the touch control board 2 can sense that the circuit is damaged and then sensitive information is completely deleted, thus it is possible to prevent others from analyzing and even obtaining relevant sensitive information such as a password input by a cardholder by stealing the line of the transmitting signal layer 15b, and thus it is possible to effectively improve the application to financial payment electronic devices, especially the safety performance of unattended financial payment electronic products such as ATM machines. In addition, the technical scheme of the invention can effectively improve the safety performance of payment, so the design and production difficulty of ATM products can be reduced, the aesthetic property and the technological sense of the products can be improved, and the use experience of cardholders can be greatly enhanced.
Specifically, in the present embodiment, each of the upper protective signal layer 13a, the receiving signal layer 15a, the transmitting signal layer 15b, and the lower protective signal layer 13b includes a transparent base film and an ITO (Indium Tin oxide) conductive layer laminated on the transparent base film, so as to achieve both conductivity and light transmittance. The transparent base film can be made of materials such as PET (polyethylene terephthalate) with good light transmission performance preferably so as to support the ITO conducting layer, and silver paste lines are etched on the surface of the ITO conducting layer so as to form a related circuit.
Referring to fig. 2 to 4, in the present embodiment, since the visible region 1b is usually made of transparent material, it is very difficult for a lawbreaker to modify the circuit and monitor the signal line thereon without being detected by the cardholder, so the emphasis on protecting the signal line should be on the non-visible region 1b1 a. Specifically, the non-visible area 1b1a of the touch screen body 1 includes a blank area and a wiring area 151 provided with a lead, wherein the blank area is above the wiring area 151 of the signal transmitting layer 15b, i.e., the blank area of the signal receiving layer 15a, and preferably, the signal receiving layer 15a is provided with a cover line 150 in the blank area, and the cover line 150 covers the wiring area 151 of the signal transmitting layer 15b to protect the signal, in other words, two protective layers, i.e., the upper protective signal layer 13a and the cover layer, are overlapped on the wiring area 151 of the signal transmitting layer 15b provided with the lead, so that the touch screen body 1 is provided with a double protection mechanism in the non-visible area 1b1a, thereby further improving the safety performance of the capacitive touch screen 10.
Further, as shown in fig. 4, in the present embodiment, the cover line 150 is preferably arranged in a meander shape to obtain as large a cover protection density as possible. Specifically, the cover line 150 is a serpentine line, and may be formed by etching a silver paste line on a transparent base film, or may be formed by a copper line. Of course, in other embodiments, the cover line 150 may have other shapes as long as it can cover the wiring region 151 of the signal transmission layer 15 b. Similarly, the cover line 150 may also be electrically connected to the touch control board 2, and when the cover line 150 is broken, the touch control board 2 may sense that the circuit is broken and the sensitive information is immediately deleted, thereby protecting the sensitive signal.
Further, in this embodiment, the capacitive touch screen 10 further includes a FPC cable 3, and the FPC cable 3 is disposed in a multilayer board with high security, and includes a cable body layer (not labeled), and an upper protection wire layer (not labeled) and a lower protection wire layer (not labeled) respectively disposed on the upper and lower sides of the cable body layer; the receiving signal layer 15a and the sending signal layer 15b are electrically connected with the touch control panel 2 through the flat cable body layer; the upper protection wire layer and the lower protection wire layer are electrically connected with the touch control panel 2. Specifically, the flat cable body layer includes a sensitive signal layer and a ground circuit layer stacked up and down, and both the reception signal and the transmission signal are electrically connected to the touch control panel 2 through the sensitive signal layer. It can be understood that when the upper protection line layer and/or the lower protection line layer is broken due to damage, the touch control panel 2 can sense that the circuit is damaged and immediately delete the sensitive information.
Also, in the present embodiment, both the upper and lower guard line layers are preferably arranged in a serpentine shape to obtain as large a coverage protection density as possible. Specifically, the upper and lower guard line layers are both serpentine and are formed by copper wires, but in other embodiments, the cover line 150 may be disposed in other shapes or made of other conductive materials.
Referring to fig. 1, in the present embodiment, the capacitive touch screen 10 further includes a privacy film 16, and the privacy film 16 is attached to a surface of the lower glass substrate 12b facing away from the lower protective signal layer 13 b. Here, the peep-proof film 16 may prevent others or the camera from seeing clearly the display contents on the touch screen when looking at the touch screen at a certain angle range, so that the input password of the cardholder can be prevented from being observed or photographed by the irrelevant people at the side and the camera above the bank hall.
Referring to fig. 5 and 6 together, for the electronic financial payment device, it usually further includes a display 20 and a frame 30, and the capacitive touch screen 10 is sandwiched between the display 20 and the frame 30. In the present embodiment, the capacitive touch screen 10 further includes a detachment prevention flexible circuit 17, such as an FPC detachment prevention flat cable, and the detachment prevention flexible circuit 17 is attached to a surface of the privacy film 16 facing away from the lower glass substrate 12b and electrically connected to the touch control panel 2. Further, as shown in fig. 6, a plurality of detachment prevention points 171 are arranged at intervals on the detachment prevention flexible wiring 17, and when the capacitive touch screen 10 is in the compressed assembled state, the detachment prevention points 171 are in an electrically conductive state. Specifically, the anti-detaching point 171 includes an elastic conductive sheet, when the display 20 and the touch screen are in a normal tightly pressed state, the elastic conductive sheet is pressed by elasticity to be in a conducting state, and when the capacitive touch screen 10 of the device is detached from the display 20, the elastic conductive sheet will be bounced off, so that the circuit of the anti-detaching flexible circuit 17 is disconnected, and the touch control board 2 senses the disconnection information and then completely deletes the sensitive information, so that the back of the capacitive touch screen 10 can be prevented from being additionally implanted with a PIN monitoring device by tightly pressing the display 20 and the capacitive touch screen 10. However, the design is not limited thereto, in other embodiments, the detachment prevention point 171 may also use a micro pressure sensor or the like to perform a detachment alarm function by detecting a pressure change, but the elastic conductive sheet in this embodiment has the advantages of simple structure, small volume, low cost, and the like.
Further, the back of the touch screen body 1 is further provided with a detachment detection switch 4, the detachment detection switch 4 may be connected with the detachment prevention flexible circuit 17 as shown in this embodiment, or may be separately electrically connected with the touch control panel 2, and the detachment detection switch 4 is preferably disposed adjacent to the edges of the display 20 and the capacitive touch screen 10. Similarly, when the capacitive touch screen 10 and the display 20 are in a pressed assembled state, the detachment detection switch 4 is in an electrically conductive state, and when the capacitive touch screen 10 and the display 20 of the device are detached, the circuit of the detachment detection switch 4 is immediately disconnected, so that the touch control panel 2 is prompted to immediately and completely delete the sensitive information.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
