Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
The liquid crystal touch screen that the present embodiment provides a kind of anti-penetration to attack, comprise liquid crystal touch screen, described liquid crystal touch screen is provided with N number of wire loop, during in order to this wire loop open circuit, trigger an alarming mechanism because of the change in electric of this wire loop, described N is natural number.
As shown in Figure 1, in the present embodiment, described liquid crystal touch screen comprises a substrate 1(glass substrate); One arranges touch-control loop layer 2 on the substrate, refers to Fig. 2, and this touch-control loop layer comprises the X induction line 211, second be cascading and protects insulation course 212, Y induction line 213 and the first protection insulation course 214; Described X induction line 211 and Y induction line 213 are connected to the control circuit of system by flexible printed circuit board 8, and in the present embodiment, this system can be a POS terminal, and the control integration IC7 of a touch-control loop layer arranges with on described flexible printed circuit board; One photosynthetic glue 6 arranges the top with described touch-control loop layer 2; One transparent glasses lens 4 is located at above described photosynthetic glue, and the periphery of this transparent glasses lens is printed with the region 5 of black ink for screen printing.The present invention by arranging N number of wire loop in this liquid crystal touch screen, and we are for 1 wire loop here, are noted that the number of wire loop of the present invention can set as required.Continue referring to Fig. 1, in the present embodiment, described wire loop can be arranged at all sides (as shown in Figure 1, Figure 2 and Figure 3) of X induction line 211 on the touch-control loop layer of liquid crystal touch screen and Y induction line 213, also can cover on described touch-control loop layer (not illustrating in this structural drawing), it is worth mentioning that, this liquid crystal touch screen is existing touch screen, be not limited with said structure, this wire loop can be made up of thin plain conductor, also can be that printing conductive material is made, in the present embodiment, this wire loop adopts printing conductive material to make.This conductive material can have conducting metal (such as molybdenum aluminium molybdenum), also can have conducting metal oxide (as tin indium oxide).According to the different requirements of product size, the width of printed circuit cable can be 2.6um to 2540um; According to different process during production and processing, thickness can be that 25nm is to 70 um.If adopt multiple wire loop, then the conductor spacing between each loop can be 2.6um to 2540um.In an embodiment of the present invention, when lawless person intention penetrate touch-screen attack time, destroy touch-screen, then described wire loop is destroyed, the change in electric of wire loop and trigger an alarming mechanism, this alarming mechanism can be a warning circuit, also can be the control CPU10(of system as shown in Figure 6, here this CPU is arranged on the mainboard 9 of POS terminal), when CPU10 recognizes this trigger pip, then start alarm, such as, send alert song, auto dialing or send short message to relevant responsible official etc.
It is worth mentioning that, wire loop of the present invention is not only confined to be arranged on the layer of touch-control loop, it can also be arranged on the lower surface of whole liquid crystal touch screen (as shown in Figure 4, the first end 31 of this wire loop and the second end 32 are connected to an alarming mechanism), the wiring of this coil can be the periphery of liquid crystal touch screen, also can be the snakelike or irregular lower surface (as shown in Figure 5 and Figure 6) being laid in liquid crystal touch screen.
Generally speaking, the present invention is by arranging wire loop on the touchscreen, and the position that this wire loop is arranged does not have specific restriction, and above-mentioned is only several examples of implementation of the present invention; When touch-screen is destroyed, then this wire loop also can be destroyed, thus causes the level in wire loop to change, trigger alerts.By this simple method, make this touch-screen inherently a kind of protection device, decrease the parts that traditional anti-penetration is attacked, reduce costs, improve the reliability of system.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
