Description
Technical field
It the utility model is related to a kind of multi-functional touch-screen.
Background technology
In today that information development is swift and violent, various electronic equipments are meeting daily life；Bankcard consumption or barcode scanning
Consumption has been substituted traditional cash transaction, and POS is just into the indispensable equipment of process of exchange.POS was more in recent years
The new replacement is more and more faster, and the technical merit of equipment is uneven, and the security of equipment makes people worried.Many equipment vendors get
The function of " it is destroyed to tear machine open ", but the actual case that brush bank card is still stolen with the presence of many repacking POSs.
The POS with touch-screen is popularized quickly at present, anti-tamper for how to be done on the touch-control display unit of slave unit
Function, still belong to clear area at present.
Utility model content
The purpose of this utility model is to provide a kind of touch-screen with anti-tamper circuit, improves and set the touch-screen
The security of the terminal such as POS or similar swiping card equipment.To solve above technical problem, technical scheme provided by the utility model
It is：
A kind of touch-screen with anti-tamper circuit, is provided with anti-tamper circuit, it is characterised in that the anti-tamper sets of lines
Into on the touchscreen, on anti-tamper connection to control chip.
The touch-screen includes cover plate and touch sensing；The anti-tamper circuit sets on the cover board or is arranged on touch-control
On sensor.
Further, the anti-tamper circuit can be set on the cover board, and the anti-tamper circuit is arranged on the four of cover plate
Week, and leave contact point in the end of circuit and be connected with control chip, loop is formed with combination.
Further, the anti-tamper circuit is arranged on the surrounding decorative ink surface of cover plate, is setting anti-tamper circuit
Before, first in cover plate perimeter printed decoration ink, front can not see the circuit after being installed with guarantee.Cover plate can be glass or modeling
Expect material.
Further, the cover plate with anti-tamper circuit is bonded with connecting the inductor of FPC, and formation one is complete
The whole touch-screen with anti-tamper function.
Equally, the anti-tamper circuit can also be integrated on the touch sensing of touch-screen, and touch sensing can be
Glass tactility apparatus, film sensors.The touch sensing carries touch-control sensing circuit.The anti-tamper circuit and touch sensing
On touch inductive circuit production order without priority divide；The substrate of touch sensing can be glass or plastic material.
The anti-tamper circuit is arranged on the surrounding of touch sensing and is in that side that touch sensing substrate deviates from cover plate, and
The end of circuit is left contact point and is connected with control chip, and loop is formed with combination.
Further, the touch sensing with anti-tamper circuit is first connected after completing with FPC, then with
Cover plate patch patch, composition one completely carry the touch-screen of anti-tamper function.
The anti-tamper circuit is connected by control chip interface on FPC, shell fragment or conductive rubber mode and mainboard
Connect.
The anti-tamper circuit is circuit with conducting function, being completed by printing, plated film, etch process,
It is arranged on cover plate or touch sensing, and leaves contact point in the end of circuit and be connected with control chip.
Touch-screen belongs to the external component of equipment, if dismounting assembling, can remove the position first, the utility model can be with
Whether simple and effective inspection touch control display module is disassembled or shifts." torn open once detecting and being disassembled or shift to start
Machine is destroyed " function, it can prevent from being mounted with the POS of this touch-screen or be dismounted similar to swiping card equipment to distort.
So-called " it is destroyed to tear machine open " not damages equipment, but once generation touch-screen separates with equipment or touch-screen is damaged
Caused loop disconnects, and connects the control chip of anti-tamper circuit in real time and will can not arrive signal by the anti-tamper circuit transmitting-receiving
Or signal interruption, the confidential data preserved so as to the presetting functional module of trigger control chip, auto-erasing equipment.
