This utility model relates to a kind of liquid crystal display screen tamper design structure, including pcb board and liquid crystal display screen, described liquid crystal display screen is electrically connected with pcb board by FPC plate, described FPC plate is bonding with liquid crystal display screen back by adhesive layer, it is laid with sensitive signal cabling in described FPC plate, described FPC backboard portion is provided with two sensitive signals being electrically connected with sensitive signal cabling two ends respectively and accesses pad, being provided with two sensitive signals on described pcb board and draw pad, described sensitive signal is accessed pad and is conducted with corresponding sensitive signal extraction pad by conduction zebra bar.When this utility model uses, once liquid crystal display screen is split, FPC plate is followed split, sensitive signal disconnects, trigger and report to the police, play the effect preventing liquid crystal split, solve the difficult problem requiring in the electronic product of the financial field such as POS, code keypad that liquid crystal possesses tamper design, there is modern design, simple in construction, the advantage that easy to make, cost is relatively low and safe and reliable.
Description
Technical field
This utility model relates to liquid crystal display screen tamper technical field, especially a kind of liquid crystal display screen tamper design structure.
Background technology
At present; in the financial security such as financial transaction, E-Payment field; electronic product such as POS, code keypad and other finance device are in order to prevent accounts information to be stolen; the liquid crystal design requiring these equipment possesses the liquid crystal display screen function by strict protection; i.e. require to possess tamper function in liquid crystal design, and existing tamper design structure is complicated, make trouble and cost is high.
Utility model content
In view of the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of modern design, simple in construction, the liquid crystal display screen tamper that easy to make, cost is relatively low and safe and reliable design structure.
In order to solve the problems referred to above, the technical solution of the utility model is: a kind of liquid crystal display screen tamper design structure, including pcb board and liquid crystal display screen, described liquid crystal display screen is electrically connected with pcb board by FPC plate, described FPC plate is bonding with liquid crystal display screen back by adhesive layer, it is laid with sensitive signal cabling in described FPC plate, described FPC backboard portion is provided with two sensitive signals being electrically connected with sensitive signal cabling two ends respectively and accesses pad, it is provided with two sensitive signals on described pcb board and draws pad, described sensitive signal is accessed pad and is conducted with corresponding sensitive signal extraction pad by conduction zebra bar.
In further preferred version, described adhesive layer is arranged at the Zone Full that liquid crystal display screen coincides with FPC plate.
In further preferred version, described sensitive signal cabling is along the edge cincture of FPC plate.
In further preferred version, described sensitive signal accesses pad and is surrounded by sensitive signal cabling.
In further preferred version, described sensitive signal accesses pad and is positioned at the central authorities of sensitive signal cabling enclosing region.
Compared with prior art, when this utility model has the advantages that use, once liquid crystal display screen is split, FPC plate is followed split, sensitive signal disconnects, and triggers and reports to the police, plays the effect preventing liquid crystal split, solve the difficult problem requiring in the electronic product of the financial field such as POS, code keypad that liquid crystal display screen possesses tamper design, there is modern design, simple in construction, the advantage that easy to make, cost is relatively low and safe and reliable.

Detailed description of the invention
In order to allow features described above of the present utility model and advantage become apparent, special embodiment below, and coordinate accompanying drawing, it is described in detail below.
As shown in Fig. 1 ~ 3, a kind of liquid crystal display screen tamper design structure, including pcb board 300 and liquid crystal display screen 100, described liquid crystal display screen 100 is electrically connected with pcb board 300 by FPC plate 200, described FPC plate 200 is bonding with liquid crystal display screen 100 back by adhesive layer 400, it is laid with sensitive signal cabling 210 in described FPC plate 200, described FPC plate 200 back is provided with two sensitive signals being electrically connected with sensitive signal cabling 210 two ends respectively and accesses pad 220, it is provided with two sensitive signals on described pcb board 300 and draws pad 310, described sensitive signal is accessed pad 220 and is conducted with corresponding sensitive signal extraction pad 310 by conduction zebra bar 500.
In this utility model embodiment, relatively reliable in order to be adhesively fixed, described adhesive layer 400 is arranged at the Zone Full that liquid crystal display screen 100 coincides with FPC plate 200.
In this utility model embodiment, can not be cut off from any one face in order to ensure FPC plate 200, described sensitive signal cabling 210 is along FPC plate 200 edge cincture.
In this utility model embodiment, being shorted to prevent sensitive signal from accessing pad 220, described sensitive signal accesses pad 220 and is surrounded by sensitive signal cabling 210.Wherein, described sensitive signal accesses the position of pad 220 to be positioned at the central authorities of sensitive signal cabling 210 enclosing region most preferably.
Operation principle of the present utility model is as follows: when liquid crystal display screen 100 is started, and FPC plate 200 is taken up the most simultaneously, makes sensitive signal disconnect, and triggers and reports to the police, plays the effect preventing liquid crystal split.
This utility model is not limited to above-mentioned preferred forms, and anyone can show that under enlightenment of the present utility model other various forms of liquid crystal display screen tampers design structure.All impartial changes done according to this utility model claim and modification, all should belong to covering scope of the present utility model.
