Liquid crystal screen safety disassembling prevention structure and method

Abstract

The invention provides a liquid crystal screen safety disassembling prevention structure and method. A safety line is etched at the edge position of a liquid crystal screen, is led out by a FPC and extends to a limiting structure; the FPC is fixed by the limiting structure and a zebra bar together so as to enable the FPC to be in a tightened state; edge glass of the liquid crystal screen is used as one part of the safety disassembling prevention structure; the edge glass of the liquid crystal screen is relatively weak and the edge glass of the liquid crystal screen is easy to damage in the disassembling process to trigger a safety mechanism, and thus, the FPC is fixed by the limiting structure and the zebra bar together so as to enable the FPC to be in the tightened state, and in a case ofnot damaging the FPC, even though the liquid crystal screen safety disassembling prevention structure is known, the liquid crystal screen also cannot be disassembled from the front side; and the FPCis in the tightened state, and thus, when liquid crystals are tried to be taken out, breakage of the FPC can be caused to trigger the safety mechanism, so that the disassembling difficulty is improved; and resistance values for the zebra bar to access a circuit are different under the action of different pressures, so that safety is higher.

Description

technical field [0001] The invention relates to the technical field of safety and anti-dismantlement, in particular to a liquid crystal screen safety and anti-dismantlement structure and method. Background technique [0002] With the development of the public's mobile payment habits, password security has become an eternal pursuit in the financial industry. As far as password security is concerned, it is divided into two parts: one is for user password security, and the other is for banking system and POS machine security. Based on realistic needs, various POS manufacturers have never stopped exploring in the security field. With the popularity of large-screen POS machines, the security protection of POS screens has become an important issue. [0003] There are two main methods for the safety and anti-disassembly of the existing LCD screen. One is to firmly fix the LCD screen and the structural parts on the back of the fuselage, such as using special glue to fix it, or to ...

Problems solved by technology

[0003] There are two main methods for the safety and anti-disassembly of the existing LCD screen. One is to firmly fix the LCD screen and the structural parts on the back of the fuselage, such as using special glue to fix it, or to install the LCD screen from the inside out to prevent illegal users from dismantling it. The LCD screen detects internal signals; the other is to attach the FPC to the LCD screen, which may destroy the FPC when the LCD screen is removed, and trigger a safety mechanism to protect the LCD screen and touch screen, but the above two methods have certain shortcomings , the former can forcibly peel off the LCD screen from the structural parts to detect internal signals; the latter, after knowing the installation method of the screen, can peel off the corresponding FPC through high-temperature baking to detect internal signals, so a more Safe tamper-resistant structure
