Abstract

The invention discloses a method of assessing electro-static discharge (ESD) sensitivity of flat panel display (FPD) product in manufacture. The method comprises the following steps of: A, establishing an electronic device structure simulation model of an FPD product in a front-end manufacturing process; B, establishing an ESD failure condition simulation model in the front end manufacturing process of the FPD product according to the simulation model in the step A; and C, establishing an ESD failure sensitivity test method in the front end manufacturing process of the FPD product according tothe simulation model in the step B. With the adoption of the method and the device, an FPD manufacturing factory can master the ESD sensitivity degree of the FPD product of the FPD manufacturing factory, and reasonable electrostatic protection planning design can be performed in the factory according to the ESD sensitivity degree, so that an effective electrostatic protection target in an FPD product production and manufacturing stage is realized.

Description

technical field [0001] The flat panel of the invention relates to the field of display technology, in particular to a method for evaluating the electrostatic discharge sensitivity of flat panel display products during manufacture. Background technique [0002] In the flat panel display (FPD, Flat Panel Display) product manufacturing industry, there is no publicly released method suitable for evaluating the ESD (Electro-Static Discharge, electrostatic discharge) sensitivity method in the manufacturing stage of flat panel display products, so that each flat panel display When manufacturing enterprises carry out electrostatic protection in the production stage of the factory, the method design and implementation of electrostatic protection measures that cannot be realized can provide effective and appropriate electrostatic failure prevention protection for flat panel display products. attached Figure 4 , 5 , 6, and 7 are currently the representative main technical implementat...
