The electro-static discharging generator carries out the electrostatic discharge testing that n times discharge capacity is E to the point to be detected in first output；
After measuring point electrostatic discharge testing n times to be checked of the gating module in first output channel, the gating mould
Block gates next output channel as current output channel, and the electro-static discharging generator is to be checked in current output channel
Measuring point carries out n times discharge capacity and is E electrostatic discharge testing, until the measuring point to be checked being connected with each output channel to be detected is all complete
During into n times static discharge, terminate this electrostatic discharge testing of the display panel.
8. the method as described in claim any one of 5-7, it is characterised in that the electro-static discharging generator is provided with display mould
Block；
Correspondingly, before described this electrostatic discharge testing for terminating the display panel, methods described also includes：
The gating module numbers currently selected logical output channel when the electrostatic discharge testing of the display panel interrupts
Feed back to the display module；
The display module receives the currently selected logical output channel numbering, and to the currently selected logical output channel
Numbering is shown.
