Projected position on plate 10 is array base palte 10 and abnormal position occurs.In actual applications, can by processing module 40 with
Display screen is connected, so that the position of the electrode portion 21 for producing aberrant electrical signals is shown by way of showing, in order to testing staff
Judge the out-of-the way position on array base palte 10.
Generally, occur on array base palte 10 that abnormal region is less, also, in the electrode portion 21 corresponding to out-of-the way position
The signal of telecommunication differs larger with the signal of telecommunication in the electrode portion 21 corresponding to normal position.Therefore, when electrode portion 21 total quantity compared with
When many, the standard electric range of signal can be configured according to the signal of telecommunication in each electrode portion 21.Specifically, processing module
40 are additionally operable to obtain meansigma methodss v0 of each signal of telecommunication measured by detection module 30 and corresponding with the array base palte default
Undulating value Δ v, and by [v0- Δ v, v0+ Δ v] as standard electric range of signal.Wherein, the default undulating value can be according to battle array
The particular type of row substrate 10, structure, size etc. pre-set.
Shown in Fig. 3 is the number of the electrode portion 21 according to corresponding to the different electrical signals value of 21 power on signal of electrode portion fitting
Magnitude relation schematic diagram；Wherein, abscissa represents the value of the signal of telecommunication in electrode portion 21, and vertical coordinate is corresponding to each signal of telecommunication
The quantity of electrode portion 21, it can be seen that the curve distribution is about the quantity of the electrode portion 21 of v0 most into normal distribution, value of electrical signals
It is many, scope of the signal of telecommunication in the electrode portion 21 of a minority part beyond [v0- Δ v, v0+ Δ v].When in each electrode portion 21
The signal of telecommunication in the range of [v0- Δ v, v0+ Δ v], then show that array base palte 10 does not occur exception,
The present invention is not construed as limiting to the shape of electrode portion 21, can be strip or bulk.As shown in Fig. 2 electrode portion 21 is
Bulk, electrode portion 21 are arranged as multiple lines and multiple rows, in order to detect all positions of array base palte 10.
When electrode block 21 is larger, it is determined that being after which electrode block produces abnormal signal, it may be determined that on array base palte
Region corresponding with abnormal electrode block produces exception, but remains a need for further detecting to be which or which pixel cell is produced
It is abnormal.In order to improve accuracy of detection and detection efficiency, it is preferable that each electrode portion 21 with the array base palte 10 to be detected
1～100 pixel cell correspondence, in order to quickly detect abnormal specific position.
As depicted in figs. 1 and 2, battery lead plate 20 can also include dielectric base 22, and electrode portion 21 is arranged on dielectric base 22
On, in order to move while multiple electrodes portion 21, consequently facilitating producing between multiple electrodes portion 21 and array base palte 10 identical
Interval.
