If the lines on each picture overlap as shown in Figure 6A completely, represent the phenomenon that display interface is not shaken, therefore Test Host 102 judges the display interface normal (S240) of video card 20 to be measured, and the electric terminal 22,23,24 that the detection bodies of Test Host 102 presents video card 20 to be measured via test interface in display module 103 is normal (S245).
Relatively, if the lines on each picture do not overlap as shown in Figure 6B completely, or be the phenomenon that lines have overstriking, the lines that represent every image are slightly different and have a phenomenon of shake, therefore judge the display interface abnormal (S250) of video card 20 to be measured, and the electric terminal 22,23,24 that the detection bodies of Test Host 102 presents video card 20 to be measured via test interface in display module 103, for abnormal (S255), must carry out follow-up maintenance and carries out same test again or be directly judged as faulty materials.
So, in each detecting information that this enforcement can capture continuously by Test Host 102 comparisons and each demonstration information, whether the lines of each image overlap, whether each display interface of automatic decision video card 20 to be measured has the abnormal problems such as skew or jitter phenomenon, thereby as the first embodiment infers the whether fault of electric terminal 22,23,24 of each correspondence, and present by display module 103, note down for testing staff, or be automatically embedded in database by Test Host 102, check and keep in repair in order to follow-up, in order to follow-up adjustment with improve testing process.
