Otherwise, if display panel testing 1 is found the AMOLED panel that do not have to detect further or is received stop order, with regard to detection of end.
So, according to embodiments of the invention, adopt multiple passage for the supporting plate 200 detecting small-sized AMOLED panel according to the large I of detected object, therefore there is reduction detection time, and be applicable to the effect of batch production.
And, utilize the pilot pin being located at the bottom of fixture 230 that contact element 240 is installed, thus contact element 240 can be arranged on correct position, and there is the effect simply can replacing contact element 240 when tested surface template number changes.
In addition, different from existing cartridge type mounting structure, when there is no physical contact, AMOLED panel is placed in panel bed 290, and makes from top contact element 240 contact, thus have and prevent AMOLED panel in testing process from producing the effect in crack.
