  • Patent number: 10366645
    Abstract: The present disclosure provides a lighting-on device and a method for cell test. The lighting-on device includes a movable unit including a first marker; an image acquisition unit configured to acquire an image indicating an actual relative positional relationship between the first marker and a second marker on a display panel; a calculation unit configured to calculate the actual relative positional relationship between the first marker and the second marker according to the image; a first position adjustment unit configured to drive the movable unit so as to adjust the actual relative positional relationship; and a first control unit configured to determine whether the adjusted actual relative positional relationship has been aligned by the first position adjustment unit according to the relative positional relationship between the first marker and the second marker.
