Abstract: Disclosed is a pixel circuit arranged in a display substrate, which comprises a first driving mode and a second driving mode. Content displayed in the display substrate comprises multiple display frames. In the first driving mode and the second driving mode, the display frames comprise refresh frames. A signal of a second scanning line is the same as that of a third scanning line. The time of which the signal of the second scanning line is an active level signal comprises a first refresh time period, a second refresh time period and a third refresh time period, which sequentially occur at intervals. During the second refresh time period, a signal of a first scanning line is an inactive level signal. The voltage of a signal at a reset voltage end is a positive voltage, and the voltage of a signal at a first initial voltage end is a negative voltage.

Abstract: An automatic optic inspection device and an inspection system for a display panel. The automatic optic inspection device includes: a housing including at least a top wall and a side wall, the side wall including a viewing port; a slide rail fixed on the housing near the top wall; and a camera slidably disposed below the slide rail. An optical axis of the camera passes through the viewing port. During the inspection, the camera is moved on the slide rails so that the camera is close to the stage of the lighting inspection machine and can perform automatic optic inspection of the display panel. When the automatic optic inspection device fails to inspect due to a fault, the camera can be moved along the slide rail so that the camera is moved away from the stage and manual inspection can take place while the inspection device is fixed.
