The longitudinal array substrate test traces and the horizontal metal traces at the edge of the display area are always vertically staggered. In the box test project, the staggered positional relationship causes the lateral display signals to be affected by the coupling, causing Display differences on the left and right sides of the display panel; in addition, leakage may occur in staggered positions, and even abnormal problems such as damage may occur, which may affect the yield of the display panel.
