Abstract: The present invention provides an array base plate and a manufacturing method therefor. The array base plate includes a substrate base plate layer, a first trace layer, an insulating layer, and a stress balance layer. The first trace layer includes a first trace. An edge of the stress balance layer is aligned to an edge of the substrate base plate layer. The stress balance layer has a bending stress in a direction opposite to a direction of the first trace and a curvature less than 1.2 mm/m.

Abstract: The present invention relates to a backlight module and a preparation method therefor, and a display panel. According to the present invention, solid white ink is attached to a second base plate, and then the solid white ink corresponding to positions of bonding pad units is removed by means of laser engraving, so as to prevent the screen-printing white ink from damaging the second base plate. Aligned assembling is performed on a first assembly and a second assembly using a vacuum pairing device. The vacuum pairing device may be reused in other preparation processes of the display panel. Therefore, the device investment can be reduced, and the production costs can be lowered.
