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.

Abstract: The present application provides a manufacturing method of an array substrate, an array substrate, and a display panel. The manufacturing method of the array substrate includes providing a base substrate; forming a conductive layer and a photoresist layer on the base substrate; patterning the photoresist layer and the conductive layer to form a conductive area and an electroplating area electrically connected to each other; removing the photoresist layer; forming an electroplating layer; and disconnecting the electroplating area from the conductive area. In the present application, the photoresist layer has a less thickness to reduce manufacturing costs of the array substrate.
