Abstract: The present disclosure relates to a driving substrate, a manufacturing method, and a micro-LED array substrate light-emitting backlight module. The driving substrate includes a first metal layer, a first high-reflection layer, and a second metal layer stacked in a top-down sequence. The driving substrate, the manufacturing method, and the micro-LED array light emitting backlight module of the present disclosure solve the loss of reflectivity issue caused by the edge forbidden area of the electrode welding pad edge forbidden region. At the same time, the limited reflectivity of traditional coated high-reflective layers (such as white oil) may also be enhanced.
