Abstract

The invention relates to a method for manufacturing a double-sided circuit substrate and a double-sided circuit substrate. The manufacturing method comprises the steps of providing a substrate, wherein the substrate comprises a first surface and a second surface, and the first surface and the second surface are opposite to each other; forming a first alignment mark and a first patterned circuit onthe first surface; sensing the position of the first alignment mark by using an optical positioning device; forming a second alignment mark on the second surface according to the position of the first alignment mark; sensing the position of the second alignment mark by using an optical positioning device; and forming a second patterned circuit on the second surface according to the position of the second alignment mark, wherein the second patterned circuit is aligned with the first patterned circuit in the normal direction of the substrate.

Description

technical field [0001] The invention relates to a method for manufacturing a circuit substrate, and in particular to a method for manufacturing a double-sided circuit substrate and the double-sided circuit substrate. Background technique [0002] The existing display device includes a display panel, the display panel includes a substrate, a plurality of pixel units and a plurality of edge elements, the substrate includes a display area and an edge area surrounding the display area, the pixel units are arranged in the display area, and the edge elements are arranged In the edge area, the edge element is further connected to the corresponding pixel unit, and the edge element can be used to drive the pixel unit or also be used as a ground circuit of the pixel unit. The display area of ​​the display panel can present images, while the edge area is a dark area and cannot present images. Therefore, the display device has a frame to cover the edge area and only expose the display ...
