Claim 16:
17. A method for manufacturing a display panel, comprising:
providing a display substrate; the display substrate having a display area and a frame area located on a side of the display area, and the frame area including a bonding region;
forming a touch structure on the display substrate, the touch structure including a plurality of conductive pins located in the bonding region;
forming a protective film on a side of the touch structure away from the display substrate; and
patterning the protective film to form a protective layer; wherein the protective layer has an opening, the opening is located in the bonding region and serves to expose the plurality of conductive pins, and the opening includes a border proximate to the display area and extending in a direction in which the plurality of conductive pins are arranged, and at least portion of the border has a curved shape; wherein
forming the touch structure on the display substrate comprises:
providing a base;
forming a first conductive film on a side of the base;
patterning a portion of the first conductive film located in the display area to form a plurality of first touch units and a plurality of second touch electrodes of each second touch unit;
forming an insulating layer on a side of the plurality of first touch units and the plurality of second touch electrodes of each second touch unit away from the base;
forming a second conductive film on a side of the insulating layer away from the base;
patterning a portion of the second conductive film located in the display area to form a plurality of conductive bridges, processing a portion of the second conductive film located in the frame area and a portion of the first conductive film located in the frame area, so as to form a plurality of touch signal lines located in the frame area and the plurality of conductive pins located in the bonding region to obtain the touch structure; and
providing a connection layer to connect the base and the display substrate together and to make the touch structure be located on a side of the base away from the display substrate.
