Claim 9:
10. A method for manufacturing a display panel, comprising:
providing a base substrate;
forming a signal noise sensor on the base substrate, the signal noise sensor being configured to detect a signal noise from the display panel; and
forming a touch sensor on a same layer as the signal noise sensor, or forming a touch sensor on a side of the signal noise sensor away from the base substrate,
wherein the display panel comprises a plurality of dummy patterns, the signal noise sensor comprises a plurality of noise detection electrodes, and the forming the signal noise sensor on the base substrate comprises forming the plurality of dummy patterns and the plurality of noise detection electrodes through a single patterning process,
wherein all of the plurality of noise detection electrodes are electrically connected to each other,
an outer contour of at least one noise detection electrode is located within an outer contour of at least one touch sub-electrode,
the plurality of dummy patterns is electrically insulated from each other, and each dummy pattern is electrically insulated from the noise detection electrodes,
each touch sub-electrode comprises a receiving electrode and a transmitting electrode,
an extension direction of each bridging line crosses an arrangement direction of the receiving electrode and the transmitting electrode,
the noise detection electrode and the dummy pattern have a same size and a same shape,
the noise detection electrodes are arranged directly on both the receiving electrode and the transmitting electrode.
