Claim 26:
27. A display device, comprising a display panel comprising a display area and a non-display area, wherein:
the display panel includes:
a plurality of first subpixels on the substrate, wherein:
a first subpixel of the plurality of first subpixels includes a first pixel circuit and a light-emitting element electrically connected to the first pixel circuit,
the first pixel circuit at least includes a first type of double-gate transistor, a first gate of the first type of double-gate transistor is connected to a first control line, and a second gate of the first type of double-gate transistor is connected to a second control line,
in the display area, the first control line and the second control line are disposed on different layers, and a film layer where the second control line is located is on a side of a film layer where the first control line is located away from the substrate,
at least part of an orthographic projection of the first control line corresponding to the first type of double-gate transistor on the substrate at least overlaps part of an orthographic projection of the second control line on the substrate; and

a second detection line having a same width as the second control line.
