Abstract: A flexible substrate has at least one bendable region. The flexible substrate includes a flexible base, a first electrode layer disposed on the base, a first insulating layer disposed on a side of the first electrode layer away from the base, and a second electrode layer disposed on a side of the first insulating layer away from the base. The first electrode layer includes at least one first detection electrode, and the second electrode layer includes at least one second detection electrode. An orthogonal projection of a first detection electrode on the base overlaps at least partially with an orthogonal projection of a second detection electrode on the base. A region where orthogonal projections of the first detection electrode and the second detection electrode on the base are located overlaps with a bendable region.
