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.

Abstract: The present disclosure provides an organic light-emitting diode display substrate and a manufacturing method thereof. The manufacturing method includes: sequentially forming a first electrode, a light-emitting layer and a second electrode on a base substrate; forming a protection layer having a first opening on a side of the second electrode distal to the base substrate; and forming a second opening in the second electrode, the second opening being located below the first opening. In the present disclosure, with the protection layer, only a portion of the second electrode below the first opening is removed, so that other portions of the second electrode are prevented from being damaged, thereby eliminating a poor display of the display device.
