US Patent 11282914 Organic light-emitting diode display panel and display device

The invention provides an organic light-emitting diode (OLED) display panel and a display device. Metal wiring is designed into a first metal layer and a second metal layer. The first metal layer is distributed on an edge of a display area and a bending area, the second metal layer is positioned in the bending area, and the second metal layer is disposed opposite to the first metal layer. A part of the first metal layer positioned in the bending area is electrically connected in parallel or in series with the second metal layer to form a double-layer wiring or a double-layer wiring exchange structure. After any one of the metal layers breaks, the other metal layer can still be used to maintain signal transmission.
