Patent attributes
A display may have an array of organic light-emitting diodes that form an active area on a flexible substrate. Metal traces may extend between the active area and an inactive area of the flexible substrate. Display driver circuitry such as a display driver integrated circuit may be coupled to the inactive area. The metal traces may extend across a bent region in the flexible substrate. A coating layer in the bent region may serve as a neutral stress plane adjustment layer. Metal traces may have meandering shapes such as zigzag shapes to reduce stress when bending. Adjacent traces may be shorted together to provide redundancy. Multiple layers of traces may be provided. Inorganic passivation layer coatings on the metal traces may help protect the metal traces.
