Display device
View Patent ↗A display device is provided and includes a flexible display panel, a middle frame, and a stretching and folding assembly. The flexible display panel has a bendable area. The middle frame encompasses a periphery of the flexible display panel. The stretching and folding assembly is disposed in the bendable area and includes an elastic assembly, connecting blocks, and connecting pieces. The elastic assembly covers the bendable area and an area of the middle frame corresponding to the bendable area. The connecting blocks are disposed at two ends of the elastic assembly. Each connecting piece is disposed between two adjacent ones of the connecting blocks to connect the two adjacent ones of the connecting blocks and configured to cause the connecting blocks to drive, when the flexible display panel is bent, the area of the middle frame corresponding to the bendable area to be bent.
