Abstract

The embodiment of the present application discloses a stretchable display module and a stretchable display device. The stretchable display module includes a display area and a non-display area arranged around the display area. The display area includes a main display area and is arranged on the main display area. The edge display area between the display area and the non-display area, the stretchable display module includes a plurality of pixel islands and a plurality of connecting bridges, a plurality of pixel island arrays are distributed in the display area, and each pixel island is provided with at least one pixel , each connecting bridge connects two adjacent pixel islands in the main display area, an opening group is arranged between the adjacent pixel islands in the edge display area, and the opening group includes an arrangement from the edge display area to the non-display area and the area gradually decreases of multiple openings. On the one hand, the stretchable display module provided by the embodiments of the present application can enhance the rigidity of the edge display area to prevent the area from being subjected to excessive strain, and on the other hand, it can also avoid wrinkles in the edge display area, especially the edge display can be avoided. The four corners of the area are wrinkled.

Description

technical field [0001] The present application relates to the field of display, in particular to a stretchable display module and a stretchable display device. Background technique [0002] Scalable and flexible OLED (Organic Light-Emitting Diode, organic light-emitting diode) display technology is a flexible display technology that combines inorganic electronic display devices and flexible structured substrate materials through inorganic film transfer methods to achieve arbitrary deformation of the screen. Scalable flexible display technology will have broad application prospects in medical, human-computer interaction, vehicle display and other fields. Among them, the mechanical study of the flexible structure design of the base material is an important part of the flexible display technology. [0003] It should be noted that the malleable display screen will inevitably be subjected to complex external forces such as stretching, torsion, and bending during use. The displa...
