Abstract

The invention provides a stretchable display panel and a display device. The stretchable display panel comprises a middle display area, a transition display area and a wiring area, in the direction from the middle display area to the wiring area, the width of a bridge structure in the transition display area is gradually increased, and the tensile strength of the bridge structure is in direct proportion to the width of the bridge structure, so that the tensile strength of the bridge structure in the transition display area is gradually increased in the direction from the middle display area to the wiring area, and the tensile strength and the tensile resistance of the transition display area are enhanced while the tensile property of the display area is guaranteed. An island structure located on the periphery comprises at least one edge bridge structure used for connecting the island structures and the wiring area. The tensile strength of the edge bridge structures is improved by increasing the width of the edge bridge structure in a mode that the adjacent edge bridge structures intersect, the situation that the edge bridge structures are broken due to local stress generated on the side, close to the wiring area, of the transition display area is avoided, and therefore the risk that wiring of the transition display area is broken is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a stretchable display panel and a display device. Background technique [0002] With the development of flexible organic light emitting diode (OLED) display technology, the consumer market for folding and scrolling display terminal products is gradually released and matures. The innovation of folding display technology has enriched the widescreen design direction of mobile phones, tablets, and notebook computers, and the display functions and effects are more experienced than liquid crystal display technology. On the basis of flexible OLED display technology, stretchable display technology will be the key research direction of next-generation display technology. [0003] The essence of stretchable display technology is to realize the flexibility of the screen itself. Through the flexible design of the display backplane, that is, the method of pattern design, the backp...
