Abstract

The embodiment of the invention provides a stretchable display panel and a stretchable display device, relates to the technical field of display, and improves the warping phenomenon of the stretchabledisplay panel. The stretchable display panel comprises a stretchable substrate, the stretchable substrate is composed of island-shaped structures and bridge-shaped structures, and every two adjacentisland-shaped structures are connected through the corresponding bridge-shaped structure; each island-shaped structure comprises a first bearing substrate and a first display film layer, each first display film layer comprises pixel units, each bridge-shaped structure comprises a second bearing substrate and a second display film layer, and each second display film layer comprises signal lines; each bridge-shaped structure has a first section perpendicular to the plane of the corresponding second bearing substrate, each first section is perpendicular to the extending direction of the corresponding bridge-shaped structure, the maximum width of each first section in the first direction is W1, the maximum thickness of each bridge-shaped structure in the direction perpendicular to the plane where the second bearing substrate is located is H1, H1 is larger than or equal to W1, and the first direction is parallel to the planes where the second bearing substrates are located and perpendicularto the extending direction of the bridge-shaped structures.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a stretchable display panel and a stretchable display device. 【Background technique】 [0002] In recent years, with the continuous development of flexible display technology, stretchable display panels have been gradually applied in fields such as wearable devices, Internet of Things devices, and artificial intelligence, bringing users a brand new viewing and use experience. [0003] In the prior art, stretchable display panels include pixel islands and stretch bridges, wherein two adjacent pixel islands are connected by stretch bridges, the pixel islands are used to carry display functional devices, and the stretch bridges are used to carry Signal traces that provide signals to display function devices. However, during the stretching process of the stretchable display panel, the stretching bridges tend to be bent and deformed in the light emitting direction of the display pa...
