Abstract

Embodiments of the present invention provide a stretchable display panel and a stretchable display device, which relate to the field of display technology and improve the warping phenomenon of the stretchable display panel. The stretchable display panel includes: a stretchable substrate, the stretchable substrate is composed of an island structure and a bridge structure, and two adjacent island structures are connected by a bridge structure; the island structure includes a first carrier substrate and a bridge structure. The first display film layer, the first display film layer includes pixel units, the bridge structure includes a second carrier substrate and the second display film layer, the second display film layer includes signal lines; the bridge structure has a first section, the first section Vertical to the plane where the second carrier substrate is located, and the first section is perpendicular to the extension direction of the bridge-like structure, the maximum width of the first section in the first direction is W1, and the maximum thickness of the bridge-shaped structure in the direction perpendicular to the plane where the second carrier substrate is located H1, H1≥W1, the first direction is parallel to the plane where the second carrier substrate is located, and is perpendicular to the extending direction of the bridge-shaped structure.

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...
