Abstract

The invention discloses a stretchable display panel and a display device, which belong to the field of display technology. The stretchable display panel includes a plurality of display islands and a plurality of stretchable bridges; the display island includes a first substrate and a second substrate arranged in layers. Two substrates; the making material of the first substrate has a first modulus of elasticity, the making material of the second substrate has a second modulus of elasticity, and the first modulus of elasticity is greater than the second modulus of elasticity; the stretchable bridge includes the first modulus of elasticity Three substrates, the third substrate is made of the same material as the second substrate. The display device includes the aforementioned stretchable display panel. The present invention is beneficial to improve the stretchability of the panel, and the laminated first substrate and the second substrate can make the display island meet the requirement of low deformation, avoid affecting the display function of the display device on the display island, and can also avoid stretching During the process, film layer peeling occurs at the junction of the stretchable bridge and the display island, which is beneficial to improve the reliability of the panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a stretchable display panel and a display device. Background technique [0002] With the development of the information society, various types of flat panel display devices have emerged, such as liquid crystal display panels, plasma display panels, and electrophoretic display panels. However, traditional display panels are made of rigid materials such as glass, and the size and shape of the display panels are fixed after production, which cannot be used in multiple occasions and complex environments. With the development of display technology, portable devices are gradually changing human life. Flexible display panels are favored by more and more portable device users due to their advantages of foldability, portability and wide application range. [0003] A stretchable flexible display screen disclosed in the prior art brings a brand-new viewing experience to u...
