Problems solved by technology

[0003] However, the inventors of the present invention have found that about 10%-20% tensile strain is required to stretch the plane into a semicircular arc, and up to 57% tensile strain is required to stretch into a hemispherical shape; The screen area of ​​the stretched display screen is greatly increased, and the density of the pixel units set on the screen for display is reduced, resulting in a decrease in the display brightness of the screen body

Abstract

The invention discloses a stretchable display panel and a display device, and relates to the technical field of display. The stretchable display panel comprises a flexible substrate and light emittingpixel units arranged thereon, each light emitting pixel unit comprises a top side far from the flexible substrate, the top sides of the light emitting pixel units form a light emitting surface towards the light output side of the stretchable display panel, the side, close to the flexible substrate, of the light output side is provided with a compensating light emission unit, the compensating light emission unit is hidden in the side close to the flexible substrate of the light output side when the flexible substrate is not stretched, and the compensating light emission unit is exposed to thelight emission side when the flexible substrate is stretched. The stretchable display panel and display device have the advantage that the brightness is not changed during stretching.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular 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 devices, plasma display devices, and electrophoretic display devices. However, traditional display devices are made of rigid materials such as glass, and the size and shape of the display devices are fixed after production, which cannot be used in multiple occasions and complex environments. Therefore, people have been focusing on the research of flexible and stretchable display devices for many years. Until 2017, the world's first stretchable display device based on AMOLED appeared. The screen body of this stretchable display device can achieve a certain angle. of bending and stretching without damage. [0003] However, the inventors of...
