Problems solved by technology

[0002] With the application of flexible OLED screens, foldable display panels have also emerged. However, during the production process, due to the stress generated when the foldable display panel is bent, it may cause the separation or fracture of its layers.
Foldable display panels in the prior art cannot visually detect cracks or defects in them, and if defective display panels are mass-produced, the yield rate of display panels will be reduced

Abstract

The invention discloses a foldable display panel. The display panel includes an effective area and an ineffective area arranged around the effective area. A deformation layer is arranged in the ineffective area of ​​the display panel; the material of the deformation layer is The force-induced strain material is included, so as to detect the deformation degree and crack defect of the display panel according to the light emission color and brightness of the force-induced strain material, so as to improve the mass production yield.

Description

technical field [0001] The present invention relates to the technical field of display panels, and in particular, to a foldable display panel. Background technique [0002] With the application of flexible OLED screens, foldable display panels have also emerged. However, during the production process, due to the stress generated when the foldable display panel is bent, it may cause separation or breakage between the layers. The foldable display panels in the prior art cannot visually detect cracks or defects therein, and if the defective display panels are mass-produced, the yield of the display panels will be reduced. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a foldable display panel, which can detect the degree of deformation and crack defects of the display panel through the emission color and brightness of the deformation layer, thereby improving the mass production yield. [0004] An embodiment of the present invention provides a ...
