Description

Technical Field

[0001] The invention relates to a variable radius bending jig and detection equipment thereof, belonging to the technical field of bending and curling detection. Background Art

[0002] Flexible displays are widely used in portable electronic devices due to their lightness, low power consumption, bendability and rollability. An important component of these devices is flexible screens and similar products that can be bent and rolled. Currently, most flexible screens on the market are bendable, and the bending angle is mostly 180°. Considering the needs of the diversity of mobile terminals in the market and the current development trend of mobile terminals, there are few devices for reliability testing of the bending performance of flexible screens.
