[0001] The utility model belongs to the technical field of glass testing, and in particular relates to a device for detecting the flexibility of ultra-thin glass. Background Art
[0002] With rising living standards, demand for electronic displays is shifting towards thinner, smarter, and more flexible devices. This is particularly true for the recent surge in popularity of wearable electronics, foldable smartphones, and highly realistic curved display technologies, such as watches, 2.5D and 3D mobile phones, foldable phones, flexible e-books, and curved TVs. These displays are placing new demands on the flexibility of the ultra-thin glass that underpins these displays. Glass with excellent hardness, transparency, heat resistance, electrical insulation, airtightness, and relatively stable mechanical and chemical properties is essential for its application in displays such as tablets, mobile phones, wearable devices, and automotive displays, making it an indispensable key material. As electronic displays become thinner, smarter, and more flexible, the demand for ultra-thin glass's flexibility is also increasing. Therefore, continuously exploring and optimizing testing methods and evaluation criteria for ultra-thin glass flexibility is crucial for advancing the development of electronic display technology.
[0003] Although traditional glass material mechanical property testing methods such as three-point and four-point bending methods and double-ring methods have been applied based on small deflection deformation, these methods are no longer accurate enough for characterizing the mechanical properties of ultra-thin glass, especially the flexibility of ultra-thin glass. Therefore, there is an urgent need for a testing method and corresponding device that can set multiple conditions to improve the testing efficiency and accuracy of ultra-thin glass flexibility, so as to select ultra-thin glass products with superior flexibility to meet the processing and use requirements of the products.
