Housing Structure, Display Module, and Electronic Device

原文（中国語）

This disclosure provides a housing structure, a display module, and an electronic device. The housing structure can improve scratch resistance of cover plate glass. When the housing structure is applied to a 3D curved display panel, there is no appearance color difference in a 3D cambered display area. The housing structure includes a substrate and a scratch-resistant layer located on a side of the substrate. The scratch-resistant layer includes at least two materials, and the at least two materials include at least one high refractive index material and at least one low refractive index material. The scratch-resistant layer has a thickness greater than or equal to 300 nm and less than or equal to 5000 nm. The low refractive index material has a refractive index less than or equal to a refractive index of the substrate, and the high refractive index material has a refractive index greater than 1.6.
