Tempered glass for preventing generation of rainbow pattern and manufacturing method thereof

Abstract

A tempered glass for preventing generation of a rainbow pattern and a manufacturing method thereof are provided. The tempered glass for preventing generation of the rainbow pattern is prepared by compounding a protective layer and an ultra-low phase-difference substrate layer. A compounding process is introduced in the manufacturing method to allow the synchronous stretching of a plurality of layers. In the tempered glass, a substrate layer with an ultra-low phase difference in terms of a polarization angle from a polarizer is arranged, such that a user can well view a screen of an electronic product in various scenarios, and a content of a screen will not undergo rainbow patterns or color differences due to different scenarios and conditions. A material used for the tempered glass has a high light transmittance, a low haze, a high deformation rate, and a high resilience rate to allow ultra-high performance.
