The change curve of the compressive stress and tensile stress of the strengthened glass meets a specific function relationship; within the range of 0.45-0.85 mm, the stress distribution meets the following condition: the stress curve is within the following Log-PI function range, the upper limit Fmax of the compressive stress meets the formula (1): Fmax=b+(2*a/PI)*(w/(4*(x−c){circumflex over ( )}2+w{circumflex over ( )}2)), and the lower limit Fmin of the compressive stress meets the formula (2): Fmin=b+(2*a/PI)*(w/(4*(x−c){circumflex over ( )}2+w{circumflex over ( )}2)); or the chemically strengthened glass comprises a first stress region and a second stress region, wherein the stress range of a first subregion in the first stress region includes that the minimum value of the stress difference value of the glass thickness t in the region of 0-10 micrometers is greater than 1 Mpa; and the pressure difference value of the second stress region is smaller than that of the first stress region. The deep compressive stress region of the strengthened glass has relatively high stress, and the tensile stress region has very-low-degree variation amplitude, so that the glass has excellent mechanical strength, very high stability and very high safety. | 05-05-2022 |
