A preparation method for curved glass, comprising:
- melting a glass batch into a glass liquid, and clearing the glass liquid;
- introducing the cleared glass liquid into a mold cavity of a mold with a preset shape, and forming, by using a compression molding process, a molded glass product with a shape corresponding to that of the curved glass, wherein a size of the molded glass product is greater than a size of the curved glass, and wherein a difference between the size of the molded glass product and the size of the curved glass is greater than or equal to 0.02 mm and less than or equal to 0.5 mm;
- annealing the molded glass product;
- and
- processing the annealed glass product into the curved glass based on the shape and the size of the curved glass.
