STRENGTHENED GLASS-BASED ARTICLES AND METHODS FOR REDUCING WARP IN STRENGTHENED GLASS-BASED ARTICLES

Strengthened glass substrates and methods of reducing warp in strengthened glass substrates having 3D and 2.5D shapes are disclosed. In one embodiment, a strengthened glass-based article includes a first surface, a second surface opposite the first surface, and an edge between the first surface and the second surface. The edge is asymmetric with respect to a plane that is located at an average depth of the strengthened glass-based article and is parallel to the first surface and the second surface. The strengthened glass-based article has an expected warp WE based at least in part on a shape of the asymmetric edge of the strengthened glass-based article. An actual warp WA of the strengthened glass-based article is less than 85 % of the expected warp metric WE of the strengthened glass-based article. The actual warp WA of the strengthened glass-based article is measured with a concave surface facing up. 公开了强化玻璃基材和减少具有3D和2.5D形状的强化玻璃基材中的翘曲的方法。在一个实施方式中，基于强化玻璃的制品包括第一表面，与第一表面相对的第二表面，以及第一表面与第二表面之间的边缘。边缘相对于平面是不对称的，所述
