Anti-dazzle glass, preparation method thereof, display screen and electronic equipment

The invention discloses anti-dazzle glass and a preparation method thereof, a display screen and electronic equipment. The preparation method comprises the following steps: providing smooth glass; the smooth glass surface is etched, a concave-convex structure is obtained, the depth of a concave part of the concave-convex structure ranges from 0.1 micrometer to 2 micrometers, and the span of the concave part ranges from 5 micrometers to 50 micrometers; the concave-convex structure is subjected to first laser annealing, the surface of the concave-convex structure is subjected to first recrystallization, first crystal particles protruding out of the surface of the concave-convex structure are generated on the surface of the concave-convex structure, the diameter of each first crystal particle is 0.5-2 microns, and the diameter of each first crystal particle is 1/8-1/12 of the span of the corresponding recess; the anti-dazzle glass is obtained. The first crystal particles are grown on the surface of the first-sta
