1. A micro-lens structure, comprising: micro-lens units distributed in an array, wherein each said micro-lens unit comprises at least two micro-lenses made of a photoresist; and
the at least two micro-lenses have different arch heights;
wherein the micro-lens units are distributed in an array in a first direction; and the at least two micro-lenses in each said micro-lens unit are alternately arranged in the first direction;
wherein the micro-lenses comprise at least one of a cylindrical micro-lens and a spherical micro-lens, and the micro-lens unit comprises at least one said cylindrical micro-lens and multiple said spherical micro-lenses;
a lengthwise direction of the cylindrical micro-lens is a second direction that is perpendicular to the first direction; and
in the second direction, the multiple spherical micro-lenses are sequentially arranged in a spaced manner.
