Micro-lens structure, displaying device, and machining method of micro-lens structure

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.
