Disclosed are a micro-lens structure, a displaying device, and a machining method of the micro-lens structure. The micro-lens structure specifically comprises: micro-lens units distributed in an array, wherein each micro-lens unit comprises at least two micro-lenses made of a photoresist, and the at least two micro-lenses have different arch heights.

An optical lens with laser induced periodic surface structure has an optical lens made in one-piece with a surface and a convex surface. The convex surface has a microstructure of periodic surface induced and formed by laser. The periodic surface structure has a plurality of linear structures periodically arranged with an interval of 50 nm-1000 nm between each other and a height of 50 nm-500 nm.

A method for forming optical elements at a surface of an ophthalmic lens including a lens material includes providing a laser interaction layer at a surface of the ophthalmic lens, the laser interaction layer including a first material having a first absorption of radiation at a first wavelength, ?.sub.1, the lens material having a second absorption of radiation at ?.sub.1, the second absorption being lower than the first absorption, exposing discrete areas of the laser interaction layer to laser radiation at ?.sub.1 sufficient to form an optical element at each discrete area in the lens material.

The present disclosure relates to the field of display technology, and provides a polarizer, a display panel, and a manufacturing method for the two. The method for manufacturing a polarizer comprises: providing a flat, semi-finished polarizing product comprising a linear polarizing sheet and a phase difference layer stacked over each other; providing an abutment comprising a supporting plane, wherein at least a portion of an edge of the supporting plane is provided with an accurate chamfer forming a supporting curved surface; fitting the semi-finished polarizing product onto a side of the supporting plane, wherein at least a portion of the supporting curved surface has an orthographic projection, positioned at an edge of the semi-finished polarizing product, in a plane where the semi-finished polarizing product is located; and applying a moist and heated gas to the edge of the semi-finished polarizing product to fit it onto a side of the supporting curved surface.
