Abstract

A workpiece comprises a substrate. A texture layer is provided on the surface of one side of the substrate, and comprises a plurality of first-level regions; each first-level region comprises a plurality of structural units; the plurality of structural units comprise at least a first structural unit and a second structural unit connected to each other; the first structural unit and the second structural unit each internally comprise a plurality of sequentially arranged first texture stripes and a plurality of sequentially arranged second texture stripes; two ends of at least some first texture stripes both fall on the contour of the first structural unit; two ends of at least some second texture stripes both fall on the contour of the second structural unit; and the ends of the at least some first texture stripes are in contact with the ends of the at least some second texture stripes.

Dependent claims

A workpiece, comprising a substrate, a texture layer being provided on one side surface of the substrate, the texture layer comprising:

a plurality of first-level regions, the plurality of first-level regions presenting a light and shade change and each of the first-level regions comprising a plurality of structural units,
the plurality of structural units at least comprising a first structural unit and a second structural unit connected to the first structural unit,
the first structural unit comprising a plurality of sequentially arranged first texture stripes, two ends of at least some of the plurality of first texture stripes both falling on a contour of the first structural unit,
the second structural unit comprising a plurality of sequentially arranged second texture stripes, and two ends of at least some of the plurality of second texture stripes both falling on a contour of the second structural unit;
end portions of the at least some first texture stripes being in contact with end portions of the at least some second texture stripes;
and each texture stripe contained in each of the structural units being independently a protruding structure.
