Abstract
A low-gloss metal plate includes a metal body and a plurality of metal pattern units. The metal body has a first surface and a second surface opposite to each other. The plurality of metal pattern units protrude from the first surface and are arranged to form a regular pattern. One of the plurality of metal pattern units has a top, a base and a sidewall. The base at least partially overlaps with the first surface. The sidewall connects the top with the base and forms an angle less than 60° with the base.

A low-gloss metal plate serving as a metal part of a display housing, comprising:
- a metal body, having a first surface and a second surface opposite to each other;
- and
- a plurality of metal pattern units, protruding from the first surface and arranged to form a regular pattern;
- wherein one of the plurality of metal pattern units has a top, a base and a sidewall;
- the base at least partially overlaps with the first surface;
- the sidewall connects the top with the base and forms an angle less than 60° with the base;
- wherein the low-gloss metal plate has a gloss substantially less than 20 GU.
A method for fabricating a low-gloss metal plate serving as a metal part of a display housing, comprising:
- providing a metal body having a first surface and a second surface opposite to each other;
- and
- performing a physical processing step on the first surface to form a plurality of metal pattern units protruding from the first surface and arranged to form a regular pattern;
- wherein one of the plurality of metal pattern units has a top, a base and a sidewall;
- the base at least partially overlaps with the first surface;
- the sidewall connects the top with the base and forms an angle less than 60° with the base;
- wherein the low-gloss metal plate has a gloss substantially less than 20 GU.
