Abstract

The present invention relates to a process for gratings able to resist dizziness, enhance color displayed, eliminate static electricity and block radiation. Steps included are: making a substrate with an enhanced glass or optical plastic glass or optical plastics; coating the surface of the substrate with dizziness-resistant films composed of evenly distributed nano-particles, wherein the inner layer is made of Cu particles or Al particles and the outer layer is made of Cr particles; forming a static-electricity-resistant layer on the grating'"'"'s surface so as to form an optical diffraction grating able to resist dizziness, enhance color displayed, eliminate static electricity and block radiation.

Claims

1. A process for creating a coated substrate for resisting dizziness, enhancing color, eliminating static electricity and blocking radiation, which comprises the steps of:

a) supplying a substrate composed of a material selected from a group consisting of enhanced glass, optical plastic glass and optical plastic;

b) plating said substrate with dizziness-resistant films composed of evenly distributed nano-particles, having an inner layer composed of Cu or Al particles and an outer layer consisting of Cr particles; and

c) forming a static-electricity-resistant layer on the dizziness-resistant films.

2. The process according to claim 1, wherein said dizziness-resistant films of the plating step b) are formed by immersing said substrate in an electroplate trough and plating for 5-20 minutes to form several films each with a thickness between 0.1 mm-0.3 mm.

3. The process according to claim 1, wherein said static-electricity-resistant layer of the forming step c) is a conductive metal net composed of conductive nano-fibers embedded in a base made from one of PET and PC, so as to eliminate static electricity caused by monitors.
