AI Technical Summary
Technical Problem
Existing high-thermal-performance windows reflect the sky and landscape, causing birds to misjudge their flight paths, increasing the risk of collisions, and there is a lack of cost-effective technologies to reduce bird collisions.
Method used
A coating with a predetermined pattern is applied to the window surface, a contrasting surface is formed using nanoparticle materials, and a first coating and a functional layer are applied using a magnetron sputtering vapor deposition process to reduce bird collisions.
Benefits of technology
By creating contrasting patterns visible to birds on the window surface, the risk of birds colliding with the window is reduced, while maintaining high thermal performance and cost-effectiveness.

Abstract
A coated substrate for reducing bird collisions, such as in architectural windows, is disclosed. The coated substrate includes a first substrate having a first surface and a second surface disposed opposite to the first surface; wherein the second surface includes at least one functional layer thereon; and wherein the first surface includes a first coating having a predetermined pattern that contrasts in the UV and / or bird-visible range when compared to an uncoated portion of the first surface of the substrate, or when compared to other coated portions of the first surface. The coated substrate can be used as a single substrate in an architectural window or as a substrate in an insulating glass unit. A method for forming an architectural window to reduce bird collisions using upward sputtering and downward sputtering processes is also provided.
