Coating for Head-Up Display

A method of making a coated article, the method comprising:

• providing a first substrate having a No. 1 surface and a No. 2 surface opposite the No. 1 surface;
• applying a functional coating over at least a portion of the No. 2 surface, wherein applying the functional coating comprises:
• forming a first dielectric layer over at least a portion of the No. 2 surface, wherein forming the first dielectric layer comprises:
• forming a first film comprising tin oxide over at least a portion of the No. 2 surface, and
• forming a second film over at least a portion of the first film,
• wherein the first dielectric layer comprises a total thickness in a range of from 299 Å to 447 Å;
• forming a first metallic layer over at least a portion of the first dielectric layer, wherein the first metallic layer comprises a thickness in a range of from 125 Å to 162 Å;
• forming a second dielectric layer over at least a portion of the first metallic layer, wherein the second dielectric layer comprises a total thickness in a range of from 835 Å to 1052 Å;
• forming a second metallic layer over at least a portion of the second dielectric layer, wherein the second metallic layer comprises a thickness in a range of from 70 Å to 95 Å;
• and
• forming a third dielectric layer over at least a portion of the second metallic layer, wherein the third dielectric layer comprises a total thickness in a range of from 315 Å to 410 Å;
• wherein the functional coating is configured to reflect at least 10.0% of p-polarized radiation that contacts the functional coating at an incident angle of 60° relative to normal of the coated article, wherein the functional coating reflects the p-polarized radiation at a reflected angle ranging from 40° to 70° relative to normal of the coated article.

A vehicle head-up display system comprising:

• a radiation source;
• and
• a windshield comprising:
• a first substrate having a No. 1 surface and a No. 2 surface opposite the No. 1 surface;
• a second substrate having a No. 3 surface and a No. 4 surface opposite the No. 3 surface;
• an interlayer positioned between the No. 2 surface and the No. 3 surface;
• and
• a functional coating positioned on the No. 3 surface, the functional coating comprising:
• a first dielectric layer over at least a portion of the No. 3 surface, wherein the first dielectric layer comprises a first film comprising tin oxide over at least a portion of the No. 3 surface and a second film over at least a portion of the first film, and wherein the first dielectric layer comprises a total thickness in a range of from 299 Å to 447 Å;
• a first metallic layer over at least a portion of the first dielectric layer, wherein the first metallic layer comprises a thickness in a range of from 125 Å to 162 Å;
• a second dielectric layer over at least a portion of the metallic layer, wherein the second dielectric layer comprises a total thickness in a range of from 835 Å to 1052 Å;
• a second metallic layer over at least a portion of the second dielectric layer, wherein the second metallic layer comprises a thickness in a range of from 70 Å to 95 Å;
• and
• a third dielectric layer over at least a portion of the second metallic layer, wherein the third dielectric layer comprises a total thickness in a range of from 315 Å to 410 Å;
• wherein the radiation source is configured to emit radiation comprising p-polarized radiation at an incident angle of 60° relative to normal of the windshield;
• and
• wherein the functional coating is configured to reflect at least 10.0% of the p-polarized radiation at a reflected angle ranging from 40° to 70° relative to normal of the windshield.
