Abstract
An electrically heatable panel may include a conductive coating patterned to have a conductive profile with a narrow region whereby current density is greater in the narrow region thus providing increased heat dissipation in the narrow region.
Claims20
An electrically heatable panel, comprising:
- a first glass sheet;
- first and second spaced apart bus bars;
- and
- an electrically conductive coating adjacent the first glass sheet disposed between the first and second spaced apart bus bars, the electrically conductive coating having a conductive profile with at least one locally narrow region.
1 more element
An electrically heatable windshield for a vehicle, comprising:
- a conductive coating substantially completely covering the windshield;
- the conductive coating having an effective conduction region and at least one current isolated region;
- and,
- a first bus bar and a second bus bar ohmically coupled to the effective conduction region.
1 more element
A method for manufacturing a heated windshield, comprising:
- coating a windshield sheet substrate with a conductive coating to substantially completely cover the windshield;
- ohmically coupling the conductive coating between a first bus bar and a second bus bar;
- and
- selectively removing the conductive coating along isolation paths to pattern an effective conduction region and current isolated regions, wherein the effective conduction region comprises a conductive profile with at least one locally narrow region between the first bus bar and the second bus bar.
