Abstract
A coated glazing useful for vehicles includes a first glass substrate, and a heatable coating formed on the first glass substrate, the heatable coating including at least one heatable layer, at least one dielectric layer, and at least one integrated portion of a heatable layer and a dielectric layer, wherein the integrated portion is formed in a differential heating area of the heatable coating, for variably heating the first glass substrate for deicing wiper park areas or any other heating desirable areas.
Claims20
A glazing comprising:
- a first glass substrate;
- a heatable coating formed on the first glass substrate, the heatable coating including at least one heatable layer, at least one dielectric layer, and at least one integrated portion of at least one of the at least one heatable layer and at least one of the at least one dielectric layer;
- and
- at least one busbar formed on the heatable coating and located separate from the at least one integrated portion,
- wherein the integrated portion is formed in a differential heating area of the heatable coating.
A method of providing a glazing with a heatable coating, comprising the steps of:
- providing a first glass substrate formed with a heatable coating including at least one heatable layer and at least one dielectric layer;
- forming an integrated portion of at least one of the at least one heatable layer and at least one of the at least one dielectric layer in a differential heating area;
- and
- providing a busbar formed on the heatable coating and located separate from the integrated portion.
A laminated glazing comprising:
- a first glass sheet having surfaces S1 and S2, wherein S1 faces an exterior when installed and a second glass sheet having surfaces S3 and S4, wherein S4 faces an interior when installed;
- an interlayer provided between the first and second glass sheets;
- a heatable coating formed on either of the first and second glass sheets, the heatable coating including a first heatable region and a second heatable region having a higher heating capability than that of the first heatable region, wherein the heatable coating includes at least one heatable layer, at least one dielectric layer and at least one integrated portion of at least one of the at least one heatable layer and at least one of the at least one dielectric layer, wherein the integrated portion is formed in the second heatable region;
- a busbar supplying power to the heatable coating, the busbar formed on the heatable coating and located separate from the at least one integrated portion;
- and
- an opaque print formed on at least one of the first and second glass sheets, the opaque print hiding the busbar and the second heatable region when viewed from an exterior side of the first glass sheet.
