Embodiment 1

[0040] Example 1: Laminated switchable panoramic sunroof ( image 3 ) consists of two layers of 2.4mm solar green soda lime glass2. Two gray bonding interlayers 4 are used to bond a single switchable film (SPD film) 28 to the glass layer 2 . The total visible light transmission of the laminate in the on state was 5%, and the total visible light transmission of the laminate in the off state was 27%. Along each long edge, one edge of each TCO-coated layer 10 was cut off 12 mm along the entire length. Cuts are formed on opposing surfaces and sides of the TCO coating. The cutout exposes the active material layer. Active material was scraped off with a plastic spatula. The surface is then cleaned with a solvent such as alcohol, hexane, heptane, etc. Such as Figure 4 A continuous 3 mm wide line was then printed directly onto the TCO surface 10 using a flexible conductive material (silver via paste) 12, 6 mm inward from the edge, as shown. The flexible conductive material (si...

Embodiment 2

[0041] Embodiment 2: This embodiment is the same as Embodiment 1 except that the silver vias are printed. Print 3mm diameter circles every 25mm along the edge (eg Figure 5 those circles shown in ).

Embodiment 3

[0042] Embodiment 3: This embodiment is the same as Embodiment 1 except that silver vias are printed. A 1.5 mm continuous line of silver via paste 12 is printed along the length of and centered on the cutout.

Abstract

A switchable laminated glazing with improved bus bar that solves the problem of inhomogeneities and reduce the cost of its fabrication by providing a laminated glazing that comprise a switchable layer (14) that has an active material sandwiched between two conductive coated plastic layers (8), at least two bus bars (20) in electrical contact with the respective conductive coated plastic layer (8), and at least two pliable conductive media (12), each of them between the respective coated plastic layer (8) and bus bar (20). The area covered by pliable conductive medias (12) is substantially less than the area covered by bus bars (20). The invention provides an improved lower cost bus bar by sparing use of a pliable conductive media and by using a pliable conductive media in different kind of configurations.

Description

technical field [0001] This application relates to the field of switchable automotive laminated glazing. Background technique [0002] Reducing vehicle weight has become a key strategy as automakers strive to meet government regulations on fuel efficiency and emissions, and to deliver the environmentally friendly vehicles that the public increasingly demands. While lightweight material substitution has been a big part of this trend, we are also seeing a reduction in the average size of most vehicles. As cabin space shrinks, it can lead to an unpleasant claustrophobic response. To solve this problem, manufacturers have been increasing the glass area of ​​vehicles for several years. Increased natural light and views help give the cabin a more open and airy feel. [0003] However, especially on vehicles equipped with panoramic windshields and sunroofs, sun control and maintaining a comfortable lighting level can be difficult with the increased glass area. [0004] A panoram...
