Abstract

The present disclosure generally relates to a vehicle glazing (e.g., vehicle windshield) having an opaque enamel printed opening for an information acquisition system and a darkening source within the opaque enamel printed opening to reduce optical transmittance distortion and improve performance of information acquisition systems (e.g., an imaging system, electric sensor(s), video camera(s), distance sensor(s)) associated with a vehicle. The darkening source, which may not undergo extreme heat treatment above 500 deg. C., provides a darkening source open area within the opaque enamel print open area, wherein the darkening source open area provides an opening through which the information acquisition system may receive information from outside a vehicle.

First claim

1 . An automotive glazing, comprising:
at least one glass substrate; an opaque print on the at least one glass substrate, wherein the opaque print provides a first open area for an information acquisition system, wherein the first open area is larger than a required opening for the information acquisition system, and wherein the automotive glazing comprises a first distortion within the first open area; and a second open area within the first open area, wherein the second open area is at least as large as the required opening for the information acquisition system, and wherein the automotive glazing comprises a second distortion within the second open area, such that the second distortion is less than the first distortion.

2 . An automotive laminated glazing, comprising:
a first glass substrate having at least surfaces S 1 and S 2 , wherein S 1 faces a vehicle exterior; a second glass substrate having at least surfaces S 3 and S 4 , wherein S 4 faces a vehicle interior; a first interlayer between the first and second glass substrates; an opaque print providing a first open area for a first information acquisition system, wherein the first open area is larger than a first required opening for the first information acquisition system; and a first darkening source at least partially within the first open area, wherein the first darkening source provides a second open area within the first open area, wherein the first required opening fits within the second open area, wherein the first darkening source does not undergo heat treatment greater than 500 deg. C., and wherein the first open area is larger than the second open area in square mm.

3 . The automotive laminated glazing according to claim 2 , wherein the average visible light transmittance across the entire first open area is less than 70% and the average visible light transmittance across the entire second open area is at least 70%.

4 - 5 . (canceled)

6 . The automotive laminated glazing according to claim 2 , wherein the first darkening source has a visible light transmittance of less than or equal to 3%.

7 . The automotive laminated glazing according to claim 2 , wherein the first darkening source is at least one selected from the group consisting of a print, a substrate, a coating, a colored interlayer and an obscuration adjacent to S 4 .

8 - 9 . (canceled)

10 . The automotive laminated glazing according to claim 7 , wherein the print is on at least one selected from the surfaces S 2 , S 3 and S 4 and the first interlayer.

11 . (canceled)

12 . The automotive laminated glazing according to claim 7 , wherein the substrate comprises at least one printed surface.

13 . The automotive laminated glazing according to claim 7 , wherein the substrate is a polymer film.

14 - 17 . (canceled)

18 . The automotive laminated glazing according to claim 13 , wherein the polymer film is adjacent to at least one surface selected from S 2 , S 3 , and S 4 .

19 . The automotive laminated glazing according to claim 13 , wherein the polymer film includes an electrical component.

20 - 23 . (canceled)

24 . The automotive laminated glazing according to claim 7 , wherein a portion of the first interlayer is removed and replaced with the colored interlayer.

25 . (canceled)

26 . The automotive laminated glazing according to claim 7 , wherein the obscuration is a mounting device for attaching an object to the automotive laminated glazing or a mating device located between the automotive laminated glazing and another object.

27 - 28 . (canceled)

29 . The automotive laminated glazing according to claim 2 , wherein the first darkening source completely surrounds the second open area.

30 . The automotive laminated glazing according to claim 2 , wherein the first darkening source does not surround the entire second open area.

31 . (canceled)

32 . The automotive laminated glazing according to claim 2 , further comprising
a second information acquisition system, wherein the second information acquisition system has a second required opening, wherein the opaque print further comprises a third open area, separate from the first open area, such that the third open area is larger than the second required opening of the second information acquisition system; and a second darkening source, wherein the second darkening source is located at least partially within the third open area, wherein the second darkening source provides a fourth open area within the third open area, wherein the second required opening fits within the fourth open area.

33 - 34 . (canceled)

35 . The automotive laminated glazing according to claim 2 , further comprising a second information acquisition system having a second required opening,
wherein the first darkening source further provides a third open area within the first open area, wherein the second required opening fits within the third open area.

36 - 44 . (canceled)

45 . The automotive laminated glazing according to claim 2 , wherein an edge of the first open area is from 2 mm to 6 mm from an edge of the second open area.

46 - 47 . (canceled)

48 . An automotive glazing, comprising:
a glass substrate having surfaces S 1 and S 2 , wherein S 1 faces a vehicle exterior; an opaque print providing a first open area for an information acquisition system, wherein the first open area is larger than a required opening for the information acquisition system; and a darkening source at least partially within the first open area, wherein the darkening source provides a second open area within the first open area, wherein the required opening for the information acquisition system fits within the second open area.

49 . The automotive glazing according to claim 48 , wherein the average visible light transmittance across the entire first open area is less than 70% and the average visible light transmittance across the entire second open area is at least 70%.

50 - 55 . (canceled)

56 . The automotive glazing according to claim 48 , wherein the second open area is closer to the information acquisition system than the first open area, and wherein the first open area is larger than the second open area in square mm.
