Abstract

A virtual image system for windshields that permits an image source to reflect off the windshield so that a virtual image, free of ghost image, is visible to the driver. Either a matte black material is applied to a windshield glass pane at any of the outer glass pane windshield surfaces 1 or 2 , or at the inner glass pane windshield surface 3 , or else a black glossy sheet is disposed at windshield surface 4 upon the windshield frit, whereby the virtual image is provided for any image source having real image rays incident at windshield surface 4.

Claims (59)

1 . A virtual image system, comprising:

a laminated windshield, comprising:

an outer glass pane having a windshield surface 1 and an opposite windshield surface 2 ;

an inner glass pane having a windshield surface 3 and an opposite windshield surface 4 ; and

a plastic layer disposed between said outer and inner glass panes, wherein windshield surfaces 2 and 3 abut said plastic layer;

a matte black material disposed on at least one of said windshield surfaces 1 , 2 and 3 ; and

an image source which provides real image rays which are incident at said windshield surface 4 ;

wherein the real image rays reflect at said windshield surface 4 and thereby provide virtual image rays, the virtual image rays providing a virtual image;

wherein refracted rays of the real image rays which transmit into the windshield strike the matte black material such as to prevent ghost image rays; and

wherein the virtual image is free from ghost image.

2 . The virtual image system of claim 1 , wherein said matte black material is disposed at said windshield surface 1 .

3 . The virtual image system of claim 2 , wherein said matte black material is a frit material.

4 . The virtual image system of claim 3 , wherein said matte black material is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

5 . The virtual image system of claim 1 , wherein said matte black material is disposed at said windshield surface 2 .

6 . The virtual image system of claim 5 , wherein said matte black material is a frit material.

7 . The virtual image system of claim 6 , wherein said matte black material is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

8 . The virtual image system of claim 1 , wherein said matte black material is disposed at said windshield surface 3 .

9 . The virtual image system of claim 8 , wherein said matte black material is a frit material.

10 . The virtual image system of claim 9 , wherein said matte black material is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

11 . A virtual image system, comprising:

a laminated windshield, comprising:

an outer glass pane having a windshield surface 1 and an opposite windshield surface 2 ;

an inner glass pane having a windshield surface 3 and an opposite windshield surface 4 ; and

a plastic layer disposed between said outer and inner glass panes, wherein windshield surfaces 2 and 3 abut said plastic layer;

a black glossy sheet disposed at said windshield surface 4 ; and

an image source which provides real image rays which are incident at said black glossy sheet;

wherein the real image rays reflect at said black glossy sheet and thereby provide virtual image rays, the virtual image rays providing a virtual image; and

wherein the virtual image is free from ghost image.

12 . The virtual image system of claim 11 , wherein:

said laminated windshield further comprises a peripheral frit located on said windshield surface 4 ; and wherein

said glossy black sheet is adhered to said frit, wherein said frit is at least co-extensive with said glossy black sheet.

13 . The virtual image system of claim 12 , wherein said black glossy sheet is a self-adhering mylar applique.

14 . The virtual image system of claim 13 , wherein said black glossy sheet is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

15 . A laminated windshield, comprising:

an outer glass pane having a windshield surface 1 and an opposite windshield surface 2 ;

an inner glass pane having a windshield surface 3 and an opposite windshield surface 4 ;

a plastic layer disposed between said outer and inner glass panes, wherein windshield surfaces 2 and 3 abut said plastic layer; and

a matte black material disposed on at least one of said windshield surfaces 1 , 2 and 3 .

16 . The laminated windshield of claim 15 , wherein:

said matte black material is disposed at said windshield surface 1 ;

said matte black material is a frit material; and

said matte black material is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

17 . The laminated windshield of claim 15 , wherein:

said matte black material is disposed at said windshield surface 2 ;

said matte black material is a frit material; and

said matte black material is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

18 . The laminated windshield of claim 15 , wherein:

said matte black material is disposed at said windshield surface 3 ;

said matte black material is a frit material; and

said matte black material is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.

19 . A laminated windshield, comprising:

an outer glass pane having a windshield surface 1 and an opposite windshield surface 2 ;

an inner glass pane having a windshield surface 3 and an opposite windshield surface 4 ;

a plastic layer disposed between said outer and inner glass panes, wherein windshield surfaces 2 and 3 abut said plastic layer;

a peripheral frit located on said windshield surface 4 ; and

a black glossy sheet disposed on the frit of said windshield surface 4 .

20 . The laminated windshield of claim 19 , wherein:

said black glossy sheet is a self-adhering mylar applique; and

said black glossy sheet is disposed substantially adjacent a base of the windshield, between a predetermined upper sightline and a predetermined lowest sightline.
