17. An electrochromic rearview mirror for a motor vehicle comprising;
-
(a) a first substantially transparent front substrate having a first and a second surface and coated with a substantially transparent conductive electrode coating on its second surface;
(b) a rear substrate having a third and a fourth surface, said rear substrate positioned in spaced-apart relationship with said front substrate and with the third surface of said rear substrate opposing the second surface of said front substrate;
(c) a partially transmitting/substantially reflecting mirror reflector disposed on the third surface of said rear substrate;
(d) a seal positioned toward a peripheral edge of each of said substrate of (a) and said substrate of (b) and forming a cavity therebetween;
(e) an electrochromic medium disposed in said cavity and contacting said substantially transparent conductive electrode coating of said front substrate and said partially transmitting/substantially reflecting mirror reflector disposed on the third surface of said rear substrate;
(f) said mirror reflector comprising at least one metal layer, said mirror reflector reflecting at least about 55% of visible light incident thereon;
(g) a display device disposed behind said fourth surface of said rear substrate such that light emitted by said display device passes through said rear substrate, through said partially transmitting/substantially reflecting mirror reflector, through said substantially transparent conductive electrode coating and through said front substrate when said display device is electrically powered; and
(h) said rear substrate with said partially transmitting/substantially reflecting mirror reflector disposed on the third surface thereof having a visible light transmission in the range from about 1% transmission to about 30% transmission. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)

59. An electrochromic rearview mirror for a motor vehicle comprising;
-
(a) a first substantially transparent front substrate having a first and a second surface and coated with a substantially transparent conductive electrode coating on its second surface;
(b) a rear substrate having a third and a fourth surface, said rear substrate positioned in spaced-apart relationship with said front substrate and with the third surface of said rear substrate opposing the second surface of said front substrate;
(c) a partially transmitting/substantially reflecting mirror reflector disposed on the third surface of said rear substrate;
(d) a seal positioned toward a peripheral edge of each of said substrate of (a) and said substrate of (b) and forming a cavity therebetween;
(e) an electrochromic medium disposed in said cavity and contacting said substantially transparent conductive electrode coating of said front substrate and said partially transmitting/substantially reflecting mirror reflector disposed on the third surface of said rear substrate;
(f) said mirror reflector comprising at least one metal layer, said mirror reflector reflecting at least about 55% of visible light incident thereon;
(g) a display device disposed behind said fourth surface of said rear substrate such that light emitted by said display device passes through said rear substrate, through said partially transmitting/substantially reflecting mirror reflector, through said substantially transparent conductive electrode coating and through said front substrate when said display device is electrically powered; and
(h) said rear substrate with said partially transmitting/substantially reflecting mirror reflector disposed on the third surface thereof having a visible light transmission in the range from about 1% transmission to about 30% transmission. (i) wherein light absorbing means that substantially absorb visible light are disposed substantially across said fourth surface of said rear substrate except generally at where said display device is disposed. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112)
