example 1

[0038] The structure of the electrochromic rearview mirror is as follows: figure 1 As shown, the thicknesses of the substrates 11 and 12 are 2.0 mm, respectively. The ITO electrode layers 13 and 14 have a thickness of 1500 Å and a resistance value of 6Ω. The sealing layer 16 has a thickness of 100 μm. In the reflective layer 17, aluminum accounts for 70%, titanium accounts for 30%, and the thickness of the metal is about 150nm. In this example, a protective layer is provided behind the reflective layer, and the material is silicon, titanium or indium oxide, and the thickness is about 200 Å. When no voltage is applied, the surface reflectance of the electrochromic rearview mirror device is about 70%. When a working voltage of 1.5v is applied, the color change is completed within 1 second, and the mirror surface appears dark blue. At this time, the reflectance is about 9%, which can moderately prevent glare. The lens group can repeat color change more than 200,000 times.

[0047] The structure of the electrochromic rearview mirror is as follows: image 3 As shown, the thicknesses of the substrates 31 and 32 are 1.3 mm, respectively. The thickness of the ITO electrode layer 33 is about 1500 Å, and the resistance value is 6Ω. The composite electrode ITO layer 34 has a thickness of about 1500 Å, a resistance value of 6Ω, aluminum in the metal layer 37 accounts for 70%, titanium accounts for 30%, and the metal thickness is about 150nm. The sealing layer 36 has a thickness of 150 μm. When no voltage is applied, the surface reflectance of the electrochromic rearview mirror device is about 79%, and the mirror surface is slightly golden yellow. When a 1.5v working voltage is applied, the color change is completed within 1 second, and the mirror surface appears dark blue. At this time, the reflectivity is about 12% for moderate protection against glare. This lens group can repeat color change more than 2,000 times.

[0049] The structure of the electrochromic rearview mirror is as follows: image 3 As shown, the thicknesses of the substrates 31 and 32 are 1.3 mm, respectively. The thickness of the ITO electrode layer 33 is about 1500 Å, and the resistance value is 6Ω. The composite electrode ITO layer 34 has a thickness of about 1500 Å and a resistance value of 6Ω. The metal layer 37 is silver metal with a thickness of about 150 nm. The sealing layer 36 has a thickness of 150 μm. When no voltage is applied, the surface reflectance of the electrochromic rearview mirror device is about 82%, and the mirror surface is bright silver. When a 1.5v working voltage is applied, the color change is completed within 1 second, and the mirror surface appears dark blue. At this time, the reflectivity is about 12% for moderate protection against glare. This lens group can repeat color change more than 2,000 times.

Abstract

This invention discloses an electric metachromatic mirror set and its reflecting layer material including a first and second parallel (light transmission) baseplates with a space in between; first and second electrodes set on the two baseplates separately facing the opposite side of the side space for providing a voltage and the first electrode allow light to transmit; an electric metachromatic solution placed in the space between the two suits the voltage to change color; a seal material between the two seals the said solution in it and a reflecting layer on the second plate reflects light entering the electric metachromatic mirror set transmitting the first plate back to the said first baseplate, the reflecting layer is a compound layer of ALTi alloy or In Sn oxide / high reflecting metal (Cr, AlTi alloy or Ag).

Description

technical field [0001] The invention relates to an electrochromic (electrochromic) mirror group, and a reflective layer material used in the electrochromic mirror group, so that the reflective layer material can make the electrochromic mirror group produce required color changes and good electrochromic Discoloration properties. Background technique [0002] Glare is one of the annoying factors when driving. There have been many efforts in the past to try to solve the glare problem. One of the most effective methods so far is to install an electrochromic component in the vehicle's rearview mirror. The electrochromic component darkens the rear view mirror, thereby reducing the reflectivity of the mirror to minimize the glare effect. figure 1 Shown is a schematic diagram of an existing electrochromic unit used in a rearview mirror assembly of a vehicle to achieve color change. [0003] An electrochromic unit generally includes two glass substrates 11 and 12 placed in parall...
