Improved electro-optic devices are provided which may be in the configuration of variable transmittance windows, variable transmittance eyeglasses, variable transmittance light filters and displays and other devices wherein the transmittance of light therethrough automatically varies as a function of light impinging thereon. The electro-optic devices include a self-erasing electro-optic medium, and the transmittance of light through such medium varies as a function of electrical signals applied thereto through the agency of at least one photovoltaic cell, enclosed within the electro-optic device, and obviating the necessity of providing external drive voltage or external bleeder resistors or external wiring. In addition, a method and apparatus are provided for making such electro-optic devices.

A multilayer laminate and, more particularly a variable transmission window, which comprises: a) a thermochromic layer b) a photochromic layer wherein the thermochromic layer exhibits a net increase in its ability to absorb UV, visible, and/or near infrared light energy as the temperature of the system increases and a net decrease in its ability to absorb UV, visible and/or near infrared light energy as the temperature of the system decreases within the active range of the thermochromic layer.

Single-compartment, self-erasing, solution-phase electrochromic devices, solutions of electrochromic compounds for use as media of variable transmittance in such devices, and electrochromic compounds for such solutions are provided. The devices of the invention are surprisingly stable to cycling between light and dark states, have continuously variable transmittance to light as a function of electrical potential applied across the solution in a device, and have transmittance that can be varied over more than a factor of 10, from clear to dark or from dark to clear, in several seconds. Thus, the devices are especially suitable as variable transmittance components of variable transmission light filters, including windows, and variable reflectance mirrors, including anti-glare rearview mirrors in automobiles. Also provided are improved variable reflectance mirrors, wherein transmittance of reflected light is varied by thermochromic, photochromic or electro-optic means and wherein the reduction in transmittance which is required to eliminate perceptible reflection of an object to the eyes of an observer is reduced by disposing the plane of the highly reflective surface of the mirror at an angle with respect to the plane of the surface through which light from the object enters the mirror.

The present invention provides improved electrochromic layers, which comprise polymeric matrices with electrochromic solutions interspersed therein. Varying an electrical potential difference across a layer of the invention results in reversible variation in the transmittance of light across the layer because of electrochemical processes in the electrochromic solution of the layer. The invention further provides electrochromic devices, in which the electrochromic layers of the invention provide reversibly variable transmittance to light, and various apparatus in which the devices of the invention provide light-filtering or light-color modulation. Such apparatus include windows, including those for use inside and on the outside walls of buildings and in sunroofs for automobiles, and variable reflectance mirrors, especially rearview mirrors for automobiles.
摘要:
An electrochromic variable reflectance mirror for a vehicle includes a reflector/electrode on the third surface of the mirror. This reflector/electrode forms an integral electrode in contact with the electrochromic media, and may be a single layer of a highly reflective material or may comprise a series of coatings. When a series of coatings is used for the reflector/electrode, there should be a base coating which bonds to the glass surface and resists any adverse interaction, e.g., corrosive action, with the constituents comprising the electrochromic media, an optional intermediate layer (or layers) which bonds well to the base coating and resists any adverse interaction with the electrochromic media, and at least one highly reflective layer which directly contacts the electrochromic media and which is chosen primarily for its high reflectance, stable behavior as an electrode, resistance to adverse interaction with the materials of the electrochromic media, resistance to atmospheric corrosion, resistance to electrical contact corrosion, the ability to adhere to the base or intermediate layer(s) (if present) and to the epoxy seal, and ease of cleaning. If a base layer is deposited it preferably covers the entire third surface; however, when this is done the highly reflective layer may optionally only coat the central portion of the third surface and not the perimeter edge portion. The third surface reflector/electrode provides of improved electrical interconnection techniques used to impart a voltage drive potential to a transparent conductor on the mirror's second surface.
