Claims31
A variable reflectance mirror for a motor vehicle comprising as the variable transmittance component a single-compartment, self-erasing, solution-phase electrochromic device wherein the sheet resistance of a transparent electrode layer of the electrochromic device is 1-40 ohms per square.
A variable reflectance mirror for a motor vehicle which comprises as the variable transmittance component a single-compartment, self-erasing, solution-phase electrochromic device and which has a range of reflectance from greater than 70% to less than 10%.
A variable reflectance mirror for a motor vehicle comprising a single-compartment, self-erasing, solution-phase electrochromic device which is gray-scale controllable over a range of reflectance by applying potential differences between the electrode layers of the device of 0.2 volts to 1.5 volts.
A variable reflectance mirror for a motor vehicle which comprises as the variable transmittance component a single-compartment, self-erasing, solution-phase electrochromic device which comprises two planar, parallel, spaced-apart electrode layers, to which DC current is provided through leads connected to a DC power source, said device oriented so that the lead connected the electrode layer which is the anode, to the power source is higher in elevation than the lead connecting the electrode, which is the cathode, to the power source.
