1. An electrochromic window comprising:
a first substantially transparent substrate comprising a first electrochromic device disposed thereon; and
a second substantially transparent substrate comprising a second electrochromic device disposed thereon;
wherein the first and second substantially transparent substrates are registered, one in front of the other, and the electrochromic window is configured to transition the first electrochromic device and/or the second electrochromic device to provide up to four optical states for the electrochromic window;
wherein the electrochromic window comprises an insulated glass unit having an interior space between the first substantially transparent substrate and the second substantially transparent substrate, the interior space comprising a gas or a vacuum; and
wherein the electrochromic window is configured such that transitions in the first electrochromic device and/or the second electrochromic device are configured to complement each other and to reduce curtaining effect.
