摘要:
A system and method for color correction in an electrochromic device includes applying a stepped voltage profile to the electrochromic device in a high-transmission state to achieve a desired low-transmission state. Each step of the stepped voltage profile is at a step difference of about 0.01 volts to about 0.5 volts from an adjacent step with each successive step being at a varying voltage level and each of the steps is held for a time period from about 0.1 seconds to about 10 seconds. At the desired low-transmission state, the system and method include applying a reverse bias voltage from about 0.01 volts to about 0.5 volts for about 0.01 seconds to about 10 seconds to color correct the low-transmission state.
