    Abstract: Described herein is a polymorphic display, which is a unitary apparatus constructed such that a wide variety of electro-optic functions are enabled. The polymorphic display, even when having multiple pixels, enables sharing of selected structures among the pixels. In a multi-pixel construction, there is a set of pixels in the display that exhibit one set of operable properties, such as particular stability, sequencing, and switching properties, and another set of pixels that are different from the first set. That is, they have different stability, sequencing, or switching properties. In such a way, a highly flexible polymorphic display may be construed to satisfy a wide range of display needs.

  • Patent number: 11181798
    Abstract: 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.
