Electro-optic system configured to reduce a perceived color change |
摘要 |
An electro-optic system is provided that includes a front element having first and second surfaces, a rear element including third and fourth surfaces, wherein the front and rear elements are sealably bonded together in a spaced-apart relationship to define a chamber, and an electro-optic medium contained in the chamber, and the electro-optic medium is adapted to be in at least a high transmittance state and a low transmittance state. The electro-optic system further includes a display device in optical communication with the electro-optic element, the display device including at least one light source and is configured to emit at least a first primary and a second primary, the first and second primaries each having a first hue (hab) when viewed through the electro-optic element in approximately the high transmittance state and a second hue (hab′) when viewed through the electro-optic element in approximately the low transmittance state, wherein a change in the first and second hues (Δhab) for both first and second primaries is less than approximately 31 degrees. |

1. An electrochromic system comprising:
an electrochromic element comprising:
a front element comprising first and second surfaces;a transparent electrode on said second surface;a rear element comprising third and fourth surfaces, wherein said front and rear elements are sealably bonded together in a spaced-apart relationship to define a chamber, such that said second surface and said third surface face one another; andan electrochromic medium contained in said chamber, wherein said electrochromic medium is adapted to be in at least a high transmittance state and a low transmittance state, wherein light passing through said electrochromic element has at least a first primary and a second primary, and said first and said second primaries each have a first hue (hab) when passing through said electrochromic medium in said high transmittance state and a second hue (hab′) when passing through said electrochromic element in approximately said low transmittance state, wherein a change in said first and second hues (Δhab) for both said first and second primaries is less than approximately 31 degrees, wherein a ratio of intensities of said first and second primaries remains approximately constant. |
