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.
