  • Publication number: 20230116462
    Abstract: An electrochromic device composed of a pattern forming layer, an optical coating layer, an electrochromic component, and an opaque white layer arranged is revealed. The pattern forming layer has at least one pattern-shaded hollow hole for exposure of the optical coating layer. The optical coating layer which includes at least two layers of high and low refractive index material stacked alternately is the main layer to render colors. When transmittance of the electrochromic component which generates color changes is lower than 50%, a difference in the transmittance at 500 nm, 600 nm, and 700 nm is no more than 10%. Under such colored state, the color of light reflected by the optical coating layer is enhanced. The opaque white layer is for a sharper color contrast of the reflected light. Thereby light reflected by the optical coating layer show colors different from those of the electrochromic component in bleached and colored states.
