Title:
ELECTROCHROMIC ELEMENT AND DISPLAY SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/039121
Kind Code:
A1
Abstract:
The present invention provides an electrochromic (EC) element that comprises a first electrode, an electrochromic layer located on the first electrode and made of an electrochromic material, an electrolyte layer located on the electrochromic layer, and a second electrode located on the electrolyte layer, and satisfies at least one of the following conditions (1) and (2): (1) the first electrode and/or the second electrode includes a plurality of regions each having a different resistance value from an external power source; (2) the electrolyte layer includes a plurality of regions each comprising a different electrolyte material. In the condition (1), each of the plurality of regions may be an electrode formed as a block shape and/or a linear shape. In the condition (1), the plurality of regions may be arrayed so that each resistance value in the plurality of regions increases sequentially from the region at one end toward the region at the other end.
