Problems solved by technology

[0004] In the case of electrochromic devices, since the discoloration occurs due to electrical power, there is the technical problem of having to properly control the applied voltage to achieve the desired degree of discoloration
[0005] Also, since electric power is required in the color changing process and maintenance process of the electrochromic device, there is a problem that power consumption increases as the area increases
[0006] Also, when the driving module for power supply is arranged in the electrochromic device, the driving module is not effectively arranged in the electrochromic device, and there is a problem that the inside of the electrochromic device becomes complicated
[0007] Also, since the electrochromic speed of the electrochromic element is slow and the uniformity of the electrochromic element is low, there is a problem that the performance of the application including the electrochromic element deteriorates

Abstract

An embodiment of the present application provides an electrochromic device comprising an electrochromic element, wherein the electrochromic element enters a second state when a first voltage is applied to the electrochromic element in a state where the electrochromic element has a first state, and the electrochromic element enters a third state when the first voltage is applied to the electrochromic element in a state where the electrochromic element has a fourth state.

Description

technical field [0001] The present application relates to an electrochromic element and an electrochromic device comprising the electrochromic element, and more particularly, to an electrochromic element whose optical state changes and an electrochromic device for changing the optical state of the electrochromic element . Background technique [0002] Electrochromism is a phenomenon in which color changes based on an oxidation-reduction (redox) action caused by applied electric power. Materials that can be electrochromic can be defined as electrochromic materials. An electrochromic material has a property of not displaying a color when no power is applied to it from the outside and then displaying a color when power is applied thereto, or conversely, displaying a color when no power is applied to it from the outside and then displaying a color when power is applied thereto does not display the properties of the color. [0003] Electrochromic devices comprising electrochro...
