Electrochromic element and electrochromic device including electrochromic element

Abstract

In the electrochromic device according to the embodiment of the present application, when the first voltage is applied to the electrochromic device in a state where the electrochromic element has the first state, the electrochromic device changes to the second state, and When the first voltage is applied in a state where the electrochromic element has the fourth state, the electrochromic element becomes the third state.

Description

technical field [0001] The present application relates to electrochromic elements and electrochromic devices including electrochromic elements, and more particularly, to electrochromic elements whose optical states change and electrochromic devices for changing the optical states of electrochromic elements . Background technique [0002] Electrochromism is a phenomenon that changes color based on oxidation-reduction (redox) action caused by applied electric power. Materials that can be electrochromic can be defined as electrochromic materials. An electrochromic material has the 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 to it, or conversely, displaying a color when no power is applied to it from the outside and then when power is applied to it Color properties are not displayed. [0003] Electrochromic devices containing electrochromic materials have been used for various purposes. ...

AI Technical Summary

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
