Problems solved by technology

[0003] Generally speaking, providing a higher potential can relatively accelerate the coloring speed, but the instantaneous application of a high potential also accelerates the damage rate of the electrochromic element. Coloring can prolong the service life of the electrochromic element, which is the main research and development direction of the present invention

Abstract

The invention relates to a method of driving an electrochromic device. Through detecting signals (such as temperature, time, power and current values) generated during the electrochromic process of an electrochromic element and driving the voltage value of the electrochromic element according to signal changes, the control mechanism can enable multi-stage voltage driving, and thus, when the electrochromic process of the electrochromic element is controlled repeatedly, the color of the electrochromic element is more uniform, the electrochromic time can be shortened, and the service life of the electrochromic element can be prolonged.

Description

technical field [0001] The present invention relates to a method for driving an electrochromic element, in particular to a method for making the color changing performance of the electrochromic element more uniform, shortening the color changing time and prolonging the service life. Background technique [0002] Electrochromic materials (electrochromic materials) are color changes caused by changes in the applied electric field, resulting in reversible changes in the redox state to present different absorption spectrum changes; therefore, electrochromic can also be called electrochromic, Moreover, the electrochromic material exhibits color differences due to different redox states. Therefore, the element composed of electrochromic elements can control its color or penetration change by operating voltage. When driven by voltage, the electrochromic element can be colored (coloured). When the applied potential is stopped The ions will slowly diffuse away from the color-changin...
