Abstract

The invention discloses an electrochromic device, a control method thereof, electronic equipment and a storage medium. The electrochromic device comprises an electrochromic material and an electrode pair electrically connected with the electrochromic material. The control method comprises the steps of: applying a first voltage to the electrochromic material to color the electrochromic material; applying a second voltage to the electrochromic material after the electrochromic material is colored to discolor the electrochromic material, wherein polarities of the second voltage and the first voltage are opposite; and applying a third voltage to the electrochromic material after applying the second voltage to the electrochromic material for a predetermined period of time, so that the transmittance of the electrochromic material is higher than a set value, polarities of the third voltage and the first voltage are opposite, and the magnitude of the third voltage is less than the magnitude ofthe second voltage. The control method, the electrochromic device, the electronic equipment and the storage medium can prevent re-coloring while rapidly discoloring the electrochromic material by applying the third voltage after applying the second voltage reversely for a period of time.

Description

technical field [0001] The present application relates to the technical field of consumer electronics, and more specifically, to an electrochromic device, a control method thereof, electronic equipment and a storage medium. Background technique [0002] In related technologies, electrochromic devices can undergo reversible color changes under the action of an external electric field, wherein the electrochromic device can change the color of the electrochromic material by applying a voltage to the electrode pairs on both sides of the electrochromic material. Transmittance, which allows electrochromic materials to switch between a transparent state and a colored state. After the electrochromic material is colored, the electrochromic material can be faded by disconnecting the electrode pair, short-circuiting the electrode pair, or applying back pressure to the electrode pair, but the fading speed is relatively slow. How to control electrochromic devices to realize rapid fading...
