Electrochromic Devices and Electronics

Abstract

The invention discloses an electrochromic device and electronic equipment. The electrochromic device includes an electrochromic material, a first conductive layer, a second conductive layer and a driving module. The first conductive layer and the second conductive layer are respectively arranged on two sides of the electrochromic material. The first conductive layer is provided with a plurality of first electrodes at intervals along the circumferential direction. The second conductive layer is provided with a plurality of second electrodes at intervals along the circumferential direction. The driving module is used for applying a first voltage to the first electrode and the second electrode in a preset sequence to color the electrochromic material. In the electrochromic device of the embodiment of the present invention, multiple first electrodes and multiple second electrodes are sequentially time-divided to apply voltages, so that the position of the conductive layer connected to the power supply changes with the order in which the electrodes are turned on, thereby conducting electricity. The voltage difference at each position of the layer on the plane changes with the sequence of electrode conduction, reducing the stable lateral migration of ions in the electrochromic material and avoiding the layering reaction of the electrochromic material charged for a long time.

Description

technical field [0001] The invention relates to the technical field of consumer electronics, and more specifically, to an electrochromic device and electronic equipment. Background technique [0002] In the prior art, electrochromic devices can undergo reversible color changes under the action of an applied electric field. Among them, electrochromic devices can change the color of electrochromic materials by applying voltage to the electrode pairs on both sides of the electrochromic materials. Transmittance, which allows electrochromic materials to switch between a transparent state and a colored state. However, the conductive layer of the electrochromic material has a square resistance, and the voltage difference at each position on the plane is different.

However, the conductive layer of the electrochromic material has a square resistance, and the voltage difference at each position on the plane is different. A large area of ​​the electrochromic material will be charged for a long time, which will cause the ions of the electrochromic material to migrate laterally.

When the electrochromic material achieves rapid fading, after the material reacts quickly in the vertical space, the electrochromic material cannot quickly migrate laterally, and eventually the problem of delamination occurs
