Electrochromic device and electronic device

Abstract

The invention discloses an electrochromic device and an electronic device. The electrochromic device comprises an electrochromic material, a first conductive layer, a second conductive layer, and a drive module. The first conductive layer and the second conductive layer are respectively disposed at the two sides of the electrochromic material. A plurality of first electrodes are arranged along thecircumferential direction of the first conductive layer at intervals; and a plurality of second electrodes are arranged in the circumferential direction of the second conductive layer at intervals. The drive module is used for applying first voltages on the first electrodes and the second electrodes according to a preset sequence to realize coloring of the electrochromic material According to theelectrochromic device in the embodiment of the ivnention, voltages are applied to the plurality of first electrodes and the plurality of second electrodes successively in a time-division manner and thus the position of the connected power supplies of the conductive layers change with the electrode conduction sequence, so that voltage differences of the conductive layers at all positions on the plane change with the electrode conduction sequence. Therefore, electrochromic material ions make horizontal migration stably, so that a phenomenon of a layering reaction caused by long-time electrification of the electrochromic material is avoided.

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
