Abstract

The invention relates to a drive mode of electrochromic glass, solves the technical defects that effective driving voltage of both sides of large-area electrochromic glass is too high and effective driving voltage of the middle of the large-area electrochromic glass is low, thus uneven color of the electrochromic glass occurs in the prior art. The drive mode can be divided into a one-group electrode drive mode and a two-group electrode drive mode according to the number of conductive strips. In the one-group electrode drive mode, direct current is applied to a top electrode conductive strip and a bottom electrode conductive strip to perform driving, at least one end of at least one conductive strip of the two conductive strips is provided with a bent portion. In the two-group electrode drive mode, the direct current is applied to two pairs of conductive strips. By changing the number and shape of the conductive strips, an electric effect distance between the top electrode conductive strip and the bottom electrode conductive strip is shortened during driving, thereby effective driving voltage distribution on the electrochromic glass is improved, color uniformity of the large-are electrochromic glass is achieved, and the color-changing speed is increased.

Description

technical field [0001] The invention relates to the field of energy-saving glass, in particular to a driving method of electrochromic glass. By changing the shape structure, layout and voltage driving method of conductive strips, a uniform effective driving voltage distribution is obtained, and the electrochromic glass is greatly improved. The speed at which the glass changes color. Background technique [0002] With the rapid development of modern science and technology, the transformation and development of materials are changing with each passing day. Every innovation of materials is closely related to people's life, especially for functional materials, people's demand is constantly increasing. The phenomenon of discoloration refers to a change in the reaction of a substance to light under the influence of the external environment. This phenomenon generally exists in nature. The reversible discoloration phenomenon means that a substance can change color or restore under...
