Detailed ways

Electrochromism refers to the phenomenon that the optical properties of materials (such as reflectivity, light transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of an applied electric field. Electrochromism manifests itself as a reversible change in the color and transparency of a material. Materials with electrochromic properties may be referred to as electrochromic materials. A device unit made of electrochromic material may be referred to as an electrochromic unit 111 .

Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of an electrochromic unit provided in an embodiment of the present application. The electrochromic unit 111 may include a first conductive layer 1111 , a color changing layer 1112 , an electrolyte layer 1113 , an ion storage layer 1114 and a second conductive layer 1115 stacked up. The first conductive layer 1111 and the second conductive layer 1115 are located at two ends of the electrochromic unit 111 .

The first conductive layer 1111 and the second conductive layer 1115 may be transparent conductive layers with excellent electrical conductivity and good optical transparency. The transparent conductive layer may be indium tin oxide (ITO), tin oxide (SnO ₂ ) or antimony tin oxide (ATO) and the like.

The color-changing layer 1112 is the core layer of the electrochromic unit 111 and also the layer where the color-changing reaction occurs. The material of the color-changing layer 1112 can be classified into inorganic electrochromic materials and organic electrochromic materials according to types. The inorganic electrochromic material may be tungsten trioxide (WO ₃ ) or nickel oxide (NiO). The organic electrochromic materials mainly include polythiophenes and their derivatives, viologens, tetrathiafulvalenes, metal phthalocyanines and the like.

The electrolyte layer 1113 is composed of special conductive materials, such as liquid electrolyte materials containing lithium perchlorate, sodium perchlorate, etc., or solid electrolyte materials.

The ion storage layer 1114 plays the role of storing charges in the electrochromic unit 111, that is, stores corresponding counter ions when the material of the color-changing layer 1112 undergoes a redox reaction, thereby ensuring that the entire electrochromic unit 111 charge balance.

Please refer to FIG. 2 . FIG. 2 is a schematic structural diagram of an electrochromic component provided in an embodiment of the present application. This embodiment provides an electrochromic component 11 . The electrochromic component 11 includes the electrochromic unit 111 and a voltage control circuit 112 . The voltage control circuit 112 is electrically connected to the electrochromic unit 111 , and the voltage control circuit 112 adjusts the driving voltage of the electrochromic unit 111 to adjust the color of the electrochromic unit 111 . When the driving voltage of the electrochromic unit 111 is the first voltage, the electrochromic unit 111 has a first light transmittance, and the color of the electrochromic unit 111 is the first color. When the driving voltage of the electrochromic unit 111 is the second voltage, the electrochromic unit 111 has a second light transmittance, the first light transmittance is greater than the second light transmittance, and the electrochromic unit 111 has a second light transmittance. The color of the color changing unit 111 is the second color. The first conductive layer 1111 and the second conductive layer 1115 are located at both ends of the electrochromic unit 111 , and the voltage control circuit 112 is electrically connected to the first conductive layer 1111 and the second conductive layer 1115 .

When a certain voltage is applied to both ends of the electrochromic unit 111 , the material of the color-changing layer 1112 of the electrochromic unit 111 undergoes a redox reaction under the action of the voltage, thereby changing color.

For example, when the driving voltage applied to the electrochromic unit 111 changes from 0V to 0.8V, the electrochromic unit 111 may change from yellow to red. When the driving voltage applied to the electrochromic unit 111 changes from 0.8V to 1.3V, the electrochromic unit 111 can change from red to blue. When the driving voltage applied to the electrochromic unit 111 changes from -1.4V to 1.6V, the electrochromic unit 111 can change from colorless to dark blue.

In some embodiments, the electrochromic unit 111 with different characteristics can be obtained by designing different polymers as the material of the color-changing layer 1112 . Some of the electrochromic units 111 may have the following characteristics: when a certain voltage is applied to change the electrochromic unit 111 to a certain color, even if the voltage is removed, the electrochromic unit 111 can still maintain the color for a long time. the color. For example, when a voltage of 1.6V is applied, the electrochromic unit 111 turns blue, and after the voltage is removed, the electrochromic unit 111 can still keep blue for more than 24 hours.

As shown in FIG. 3C , the first semi-finished product M1 and the second semi-finished product M2 are bonded, wherein the discoloration layer 1112 is bonded to the electrolyte layer 1113 .

Then, the substrate of the electrochromic unit 111 can be cut, and the substrate of the electrochromic unit 111 is cut into the electrochromic unit 111 of 1 mm×1 mm, and then the electrochromic unit 111 for packaging, wherein the electrochromic units 111 are arranged in an array, an isolation layer is used between the electrochromic units 111 for insulation isolation, and a voltage control circuit is used to connect each of the electrochromic units 111 The first conductive layer 1111 and the second conductive layer 1115 independently control each electrochromic unit 111 to change color through the voltage control circuit, that is, change from an initial state to a color changing state. For example, the initial state is white, and the discoloration state is red; for another example, the user can set the initial state and discoloration state by himself, setting the initial state to yellow, and setting the discoloration state to blue.
