preparation example Construction

[0034] As a specific embodiment of the preparation method of the electrochromic device provided by the present invention, it includes the following steps:

[0035] Step S100, depositing a first conductive layer on the surface of the first substrate by using a coating process.

[0036] Step S200, depositing a first electrochromic layer on the surface of the first conductive layer with a mask.

[0037] In step S300, an electrolyte layer and a second conductive layer are sequentially deposited on the surface of the first electrochromic layer by using a coating process. That is, after the electrolyte layer is deposited on the surface of the first electrochromic layer, the second conductive layer is deposited on the surface of the electrolyte layer. The preparation of the single-layer electrochromic device can be completed. Alternatively, after depositing the second conductive layer on the surface of the second substrate, the second conductive layer and the first electrochromic l...

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to an electrochromic device and its preparation method and application. Background technique [0002] Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo a stable and reversible color change under the action of an external electric field, which is manifested as a reversible change in color and transparency in appearance. Materials with electrochromic properties are called electrochromic materials. Therefore, the electrochromic material has a bistable performance. The electrochromic display device made of the electrochromic material not only does not need a backlight, but after displaying a static image, as long as the content of the displayed image remains unchanged, it will not consume electricity. Electricity. Therefore, it has a good energy-saving effect. Moreover, compared with other disp...
