Embodiment 1

[0066] The billboard component 10 , the electrochromic device 20 and the regulation module 30 are assembled.

[0067] Making the electrochromic device 20 includes:

[0068] (1) WO 3 Nano film 5 material electrochromic electrode preparation:

[0069] a. Magnetron sputtering a fluorine-doped tin oxide (FTO) film 2 on the surface of tempered glass 1 with a specific size, with a thickness of about 320nm;

[0070] b. Perform high-temperature annealing treatment on it to obtain FTO conductive glass with higher strength, then ultrasonically clean the FTO conductive glass for 15 minutes in the order of ultrapure water, acetone, and ethanol, and dry it for later use; then, use magnetron sputtering method Coating W film on FTO glass with a thickness of 220nm; W film is used as WO 3 a growth source for the nanowires;

[0071] c. Prepare a 0.2mol / L sodium tungstate aqueous solution, then add 3mol / L hydrochloric acid dropwise until no precipitation occurs, and then dissolve the obtaine...

Description

technical field [0001] The invention belongs to the field of manufacturing, and more specifically relates to an outdoor billboard based on an electrochromic device and a manufacturing method thereof. Background technique [0002] Billboard is a display system for displaying information such as products and services, and generally refers to all media that transmit information. Due to the particularity of its outdoor location, outdoor billboards are required to be able to adjust the brightness of information display according to the intensity of sunlight. However, the existing outdoor billboards are all made of metal, wood, glass and other materials. It is difficult to achieve this function. Contents of the invention [0003] Aiming at the problems existing in the background technology, the present invention provides an outdoor billboard based on an electrochromic device and its manufacturing method, which improves the structure and manufacturing process of the self-powered...
