Tungsten trioxide is a kind of electrochromic material that can be prepared by vacuum co-evaporation method, magnetron sputtering method, vacuum electron beam evaporation method, electroless plating method, anodic oxidation method, chemical vapor deposition method and sol-gel method, which can be used to prepare a window type electrochromic device.

Large area smart device can be prepared using tungsten trioxide film as an electrochromic layer material. While there are uneven discoloration problem in the production of these large-area electrochromic devices. How to solve the problem of uneven discoloration of large-area electrochromic devices? Experts propose the following options:

Tungsten trioxide can be applied for producing a reflective electrochromic device. As you may have known, tungsten trioxide film can be used to prepare an electrochromic glass and has been widely used in automotive anti-glare rearview mirrors, side windows and skylight windows, aircraft portholes, architectural exterior glasses, and display screens. But do you know where the tungsten oxide reflective electrochromic devices can be used?

Tungsten oxide film can be used to produce a large area smart device. We all know that the electrochromic performance of small-sized electrochromic devices is very uniform. But, when the size of electrochromic devices continues to increase, significant discoloration unevenness occurs, which has greatly plagued the application scenarios of large-sized electrochromic devices. But why is there discoloration unevenness in large-area electrochromic devices of tungsten oxide?
