Double-sided electrochromism device and control method thereof

The invention discloses a double-sided electrochromism device and a control method thereof. The double-sided electrochromism device comprises a forward electrochromism unit used for displaying a front pattern and a reverse electrochromism unit used for displaying a reverse pattern. Wherein the forward electrochromic units and the reverse electrochromic units are alternately arranged and are in one-to-one correspondence with the pixel points. The forward electrochromic unit is used for displaying a front pattern, and the reverse electrochromic unit is used for displaying a reverse pattern, so that the display function of the double-sided electrochromic device is realized. According to the double-sided electrochromism device, the forward electrochromism units and the reverse electrochromism units are arranged alternately, and compared with an existing double-sided electrochromism device in which the forward electrochromism units on one side and the reverse electrochromism units on the other side are stacked and
