Description

technical field [0001] The invention belongs to the technical field of electrochromism, and relates to a color-changing device and a control method thereof. Background technique [0002] How to control the zonal discoloration of electrochromic devices (that is, the case where the transmittances of different regions are inconsistent) is the focus of electrochromic products. Generally, the conductive layers of different regions are separated to realize the control of different regions. However, in the prior art, once the conductive layers are separated, the discolored regions are fixed and cannot be adjusted according to the needs of practical applications. [0003] At the same time, the electrochromic device can further adjust the light intensity by adjusting the transmittance of the device. Usually, the entire electrochromic device is in a specific transmittance state, that is, the transmittance of each point on the device is the same, and a graded state cannot be achieved...
