Dimming window and manufacturing method thereof

A method for manufacturing a dimming window, comprising:

• forming at least two chambers arranged in a stack, each of the chambers comprising two light-transmitting substrates arranged opposite to each other, the at least two chambers comprising a first chamber and a second chamber;
• forming a dimming structure in the first chamber, and forming a first reflective film in the first chamber and/or the second chamber;
• wherein the thickness of the second chamber is greater than the thickness of the first chamber, and the thickness of the chamber is a distance between two opposite surfaces of the two light-transmitting substrates of the chamber;
• wherein the thickness of the second chamber is 6-20 mm;
• wherein a frame sealing structure is provided between two oppositely arranged light-transmitting substrates within each of the chambers, the frame sealing structure comprises a sealing structure and a spacer, and a hollow structure having an air tightness is formed by bonding the sealing structure, the sealing structure comprising at least two layers of sealant;
• wherein within the first chamber, a distance between an edge of the dimming structure and a side of the frame sealing structure close to the dimming structure is 0.5-5 mm.
