Dimming panel, method for manufacturing same, method for driving same, and architectural dimming glass

A dimming panel, provided with a dimming region and a peripheral region on one side of the dimming region, wherein the dimming panel comprises:

• a first base substrate and a second base substrate opposite to each other;
• a first electrode layer on one side of the first base substrate facing the second base substrate and at least in the dimming region;
• a plurality of support columns on one side of the first electrode layer facing the second base substrate, wherein an orthographic projection of each of the support columns on the first base substrate is provided an overlapping region with an orthographic projection of the first electrode layer on the first base substrate;
• a transition layer between the first electrode layer and the support columns;
• a second electrode layer on one side of the second base substrate facing the first base substrate, wherein an orthographic projection of the second electrode layer on the first base substrate at least covers an orthographic projection of the first electrode layer in the dimming region;
• a dimming layer between the second electrode layer and the transition layer;
• a conductive portion in the peripheral region;
• a third electrode layer on the first base substrate and in the peripheral region;
• wherein the third electrode layer is insulated from the first electrode layer, and the third electrode layer is electrically connected to the second electrode layer through the conductive portion;
• a sealant in the peripheral region, wherein the conductive portion is multiplexed as the sealant;
• and
• a first orientation layer on one side of the transition layer facing the dimming layer;
• wherein the transition layer is between the first orientation layer and the first electrode layer, and the transition layer fills a gap between the first electrode layer and the third electrode layer to cause that the third electrode layer is insulated from the first electrode layer.
