Electrochromic Device

摘要

In an electrochromic device, upper and lower electrodes are formed respectively on upper and lower substrates, and an electrochromic laminate is sandwiched between upper and lower central regions of the upper and lower electrodes. A looped spacer is disposed between the upper and lower electrodes to surround the electrochromic laminate. A rib member extends from the looped spacer and is fitted in a slot of the upper electrode. An upper electrode contact is disposed between the looped spacer and an upper marginal region of the upper electrode. A lower electrode contact is disposed between the looped spacer and a lower marginal region of the lower electrode.

主权项

1. An electrochromic device, comprising:
an upper substrate which is light-transmissive, and which has an upper peripheral edge; a lower substrate which has a lower peripheral edge; an upper electrode which is light-transmissive, which is formed on said upper substrate, and which has an upper central region, an upper marginal region surrounding said upper central region, and a slot formed between said upper central region and said upper marginal region; a lower electrode which is formed on said lower substrate, and which has a lower central region and a lower marginal region surrounding said lower central region; a looped spacer made from an electrical insulating material, and having an upper surface facing said upper marginal region, a lower surface facing said lower marginal region, and an inner peripheral surface interconnecting said upper and lower surfaces; a rib member made from an electrical insulating material, extending upwardly from said upper surface of said looped spacer, and configured to be fitted in said slot, said rib member and said inner peripheral surface cooperatively defining an accommodation space; an upper electrode contact which has an upper contact body disposed between said upper marginal region and said upper surface of said looped spacer, and an upper terminal tab extending from said upper contact body outwardly of said upper marginal region; a lower electrode contact which has a lower contact body disposed between said lower marginal region and said lower surface of said looped spacer, and a lower terminal tab extending from said lower contact body outwardly of said lower marginal region; and an electrochromic laminate disposed in said accommodation space and sandwiched between said upper central region and said lower central region.
