Electrochromic device and electrochromic apparatus

Abstract

This application relates to the field of electrochromic technology, and provides an electrochromic device and an electrochromic apparatus. The electrochromic device includes a first conductive substrate layer, an electrochromic layer, and a second conductive substrate layer stacked sequentially. The electrochromic device has an edge region defined by a first edge line and a second edge line. A plurality of grooves are provided in the edge region, each groove penetrating the electrochromic layer and penetrating at least one of the first and second conductive substrate layers. The orthographic projection of each groove onto the plane of the electrochromic layer has at least one inner rounded corner and at least one outer rounded corner. The inner rounded corner is located at the first edge line of the edge region, and the outer rounded corner is located at the second edge line of the edge region of the electrochromic device. The at least one inner rounded corner is larger than the adjacent outer rounded corner, which sets the rounded corner size of the inner corner to a larger extent, thereby reducing the number and size of cracks at the inner rounded corner and improving the reliability of the product.
