[0028] Please refer to figure 1 , The electrochromic device provided in the embodiment of the present invention includes a conductive substrate 1 , a photoresist layer 2 , a color changing layer 3 and a conductive gel layer 4 . The photoresist layer 2 is disposed on the conductive substrate 1, the photoresist layer 2 is provided with a first pattern groove 21, the color changing layer 3 is embedded in the first pattern groove 21, and the conductive gel layer 4 is provided with a first pattern groove 21. A plurality of second protrusions 41 corresponding to the pattern grooves 21 . The conductive gel layer 4 covers the photoresist layer 2 , and the end surfaces of the plurality of second protrusions 41 are in contact with the surface of the color-changing layer 3 .

[0029] The conductive substrate 1 includes a conductive layer 12 and a transparent substrate 11 ; the transparent substrate 11 is a glass or a flexible substrate; the conductive layer 12 is formed of a metal oxide...

[0048] The difference between the electrochromic device provided by the second embodiment of the present invention and the above-mentioned first embodiment is that in this embodiment, as image 3 As shown, the color-changing layer 3 also covers a plurality of first protrusions 23 disposed on the photoresist layer. Since the photoresist layer is not conductive, and the thickness of the portion of the color-changing layer 3 disposed in the first pattern groove 21 is lower than that of the first The height of the pattern groove 21, that is, the part of the color-changing layer 3 disposed in the first pattern groove 21 does not contact the part of the color-changing layer 3 disposed on the top of the plurality of first protrusions 23; The part of the discoloration layer 3 on the top of the protrusion 23 is not discolored.

[0049] In view of this, when making the color-changing layer 3, the material of the color-changing layer 3 is first dropped on the top of the plurality of firs...

[0053] The electrochromic device provided by the third embodiment of the present invention is: on the basis of the above-mentioned first embodiment or the second embodiment, a tin-plated indium oxide ( ITO) glass 5, and a tin-coated indium oxide (ITO) glass 5 can also be provided on the surface of the transparent substrate 11 on the side away from the conductive layer 12, please refer to Figure 4 , Figure 4 On the basis of the electrochromic device provided in the second embodiment, the upper and lower surfaces are both provided with tinned indium oxide (ITO) glass 5 .

[0054] The electrochromic device of this embodiment is connected to the positive electrode or the negative electrode by the tin-plated indium oxide (ITO) glass 5 on both sides, and the electrodes connected by the two are inconsistent, that is, one is connected to the positive electrode and the other is connected to the negative electrode. The conductive gel layer 4 itself can conduct electricity, and the co...

Abstract

The invention discloses an electrochromic device, comprising a conductive substrate, a photoresist layer, a discoloration layer and a conductive gel layer, wherein the photoresist layer is arranged on the conductive substrate, and the photoresist layer is provided with a first pattern groove, the color changing layer is embedded in the first pattern groove, the conductive gel layer is provided with a plurality of second protrusions corresponding to the first pattern groove, the The conductive gel layer covers the photoresist layer, and the end faces of the plurality of second protrusions are in contact with the surface of the color changing layer. The invention also discloses a manufacturing method of the electrochromic device, which is used for manufacturing the above electrochromic device. The photoresist layer is covered by the conductive gel layer, and the end faces of the plurality of second protrusions are in contact with the surface of the color-changing layer, thereby reducing the thickness of the electrochromic device.

Description

technical field [0001] The invention relates to the technical field of electrochromic devices, in particular to an electrochromic device and a manufacturing method thereof. Background technique [0002] Electrochromic device (ECD, electrochromic device) refers to that under the action of alternating positive and negative voltage, the transmittance, absorptivity, and reflectance of the device also change regularly, and the appearance shows the color change of the device. Electrochromic devices are often used in transparent windows, anti-glare rearview mirrors, military camouflage and flexible wearable devices of transportation vehicles and buildings such as aircraft, automobiles, and high-speed rail. For example, the intelligent color-changing window used in buildings controls the transmittance of the window to the light by applying voltage, which can realize the regulation of the heat entering the room by the sunlight, thereby controlling the indoor temperature and effective...
