Problems solved by technology

This invention uses patterned ITO to make a transparent conductive layer, so that the response time of the electrochromic glass is reduced, the cycle life is increased, and the color contrast is increased. However, the display effect is single and cannot present a sense of layering or gradient.
[0004] CN103676392A discloses a method for manufacturing a patterned film layer. The manufacturing method includes the following steps: providing a substrate, the substrate has a first surface and a second surface opposite to the first surface; providing a material source, the second surface of the substrate One side faces the material source, and the material source is used to provide a plurality of charged particles; a magnetic element is provided, and the second surface is disposed between the magnetic element and the first surface; and the charged particles are deposited on the first surface by the magnetic element , to form a patterned film layer; the patterned layer prepared by this method has high reliability, but it will cause damage to the substrate, thereby affecting the viewing area

Abstract

The invention provides a patterned electrochromic device, electrochromic glass and an application. The patterned electrochromic device comprises a first conductive layer, an electrochromic layer, an electrolyte layer, an ion storage layer and a second conductive layer which are laminated in sequence, wherein a prefabricated pattern is arranged on the electrochromic layer and/or the ion storage layer; the prefabricated pattern is arranged on the electrochromic layer and/or the ion storage layer, so that the device has the advantages of short color change time, high reflectivity and the like onthe premise that the conventional performance of the device is achieved; in addition, a reflective layer, a protective layer or the conductive layer do not need to be damaged, and the display change of the pattern can be presented with the sense of layering and gradual change through voltage control or under constant voltage; and in addition, a blind spot pattern is arranged on the reflective layer, so that the defect that the preset pattern is arranged on the conductive layer or the glass layer in the prior art and needs to penetrate all elements is overcome, patterning with closed elements can be preset, and a breakpoint compatibility effect of a blind spot display technology can be realized.

Description

technical field [0001] The invention belongs to the technical field of electrochromism, and relates to a patterned electrochromic device, electrochromic glass and applications. Background technique [0002] Currently, electrochromic products on the market are expensive, such as electrochromic rearview mirrors, sunroofs, glass curtain walls and other products. Moreover, electrochromic products on the market cannot make various patterns on the color-changing layer due to technical limitations, such as the warning words on the current electrochromic rearview mirror, the auxiliary heating icon for lane change, and the method of destroying the reflective layer by etching or silk screen printing Realized, reduced field of view. At present, it has been proposed to use a color-changing solid film as an electrochromic product for the color-changing layer. Based on solid-state electrochromic technology, we can preset patterns on a specific color-changing layer without destroying the ...
