Abstract

The invention discloses a material of a reflecting layer of an electrochromic mirror. The material is characterized in that a used reflecting film is a silver alloy reflecting film, and the work function of the silver alloy is not greater than 4.2eV; a related electrochromic device is manufactured by a negative electrode of an LCD or an LED device or an OLED device, a positive electrode which is glass plated with ITO or transparent conductive film, a frame gel which is epoxy resin, an electrochromic material which is filled in a cavity and UV gel which is dispensed for sealing. The material of the conductive reflecting layer has good performance, higher reflectivity and stability, meanwhile, the material reduces contact potential barrier between the electrode and the electrochromic material, reduces the drive voltage, improves electrochromism efficiency and prolongs the service life of the devices; furthermore, the silver alloy with good performance is taken as the conductive reflecting film to provide the electrochromic device with stable performance.

Description

technical field [0001] The invention relates to a reflective layer material and an assembly thereof in the construction of an electrochromic mirror, which are mainly used in automobile anti-glare rearview mirrors, smart windows, liquid crystal display panels, LEDs and other related fields. Background technique [0002] The electrochromic device refers to the reversible change of the optical properties of the color-changing material under the drive of the applied voltage, and the change of coloring and fading will appear in the color, and the purpose of dimming can be realized according to the contrast of coloring and fading (see 200610049671.2). Compared with the traditional CRT display technology, the electrochromic device has a very low driving voltage and features such as adjustable color. More importantly, the ultra-clear contrast and wide viewing angle of electrochromic devices will become one of the mainstreams of the new generation of paper-type flat panel displays. ...
