Comparative example 1
The only difference from embodiment 1 is that a predetermined pattern is provided on the first conductive layer or the second conductive layer, and the rest of the composition and the preparation method are the same as those of embodiment 1.
The patterned electrochromic device in the comparative example was powered on for reflectivity testing, the testing method was the same as example 1, since the pattern region showed open circuit and no change in reflectivity of the patterned region was measured; and the display effect is not changed by adjusting the voltage; as can be seen from comparison between this comparative example and example 1, when a closed pattern is preset on the first conductive layer or the second conductive layer, the pattern region exhibits a pattern in which an open circuit cannot show a sense of gradation or a sense of gradation.
Comparative example 2
The only difference from example 1 is that a pattern preset by a physical or acid etching chemical method is provided on the reflective layer, and the rest of the composition and the preparation method are the same as example 1.
Electrifying the patterned electrochromic device in the comparative example to perform reflectivity test, wherein the test method is the same as that of the example 1, and the reflectivity of the patterned area is close to zero when the reflecting layer is damaged; and the gradation and gradient of the display effect are found to be poor by adjusting the voltage or under the constant voltage; as can be seen from the comparison of this comparative example with example 1, when the predetermined pattern is provided on the reflective layer, that is, the reflective layer is damaged, the gradation feeling and the gradation feeling of the pattern area display effect are deteriorated.
Comparative example 3
The only difference from example 1 is that a predetermined pattern is provided on the protective layer, and the remaining composition and preparation method are the same as example 1.
The patterned electrochromic device in the comparative example is electrified to carry out reflectivity test, the test method is the same as that of the example 1, and the reflectivity of the patterned area is the same as that of the non-patterned area measured because the protective layer is made of transparent glass xylene and acetone, and patterns cannot be preset on the protective layer; and by adjusting the voltage or under the constant voltage, the display effect can not present the layering sense and the gradual change sense; as can be seen from the comparison of this comparative example with example 1, when the predetermined pattern is provided on the transparent protective layer, the device has no patterning effect.
Example 6
The only difference from example 5 is that the electrochromic layer and the ion storage layer are formed with a predetermined pattern area without filling the black electrochromic material, and the reflective layer is provided with a corresponding blind-spot display icon, and the rest of the composition is the same as example 5.
The patterned electrochromic device in the embodiment is electrified to carry out reflectivity test, the test method is the same as that of the embodiment 1, the reflectivity is close to zero, and the transmittance is more than 80 percent; and the electrochromic device in the embodiment is subjected to a blind spot display test, so that the electrochromic device obtained in the embodiment has a better blind spot display function.
Comparative example 4
The only difference from example 6 is that patterning treatment of the electrochromic layer is not included, and the remaining composition and preparation method are the same as those of example 6.
The patterned electrochromic device in the comparative example is electrified to carry out reflectivity test, the test method is the same as that of the example 1, the reflectivity is close to zero, and the transmittance is less than 40%; carrying out a blind spot display test on the display screen, and finding that the display screen cannot well display the blind spot; as can be seen from the comparison of this comparative example with example 6, when the electrochromic layer was not treated, the device transmittance was seriously affected, and thus a good blind spot display effect could not be obtained.
