Embodiment Construction

[0015] Please also refer to figure 1 and figure 2 , The electrochromic film 100 according to the embodiment of the present invention includes a first substrate 10 , a first film layer 30 , a second film layer 50 , a second substrate 70 and a dielectric solution 90 . The first substrate 10 , the first film layer 30 , the second film layer 50 and the second substrate 70 are all in the form of transparent films and stacked in sequence. The dielectric solution 90 is accommodated in the first film layer 30 and the second film layer 50 .

[0016] The first substrate 10 is a transparent film, and a plurality of first electrodes 12 arranged in a matrix are formed on one surface thereof. The first electrode 12 is a transparent electrode. In this embodiment, the first electrode 12 is an indium tin oxide (ITO) electrode, which is rectangular, and the first electrode 12 is adhered to the surface of the first substrate 10 by printing. Each first electrode 12 is electrically connected t...

Abstract

An electrochromic film comprises a first substrate, a second substrate and a charged particle containing layer between the first substrate and the second substrate. The side, towards the charged particle containing layer, of the first substrate is provided with multiple first electrodes; the side, towards the charged particle containing layer, of the second substrate is provided with multiple second electrodes, the charged particle containing layer is provided with multiple through holes corresponding to the first electrodes and the second electrodes, the two ends of each through hole correspond to one first electrode and one second electrode respectively, the through holes are step holes and include the first through holes and the second through holes, the first through holes are close to the first electrodes, and the second through holes are close to the second electrodes. The electrochromic film further comprises a dielectric solution contained in the step holes, colored charged particles are scattered in the dielectric solution, and the charged particles can be in different distribution states under the action of an eclectic field between the first electrodes and the corresponding second electrodes. The electrochromic film is simple in structure, can change color locally and has an anti-dazzle function.

Description

technical field [0001] The invention relates to a color-changing film, in particular to a color-changing film capable of changing color after electrification. Background technique [0002] In the field of optical materials, there are generally two types of electrochromic films: one is the electrochromic film that uses the principle of liquid crystal display to change color, and the other is the electrochromic film that uses the principle of oxidation-reduction reaction to change color. In the color-changing film using the principle of liquid crystal display, the liquid crystal is accommodated between two parallel transparent electrodes, and polarizers are arranged on the outside of the two electrodes. The light first passes through the first polarizer and the first electrode, then passes through the gap between the liquid crystals, and then exits from the second electrode and the second polarizer. By changing the direction of the electric field between the electrodes to cha...
