With reference to figure 2, the schematic diagram of the conductive film layer of a kind of light modulation film provided for the utility model embodiment, conductive film layer of the present utility model can realize multiple bandwagon effect, and shows according to project content or setting program, add Consumer's Experience, improve bandwagon effect.
The utility model embodiment provides a kind of light modulation film, this light modulation film comprises: the first conducting film 110, second conducting film 120 and Presentation Function layer 130, wherein, first conducting film 110 and the second conducting film 120 are oppositely arranged, and Presentation Function layer 130 is filled between the first conducting film 110 and the second conducting film 120.
First conducting film 110 is made up of n the first separate subregion 112, and n the first subregion 112 is close to each other and not overlapping, any one first subregion 112 has first electrode 111, wherein, n be more than or equal to 2 integer.Second conducting film 120 is made up of n the second separate subregion 122, and the second subregion 122 and the first subregion 112 are oppositely arranged, and any one second subregion 122 have second electrode 121.
In the present embodiment, the material of Presentation Function layer 130 preferably liquid crystal/polymer composite material.The material of the first conducting film 110 and the second conducting film 120 can be ITO conducting film, and ITO conducting film conductive capability is strong, transmitance is high.At this, whole the first conducting film 110 is divided into individual the first separate subregion 112 of n, therefore any two the first subregions 112 are not overlapping, the physical property segmentation of the first conducting film 110 can't affect its electric conductivity, in order to realize the zonal control of light modulation film, at this, also need to arrange the first electrode 111 on each first subregion 112, thus, any one first subregion 112 has the first electrode 111.After the first conducting film 110 is divided, the second conducting film 120 be oppositely arranged to the first conducting film 110 also carries out corresponding segmentation, define individual the second separate subregion 122 of n, second subregion 122 arranges the second electrode 121, thus, after conductive film layer on light modulation film is divided, by the partition shapes after partitioning scheme and segmentation, the display and control to light modulation film zones of different can be realized.
