The conductive thin film only has one layer of substrate layer, so that the conductive thin film not only has anti-steam and anti-UV functions, but also has the advantages of lower thickness and lower cost. In addition, the utility model also discloses an electrophoretic display.
Description
Technical field
The utility model belongs to the thin film technique field, relates in particular to a kind of conductive film and adopts the electrophoretic display device (EPD) of this conductive film.
Background technology
Current conductive film generally is to be made of one deck substrate layer and one deck conductive layer.But in actual applications; require film to have waterproof, anti-UV(ultraviolet ray in most of situation) and the anti-dazzle function; therefore, a kind of improvement is to paste layer protective layer by tack coat on the substrate layer of above-mentioned conductive film, and protective layer is made of substrate layer and barrier layer.Then the layer structure of described film is successively: protective layer (substrate layer, barrier layer), adhesive linkage, substrate layer, conductive layer.
This film has two-layer substrate layer; and because adopting then middle must the bonding with tack coat of two-layer base material; increased like this thickness of film; and make film and need expend more raw material; in addition; owing to increasing protective layer, increased by one technique and fitted, need the more manpower and materials cost of cost and time cost.
In the display technology field, a kind of display of the novel advanced person of employing conductive film manufacturing that needs quietly comes into vogue, i.e. electrophoretic display device (EPD).Electrophoretic display device (EPD) is widely used in the various electronic equipments because of factors such as its power savings, such as the equipment of reading electronic book, and electronic watch, electronic bill-board etc.The general structure of electrophoretic display device (EPD) is respectively front thin layer from top to bottom in other words from front to back, the electrophoresis liquid layer, and adhesive linkage and metacoxal plate layer, wherein front thin layer namely adopts above-mentioned conductive film.The electrophoresis liquid layer is one deck electrophoresis liquid, to be consisted of by the microcapsules that are dispersed in the One's name is legion in the polymer adhesive, each microcapsules contains suspension and is suspended in the different charged particle of one or more colors in the suspension, also can include the band color in the microcapsules but uncharged particle.When applying electric field to suspension, the particle of different colours can move to different directions by suspension, and then can demonstrate different pattern and different color at front thin layer.This display based on microcapsules is very responsive for steam; the infiltration of outside steam will have a strong impact on display effect and the life-span of display; therefore must adopt the band waterproof; further band is prevented UV; the film on the barrier layer of anti-dazzle; but use above-mentioned conductive film; because its conductive film has increased protective layer; and then one deck substrate layer and one deck adhesive linkage have been increased; to seriously reduce the transmitance of display like this; and electrophoretic display device (EPD) comes displaying contents by reverberation; the size of reflectivity is very great for the impact of display effect; reduced reflectivity and then need to improve reflectivity at the electrophoresis liquid layer and compensate because increasing one deck substrate layer and one deck adhesive linkage on the conductive film; but this compensation work is a very complicated technology, does not also have the very good and very ripe technology of effect to solve this problem at present.
The utility model content
