The basic layer is composed of the aluminized layer and the flexible electrode layer, wherein the aluminized layer and the flexible electrode layer are stacked up and down. The printed ink layer is printed on the aluminized layer. The aluminized layer is composed of a paper base and aluminum films attached to the front and back of the paper base. A magnifier layer, the electronic control switch layer and the electrode layer are sequentially attached to the upper portion of the printed oil ink layer from bottom to top. The printed type flexible display screen based on the aluminized layer is easy to achieve colorization and flexibility, high in reflectivity, short in response time, low in driving voltage, simpler in structure and a manufacturing technology, low in production cost, and more suitable for eye reading due to the fact that display is achieved by reflections of natural lights.
Description
Technical field
The utility model relates to a kind of print-type flexible display screen, belongs to print field, also belongs to electronic applications.
Background technology
Present display technique can be divided into two large classes: a class is that papery shows that its principal feature is: come displaying contents by reflect ambient light, be easy to colored the demonstration, and angle of visibility large (near 180 °), medium is soft.Another kind of is the electronical displays such as CRT, LCD, LED, and its principal feature is: but the information fast refresh relies on display self internal illumination to come displaying contents, need to consume more electric energy during work, makes easily the people tired during reading, and medium is not soft.
People are putting forth effort to develop the reflective flexible display of class paper (being commonly called as Electronic Paper) over past ten years, attempt to overcome the shortcoming of aforementioned two class display techniques and the advantage that keeps them.Development is E-Ink faster in the world at present, Philip, IBM, the reflective flexible display of class paper based on electrophoretic techniques of the international corporations such as Bell Laboratory, the electrophoresis of electric globule (place microcapsules or little cup) under electric field action that its displaying principle is based on different colours (being white and black at present basically) moves sight line the reflection of external ambient light presented two kinds of diverse colors, but also there is response speed slow (hundreds of millisecond) in this class display screen, be difficult to realize colored (will realize colour with different optical filters), a series of problems that need solution such as production cost height.
Summary of the invention
The utility model provides a kind of print-type flexible display screen based on aluminium coated, has solved above-mentioned deficiency of the prior art, and it not only is easy to colorize, fast response time, cost is low, manufacturing process is relatively simple, be fit to large-scale production.And its reflectivity is high.
Realize that the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of print-type flexible display screen based on aluminium coated, at least comprise electrode layer, electric-controlled switch layer, basic unit and be attached to printing ink layer in the basic unit, described basic unit is comprised of aluminium coated and the flexible electrode layer of stacked on top of one another, printing ink layer is undertaken the printing of on aluminium coated, and described aluminium coated is comprised of paper substrate and the aluminium film that is attached on the paper substrate tow sides; The top of printing ink layer is attached with magnifier layer, electric-controlled switch layer and electrode layer from bottom to up successively.
Be attached with diffuse reflector on the described electrode layer, diffuse reflector is matt film or the gloss oil layer with diffuse reflection function.Be attached with protective seam on the diffuse reflector, protective seam is acrylic resin thin layer or aluminum oxide film rete.
Described electrode layer is for being the ITO conductive film that is carved with electrode matrix.
Described printing ink layer is for producing the printing ink layer of Huang, magenta or cyan ink dot matrix at aluminium coated with the UV ink printing.
Described electric control optical switch layer is the polymer dispersed liquid-crystal film layer.
The thickness of described display screen is no more than 5mm.
The print-type flexible display screen based on aluminium coated that the utility model provides has following advantage:
What 1, the utility model provided adopts the printing-ink technology as black and white and the colored basis that shows based on the print-type flexible display screen of aluminium coated, adopts fm screening mode ripe in the printing technology, can obtain higher resolution, improves output accuracy.Utilize simultaneously the color vision mixing principle in the printing, obtain various colors by the stack of printing dot matrix reflected light, the colored solution technology that shows is comparatively ripe, and implementation method is effectively simple and gradation is abundant.
2, the print-type flexible display screen based on aluminium coated that provides of the utility model is as electric control optical switch with Polymer Dispersed Liquid Crystal (PDLC) film, response time can shorten within the 40ms, driving voltage can be reduced to 25v, obviously is better than the E-INK technology (response time is about 150ms, driving voltage is about 90v) of present main flow.In addition, the PDLC film does not need polaroid, exists and preparation technology easily realizes with the solid film form, is applicable to the technological process of roll-to-roll (Roll-to-Roll) continuity, and manufacture craft is simple, and production cost is low, is fit to large-scale production.And with the display screen of electro-optic crystal as electric control optical switch, although the response time is short, driving voltage higher (being about 443v), and the complicated process of preparation of solid film, cost is high.By comparison, display screen of the present utility model all has clear superiority at aspects such as driving voltage, manufacture craft and production costs.
3, adopt at present the TFT substrate as the display screen of electrode, because the TFT substrate is a thin film transistor (TFT), not only complex structure, cost are high, and mainly are applicable to the transmissive operation mode of backlight.And display screen of the present utility model is to adopt the ITO conductive film as control electrode, structure is more simple, cost is low, realize showing by natural reflection of light, do not need special light source, more meet the human eye reading habit, the gloss oil that adopts in addition matt film or have a diffuse reflection function is as diffuse reflector, can eliminate reflectively, improve contrast, improve and read comfort level.
4, flexible electrode layer of the present utility model, aluminium coated, electrode layer, electric control optical switch layer and diffuse reflector and protective seam etc. adopt films, and the integral thickness of display screen is no more than 5mm, make the display screen quality light, be easy to flexibility.
Description of drawings
The structural representation based on the print-type flexible display screen of aluminium coated that Fig. 1 provides for the utility model;
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed specific description.
The utility model provide based on the structure of the print-type flexible display screen of aluminium coated as shown in Figure 1, printing ink layer is attached in the basic unit, basic unit is comprised of aluminium coated and the flexible electrode layer of stacked on top of one another, printing ink layer is undertaken the printing of on aluminium coated, and described aluminium coated is comprised of paper substrate and the aluminium film that is attached on the paper substrate tow sides; The top of printing ink layer is attached with magnifier layer, electric-controlled switch layer and electrode layer from bottom to up successively.Be attached with diffuse reflector on the described electrode layer, be attached with protective seam on the diffuse reflector.The integral thickness of this display screen is no more than 5mm.
