Abstract
The utility model discloses an adjustable-color-gradation printing type flexible display screen which at least comprises a printing substrate layer and a printing ink layer that adheres on the printing substrate layer. A transparent electrode layer A and a transparent electrode layer B adhere on the printing ink layer. An electric control light switch layer is provided between the transparent electrode layer A and the transparent electrode layer B, and furthermore the three layers are laminated. A power supply which can adjust output voltage is also provided between the transparent electrode layer A and the transparent electrode layer B. Furthermore the transparent electrode layer A and the transparent electrode layer B are respectively connected with two poles of the power supply. The flexible display screen provided by the utility model has the following advantages: easy colorizing, high response speed, low driving voltage, and high suitability for reading by human eye, adjustable color gradation, and facilitation for the user.
Description
Technical field
The utility model relates to a kind of print-type flexible display screen, and particularly a kind of flexible display screen of adjustable color range belongs to print field.
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, the advantage of attempting to overcome the shortcoming of aforementioned two class display techniques and keeping them, though new display have flexible media, can quick automatically controlled displaying contents, by reflect ambient light demonstration, low energy consumption, portable these characteristics.Such flexible display can be applied to a plurality of fields such as e-book, automobile, smart card, label, digital signature, display.
Research and development to the reflective flexible display of class paper, at present development is the electrophoretic techniques of the international corporations such as E-Ink, Philip, IBM, Bell Laboratory faster in the world, and the electrophoresis of electric globule (placing 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 is presented two kinds of diverse colors.Although obtained certain progress based on the flexible display screen of electrophoretic at present, also had response speed slow (hundreds of millisecond), be difficult to realize that the series of problems such as colored (will realize colour with different optical filters), production cost height need to solve.
At present more existing research and reports based on the flexible display screen of PDLC, but it is of less types, and function is more single.When people state display screen in the use and since the different time periods or under different places extraneous bright and dark light degree varies, therefore need to adjust according to the light intensity in the external world display level of display screen.But present flexible display screen still can not well be realized above-mentioned functions.(whether as mentioned above may I ask technical problem to be solved in the utility model? if above-mentioned statement is wrong, ask additional modifications! )
Summary of the invention
The utility model provides a kind of adjustable color range print-type flexible display screen, solve the deficiency in the above-mentioned background technology, it not only is easy to colorize, fast response time, low, the suitable human eye reading of driving voltage, has also realized simultaneously the function that color range is adjustable, for the user brings great convenience.
Realize that the technical scheme that above-mentioned purpose of the present utility model adopts is:
A kind of adjustable color range print-type flexible display screen, at least comprise undertake the printing of basalis and the printing ink layer that is attached on the basalis of undertaking the printing of, be attached with transparent electrode layer A and transparent electrode layer B on the printing ink layer, be provided with the electric control optical switch layer between transparent electrode layer A and the transparent electrode layer B, and the three is the layered laminate distribution; Also be provided with the power supply of adjustable output voltage between transparent electrode layer A and the transparent electrode layer B, and transparent electrode layer A is connected with the two poles of the earth of power supply with transparent electrode layer B and is connected.
Transparent electrode layer A and transparent electrode layer B are the ITO conductive film that is carved with electrode matrix, the electrode matrix perpendicular direction of transparent electrode layer A and transparent electrode layer B.
The basalis of undertaking the printing of is collapsible and printable flexible insulating material.
Printing ink layer is the CMYK colored ink dot matrix that produces at the basalis of undertaking the printing of with ink printing.
The electric control optical switch layer is polymer dispersed liquid-crystal film.
Be attached with diffuse reflector on the described transparent electrode layer B, diffuse reflector is matt film or gloss oil with diffuse reflection function.
Be attached with protective seam on the described diffuse reflector.
Be attached with protective seam on the described transparent electrode layer B.
The film that protective seam is avoided damaging for the protection display screen, preferred acrylic resin film or aluminum oxide film.
Compared with prior art, the utlity model has following advantage:
1, the flexible display screen that provides of the utility model adopts the printing-ink technology as black and white and the colored basis that shows, 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 flexible display screen that provides of the utility model is installed voltage controller power source between electric-controlled switch layer (PDLC) two transparent electrode layers up and down, variation along with voltage, the light transmission rate of PDLC also changes thereupon, thereby make ink lay present different color ranges, satisfy the demand of user under different environments for use.
3, each layer of the present utility model adopts film, and the integral thickness of display screen is no more than 5mm, make the display screen quality light, be easy to flexibility.
