In recent years, along with the fast development of science and technology, people, by terminals such as computer, Digital Television, mobile phone, panel computers, enjoy new media service, electronics read the newspaper the new reading method such as periodical, Quick Response Code reading.The appearance of e-book causes people to pay close attention to greatly, wherein especially extensively concerned with the e-book of electric ink.This e-book can provide a kind of texture and the reading experience that are similar to traditional books, makes eye be not easy fatigue; Meanwhile, electric ink is color development by reflects natural light, even if be in strong illumination, screen also there will not be the reflective situation do not seen.And this e-book no longer needs to consume more electricity, the only consumes power when page layout switch, therefore increases flying power and the serviceable life of battery.
With regard to the habits and customs of current people, pure electronic display cannot meet the requirement of people, market has also occurred electric ink touch screen at present, as the kindle e-book of Amazon.But existing touch panel and electric ink display screen separate, if touch panel is placed in the former mode above electric ink, physical space is there is between electric ink display and touch panel, therefore, electric ink display above and touch panel below between can reflecting extraneous light line etc., cause the visuality reduction under the environment become clear in outdoor etc.
Therefore a kind of touch panel parts and electronic ink display panel is needed to realize integrated electric ink touch screen.
Summary of the invention
In view of this, technical matters to be solved by this invention is to provide a kind of touch panel parts and realizes integrated electric ink touch screen with electronic ink display panel.This electric ink touch screen, using Graphene as the critical material of touch screen, realizes ultra-thin electric ink touching display screen with a kind of similar in-cell structure.
The object of the present invention is achieved like this:
A kind of in-cell electric ink touching display screen provided by the invention, comprises contact panel and electronic display; Described contact panel is arranged at touch panel parts and electronic ink display panel integrator electric ink touch-control screen structure in electronic display.
Further, described electronic display comprises base material, film conductive layer, electronic ink layer, touch layer, pixel electrode layer, baseplate material.
Described baseplate material is arranged electrode pixel layer; Described electrode pixel layer arranges touch layer; Described touch layer arranges electronic ink layer; Described electronic ink layer arranges film conductive layer; Described film conductive layer arranges base material.
Further, described contact panel is arranged between electronic ink layer in electronic display and electrode pixel layer.
Further, described film conductive layer is graphene film transparency conducting layer.
Further, described contact panel is embedded in electronic display by contact panel by in-cell technology.
Present invention also offers a kind of in-cell electric ink touching display screen preparation method, comprise the following steps:
Flexible TFT and substrate are saved and carries out being combined to form TFT substrate;
Graphene is transferred to TFT substrate on the surface;
At graphene edge printing silver slurry;
By laser ablation TP circuit;
By binding, FPC is fixed on the tft substrate;
By in the PET base material of Graphene transition zone sclerosis protective seam;
In PET base material, then coating electronic ink toasts electric ink;
In PET base material, TFT substrate is carried out hot pressing synthesis by glue coating.
Further, described electronic ink layer is coated on transparent electrode layer by blade coating, spin coating or roll coating model.
Beneficial effect of the present invention is: touch panel embeds in electronic ink screen by the present invention, and the number of plies that light will penetrate reduces, and image sharpness strengthens.As when tearing mobile phone one block protection film, immediately feel that high screen definition is many, also more outstanding Electronic Paper, close to the visual angle of 180 degree, strengthens readability simultaneously; Although the production difficulty of the embedded screen of touch panel is larger, also reduces screen each layer bonding time, accelerate production efficiency; The screen of preparation is thinner, and screen is thin, can improve the more flexible degree of screen to a certain extent, and screen is thin on the other hand, is equivalent to space larger, can the vacating space larger battery of contribution or other abundanter utility appliance.Should " in-cell " electric ink touching display screen, the structure of its uniqueness will bring the reading interest of reading experience that people upgrade and excitation people, believes and more people can be redirected on this road of liking reading
