The touch screen can be a resistive film touch screen or a capacitive film touch screen. The glass substrate is made of alkali-free glass and is bonded on the hot-melt adhesive layer through hot pressing. The ITO electrode membrane, the electronic ink capsules and the hot-melt adhesive layer form an electronic ink layer. The electronic ink layer is bonded with the glass substrate through the hot-melt adhesive layer. The touch screen is seamlessly bonded on the ITO electrode membrane of the electronic ink layer through optical transparent adhesive. The integrated electronic paper display touch screen has the advantages that the performance is stable, the touch screen is light and thin, the light transmittance is better, the touch screen is simple and feasible to manufacture, the cost is lower and the utilization efficiency of electronic books is improved at the same time.
Description
Technical field
The utility model relates to field of electronic display, especially relates to a kind of Electronic Paper and shows touch-screen.
Background technology
Electronic-paper display screen is a kind of display screen of reflection, by the Ag film, and electronic ink layer, glass substrate is formed.Electronic-paper display screen utilizes electrophoretic display technology (EPD) principle to process; Electrophoretic display technology is that the charged particle with black, white dichromatism is packaged in the micella drop structure, controls the lifting moving of different electric charge black and white particles by extra electric field, to demonstrate the monochromatic display effect of black and white; Under effect of electric field; Two kinds of different particles of black and white are not stopped transport moving, and when the particle of white rose to upper surface, all ambient lightings were mapped to upper surface by reflection fully; So just formed white state, just the state of paper; Behind the exchange electrode, the particle of two kinds of colors can switch, white like this particle just can to below gone, above the particle of black was arrived, light was all absorbed by the particle of black, the result just causes black, has also just formed white and black displays.In addition; At upper surface the state of mixing can be arranged also, two kinds of proportional mixing of different particles can form black and white like this and the different colours of gray-level is arranged; Because the EPD technology can demonstrate the white and black displays effect of high reflectance, high contrast, therefore very be fit to do Electronic Paper.
Say that from know-why touch-screen can be divided into five basic kind: vector pressure sensing technology touch-screen, resistive technologies touch-screen, capacitance technology touch-screen, infrared technology touch-screen, surface acoustic wave technique touch-screen.Be divided into four kinds to touch-screen according to the principle of work of touch-screen and the medium of transmission information, they are respectively resistance-type, infrared-type, capacitor induction type and surface acoustic wave type.The application of resistive touch screen is the most extensive at present.The resistive touch screen major part is a resistance film screen; This is a kind of laminated film of multilayer; As basic unit, the surface scribbles the transparent oxidized metal of one deck ITO coating conductive layer, is stamped one deck outside surface cure process, smooth anti-friction plastic layer above again with one deck glass or duroplasts flat board for it; Its inside surface also scribbles one deck coating, between them, has many tiny transparent isolating points to separate insulation to two conductive layers.When the finger touch screen, two conductive layers has just had contact in the position, touch point, and resistance changes, and on X and Y both direction, produces signal, send touch screen controller then.Controller detects this contact and calculates that (mode according to analog mouse operates again for X, position Y).The most basic principle of Here it is resistive technologies touch-screen.For the four-wire ohm screen, every layer all increased the 5V constant voltage when the two-layer transparent metal layer of four-wire ohm analog quantity technology was worked: a vertical direction, a horizontal direction.Need four cables altogether.
The Electronic Paper of prior art shows that touch panel device fits to touch-screen on the electronic-paper display screen, to realize the touching function.But; The display device that adopts this method to obtain with touching function; Owing to need separately touch-screen to be assembled; This Electronic Paper shows that the Electronic Paper that the production efficiency of touch panel device is low and obtain shows that touch panel device is thicker, is not easy again touch-screen accurately is positioned on the electronic-paper display screen.
The utility model content
To the problems referred to above that prior art exists, the applicant provides a kind of integrated electric paper to show touch-screen.The utility model stable performance, light, thin, light transmission is better, makes simple possible, cost is lower, has improved the service efficiency of e-book simultaneously.
The technical scheme of the utility model is following:
Integrated electric paper shows touch-screen, is followed successively by from bottom to up: glass substrate, hot melt adhesive layer, electric ink capsule, ITO electrode film, touch-screen.Said touch-screen can be resistance film formula touch-screen or capacitance diaphragm touch-screen.Said glass substrate adopts alkali-free glass, is affixed on hot melt adhesive layer through thermocompression bonded; ITO electrode film, electric ink capsule, hot melt adhesive layer are formed electronic ink layer; Electronic ink layer is through hot melt adhesive layer and glass substrate bonding; Touch-screen passes through optical lens gelatin seamless adhesion on the ITO of electronic ink layer electrode film.
The utility model beneficial technical effects is:
The utility model substitutes the Ag film with touch-screen, reduces and uses the Ag film, and structure is simpler; Save the minimum bonding process of production yields; Effectively overcome defective workmanships such as bubble and rainbow line, can better improve product yields level, reduced production costs.When adopting the four-wire ohm touch-screen, the parts in the electric resistance touch screen do not need any moving, and the electric resistance touch screen reaction sensitivity is fine; Be a kind of working environment of isolating fully to external world, be not afraid of dust and steam, can adapt to various rugged environments; Can touch with any object, stability is better.
