Description
Technical field
The present invention relates to a kind of inductive liquid crystal display key screen.
Background technology
Use mechanical key from people, touch MP3, the MP4 in streets and lanes till now, arrive touch mobile phone, digital camera, PC handwriting pad, electromagnetic oven, micro-wave oven, air-conditioning, refrigerator, refrigerator-freezer, solar water heater, electronic scale, Fingerprint Lock, electronic lock, instrument and meter, sports equipment or the like again, we can say that we are entering touch epoch.Touch-screen is most convenient, simple, input medium intuitively naturally.Along with the modern to the aesthetic conceptions at conserve space and man-machine display interface and the lifting of interactive requirement, will be on the very big aspect sensed formula liquid crystal display key screen of traditional mechanical key and conventional touch screen replaces.Distinguish touch-screen from know-why, 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.Wherein vector pressure sensing technology touch-screen steps down from the stage of history; The infrared technology touch-screen is cheap, but its housing is frangible, is easy to generate light and disturbs distortion under the curved surface situation; It is reasonable that capacitance technology touches design concept, but its pattern distortion problem is difficult to be solved at all, the accurate positioning of capacitance technology touch-screen, but its price is quite high, and be afraid of to scrape rapid wear; Surface acoustic wave touch screen has solved the various defectives of touch-screen in the past, and clear being not easy is damaged, and is suitable for various occasions, has water droplet and dust can make the blunt of touch-screen change if shortcoming is a screen surface, does not even work.According to the principle of work of touch-screen and the medium of transmission information touch-screen is divided into four kinds, they are respectively resistance-type, infrared-type, capacitor induction type and surface acoustic wave type.
Divide from mounting means, touch-screen can be divided into: external hanging type, built-in and monoblock type.The external hanging type touch-screen is exactly the front that the touch detecting apparatus of touch-screen system directly is installed in display device, and this touch-screen simple installation is fit to interim the use very much.Built-in touch-screen is touch detecting apparatus to be installed in the shell of display device the front of display.When making display device, touch screen detection device is produced on the display, make display device directly have touch function, Here it is, and integral touch shields.
Inductive liquid crystal display key screen is the product that LCD combines with the capacitive induction control integrated circuit.It has merged the advantage such as clear and not fragile of accurate positioning, condenser type design rationality, the sound wave type of resistance-type, and mounting means is monoblock type, and is extremely simple and convenient.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, thin thickness, install and fix convenience, long service life, environment-adapting ability is strong, production procedure is simple, cost is low, penetrability is high, dependable performance, man-machine dialog interface is more clear, aesthetics is high inductive liquid crystal display key screen.
For achieving the above object, the invention provides a kind of inductive liquid crystal display key screen, it mainly comprises a single face ito glass, a two-sided ito glass, a glue frame, one first show electrode, one first alignment film, one second show electrode, one second alignment film, a liquid crystal, one first polaroid, an induction electrode ITO layer, one second polaroid.This glue frame is installed between this single face ito glass and this two-sided ito glass.This first show electrode brushing is on the ITO of this single face ito glass conductive layer, and this first polaroid is attached on this single face ito glass another side.This first alignment film printing is on this first show electrode.This second show electrode brushing is on the ITO of this two-sided ito glass conductive layer.This second alignment film printing is on second show electrode.Form the accommodation space of a sealing between this glue frame, first alignment film, second alignment film, this liquid crystal is contained in this accommodation space.Be provided with one group of conductiving point in this glue frame, with this first show electrode of conducting and this second show electrode.This induction electrode ITO layer silk-screen is on another ITO conductive layer of this two-sided ito glass.This second polaroid is attached on this induction electrode ITO layer.
The invention has the advantages that: the technological incorporation of this inductive liquid crystal display key screen the advantage of capacitive touch screen and resistive touch screen, improved their shortcoming.Present technique adopts the ITO layer on the ito glass to make induction electrode.Traditional key screen and LCD are combined as a whole; Do conductive layer (ITO, the tin indium oxide) induction electrode of layer of transparent on the watch crystal substrate with LCD, by induction IC detecting, conversion output corresponding signal is given controller, thereby realizes inducing function.This method has been simplified production technology, has reduced product thickness, improved transmittance and can have been covered any nonconductor protective seam (such as tempered glass, PVC hyaline membrane, organic glass etc.) at the induction screen surfaces, makes it not be vulnerable to scraping and damages.
