Description
Technical field
The utility model belongs to touch screen technology field (G06F 3/044), is specifically related to a kind of intelligent touch-screen.
Background technology
Touch-screen is also called " touch screen ", " contact panel ", it is a kind of induction type liquid crystal indicator receiving the input signals such as contact, when contacting the graphic button on screen, haptic feedback system on screen can drive various hookup mechanism according to the formula of programming in advance, in order to replace mechanical push button panel, and lively visual and sound effects can be produced by liquid crystal display picture.Touch-screen is a kind of up-to-date computer input apparatus, and it is the simplest, convenient current, natural a kind of man-machine interaction mode.It giving the looks that multimedia is brand-new, is extremely attractive brand-new multimedia interactive equipment.Be mainly used in the inquiry of public information, leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, real estate presell etc.
Capacitance-type touch screen technology utilizes the electric current of human body to respond to carry out work.Capacitive touch screen is one piece of four layers of compound glass screen; the inside surface of glass screen and interlayer respectively scribble one deck ITO, and outermost layer is skim silicon soil glassivation, and interlayer ITO coating is as workplace; four electrodes are drawn at four angles, and internal layer ITO is that screen layer is to ensure good working environment.
When finger touch on the metal layer time, due to human body electric field, user and touch screen surface form a coupling capacitance, and for high-frequency current, electric capacity is direct conductor, so finger siphons away a very little electric current from contact point.This electric current flows out respectively from the electrode the corner of touch-screen, and the electric current flowing through these four electrodes is directly proportional to the distance of finger to corner, and controller, by the accurate Calculation to these four current ratios, draws the position of touch point.
Capacitance plate mainly contains self-capacitance screen and mutual capacitance screen two kinds, more common mutual capacitance screen is example, inside is made up of drive electrode and receiving electrode, drive electrode sends low-voltage high-frequency signal and projects receiving electrode and form stable electric current, when human contact is to capacitance plate, due to human body grounding, finger just forms an equivalent capacity with capacitance plate, and high-frequency signal can flow into ground wire by this equivalent capacity, like this, the quantity of electric charge that receiving end receives reduces, and when pointing the closer to transmitting terminal, electric charge reduces more obvious, the strength of current finally received according to receiving end determines touched point.
First characteristic of touch-screen: transparent, it directly has influence on the visual effect of touch-screen.Transparent have transparent degree problem, infrared technology touch-screen and surface acoustic wave touch screen are all only every the pure glass of one deck, transparent outstanding person at last, this point of other touch-screen will weigh some carefully, " transparent " is in touch-screen industry, just individual concept very general, a lot of touch-screen is the laminated film of multilayer, only inadequate by the more transparent visual effect summarizing it, it at least should comprise four characteristics: transparency, color distortion degree, reflective and sharpness, can also divide again, such as reflective degree comprises the reflective degree of minute surface and the reflective degree of diffraction, the only reflective degree also not arriving CD dish of touch screen surface diffraction, for user, these four tolerance are substantially much of that.
Due to the existence of light transmission and wavelength curve figure, the image seen by touch-screen inevitably and original image create color distortion, static image sensation is also the distortion of color, dynamic multi-media image sensation is not just very comfortable, and the maximum colours degree of distortion in color distortion degree i.e. figure is the smaller the better naturally.Usual said transparency also can only be the average transparency in figure, and it is more high better that yes.
Reflective, mainly refers to because mirror-reflection causes shadow on image after overlap, as the shadow, window, light etc.Reflective is the counter productive of touch-screen, and the smaller the better, it affects the surfing of user, is even beyond recognition image character time serious, and the environment for use of the touch-screen that reflective is strong is restricted, and on-the-spot lamplight setting is also forced to need adjustment.The touch-screen that great majority exist reflective problem all provides another surface treated frosting touch-screen, and be also anti-dazzle type touch-screen, price is slightly higher, anti-dazzle type reflective obviously declines, be applicable to the very sufficient hall of daylighting or exhibition place, but, the light transmission of anti-dazzle type and sharpness also have decline by a relatively large margin thereupon, after some touch-screen installs additional, the handwriting is blurred, and image detail is fuzzy, and whole screen seems unintelligible, see not clear, sharpness that Here it is is too poor.The touch-screen of the problem of sharpness mainly multi-layer film structure, because between thin layer, the refraction of light interreflection causes.In addition anti-dazzle type touch-screen also causes sharpness to decline due to surface frosted, and sharpness is bad, and eyes are easily tired, also has certain injury to eyes, will note differentiating when choosing touch-screen.
Second characteristic of touch-screen: touch-screen is absolute coordinate system, which position be selected just directly to put that position, is the intuitive of one-time-reach-place with the essential distinction of this kind of Relative positioning systems of mouse.The feature of absolute coordinate system be each time the elements of a fix and the last elements of a fix it doesn't matter, touch-screen is a set of independently coordinate positioning physically, the data of each touch transfer the coordinate on screen to by calibration data, like this, no matter when just require this cover coordinate of touch-screen, the output data of same point are stable, if unstable, touch-screen just can not ensure that absolute coordinates is located.Touch-screen location is inaccurate, and this is the problem that people worry touch-screen most.
3rd characteristic of touch-screen: detect and touch and locate, various touch screen technology is all that the respective sensor of dependence carrys out work, and respective positioning principle and sensor used separately determine the reaction velocity of touch-screen, reliability, stability and life-span.
The general all structures of existing touch-screen are simple, and itself is sensor installation not, by the cooperation of other parts of main frame, must could realize certain function, reduce the sensitivity of touch-screen, occur delayed problem when causing touch-screen to feed back touch information.As long as any fault occurs main frame, all have a strong impact on the duty of touch-screen, add the input of cost, occupy larger space, increase the energy consumption of main frame, be unfavorable for the saving of the energy.
