Abstract
The utility model relates to a surface sound wave touch screen which does not increase the thickness. The utility model is composed of a touch screen and an inductor. The utility model is characterized in that a bevel angle is made by the three angles of the glass touch screen 1, and a transducer 4 is arranged on the bevel angle. The angle legs of the three angles of the glass touch screen 1 are taken out, then the transducer 4 is arranged on the edge of the angle leg. The transducer 4 is arranged on the edges of the three angles of the glass touch screen 1.
Description
The utility model relates to a kind of computer screen display technique, particularly a kind of surface acoustic wave touch screen that does not increase thickness.
Touch screen technology also is in developing stage, 8.4 in the world at present, and " following is controlled 8.4, and " above is controlled by the American by the Japanese.In China, 8.4 " above surface acoustic wave touch screen technology only has a company to grasp the large-scale production technology in Sichuan.Touch screen technology is used very extensive, as: the inquiry of public information: as the service inquiry of departments such as telecommunications, the tax, bank, insurance, electric power, the data check in the flight at airport, station, train query, museum, the Art Museum, library; Be applied to public telephone equipment for surfing the net, network POS terminal, leader's office, Industry Control, military commanding, electronic game, choosing song or selecting dish, multimedia teaching, real estate sale or the like in addition.
Existing touch-screen, screen the body upper left corner and the lower right corner have been fixed one respectively vertically and the ultrasound transmitting transducer of horizontal direction, and two corresponding ultrasound wave receiving transducers have then been fixed in the upper right corner.Four peripheries of screen body then are carved with miter angle by dredging the very reflection strip 2 of precision of close spacing.With the Y-axis is example, and transmitting transducer YS is the electrical signal conversion that is produced by controller that ultrasonic energy sends.Transducer designs makes it have narrower deflection and propagates acoustic surface wave energy left, in the transmittance process, upwards be reflected into the even face propagation of the perpendicular direction of screen surface again by base 45 degree reflection strips 2, gathered into line to the right by the reflection strip 2 of top again then and be transmitted to Y-axis receiving transducer YS, and finally transfer electric signal to and reclaim to controller.
When not touching, the waveform of received signal is with just the same with reference to waveform.When the finger touch screen, finger a part of acoustic wave energy, controller then detects received signal in the decay at certain a moment, can calculate the position of touch point on Y-axis thus, same principle can obtain the position of the X-axis of touch point, as shown in Figure 1.The X that can respond except general touch-screen, the Y coordinate, surface acoustic wave touch screen also responds its 3rd exclusive Z axial coordinate, just can perception user touch pressure sizes values.Its principle is that the damping capacity by the receiving signal attenuation place calculates.Three in case determine that controller is just passed to main frame to them.Because surface acoustic wave is highly stable, and the controller of surface acoustic wave touch screen comes calculated touch location by measuring the position of attenuation initiation on time shaft, so surface acoustic wave touch screen is highly stable, precision is also very high.
But, no matter be domestic or external, all be on the surface at four transducers with the X-axis Y-axis 3 angles being installed in the screen body, shown in the position of XS4, XF4, YS4 and YF4 among Fig. 1, its shortcoming is: 1, when screen body front has enclosing cover to cooperate, transducer is easily damaged, and is unfavorable for final assembly; 2, because transducer is installed on the screen surface, increased the thickness of screen body, can not satisfy has the complete machine of requirement to use to the touch-screen gauge.
The purpose of this utility model is to disclose a kind of touch-screen size and thickness of not increasing, also the surface acoustic wave touch screen that does not increase thickness of fragile transducer not.
The technical scheme that the utility model adopted is:
Three angles of the surface acoustic wave touch screen 1 that glass material is made are made into the angle of chamfer, shown in Fig. 2 and Fig. 3 A, transducer 4 are installed on the inclined-plane, angle.
The corner is removed at three angles of the surface acoustic wave touch screen 1 that glass material is made, and shown in Fig. 3 B, transducer 4 is installed on the corner.
Advantage of the present utility model is:
Because the installation site of transducer is on the angle of chamfer, on the corner and the edge, except the third a little, all the other two kinds do not increase touch-screen thickness and length and width size.Cooperate for installation and complete machine and bring great convenience.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is existing surface acoustic wave touch screen transducer position synoptic diagram.
Fig. 2 is the utility model transducer position synoptic diagram
Fig. 3 is the utility model transducer A, B, C3 kind position view
Wherein: 1, surface acoustic wave touch screen; 2, surface acoustic wave reflection clause; 3, cable; 4, transducer; XF, X-axis transmitting transducer; XS, X-axis receiving transducer; YF, Y-axis transmitting transducer; YS, Y-axis receiving transducer; FS, emission receiving transducer plug.
Embodiment
Adopt the glass cold machining process with glass material touch-screen 1 chamfer grinding, three angles are made into the angle of chamfer, transducer 4 are installed on the angle of chamfer, shown in Fig. 2 and Fig. 3 A.
Adopt the glass cold machining process that the corner is removed at three angles of glass material touch-screen 1, transducer 4 is installed on the corner, shown in Fig. 3 B
According to the installation site, needing the position of processing polishing is the both sides at angle, the upper right corner, the one side by the upper right corner at the lower right corner and angle, the upper left corner.Or touch-screen any one jiao for processing polishing be the angle on both sides, two angles closing on are processing polishing one side just.Process the diagonal angle of two corners, and the one side at two angles closing on by the diagonal angle can not process.
