Abstract
An acoustic wave surface touch screen with groove form reflective strips is composed of a touch screen, a transducer and reflective strips, which is characterized in that the acoustic wave surface touch screen is provided with groove form reflective strips (2) in which the non-dense strip end is in 90 degree angle with a receiving transducer (3) and a launch transducer and the dense strip end has no transducers. The groove of reflective strips is lower than the touching area, in which the damage of the reflective strips occurred in the transportation and installation processes can be prevented, or the printed reflective strips will not be smeared. Thus the stable performance of the reflective strips can be ensured. The chemical corrosion and the optical laser lithography are adopted for the processing of the grooves.
Description
Technical field
The utility model relates to a kind of computer screen display technique, particularly a kind of groove type reflection strip surface acoustic wave touch screen.
Background technology
Existing surface acoustic wave touch screen, reflection strip all are that projection is being shielded the surface.
Its shortcoming is: it is bigger to process the reflection strip difficulty in the plane.Because make reflection strip on glass display screen firmly, avoid influencing service property (quality) installing, being scratched easily in the use, need to implement the bigger high-sintering process of difficulty, thereby improved manufacturing cost.
Summary of the invention:
The purpose of this utility model is to disclose a kind of reflection strip that can ensure and is not scratched and influences the groove type reflection strip surface acoustic wave touch screen of service property (quality).
The utility model is to adopt following technical scheme to realize above-mentioned purpose:
On the touch-screen glass board material, the place of the printing reflection strip of the surface acoustic wave touch screen of making, be processed into groove with chemical corrosion or optics job operations such as (laser lithographies), the section configuration of groove is respectively rectangle (as shown in Figure 2), trapezoidal (as shown in Figure 3) and arc (as shown in Figure 4).Groove type reflection strip surface acoustic wave touch screen, constitute by touch-screen, transducer, groove type reflection strip, reflection strip 2 on surface acoustic wave touch screen screen body 1 is to be made of to close miter angle virgule by dredging a kind of, reflection strip 2 is dredged end and 4 one-tenth an angle of 90 degrees of receiving transducer 3 and transmitting transducer, and the close end of reflection bar streakline does not have transducer.(as shown in Figure 1)
On the touch-screen glass plate, make the place of surface acoustic wave touch screen reflection strip, adopt chemical corrosion and optics job operations such as (laser lithographies) to be processed into groove and get final product.The reflection strip line groove that is processed into, the section configuration of groove are respectively rectangle (as shown in Figure 2), trapezoidal (as shown in Figure 3) and arc (as shown in Figure 4).
Advantage of the present utility model is:
1, the reflection strip groove is lower than Petting Area, can prevent the damage that reflection strip causes in the installation and transportation process, or prints reflection strip and do not made dirty, thereby has guaranteed the job stability of reflection strip.
2, processing during reflection strip difficulty of processing less, need not high temperature, only need get final product at processing technologys processing reflection strips such as utilization corrosion of the zone of processing reflection strip or laser.
Principle of work of the present utility model:
When the touch-screen body is not touched, received signal is with just the same with reference to waveform, when finger or other write device touch-screen body, finger part energy, a transmitting transducer 4 close with the touch point is the electrical signal conversion that is produced by controller that ultrasound wave sends, and ultrasound wave is propagated to receiving transducer 3 along the direction of arrow among Fig. 1 via the reflection strip 2 of correspondence.After receiving transducer 3 receives, the signal process screen line that absorbs is sent to the controller of touch system, controller carries out analyzing and processing with the signal of receiving again.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is that the utility model groove type reflection strip reaches position view in touch-screen.
Fig. 2 is a rectangular reflection striped groove synoptic diagram.
Fig. 3 is trapezoidal reflection strip groove synoptic diagram.
Fig. 4 is an arc reflection strip groove synoptic diagram.
Wherein: 1, surface acoustic wave touch screen screen body; 2, reflection strip and groove; 3, receiving transducer; 4, transmitting transducer.
Embodiment 1:
On the touch-screen glass plate, make the place of surface acoustic wave touch screen reflection strip, adopt chemical attack And optics (laser lithography) is processed into groove and gets final product. The section configuration of groove is rectangle, and reflection strip is recessed Groove is processed as rectangle, and Pocket Machining processing technologys such as () burn into laser is become by dredging to close reflection strip Line. As shown in Figure 1 and Figure 2.
Embodiment 2:
On the touch-screen glass plate, make the place of surface acoustic wave touch screen reflection strip, adopt chemical corrosion and optics (laser lithography) to be processed into groove and get final product.The section configuration of groove is trapezoidal, the reflection strip groove is processed as trapezoidal, and groove processing processing technologys such as () burn into laser is become by dredging to close reflection bar streakline.As Fig. 1, shown in Figure 3.
Embodiment 3:
On the touch-screen glass plate, make the place of surface acoustic wave touch screen reflection strip, adopt chemical corrosion and optics (laser lithography) to be processed into groove and get final product.The section configuration of groove is an arc, and the reflection strip groove is processed as arc, and groove processing processing technologys such as () burn into laser is become by dredging to close reflection bar streakline.As Fig. 1, shown in Figure 4.
Claims (2)
