Abstract

The invention discloses a double-touch-face surface acoustic wave touch screen, which comprises a substrate, a transmitting stripe array, a receiving stripe array, a receiving transducer and a transmitting transducer. The substrate surface includes a first touch face, a second touch face and a transmission face; the transmitting stripe array, the receiving stripe array, the receiving transducer and the transmitting transducer are all arranged on the same touch face; the first and second touch faces are arranged opposite to each other; and the transmission face is connected with the first and second touch faces respectively. The invention involves two touch faces for normal touch, one touch face is provided with an assembly, the other touch face is provided with no functional part, no complex front frame assembly is required to be designed for shielding stripe arrays, transducers and the like, and the touch face without any functional part can directly serve as the front panel of a touch display product, so as to realize acoustic wave touch screen frame-free design.

Description

technical field

[0001] The invention relates to a novel surface acoustic wave touch screen, in particular to a novel surface acoustic wave touch screen with double touch surfaces. Background technique

[0002] In the prior art, touch screens mainly include surface acoustic wave, infrared, resistance, capacitance and the like. The surface acoustic wave touch screen has the characteristics of high resolution, short response time, good stability, good anti-riot performance, and high transmittance; the infrared touch screen has general resolution, long response time, general stability, good anti-riot performance, and high transmittance. It is easy to be interfered by light; the resistive touch screen has the characteristics of high resolution, short response time, good stability, poor transmittance, and poor anti-riot performance; the capacitive touch screen has high resolution, short response time, general stability, and transparency. It has the characteristics of general over...
