Problems solved by technology

However, the existing technologies represented by the above two patent documents either realize multi-touch by adding transducers and corresponding circuits, or realize multi-touch by adding an independent Z-axis positioning device. Although real touch response of two or more points can be realized, due to the increase of components, not only the cost of the surface acoustic wave touch screen is higher, but also the weight and thickness of the acoustic wave touch screen are heavier, which is different from the current market demand. , Narrow, borderless and flat touch screens run counter to each other

Abstract

The invention discloses a reflection fringe array for a multi-point surface acoustic wave touch screen. The reflection fringe array comprises a plurality of parallel reflecting units. Each reflecting unit comprises a plurality of reflecting fringes. The reflection fringe array has the advantages that one acoustic wave signal can be reflected into a plurality of acoustic wave signals of different directions, and multi-point actual touch response of at least two points can be achieved under the premise that equipment or device is not increased.

Description

technical field [0001] The invention relates to a surface acoustic wave touch screen, in particular to a reflective stripe array for a multi-point surface acoustic wave touch screen. Background technique [0002] The current touch screens mainly include surface acoustic wave, infrared, and capacitive types. Among them, the surface acoustic wave touch screen has become the most popular among several mainstream touch screens due to its advantages such as high resolution, short response time, strong environmental adaptability, good stability, and good light transmission. A touch screen with promotional value. [0003] The existing ordinary surface acoustic wave touch screen has only two physical positioning axes, X axis and Y axis, which are perpendicular to each other. Based on the principle of axis intersection, a touch point can be accurately identified and a unique set of position coordinate data can be obtained. The specific principle is: the X axis For example, the contr...
