摘要： A surface acoustic wave touch panel and a system of the same are provided. The system includes the touch panel, an input/output (I/O) controlling unit, a detecting unit, and a signal processing unit. The touch panel includes a substrate on which at least one first emitter and at least one second emitter are provided on two adjacent edges thereof, and at least one first receiver and at least one second receiver are provided on the other two adjacent edges of the substrate. The I/O controlling unit controls the emitters to emit signals, and controls the detecting unit to pick up output signals from the receivers. The signal processing unit uses a neural network to determine an amplitude-reduction feature of any of the output signals so as to identify a position being touched on the touch panel. The touch panel is provided with high resolution and high throughput.
