摘要： The present invention relates to a method and apparatus for generating driver signals of SAW touch panel. The method includes the steps of: sending a trigger signal continuously by referring to an input signal, wherein the trigger signal is sent when the input signal is within a predetermined range; generating a surface acoustic wave according to the trigger signal; transmitting the surface acoustic wave to at least one transducer via a touch surface; and detecting the input signal via at least one transducer. Moreover, the input signal is kept on a predetermined level when the surface acoustic wave has not been received by the transducer and when a noise signal from circuits outside the transducer has not been added in the input signal. The predetermined level is within the predetermined range. The sensing accuracy of the SAW touch panel can be enhanced because the noise signal has less effect on the driver signals.
摘要翻译：本发明涉及一种用于产生SAW触摸面板的驱动器信号的方法和装置。该方法包括以下步骤：通过参考输入信号连续发送触发信号，其中当输入信号在预定范围内时发送触发信号; 根据触发信号产生声表面波; 经由触摸表面将表面声波传播到至少一个换能器; 以及经由至少一个换能器检测输入信号。此外，当声表面波没有被换能器接收并且当来自换能器外部的电路的噪声信号未被添加到输入信号中时，输入信号保持在预定水平。预定水平在预定范围内。由于噪声信号对驱动器信号的影响较小，因此能够提高SAW触摸面板的检测精度。
