Method and device for position detection |
摘要 |
The present invention provides a method and device for position detection. For detection of a touch position, a segment of surface acoustic wave (SAW) is provided multiple times to be propagated on a SAW touch panel, and the multiple SAW segments are received by the SAW touch panel. In addition, during or after reception, partial output electrical signals are provided based on different portions of each received SAW segment to construct a complete output electrical signal. |

1. A position detecting method, comprising:
providing a surface acoustic wave (SAW) touch panel; providing multiple SAW segments to be propagated on the SAW touch panel; receiving the SAWs propagated on the SAW touch panel; and providing a segment of partial output electrical signal based on a different portion of each received SAW and combining all of the partial output electrical signals to form a complete output electrical signal, wherein each segment of partial output electrical signal is generated based on a gain, a second gain of a latter partial output electrical signal being larger than a first gain of a front partial output electrical signal. |
