| titleOfInvention | Coordinate detection device and coordinate detection method |
| abstract | The present invention provides a coordinate detection method for accurately detecting touch coordinates without using a special pen on a substrate such as a touch panel. The method includes: obtaining STA (Short Time Average) for output signals of at least three vibration detectors separated by a predetermined distance on a substrate of a certain thickness made of a homogeneous material with a constant propagation speed of vibration waves The step of ratio with LTA (Long Time Average); the step of obtaining the time when the STA/LTA ratio of the three vibration detectors exceeds a predetermined threshold using the vibration wave generated by touching the substrate as the time of arrival; and, according to each The steps of obtaining the touch position coordinates based on the arrival time, the propagation speed of the vibration wave, and the separation distance between the installation positions of the three vibration detectors. |
