发明名称
可重送驱动信号之并行驱动电容式触控感测装置;CONCURRENT DRIVING CAPACITIVE TOUCH SENSING DEVICE CAPABLE OF RESENDING DRIVE SIGNALS
摘要
一种并行驱动电容式触控感测装置,包含一驱动端、一电容感测阵列以及一侦测端。该电容感测阵列具有互相交错的复数驱动电极及复数侦测电极。该驱动端用以同时对该等驱动电极输入编码及调变后驱动信号之周期数据。该侦测端耦接该等侦测电极其中之一并相对该被耦接的侦测电极相关之该周期数据撷取一预设数目之取样值,并根据该等取样值产生一回应讯息至该驱动端,其中,该驱动端根据该回应讯息重送该周期数据。
