摘要： Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal. The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.
摘要翻译： 这里描述了多触摸触摸感测装置和方法。 触摸感测装置可以包括多个感测点，每个感测点位于驱动线和感测线的交叉处。 在一些实施例中，多个驱动线可以同时或几乎同时受到具有独特特征的驱动信号（例如相位或频率）的刺激。 感测信号可以在可以与驱动信号相关联的每个感测线上发生存在于对应于被刺激的驱动线和感测线的感测点处的触摸量。 通过使用基于唯一驱动信号的处理技术，可以从感测信号中提取对应于每个感测点的触摸量。 触摸感测方法和装置可以并入用于各种电子设备的接口，例如台式机，平板电脑，笔记本电脑和手持式计算机，个人数字助理，媒体播放器和移动电话。
