Sensing and driving apparatus, touch sensing system, and sensing and driving method

摘要

A sensing and driving apparatus suitable for a sensing interface is provided. The sensing and driving apparatus includes a driving module and a sensing unit. The driving module outputs a first reference signal and a second reference signal which have different polarities with each other, and respectively transmits the first reference signal and the second reference signal to a first driving line and a second driving line of the sensing interface so as to generate a first sensing signal during a first period. The sensing unit receives the first sensing signal and detects a change of the first signal so as to generate a sensing result. A sensing and driving method, a touch sensing system and a device using the same are also provided herein.

1. A sensing and driving apparatus suitable for a sensing interface, the sensing and driving apparatus comprising:
a driving module, outputting a first reference signal and a second reference signal which have different polarities with each other, and respectively transmitting the first reference signal and the second reference signal to a first driving line and a second driving line of the sensing interface so as to accordingly generate a first sensing signal during a first period, wherein the first driving line and the second driving line are extended along the same direction of the sensing interface; and a sensing unit, receiving the first sensing signal and detecting a change of the first sensing signal so as to generate a sensing result accordingly, wherein the first driving line receiving the first reference signal and the second driving line receiving the second reference signal are two adjacent driving lines of the sensing interface extended along the same direction of the sensing interface.
