TOUCH INPUT SENSING APPARATUS AND TOUCHSCREEN APPARATUS INCLUDING THE SAME

摘要

According to an embodiment of the present invention, a touch sensing apparatus comprises: a driving signal generating circuit for applying a driving signal to a first node of a node capacitor; and a buffer circuit for comprising at least one switch connected to a second node of the node capacitor, and generating output voltage by integrating voltage of the second node of the node capacitor. The second node of the node capacitor can be floated at least one time during a period of the driving signal according to a switching operation of at least one switch connected to the second node of the node capacitor.
