Touch sensor driving device and display device comprising the same

摘要

A touch sensor driving device comprises: a plurality of touch sensing circuits that receive touch sensor sensing signals from touch sensors of a touchscreen through a plurality of receiving channels; and a plurality of discharge circuits connected between the receiving channels and the touch sensing circuits to receive charge eliminating pulse signals and reduce the swing amplitude of the touch sensor sensing signals input into the touch sensing circuits.
