Abstract:
A touch detection module, includes: a plurality of driving electrodes arranged side by side; a plurality of sensing electrodes staggered with respect to the driving electrodes; and a touch driving circuit configured to supply touch driving signals to the plurality of driving electrodes and to detect touch detection signals through the plurality of sensing electrodes to identify touch position coordinates, wherein the touch driving circuit is configured: to vary frequency modulation parameter set values in response to a change in a frequency of reference clocks, and to generate and supply a frequency of the touch driving signals by using the reference clocks and a varied frequency modulation parameter set value.
