TOUCH DETECTION MODULE AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18174523 titled 'TOUCH DETECTION MODULE AND DISPLAY DEVICE INCLUDING THE SAME

Simplified Explanation

The patent application describes a touch detection module that includes driving electrodes, sensing electrodes, and a touch driving circuit.

• The touch detection module has multiple driving electrodes arranged side by side.
• It also has multiple sensing electrodes staggered with respect to the driving electrodes.
• The touch driving circuit supplies touch driving signals to the driving electrodes and detects touch detection signals through the sensing electrodes to identify touch position coordinates.
• The touch driving circuit can vary frequency modulation parameter set values in response to a change in the frequency of reference clocks.
• It generates and supplies a frequency of the touch driving signals using the reference clocks and the varied frequency modulation parameter set value.

Original Abstract Submitted

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.
