  • Two-level coding/decoding-based touch sensing device and touch sensing method for mutual capacitance touch sensor
    Patent number: 11662857
    Abstract: The embodiment applies a two-level coding/decoding technology using a spread spectrum code and an orthogonal code, whereby touch sensing can be robust against noise, a touch sensing time can be reduced, and touch sensitivity can be enhanced.
    Type: Grant
    Filed: December 8, 2021
    Date of Patent: May 30, 2023
    Assignee: LX SEMICON CO., LTD.

  • Touch sensing method and touch sensing device
    Patent number: 11586324
    Abstract: The present disclosure relates to a technology for assigning group labels during touch sensing, and more particularly to a technology for preventing two adjacent objects from receiving a same group label by searching for a valley when group labels are assigned and this allows labeling without performing any object separation process.
