  • Publication number: 20150123940
    Abstract: A touch sensing system and a method for driving the same. The touch sensing system includes a pen with a resonant circuit embedded therein, XY electrodes including X electrodes and Y electrodes substantially perpendicular to the X electrodes, an antenna surrounding the XY electrodes, and a first touch driving circuit. The first touch driving circuit supplies a resonant inductive signal to the XY electrodes, analyzes a resonance signal received through the antenna, and decides a location and a pen pressure of the pen. The resonant inductive signal includes N periods each having a different duration, and wherein N is a positive integer equal to or greater than 2.

  • Publication number: 20150091856
    Abstract: A touch sensing system includes a pen including at least one resonant circuit embedded therein, XY electrodes including X electrodes and Y electrodes perpendicular to the X electrodes, an antenna surrounding the XY electrodes, and a first touch driving circuit which supplies a resonant inductive signal to the XY electrodes, decides a location of the pen based on a resonance magnitude of a resonance signal received through the antenna, and decides a pen pressure of the pen based on a resonant frequency of the resonant circuit and an adjacent frequency of the resonant frequency measured while varying a frequency of the resonant inductive signal.

  • Publication number: 20150084899
    Abstract: A touch sensing system includes a pen including a resonant circuit embedded therein, XY electrodes including X electrodes and Y electrodes perpendicular to the X electrodes, an antenna surrounding the XY electrodes, and a first touch driving circuit which transmits a resonant inductive signal to the pen through electric coupling and to receive a resonance signal from the pen through the antenna.
