    Abstract: The present invention relates to a method of configuring a sensor pattern that linearly detects touch signals based on changes in the active area when a pen touches the ODA that constitutes the object detection device of the present invention installed on the conductive surface. It also pertains to a method of constructing a sensor pattern that minimizes moiré interference with the display device. As a result, the readability of pen-written characters is enhanced, and visibility is improved due to moiré avoidance.

    Abstract: The present invention relates to a novel means and a novel method for detecting a capacitance connected to AC power, which detect a sensor capacitance on the basis of a charge sharing phenomenon occurring due to a difference between voltages applied to a sensor capacitor and an auxiliary capacitor connected to a detection system when an AC voltage applied to the detection system alternates. According to the present invention, since the sensitivity of a signal detected by a detection system is improved, a magnitude and a change amount of a sensor capacitance are stably acquired.

The touch detection device that is added on top of a display device and detects occurrence of a touch capacitance (Ct) by an approach of a bodily finger (25) or a touch input instrument such as a conductor similar to the bodily finger, the touch detection device comprising: a touch pad (10) that forms the touch capacitance (Ct) between the touch input instrument and the touch pad; a driving capacitor (Cdrv) whose one side is connected to the touch pad (10) and to the other side of which a driving voltage for detection of a touch input is applied; a common voltage detector that detects a common voltage generated from the display device; a driving voltage generator that generates the driving voltage in synchronization with the common voltage; and a touch detector that is connected to the touch pad (10), and that detects a touch signal by using a driving back phenomenon when the touch capacitance (Ct) is added to the driving capacitor (Cdrv) according to occurrence or non-occurrence of a touch in the touch input instrument. A touch signal is detected while avoiding a point in time of a change of a common voltage state, and a driving voltage is applied through a driving capacitor connected to a touch detector, to thus detect whether or not a driving back phenomenon occurs in the touch detector and to thereby acquire a touch signal. Accordingly, an influence due to parasitic capacitance generated by noise, coupling phenomenon or other factors is minimized, to thus acquire a touch signal stably.
