  • Patent number: 11476402
    Abstract: The present invention relates to a pressure signal detection circuit and a pressure signal detection method in which a pyroelectric signal from a piezoelectric film is suppressed. More specifically, the pressure signal detection circuit receives input of an input signal from a piezoelectric film, differentiates the input signal for signal component analysis of the input signal, outputs the signal analysis value of the input signal based on the differential value, removes offset of the input signal by using the signal component analysis value, integrates the input signal, and outputs a pressure input signal value from which a heat input signal value is removed.

  • Patent number: 10768757
    Abstract: A flexible touch screen panel includes a thin film substrate divided into an active area and a non active area positioned at the outside of the active area; sensing patterns formed on the active area of a first surface of the thin film substrate, including first sensing cells formed to be connected along a first direction and second sensing cells formed to be connected along a second direction; and sensing lines formed on the non active area of the first surface of the thin film substrate. The sensing lines are connected to the sensing patterns. In the touch screen panel, the area and/or interval of the sensing cells formed on a first region, which is capable of being bent by predetermined curvature about a folding axis is different from the area and/or interval of the sensing cells formed on a second region as a flat region except the first region.
