    • A touch sensor configured to be disposed in a liquid crystal display panel includes a plurality of x-axis read-out lines crossing and insulated from a plurality of y-axis read-out lines and a plurality of sensor units. Each sensor unit includes a reset unit, a capacitance detector, a first output unit, and a second output unit. The reset unit outputs a first reset signal based on a first control signal. The capacitance detector changes the first reset signal based on a variation of a cell gap of the liquid crystal display panel caused by a touch event. The first output unit changes an electric potential of a corresponding x-axis read-out line in response to the first reset signal changed in the capacitance detector. The second output unit changes an electric potential of a corresponding y-axis read-out line in response to the first reset signal changed in the capacitance detector.
    • 配置为设置在液晶显示面板中的触摸传感器包括与多个y轴读出线和多个传感器单元交叉并绝缘的多个x轴读出线。 每个传感器单元包括复位单元,电容检测器,第一输出单元和第二输出单元。 复位单元基于第一控制信号输出第一复位信号。 电容检测器基于由触摸事件引起的液晶显示面板的单元间隙的变化而改变第一复位信号。 响应于在电容检测器中改变的第一复位信号,第一输出单元改变对应的x轴读出线的电位。 响应于在电容检测器中改变的第一复位信号,第二输出单元改变对应的y轴读出线的电位。
