    • According to one embodiment, a display device includes a plurality of pixel circuits which are arranged in a matrix, a plurality of sensor circuits which are arranged in regions between the pixel circuits and which read the magnitude of capacitance coupling, a plurality of scanning lines for the pixel circuits and sensor circuits, a plurality of signal lines for the pixel circuits and sensor circuits a part of which are shared, a controller which controls alternating-current driving that inverts, with a specific period, the polarity of a display signal written into the pixel circuits, and a determination module which determines a magnitude correlation between a sensor signal read from the sensor circuit and a polarity-based threshold value corresponding to the polarity of alternating-current driving in reading the sensor signal.
    • 根据一个实施例,显示装置包括排列成矩阵的多个像素电路,布置在像素电路之间并且读取电容耦合幅度的多个传感器电路中的多条扫描线, 像素电路和传感器电路,用于像素电路和传感器电路的一部分共享的多条信号线,控制交流电驱动的控制器,该控制器以特定的周期将写入的显示信号的极性反转 像素电路和确定模块,其确定从传感器电路读取的传感器信号与在读取传感器信号时对应于交流驱动极性的基于极性的阈值之间的大小相关性。
