    • A capacitance-type fingerprint sensor. The capacitance-type fingerprint sensor includes a plurality of pixel groups, each of which electrically connects a plurality of sensing electrodes to a plurality of coupling electrodes, respectively; a plurality of first sensing-electrode switches for connecting the sensing electrodes to a voltage source; a plurality of second sensing-electrode switches for interconnecting the sensing electrodes contained in the pixel groups; a plurality of third sensing-electrode switches for interconnecting the pixel groups; and a plurality of coupling-electrode switches for interconnecting the coupling electrodes contained in all pixel groups. Therefore, the fingerprint sensor blocks or corrects capacitance generated by internal components of a fingerprint sensor, such that it acquires a high-quality fingerprint image. Also, the fingerprint sensor corrects or reduces the influence of the dry or moist state of a finger surface, such that a fingerprint image can be more uniformly indicated.
    • 电容式指纹传感器。 电容型指纹传感器包括多个像素组,每个像素组分别将多个感测电极电连接到多个耦合电极; 用于将感测电极连接到电压源的多个第一感测电极开关; 多个第二感测电极开关,用于互连包含在像素组中的感测电极; 多个用于互连像素组的第三感测电极开关; 以及用于互连所有像素组中包含的耦合电极的多个耦合电极开关。 因此,指纹传感器阻挡或校正由指纹传感器的内部部件产生的电容,从而获得高质量的指纹图像。 此外,指纹传感器校正或减少手指表面的干燥或潮湿状态的影响,使得可以更均匀地指示指纹图像。

    • A depth sensing apparatus is provided. The depth sensing apparatus may reset, to a reference voltage value, a voltage of each of a first floating diffusion node and a second floating diffusion node of a sensor pixel for a first time period. For a second time period, the depth sensing apparatus may control the first floating diffusion node to store a voltage of a photodiode in a first phase interval, and may control the second floating diffusion node to store the voltage of the photodiode in a second phase interval. The depth sensing apparatus may calculate a difference between the voltage of the first floating diffusion node and the voltage of the second floating diffusion node for a third time period.
    • 提供深度感测装置。 深度感测装置可以将第一时间段内的传感器像素的第一浮动扩散节点和第二浮动扩散节点中的每一个的电压重置为参考电压值。 对于第二时间段,深度感测装置可以控制第一浮动扩散节点以在第一相间隔中存储光电二极管的电压,并且可以控制第二浮动扩散节点将光电二极管的电压存储在第二相位间隔 。 深度感测装置可以计算第三浮动扩散节点的电压与第二浮动扩散节点的电压之间的差值。
