阅读说明：本技术 指纹识别模组及其驱动方法和电子装置 (Fingerprint identification module, driving method thereof and electronic device ) 是由 刘英明 丁小梁 李秀锋 王鹏鹏 于 2020-01-17 设计创作，主要内容包括：一种指纹识别模组及其驱动方法和电子装置。该指纹识别模组包括接收电极层、压电材料层、第一驱动电极层和第二驱动电极层。接收电极层包括多个接收电极；压电材料层设置在接收电极层的一侧；第一驱动电极层设置在压电材料层远离接收电极层的一侧且包括多个第一驱动电极；第二驱动电极层设置在接收电极层远离压电材料层的一侧且包括多个第二驱动电极,多个第一驱动电极和多个第二驱动电极形成多个驱动电极对,各驱动电极对中的第一驱动电极和第二驱动电极在压电材料层上的正投影至少部分重叠。由此,该指纹识别模组可实现以较低的驱动电压实现对压电材料层的高压驱动或高压激励。(A fingerprint identification module, a driving method thereof and an electronic device are provided. The fingerprint identification module comprises a receiving electrode layer, a piezoelectric material layer, a first driving electrode layer and a second driving electrode layer. The receiving electrode layer comprises a plurality of receiving electrodes; the piezoelectric material layer is arranged on one side of the receiving electrode layer; the first driving electrode layer is arranged on one side, far away from the receiving electrode layer, of the piezoelectric material layer and comprises a plurality of first driving electrodes; the second driving electrode layer is arranged on one side, far away from the piezoelectric material layer, of the receiving electrode layer and comprises a plurality of second driving electrodes, the plurality of first driving electrodes and the plurality of second driving electrodes form a plurality of driving electrode pairs, and orthographic projections of the first driving electrodes and the second driving electrodes in the driving electrode pairs on the piezoelectric material layer at least partially overlap. Therefore, the fingerprint identification module can realize high-voltage driving or high-voltage excitation on the piezoelectric material layer by using lower driving voltage.)
