Ultrasound fingerprint sensor techniques and methods for multi-faceted displays

Devices, systems, and methods are provided for ultrasonic fingerprint sensors featuring an ultrasonic transmitter and a plurality of subsets of ultrasonic sensor pixels, each associated with a different ultrasonic sensitive display surface, where at least two ultrasonic sensitive display surfaces are non-coplanar with each other. In some implementations, ultrasound sensitive display surfaces may be provided by different portions of a flexible display that has been bent into a configuration in which two or more portions thereof are non-coplanar. In some examples, a controller may be provided that selectively reads ultrasonic sensor signals from a subset of ultrasonic sensor pixel (s) associated with an ultrasonic sensitive display surface that a touch sensing system indicates that a touch event is experiencing. 提供了用于超声指纹传感器的装置、系统和方法，这些超声指纹传感器以超声发射器和多个超声传感器像素子集为特色，每个超声传感器像素子集与不同的超声敏感显示表面相关联，其中至少两个超声敏感显示表面彼此非共面。在一些实现中，诸超声敏感显示表面可由柔性显示器的不同部分提供，该柔性显示器已被弯曲成其两个或更多个部分非共面的配置。在一些实例中，可以提供控制器，该控制器从与触摸感测系统指示正在经历触摸事件的超声敏感显示
