摘要: An apparatus may include a one- or two-dimensional array of micromechanical ultrasonic transducer (PMUT) elements positioned below, beside, with, on, above backplane visual display. The be thin-film transistor (TFT) backplane. PMUT piezoelectric capacitive (CMUT) array. configurable to operate in modes corresponding multiple frequency ranges. When operating the low-frequency mode, capable gesture detection. A high-frequency mode fingerprint sensor stylus detection mode.
