Title:
DRIVING CONTROL CIRCUIT AND DRIVING METHOD THEREFOR, AND HAPTIC FEEDBACK APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/031415
Kind Code:
A1
Abstract:
A driving control circuit (200), comprising a feedback detection circuit (210), a data processing circuit (220), and a feedback driving circuit (230). The feedback detection circuit (210) is configured to, when a target object is pressed, process an initial voltage signal of each of at least one haptic detection piezoelectric device (021), and then output a detection signal corresponding to each of the at least one haptic detection piezoelectric device (021); the data processing circuit (220) is configured to receive the detection signal corresponding to each of the at least one haptic detection piezoelectric device (021), and output a driving enable signal according to the detection signal corresponding to each of the at least one haptic detection piezoelectric device (021) and a set threshold; and the feedback driving circuit (230) is configured to receive the driving enable signal, and output a driving control signal to at least one haptic driving piezoelectric device (022) according to the driving enable signal.
