Application: Ultrasonic image sensor and related electronic device (Patent ID: US20230397902A1)

The patent application from Shenzhen Goodix Technology Co Ltd describes an ultrasonic image sensor coupled to a sinusoidal pulse signal generating circuit, located below a cover plate. The sensor is designed to detect surface patterns of objects in contact with the cover plate by generating ultrasonic waves through a piezoelectric layer excited by the signal. The reflected echo is then received and processed by a detection circuit array, providing accurate measurements.

The ultrasonic image sensor includes various components such as upper and lower electrodes, a piezoelectric layer, and a detection circuit array. The detection process involves specific phases based on the pulse period of the sinusoidal signal, with the first detection circuit determining the amplitude of the receiving signal. Additionally, the sensor features a control circuit for signal and switch control, as well as calibration elements to offset static noise. This technology can be integrated into electronic devices with display screens, allowing for non-invasive and precise object detection capabilities.
