Application: Detection device (Patent ID: US20240071128A1)

The patent filed by Japan Display Inc. describes a detection device that includes multiple optical sensors arranged in a detection area, a light source emitting light to be detected by the sensors, and a processor for processing sensor outputs. The processor determines which sensor output to use based on outputs obtained at regular intervals.

The device divides the detection area into group areas, with each group area containing sensors in partial detection areas. The processor selects the sensor output to use based on the group area with the highest output during a predetermined period. Additionally, the device can operate all sensors at regular intervals and selectively operate sensors based on previous outputs. The sensors can be arranged in a matrix configuration, and the processor can perform averaging processing to determine which sensor output to employ. The device can be used for fingerprint recognition, vascular pattern detection, and pulse wave detection, with a light source emitting blue, green, or infrared light for detection purposes.
