DERMATOGLYPHICS DATA ACQUISITION DEVICE, ACQUISITION METHOD THEREOF AND DISPLAY DEVICE
First Claim
1. A dermatoglyphics data acquisition device, comprising:
- a capacitive touch control circuit, configured to detect a touch region of a dermatoglyphics on a touch device;
a controller, configured to select a touch center region in the touch region and select a characteristic region in the touch center region, according to a signal amount distribution of a touch signal generated by dermatoglyphics contact in the touch region, and determine the characteristic region as a dermatoglyphics scan region; and
a dermatoglyphics identification circuit, configured to scan a dermatoglyphics in the dermatoglyphics scan region and generate a dermatoglyphics data.
