The invention discloses a palm feature recognition device and a recognition method. The recognition device comprises a finger area which is located in a first portion of a display screen and comprisesa plurality of identical finger touch electrodes which detect a fingerprint signal when a palm presses the finger area, a palm area which is located in a second portion of the display screen and comprises a plurality of identical palm touch electrodes which detect a palm print signal when the palm presses the palm area, a first control chip which is connected to the finger area and obtains fingerprint data according to the fingerprint signal, a second control chip which is connected to the palm area and obtains palm print data according to the palm print signal, a processor which is connectedto the first control chip and the second control chip and compares the fingerprint data and the palm print data with the feature data for identity verification, wherein each of the finger touch electrodes is smaller than each of the palm touch electrodes. According to the palm feature recognition device of the invention, the principle of electrode segmentation is adopted, and palm print matchingcan be efficiently performed.
Description
technical field [0001] The present invention relates to the technical field of touch display and information recognition, in particular to a palm feature recognition device and recognition method. Background technique [0002] With the continuous development of touch screens (Touch Panel, TP), capacitive touch screens are gradually widely used in the field of terminal equipment. In existing capacitive touch devices, touch sensing signals are obtained based on mutual capacitance or self capacitance. In a mutual capacitance touch panel, the touch position is obtained by detecting the capacitance change between two electrodes. In a self-capacitive touch panel, the touch position is obtained by detecting the capacitance change between the electrode and the ground. [0003] The palmprint recognition technology based on capacitive touch has also been widely used due to its high stability of hand shape characteristics, which is not easy to change with external environment or phys...
