Abstract:
A fingerprint sensor is provided and includes substrate; sensor electrodes arranged on substrate; first switches coupled to sensor electrodes; organic layer covering sensor electrodes; control line drive circuit in a first direction; signal line drive circuit in a second direction orthogonal to the first direction; signal lines coupled to the first switches; control lines coupling first switches to control line drive circuit; sensor drive electrode surrounding sensor electrodes; second switches between signal line drive circuit and signal lines; first number of third switches between signal line drive circuit and first number of second switches, wherein surface of organic layer is lower than sensor drive electrode, and wherein first number is less than number of all second switches.
