Abstract:
Various aspects or embodiments of fingerprint sensing are described, for use in fingerprint sensing, for example, over a portion or whole of a screen of a computing device, such as smart phones, tablet computers or other information processing devices. An electronic module, computing apparatus, and a panel are provided. The electronic module includes a slew rate configuring circuit to generate and transmit at least one output signal to a gate on array (GOA) circuit of the panel; and a fingerprint sensing control circuit, coupled to fingerprint sensing elements of the panel, to generate and transmit control signals to the GOA circuit, wherein the fingerprint sensing control circuit controls the GOA circuit to generate reset signals according to the at least one output signal to reset the fingerprint sensing elements respectively and the slew rate configuring circuit controls a slew rate of a falling edge of each reset signal.
