Abstract: The master device includes a first pad connected to a slave device through a first wire; a second pad connected to the slave device through a second wire; and a communication interface to transmit a communication control signal to the slave device through the first pad, and, through the second pad, to transmit a first data signal synchronized with the communication control signal to the slave device and to receive a second data signal synchronized with the communication control signal from the slave device. The first data signal is transmitted to the slave device by the master device in a write mode and the second data signal is transmitted to the master device by the slave device in a read mode. The communication interface is configured to start the read mode by transiting the communication control signal from a first voltage level to a second voltage level while the second pad has a predetermined voltage level.

Abstract: A display device is disclosed that includes a display panel, a scan driver, a panel driving circuit, and a readout circuit. The display panel includes a pixel that includes a light emitting element and a sensor that includes a light sensing element. The scan driver outputs a scan signal for driving the pixel and the sensor in response to a scan control signal. The panel driving circuit outputs the scan control signal. The readout circuit generates switching signals based on the scan control signal and outputs a fingerprint sensing signal corresponding to a sensing signal received from the sensor in response to the switching signals.
