Abstract: A radio-frequency (RF) communication device having a near field communication (NFC) function includes a first detection mode circuit configured to output an RF input signal received by an antenna as a first RF signal while the first detection mode circuit is enabled, and a second detection mode circuit configured to amplify the RF input signal and output the amplified RF input signal as a second RF signal while the second detection mode circuit is enabled. The first detection mode circuit is enabled during a first time period, and the second detection mode circuit is enabled during a second time period. The second time period is shorter than the first time period. The first and second detection mode circuits are enabled alternately and repeatedly.

Abstract: A semiconductor device is disclosed. The semiconductor device includes a transceiver including an amplifier region configured to output a data signal to a source line connected to a pixel during a first period and receive a detection signal from a touch electrode during a second period different from the first period, and configured to generate the data signal based on input data; and a driving controller configured to generate the data based on input image data, outputting the data to the transceiver, and generate a touch signal based on the detection signal.
