Abstract: A pixel circuit includes a sensing block, a stimulation block, a first line control circuit, and a second line control circuit. The sensing block outputs biometric data of a biosignal in response to a first selection signal. The stimulation block radiates a stimulation signal in response to a second selection signal. The first line control circuit outputs the first selection signal for selecting the sensing block as a target sensing block, and outputs the second selection signal for selecting the stimulation block as a target stimulation block. The second line control circuit processes characteristic data associated with the biometric data and the stimulation signal.
