Patent ID: 8154539

Claim:
An active matrix apparatus comprising: a plurality of pixel circuits arranged in a matrix, each of the pixel circuits comprising an electroluminescent element, a thin film transistor for controlling light emission of the electroluminescent element, and a capacitor provided at a gate of the thin film transistor, to hold in the capacitor a voltage according to an input current signal and to emit light from the electroluminescent element based on the input current signal; a plurality of analog current signal generation circuits each comprising a thin film transistor for converting an input analog video signal to generate the input current signal which each of the pixel circuits inputs through a data line; a correction circuit for detecting the input current signal outputted though a signal output line from the plurality of analog current signal generation circuits, and for correcting, based on the detected current signal, the input analog video signal to be input into the analog current signal generation circuits; a switch unit for controlling connection between the outputs of the current signal generation circuits and the current signal output line; a breaking unit, arranged between the switch unit and the plurality of pixel circuits, for shutting down a current flowing from the current signal generation circuits into each of the pixel circuits; and a logic circuit for controlling connection between the switch unit and the braking unit, wherein during detecting the input current signal by the correction circuit, the logic circuit supplies the braking unit with a signal for shutting down the current flowing from the switch unit into the pixel circuits, and supplies the switch unit with a signal for connecting the outputs of the current signal generation circuits with the current signal output line.
