Beschreibung
Zusammenfassung:	A data driving circuit of a display device comprises: a first receiving unit to receive a first image control signal from the outside when a power supply is initiated; a second receiving unit to receive a second image control signal in response to an activated data packet detection signal; and a data packet detecting unit to activate the data packet detection signal when a line starting field included in the first image control signal is detected. Accordingly, the present invention is able to prevent a malfunction by an overcurrent. 표시 장치의 데이터 구동회로는, 전원 공급이 개시될 때 외부로부터 제1 영상 제어 신호를 수신하는 제1 수신부, 활성화된 데이터 패킷 검출 신호에 응답해서 제2 영상 제어 신호를 수신하는 제2 수신부 및 상기 제1 영상 제어 신호에 포함된 라인 시작 필드가 검출될 때 상기 데이터 패킷 검출 신호를 활성화하는 데이터 패킷 검출부를 포함한다.
