Abstract A display driver comprises a driver circuit and a detection controller. The driver circuit is configured so as to drive a display panel according to display information. The display panel defines a detection area. A detection controller interface circuit is configured so as to transmit an output vertical synchronizing signal to a proximity detection controller. The proximity detection controller is configured so as to generate position information of an input object based at least in part on a result signal received from a sensor electrode disposed in the detection area. The output vertical synchronizing signal comprises encoding the display information in the output vertical synchronizing signal. 디스플레이 드라이버는 드라이버 회로와 감지 제어기를 포함한다. 드라이버 회로는 디스플레이 정보에 따라 디스플레이 패널을 구동하도록 구성된다. 디스플레이 패널은 감지 구역을 정의한다. 감지 제어기 인터페이스 회로는 출력 수직 동기 신호를 근접 감지 제어기로 송신하도록 구성된다. 근접 감지 제어기는 감지 구역에 배치된 센서 전극으로부터 수신된 결과 신호에 적어도 부분적으로 기초하여 입력 객체의 위치 정보를 생성하도록 구성된다. 출력 수직 동기 신호는 출력 수직 동기 신호에서 디스플레이 정보를 인코딩하는 것을 포함한다.
