Title
(KO) 빠른 터치 반응성을 가지는 터치 및 디스플레이 제어 장치, 이를 포함하는 디스플레이 장치 및 이의 구동 방법
Abstract
(KO) 터치 및 디스플레이 제어 장치는 터치 스크린 컨트롤러 및 디스플레이 드라이버를 포함한다. 터치 스크린 컨트롤러는 터치 스크린 패널로부터 터치 센싱 신호를 수신하고, 터치 센싱 신호에 기초하여 터치 원시(raw) 데이터를 생성하며, 터치 원시 데이터에 기초하여 터치 좌표 정보 및 제1 터치 속성 정보를 추출한다. 디스플레이 드라이버는 외부의 호스트 프로세서로부터 원본 영상을 수신하고, 터치 스크린 컨트롤러로부터 터치 좌표 정보 및 제1 터치 속성 정보를 직접 수신하고, 터치 좌표 정보 및 제1 터치 속성 정보를 누적하여 생성된 터치 궤적 정보를 저장하는 메모리를 포함하고, 터치 궤적 정보에 기초하여 원본 영상과 함께 표시될 터치 영상을 내부적으로 생성하고, 원본 영상과 터치 영상을 합성하여 합성 영상을 생성하며, 합성 영상을 표시하도록 디스플레이 패널을 제어한다.
