액정 판넬의 표시 특성 평가 장치Apparatus for evaluating display characteristics of liquid crystal panel

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 따라 액정 판넬의 표시 특성을 평가하는 장치를 보인 도면.1 shows an apparatus for evaluating display characteristics of a liquid crystal panel according to the present invention.

Claims (1)

선택된 모드와 문자 크기에 따라서 액정 판넬(50)에 표시되는 데이터를 콘트롤 하는 LCD 콘트롤러(10)에서 출력되는 세그먼트 구동용 직렬 데이터(S2)를 데어터 쉬프트 클럭 펄스(S1)에 의해서 내부에 있는 레지스터에 저장하는 판넬 세그먼트 드라이브단(30)과, 상기, 판넬 세그먼트 드라이브단(30)에 인가되는 데이터쉬푸트 클럭펄스(S1)를 가변하여 판넬 세그먼트 드라이브단(30)에서 출력되는 데이터수를 확장하는 래취펄스 가변부(20)와, 상기한 LCD 콘트롤러(10)에서 출력되는 판넬 공통 라인의 스캔 스타트 신호(S3)와 판넬 세그먼트 드라이브단(30)내의 레지스터에 저장된 데이터를 액정 판넬(50)에 인가하는 시간에 맞게 공통라인을 스캐닝 시켜주는 공통 쉬프트 클럭신호(S4)를 받아 액정 판넬(50)의 공통라인을 드라이브하는 판넬라인 드라이브단(40)으로 구성됨을 특징으로 하는 액정 판넬의 표시 특성 평가 장치.The segment driving serial data S2 output from the LCD controller 10 controlling the data displayed on the liquid crystal panel 50 in accordance with the selected mode and the character size is transferred to the internal register by the data shift clock pulse S1. A latch to expand the number of data output from the panel segment drive stage 30 by varying the panel segment drive stage 30 to be stored and the data shift clock pulse S1 applied to the panel segment drive stage 30. A pulse start unit 20 and a scan start signal S3 of a panel common line output from the LCD controller 10 and data stored in a register in the panel segment drive stage 30 are applied to the liquid crystal panel 50. Consists of a panel line drive stage 40 for receiving a common shift clock signal S4 for scanning a common line in time to drive a common line of the liquid crystal panel 50. Display characteristics of the liquid crystal panel evaluation device, characterized by. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
