Description

액정 표시기의 검사방법Inspection method of liquid crystal display

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

제1도는 매트릭스형 액정 표시기에 있어서의 불량상태를 나타낸 도면,1 is a view showing a bad state in a matrix type liquid crystal display,

제2도는 7 세그먼트형 액정 표시기에 있어서의 불량 상태를 나타낸 도면.2 is a view showing a bad state in a seven segment liquid crystal display.

Claims (1)

액정표시기에 나타난 특정패턴을 확대 촬영하는 단계와; 각 수광셀 또는 인접된 수광셀들의 그룹들로 부터 얻어진 매트릭스 또는 세그먼트의 부분적 휘도값을 일정 레벨치를 기준으로 하여2진의 디지틀값으로 순차변환하는 단계와; 상기 각 수광셀 또는 수광셀그룹별로 변환된 2진 디지틀 값을 각각의 수광셀 또는 각각의 수광셀그룹별로 대응되게 기설정된2지의 테이터값과 비교판단하는 단계와; 상기 순차변환된 디지틀값을 그 전후의 디지틀값과 연속비교하는 단계를 갖는 그 전후의 디지틀값과 연속비교하는 단계를 갖는 것을 특징으로 하는 액정 표시기의 검사방법.Photographing a specific pattern displayed on the LCD; Sequentially converting partial luminance values of the matrix or segment obtained from each light receiving cell or groups of adjacent light receiving cells into binary digital values based on a predetermined level value; Comparing the binary digital value converted for each light receiving cell or light receiving cell group with data values of two preset cells corresponding to each light receiving cell or light receiving cell group; And continuously comparing the sequentially converted digital value with the digital value before and after that, and with the digital value before and after the sequence value. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
