Description

섀도우마스크와 패널내면과의 거리 측정방법How to measure the distance between the shadow mask and the inside of the panel

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

제1도는 본 발명의 거리 측정방법에 사용되는 측정수단을 개략적으로 나타내는 전체 도면.1 is an overall view schematically showing measuring means used in the distance measuring method of the present invention.

제2도는 본 발명의 금속봉이 섀도우마스크를 통과하는 상태를 나타낸 도면.2 is a view showing a state in which the metal rod of the present invention passes through the shadow mask.

제3도는 본 발명의 금속봉이 섀도우마스크의 구멍을 통과할 때 나타나는 정전유도 현상에 의해 변화되는 전류와 시간과의 관계를 나타낸 도면.3 is a view showing the relationship between the current and the time changed by the electrostatic induction phenomenon that occurs when the metal rod of the present invention passes through the hole of the shadow mask.

Claims (1)

패널(P)의 섀도우마스크(S)를 조립한 상태에서 섀도우마스크(S)에 전류를 흘리고, 이 섀도우마스크(S)의 구멍속으로 전류계(1)와 연결된 금속봉(2)를 일정한 속도로 통과시켜 이때 정전유도 현상에 의해 발생된 전류가 금속봉(2)에 흐르는 시간과 금속봉(2)가 이동한 속도를 곱하여 Q치를 측정하는 섀도우마스크와 패널내면과의 거리 측정 방법.In the state where the shadow mask S of the panel P is assembled, a current flows through the shadow mask S, and the metal rod 2 connected to the ammeter 1 is passed through the hole of the shadow mask S at a constant speed. At this time, the shadow mask and the distance measurement method between the inner surface of the panel and the shadow mask to measure the Q value by multiplying the time that the current generated by the electrostatic induction phenomenon flows through the metal rod (2) and the moving speed of the metal rod (2). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
