Description

발광다이오드형 표시기 재생방법How to Play LED Display

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 7 세그먼트형의 LED형 표시기의 평면도,1 is a plan view of a 7-segment type LED indicator,

제2도는 7 세그먼트 애노우드 커먼형 LED형 표시기의 등가 회로도.2 is an equivalent circuit diagram of a 7 segment anode common LED type indicator.

Claims (2)

발광다이오드 표시기의 신호전류입력단들의 사이에 끼인 불순물을 제거하기 위하여, 합선된 입력단중의 일측단에 임펄스전류를 가하고, 그 타측단으로는 상기 임펄스 전류가 바이패스 접지되도록 함으로써, 순간 고전압에 의한 주울열에 의해 합선의 요인인 불순물이 소각되도록 하는 것을 특징으로 하는 발광다이오드형 표시기 재생방법.In order to remove impurities trapped between the signal current input terminals of the light emitting diode display, an impulse current is applied to one end of the short-circuit input stage, and the impulse current is bypassed to the other end thereof, thereby causing the joule caused by the momentary high voltage. A method of reproducing a light-emitting diode type display, characterized by incineration of impurities which are a factor of short circuit by heat. 제1항에 있어서, 발광다이오드의 각 신호입력단들(N개)중 두 개를 취하여 모든 두 개의 신호입력단들 사이에 nC2회의 고압 임펄스 전류를 순차적으로 가하는 것을 특징으로 하는 발광다이오드형 표시기 재생방법.2. A method according to claim 1, wherein two of the signal input terminals (N) of the light emitting diodes are taken and sequentially applied nC two high-voltage impulse currents between all two signal input terminals. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
