Abstract:
(EN) The present invention relates to a method for manufacturing a transparent substrate, and to an LED display board using the transparent substrate. More particularly, the present invention relates to a method for manufacturing a transparent substrate, in which a glass surface is screen-printed with transparent conductive ink, and sequentially sintered in air and nitrogen environments to reduce surface resistance and improve light transmittance. The method for manufacturing a transparent substrate according to the present invention comprises a step of screen-printing one side of a transparent glass with transparent conductive ink containing conductive nanopowder as a filler to pattern a conductive film electrode onto one side of the glass, a first sintering step of heating the glass which is patterned with the conductive film electrode by the screen-printing, in the air, to sinter the conductive film electrode, and a second sintering step of heating the glass on which the conductive film electrode is firstly sintered in a nitrogen gas to sinter the conductive film electrode. The LED display board using the transparent substrate according to the present invention is configured such that LEDs are arranged on one surface of the transparent substrate on which the conductive film electrode is formed by the above-described method, and said LEDs are connected to the conductive film electrode.
(FR) La présente invention concerne un procédé de fabrication d'un substrat transparent et un panneau d'affichage à DEL utilisant le substrat transparent. Plus précisément, la présente invention concerne un procédé de fabrication d'un substrat transparent dans lequel une surface en verre est sérigraphiée avec une encre conductrice transparente puis séquentiellement frittée dans des environnements d'air et d'azote de façon à réduire la résistance de la surface et à améliorer la transmittance. Le procédé de fabrication d'un substrat transparent d'après la présente invention comprend une étape consistant à sérigraphier un côté d'un verre transparent avec une encre conductrice transparente contenant une nanopoudre conductrice faisant office de matière de remplissage de façon à modeler une électrode à film conducteur sur un côté du verre, une première étape de frittage consistant à chauffer le verre qui est modelé avec l'électrode à film conducteur par la sérigraphie dans l'air de façon à fritter l'électrode à film conducteur et une seconde étape de frittage consistant à chauffer le verre sur lequel l'électrode à film conducteur a préalablement été frittée dans l'azote de façon à fritter l'électrode à film conducteur. Le panneau d'affichage à DEL utilisant le substrat transparent d'après la présente invention est conçu de telle manière que les DEL sont disposées sur une surface du substrat transparent sur laquelle l'électrode à film conducteur est formée selon le procédé susmentionné, lesdites DEL étant connectées à l'électrode à film conducteur.
(KO) 본 발명은 투명기판의 제조 방법 및 그 투명기판을 이용한 엘이디 전광판에 관한 것으로, 보다 상세하게는 글라스면에 투명도전성 잉크로 스크린 인쇄한 후 대기중과 질소환경에서 순차적으로 소결시킴으로써 표면저항을 감소시키고 광투과율을 향상시킨 투명기판의 제조 방법 및 그 투명기판을 이용한 전광판에 관한 것이다. 본 발명에 따른 투명기판의 제조 방법은, 투명한 글라스의 일면에 도전성초미분이 필라로 함유된 투명도전성 잉크로 스크린 인쇄하여 도전막 전극을 패터닝시키는 스크린인쇄단계와, 스크린 인쇄로 도전막 전극이 패터닝된 글라스를 대기중에서 가열하여 도전막 전극을 소성시키는 1차소성단계와, 도전막 전극이 1차로 소성된 글라스를 질소가스중에서 가열하여 도전막 전극을 소성시키는 2차소성단계를 포함하여 구성된 것을 특징으로 하며, 본 발명에 따른 투명기판을 이용한 엘이디 전광판은, 상기의 방법으로 도전막 전극이 형성된 투명기판의 일면에 엘이디가 배열되어 그 도전막 전극과 연결되도록 부착된 것을 특징으로 한다.
