Abstract
(EN)
A flexible transparent LED display of a LED electro-optical panel and a method for manufacturing the same are disclosed. The flexible transparent LED display of the LED electro-optical panel adopts a flexible transparent film metal pattern circuit equipped with three lines of a (+) electrode line, a data line and a (-) electrode line, in which a substrate PCB is not used, and in one unit package provided at each point of a matrix structure connected to the flexible transparent film metal pattern circuit, an operation circuit equipped with a 1R1G1B LED chip and a driver IC is continuously arranged in series and in parallel. The flexible transparent LED display of the LED electro-optical panel of the present invention does not use a heat sink for solving the heat generation problem generated during the operation of the 1R1G1B LED chip, and performs self-dispersion heat generation in the flexible transparent film metal pattern circuit having flexibility, thereby having an effect of extending the lifetime of the LED chip and stably maintaining the brightness thereof.

L'invention concerne un afficheur à LED transparent souple d'un panneau électro-optique à LED et son procédé de fabrication. L'afficheur à LED transparent souple du panneau électro-optique à LED adopte une configuration de circuit métallique en film transparent souple équipé de trois lignes dont : une ligne d'électrode (+), une ligne de données et une ligne d'électrode (-), laquelle n'utilise pas un circuit imprimé faisant substrat. Dans un boîtier unitaire disposé au niveau de chaque point d'une structure en matrice reliée à la configuration de circuit métallique en film transparent souple, un circuit de fonctionnement équipé d'une puce de LED 1R1G1B et un circuit intégré d'attaque sont disposés continuellement en série et en parallèle. L'afficheur à LED transparent souple du panneau électro-optique à LED selon la présente invention n'utilise pas de dissipateur thermique pour résoudre le problème de la chaleur générée pendant le fonctionnement de la puce de LED 1R1G1B, et réalise une génération de chaleur à auto-dispersion dans la configuration de circuit métallique en film transparent souple ayant une flexibilité, ce qui a pour effet de prolonger la durée de vie de la puce de LED et de maintenir sa luminosité stable.

LED 전기 광학 판넬의 플렉시블 투명 LED 디스플레이 및 그 제조 방법이 개시된다. LED 전기 광학 판넬의 플렉시블 투명 LED 디스플레이는 (+)전극선, 데이터 라인, (-)전극선의 3선이 구비되는 플렉시블 투명 필름 메탈 패턴(Flexible Transparent Film Metal Pattern) 회로를 적용하며, 기판 PCB를 사용하지 않고, 플렉시블 투명 필름 메탈 패턴 회로와 연결되는 매트릭스 구조의 각 지점 마다 구비되는 하나의 단위 패키지들에서는 드라이버 IC와 1R1G1B LED 칩을 장착하는 동작회로를 직병렬로 연속적으로 구성하며, 1R1G1B LED 칩이 동작 중에 발생되는 발열 문제를 해결하기 위한 히트싱크를 사용하지 않으며, 유연성을 갖는 플렉시블 투명 필름 메탈 패턴 회로에서 자체적으로 분산 발열하여 LED 칩의 수명 연장 및 밝기를 안정적으로 유지하는 효과가 있다.
