Abstract
(EN) A display device according to one embodiment of the present invention may comprise: a display panel; a first connecting film; and a second connecting film. The display panel may comprise first pads and second pads. The first connecting film may comprise: a first film including a first region connected to the first pads and having a first width, and a second region adjacent to the first region and having a second width that is different from the first width; and a first driving chip mounted on the first film. The second connecting film may comprise: a second film including a third area connected to the second pads and having a third width, and a fourth area adjacent to the third area and having a fourth width that is different from the third width and smaller than the second width; and a second driving chip mounted on the second film.
(FR) Selon un mode de réalisation de la présente invention, un dispositif d'affichage peut comprendre : un écran d'affichage ; un premier film de connexion ; et un second film de connexion. L'écran d'affichage peut comprendre des premiers plots et des seconds plots. Le premier film de connexion peut comprendre : un premier film comprenant une première zone connectée aux premiers plots et ayant une première largeur, et une deuxième zone adjacente à la première zone et ayant une deuxième largeur qui est différente de la première largeur ; et une première puce d'entraînement montée sur le premier film. Le second film de connexion peut comprendre : un second film comprenant une troisième zone connectée aux seconds plots et ayant une troisième largeur, et une quatrième zone adjacente à la troisième zone et ayant une quatrième largeur qui est différente de la troisième largeur et inférieure à la deuxième largeur ; et une seconde puce d'entraînement montée sur le second film.
(KO) 본 발명의 일 실시예에 따른 표시장치는 표시패널, 제1 연결필름, 및 제2 연결필름을 포함할 수 있다. 상기 표시패널은 제1 패드들 및 제2 패드들을 포함할 수 있다. 상기 제1 연결필름은 상기 제1 패드들에 연결되며 제1 폭을 갖는 제1 영역 및 상기 제1 영역과 인접하며 상기 제1 폭과 상이한 제2 폭을 갖는 제2 영역을 포함하는 제1 필름 및 상기 제1 필름에 실장된 제1 구동칩을 포함할 수 있다. 상기 제2 연결필름은 상기 제2 패드들에 연결되며 제3 폭을 갖는 제3 영역 및 상기 제3 영역과 인접하며 상기 제3 폭과 상이하며 상기 제2 폭보다 작은 제4 폭을 갖는 제4 영역을 포함하는 제2 필름 및 상기 제2 필름에 실장된 제2 구동칩을 포함할 수 있다.
