Abstract: front page image
(EN)The present invention relates to an electrophoretic display with an integrated touch screen which uses an infrared optical sensor system. An electrophoretic display, according to one embodiment of the present invention, comprises: a substrate having image gate wires and image signal wires intersecting one another; an image switching TFT electrically connected to the image gate wires and to the image signal wires; a sensing TFT for sensing infrared rays and generating an infrared ray sensing signal; an output switching TFT connected to the sensing TFT, for outputting position information from the infrared ray sensing signal; an infrared filter insulation layer formed on the substrate to cover the sensing TFT, for transmitting only infrared rays; a pixel electrode which is formed on the infrared ray filter insulation layer and which is electrically connected to the image switching TFT; an electrophoretic film which is formed on the pixel electrode, which has a plurality of micro capsules including pigment particles with positive and negative electrical charges; and a common electrode, which is formed on the electrophoretic film.
(FR)La présente invention porte sur un dispositif d'affichage électrophorétique à écran tactile intégré qui utilise un système capteur optique infrarouge. Le dispositif d'affichage électrophorétique, selon un mode de réalisation de la présente invention, comprend : un substrat ayant des fils de synchronisation d'image et des fils de signal d'image se croisant mutuellement; un transistor à couches minces (TFT) de commutation d'image électriquement connecté aux fils de synchronisation d'image et aux fils de signal d'image; un TFT de détection, qui détecte des rayons infrarouges, pour générer un signal de détection de rayons infrarouges; un TFT de commutation de sortie connecté au TFT de détection, pour délivrer des informations de position issues du signal de détection de rayons infrarouges; une couche d'isolation de filtre infrarouge formée sur le substrat pour couvrir le TFT de détection, pour transmettre seulement des rayons infrarouges; une électrode de pixel formée sur la couche d'isolation de filtre de rayons infrarouges et qui est électriquement connectée au TFT de commutation d'image; un film électrophorétique formé sur l'électrode de pixel, qui comprend une pluralité de microcapsules contenant des particules de pigment ayant des charges électriques positives et négatives; et une électrode commune, qui est formée sur le film électrophorétique.
(KO)본 발명은 적외선 광센서 방식을 이용한 터치스크린 내장형 전자영동 표시장치에 관한 것이다. 본 발명에 따른 전자영동 표시장치의 일 구성은 영상 게이트배선과 영상 신호배선이 교차 형성되어 있는 기판과 영상 게이트배선과 영상 신호배선과 전기적으로 연결된 영상스위칭 TFT를 구비한다. 그리고 적외선을 감지하여 적외선 감지신호를 발생하는 센싱 TFT와 센싱 TFT와 연결되어 적외선 감지신호로부터 위치정보를 출력하는 출력스위칭 TFT를 구비한다. 그리고 센싱 TFT가 덮이도록 기판 상에 형성되며 적외선만을 투과시키는 적외선 필터 절연층과 적외선 필터 절연층 상에 형성되며 상기 영상스위칭 TFT와 전기적으로 연결되는 화소전극을 구비한다. 그리고 화소전극 상에 형성되며 양성 및 음성으로 대전된 안료 입자들을 포함하는 다수의 미소 캡슐들을 구비하는 전자영동필름과 전자영동필름 상에 형성되는 공통전극을 구비한다.
