Abstract: front page image
(EN)A reflective multi-color electrophoretic display device according to one embodiment of the present invention comprises: a first substrate which provides a display surface, and a second substrate which opposes said first substrate; a plurality of cavities which are formed between said first and second substrates; transparent fluids which fill said plurality of cavities; color electrophoretic particles which are respectively dispersed in cavities that constitute color sub pixels among said cavities and have colors corresponding to said color sub pixels, and white electrophoretic particles which have an electrophoretic mobility different from that of said color electrophoretic particles; black layers which are the background of said color sub pixels on said second substrate; and a plurality of electrodes which selectively disperse one kind of particle of said electrophoretic particles toward said display surface, or collect all of said electrophoretic particles such that the electrophoretic particles are not seen from said display surface.
(FR)La présente invention concerne un dispositif d'affichage électrophorétique multicolore réfléchissant qui comprend : un premier substrat qui fournit une surface d'affichage, et un second substrat qui est opposé audit premier substrat ; une pluralité de cavités qui sont formées entre lesdits premier et second substrats ; des fluides transparents qui remplissent ladite pluralité de cavités ; des particules électrophorétiques couleurs qui sont respectivement dispersées dans des cavités qui constituent des sous-pixels couleurs parmi lesdites cavités et possèdent des couleurs qui correspondent auxdits sous-pixels couleurs, et des particules électrophorétiques blanches qui possède une mobilité électrophorétique différente de celle desdites particules électrophorétiques couleurs ; des couches noires qui sont l'arrière-plan desdits sous-pixels couleurs sur ledit second substrat ; et une pluralité d'électrodes qui dispersent sélectivement un type de particule desdites particules électrophorétiques vers ladite surface d'affichage, ou collectent toutes lesdites particules électrophorétiques de sorte que les particules électrophorétiques ne soient pas vues à partir de ladite surface d'affichage.
(KO)본 발명의 일 실시예에 따른 반사형 멀티 컬러 전기 영동 디스플레이 장치는, 디스플레이면을 제공하는 제 1 기판 및 상기 제 1 기판에 대향하는 제 2 기판; 상기 제 1 및 제 2 기판들 사이에 형성된 복수의 캐비티들; 상기 복수의 캐비티들 내에 충전되는 투명 유체; 상기 캐비티들 중 컬러 서브 픽셀을 구성하는 캐비티에 각각 분산되고 상기 컬러 서브 픽셀에 대응하는 컬러를 갖는 컬러 전기 영동 입자들 및 상기 컬러 전기 영동 입자들과 다른 전기 영동 이동도를 갖는 백색 전기 영동 입자들; 상기 제 2 기판측의 상기 컬러 서브 픽셀들의 배경이 되는 흑색층; 및 상기 전기 영동 입자들 중 어느 한 종류의 입자들을 상기 디스플레이면측으로 선택적으로 분산시키거나, 상기 디스플레이면으로부터 보이지 않도록 상기 전기 영동 입자들 모두를 수집하기 위한 복수의 전극들을 포함한다.
