Abstract: front page image
(EN) A light-emitting element display device and a manufacturing method therefor are disclosed. According to the present invention, the light-emitting element display device comprises a light-emitting element array including a plurality of light-emitting elements mutually connected to adjacent light-emitting elements by a plurality of first contact electrodes formed in parallel to each other in a first direction and a plurality of second contact electrodes formed in parallel to each other in a second direction that is orthogonal to the first direction. Herein, a resistance state (switch on/switch off) of each switching element or switching region can be changed and stored by forming a switching element or a switching region formed of a resistance change material between a first contact electrode and a light-emitting element or between a second contact electrode and the light-emitting element, and adjusting a voltage to be applied between the first contact electrode and the second contact electrode. Therefore, according to the present invention, the light-emitting element array can be driven through only changing of a resistance state of a switching element or a switching region, by adjusting a voltage to be applied between a first contact electrode and a second contact electrode, thereby: enabling a display to be driven at low power and at low costs; and a thermal stability problem and a misalign problem of a bump metal, which occur while bonding a conventional light-emitting array on a CMOS substrate by a flip chip scheme, to be solved.
(FR) L'invention concerne un dispositif d'affichage électroluminescent et son procédé de fabrication. Selon l'invention, le dispositif d'affichage d'élément électroluminescent comporte un réseau d'éléments électroluminescents comprenant une pluralité d'éléments électroluminescents connectés à des éléments électroluminescents adjacents par une pluralité de premières électrodes de contact, formées parallèlement les unes aux autres dans une première direction, et par une pluralité de secondes électrodes de contact, formées parallèlement les unes aux autres dans une seconde direction orthogonale à la première direction. Dans la présente invention, un état de résistance (passant/non passant) de chaque élément ou région de commutation peut être modifié et stocké par formation d'un élément ou d'une région de commutation constitué d'un matériau à variation de résistance entre une première ou une seconde électrode de contact et un élément électroluminescent, et par réglage d'une tension à appliquer entre les première et seconde électrodes de contact. Par conséquent, le réseau d'éléments électroluminescents peut être commandé simplement par l'intermédiaire du changement d'un état de résistance d'un élément ou d'une région de commutation, par réglage d'une tension à appliquer entre les première et seconde électrodes de contact, ce qui permet à la fois à un dispositif d'affichage d'être commandé à faible puissance et à faibles coûts, et de palier les problèmes de stabilité thermique et de défaut d'alignement d'un métal à bosse qui surviennent lors de la liaison d'un réseau électroluminescent classique sur un substrat CMOS par un schéma de puce retournée.
(KO) 본 발명은 발광 소자 디스플레이 장치 및 이의 제조 방법을 공개한다. 본 발명의 발광 소자 디스플레이 장치는, 제 1 방향으로 서로 평행하게 형성된 복수의 제 1 접촉 전극 및 제 1 방향과 직교하는 제 2 방향으로 서로 평행하게 형성된 복수의 제 2 접촉 전극에 의해서 인접하는 발광 소자들과 서로 연결되는 복수의 발광 소자를 포함하는 발광 소자 어레이로 구성된다. 이 때, 제 1 접촉 전극과 발광 소자 사이에 또는 제 2 접촉 전극과 발광 소자 사이에, 저항 변화 물질로 구성되는 스위칭 소자 또는 스위칭 영역을 형성하고, 제 1 접촉 전극과 제 2 접촉 전극 사이에 안가되는 전압을 조절하여, 각 스위칭 소자 또는 스위치 영역의 저항 상태(스위치 온/스위치 오프)를 변경 및 저장할 수 있다. 따라서, 본 발명은 제 1 접촉 전극 및 제 2 접촉 전극 간에 인가되는 전압을 조절하여 스위칭 소자 또는 스위칭 영역의 저항 상태를 변경하는 것만으로 발광 소자 어레이를 구동이 가능하므로, 저전력 및 저비용으로 디스플레이의 구동이 가능하고, 종래 기술의 발광 소자 어레이를 플립 칩 방식으로 CMOS 기판위에 접합하면서 발생하는 bump 메탈의 열적 안정성 문제 및 misalign 문제를 해소하였다.
