Abstract:
(EN) The present disclosure provides an organic electroluminescent device, an OLED substrate and a display device, belonging to the field of display technology, and being able to solve the problems of poor continuity in ink jet printing experiment and requirement for configuring a complex computer program between materials of different luminescent layers, which occur in the process of preparing a current organic electroluminescent device. The organic electroluminescent device of the present disclosure comprises a cathode, an anode and a functional layer located between the cathode and anode; the functional layer comprises a first light-emitting layer and a second light-emitting layer which are sequentially arranged in a direction away from the anode, the first light-emitting layer comprising a first blue light-emitting material, and the first light-emitting layer and the second light-emitting layer forming a composite product after the cathode and the anode are powered on, so as to emit light having a color different from blue.
(FR) La présente invention concerne un dispositif électroluminescent organique, un substrat OLED et un dispositif d'affichage, appartenant au domaine de la technologie d'affichage, et étant apte à résoudre les problèmes de faible continuité dans l'expérience d'impression à jet d'encre et l'exigence de configuration d'un programme d'ordinateur complexe entre des matériaux de différentes couches luminescentes, qui se produisent dans le processus de préparation d'un dispositif électroluminescent organique actuel. Le dispositif électroluminescent organique de la présente invention comprend une cathode, une anode et une couche fonctionnelle située entre la cathode et l'anode; la couche fonctionnelle comprend une première couche électroluminescente et une seconde couche électroluminescente qui sont disposées de manière séquentielle dans une direction à l'opposée de l'anode, la première couche électroluminescente comprenant un premier matériau électroluminescent bleu, et la première couche électroluminescente et la seconde couche électroluminescente formant un produit composite après que la cathode et l'anode sont alimentées, de manière à émettre une lumière ayant une couleur différente de celle du bleu.
(ZH) 本公开提供一种有机电致发光器件、OLED 基板和显示装置,属于显示技术领域,其可解决现有的有机电致发光器件在制备过程中存在的喷墨打印实验连续性低,且不同发光层材料之间需要设置复杂的电脑程序的问题。本公开的有机电致发光器件,包括阴极、阳极以及位于所述阴极和阳极之间的功能层;所述功能层包括在背离阳极的方向上依次设置的第一发光层和第二发光层,所述第一发光层包括第一蓝光发光材料,所述第一发光层和所述第二发光层在所述阴极和阳极通电后形成复合产物,以发出颜色异于蓝光的光线。
