Abstract:
(EN) A manufacturing method of an OLED display device, and an OLED display device. The manufacturing method of an OLED display device comprises: before forming an OLED light-emitting layer (400), printing an electrically-conductive material solution to respective pixel regions (101) of a TFT substrate (100), and drying the same to remove a solvent therein so as to obtain an electrically-conductive layer (300) having a flat surface, the electrically-conductive layer (300) and a pixel electrode (130) at the TFT substrate (100) together serving as a positive electrode structure; and printing an OLED light-emitting material solution to the respective pixel regions (101) of the TFT substrate (100), and drying the same to form an OLED light-emitting layer (400) above the electrically-conductive layer (300). Since the surface of the electrically-conductive layer (300) is flat, the OLED light-emitting layer (400) formed thereon by means of printing has a uniform thickness, such that a resulting OLED display device can emit uniform light, thereby effectively enhancing display performance of the OLED display device.
(FR) L'invention concerne un dispositif d'affichage DELO, et un dispositif d'affichage DELO. Le procédé de fabrication d'un dispositif d'affichage DELO consiste : avant la formation d'une couche électroluminescente DELO (400), à imprimer une solution de matériau électroconducteur à des régions de pixel respectives (101) d'un substrat TFT (100), et à la sécher pour éliminer un solvant en son sein de manière à obtenir une couche électriquement conductrice (300) ayant une surface plate, la couche électriquement conductrice (300) et une électrode de pixel (130) au niveau du substrat TFT (100) servant ensemble de structure d'électrode positive ; et à imprimer une solution de matériau électroluminescent DELO aux régions de pixel respectives (101) du substrat TFT (100), et à la sécher pour former une couche électroluminescente DELO (400) au-dessus de la couche électriquement conductrice (300). Étant donné que la surface de la couche électriquement conductrice (300) est plate, la couche électroluminescente DELO (400) formée en son sein au moyen d'une impression a une épaisseur uniforme, de telle sorte qu'un dispositif d'affichage DELO résultant puisse émettre une lumière uniforme, améliorant ainsi efficacement les performances d'affichage du dispositif d'affichage DELO.
(ZH) 一种OLED显示器的制作方法及OLED显示器。该OLED显示器的制作方法在制作OLED发光层(400)之前,在TFT基板(100)的多个像素区域(101)内分别打印溶液态的导电材料并对其进行干燥去除其中的溶剂,从而得到表面平坦的导电层(300),由导电层(300)及TFT基板(100)上的像素电极(130)共同作为阳极结构,而后在TFT基板(100)的多个像素区域(101)内分别打印溶液态的OLED发光材料并对其进行干燥形成位于导电层(300)上OLED发光层(400),由于导电层(300)表面平坦,位于导电层(300)上通过打印制得的OLED发光层(400)膜厚均匀,使制得的OLED显示器发光均匀,有效地提升了OLED显示器的显示效果。
