Title (EN) OLED DEVICE AND METHOD FOR MANUFACTURING SAME, AND OLED DISPLAY PANEL
(FR) DISPOSITIF DELO ET SON PROCÉDÉ DE FABRICATION, ET ÉCRAN D'AFFICHAGE DELO
(ZH) OLED器件及其制备方法、OLED显示面板
Abstract: front page image
(EN)An OLED device and a method for manufacturing same, and an OLED display panel. The OLED device comprises an anode (1) disposed on a substrate (100), a cathode (2), a hole transport layer (5) and an electron transport layer (6) which are disposed between the anode (1) and the cathode (2), and at least two light emitting layers (3, 4) disposed between the hole transport layer (5) and an electron transport layer (6), wherein the at least two light emitting layers (3, 4) emit white light The OLED device further comprises an electron blocking layer (7) disposed between the electron transport layer (6) and the at least two light emitting layers (3, 4). The color stability of the OLED device is improved.
(FR)L'invention porte sur un dispositif DELO et son procédé de fabrication, et sur un écran d'affichage DELO. Le dispositif DELO comprend une anode (1) disposée sur un substrat (100), une cathode (2), une couche de transport de trous (5) et une couche de transport d'électrons (6) qui sont disposées entre l'anode (1) et la cathode (2), et au moins deux couches électroluminescentes (3, 4) disposées entre la couche de transport de trous (5) et la couche de transport d'électrons (6), lesdites deux couches électroluminescentes (3, 4) émettant de la lumière blanche. Le dispositif DELO comprend en outre une couche de blocage d'électrons (7) disposée entre la couche de transport d'électrons (6) et lesdites deux couches électroluminescentes (3, 4). La stabilité de couleur du dispositif DELO est améliorée.
(ZH)一种OLED器件及其制备方法、OLED显示面板,该OLED器件包括设置在衬底(100)上的阳极(1)、阴极(2)、设置在阳极(1)和阴极(2)之间的空穴传输层(5)和电子传输层(6),以及设置在空穴传输层(5)和电子传输层(6)之间的至少两个发光层(3,4),其中,该至少两个发光层(3,4)发白光;该OLED器件还包括设置在电子传输层(6)和该至少两个发光层(3,4)之间的电子阻挡层(7)。OLED器件的色稳定性得到提高。
