Title (EN) COLOUR DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE COULEUR
(ZH) 彩色显示器件
Abstract:
(EN) A colour display device, comprising: a substrate (1), a positive electrode (21) formed on the substrate (1), a thin film transistor array (23) formed on the positive electrode (21), a hole injection layer (24) formed on the thin film transistor array (23), a hole transport layer (25) formed on the hole injection layer (24), a white light light-emitting layer (26) formed on the hole transport layer (25), an electron transport layer (27) formed on the white light light-emitting layer (26), a negative electrode (28) formed on the electron transport layer (27), a cover plate (3) arranged above the negative electrode (28) and fitted with the substrate (1), a colour conversion layer (4) formed on the inner side of the cover plate (3), and sealing frame glue (6) bonding the substrate (1) to the cover plate (3). The colour conversion layer (4) comprises a blue sub-pixel area (41), a green sub-pixel area (43), a red sub-pixel area (45) and a white sub-pixel area (47) arranged at intervals, the blue sub-pixel area (41) being formed with a blue light filter layer, the green sub-pixel area (43) being formed with a green light filter layer or a green light conversion layer, the red sub-pixel area (45) being formed with a red light filter layer or a red light conversion layer, the white sub-pixel area (47) not being provided with a filter layer.
(FR) L'invention concerne un dispositif d'affichage couleur, comprenant : un substrat (1), une électrode positive (21) formée sur le substrat (1), un réseau (23) de transistors en couche mince formé sur l'électrode positive (21), une couche (24) d'injection de trous formée sur le réseau (23) de transistors en couche mince, une couche (25) de transport de trous formée sur la couche (24) d'injection de trous, une couche (26) émettrice de lumière blanche formée sur la couche (25) de transport de trous, une couche (27) de transport d'électrons formée sur la couche (26) émettrice de lumière blanche, une électrode négative (28) formée sur la couche (27) de transport d'électrons, une plaque de recouvrement (3) disposée au-dessus de l'électrode négative (28) et ajustée avec le substrat (1), une couche (4) de conversion de couleur formée sur le côté interne de la plaque de recouvrement (3) et une colle (6) de cadre de scellage liant le substrat (1) à la plaque de recouvrement (3). La couche (4) de conversion de couleur comprend une zone de sous-pixel bleu (41), une zone de sous-pixel vert (43), une zone de sous-pixel rouge (45) et une zone sous-pixel blanc (47) disposées à des intervalles, la zone de sous-pixel bleu (41) étant formée avec une couche de filtre de lumière bleue, la zone de sous-pixel vert (43) étant formée avec une couche de filtre de lumière verte ou une couche de conversion de lumière verte, la zone de sous-pixel rouge (45) étant formée avec une couche de filtre de lumière rouge ou une couche de conversion de lumière rouge, la zone de sous-pixel blanc (47) n'étant pas munie d'une couche de filtre.
(ZH) 一种彩色显示器件,包括:基板(1)、形成于基板(1)上的阳极(21)、形成于阳极(21)上的薄膜晶体管阵列(23)、形成于薄膜晶体管阵列(23)上的空穴注入层(24)、形成于空穴注入层(24)上的空穴传输层(25)、形成于空穴传输层(25)上的白光发光层(26)、形成于白光发光层(26)上的电子传输层(27)、形成于电子传输层(27)上的阴极(28)、设于阴极(28)上方并与基板(1)贴合的盖板(3)、形成于盖板(3)内侧的色彩转换层(4)、及粘结基板(1)与盖板(3)的密封框胶(6),其中,所述色彩转换层(4)包括间隔设置的蓝色子像素区域(41)、绿色子像素区域(43)、红色子像素区域(45)与白色子像素区域(47),所述蓝色子像素区域(41)形成有蓝光过滤层,所述绿色子像素区域(43)形成有绿光过滤层或绿光转换层,所述红色子像素区域(45)形成有红光过滤层或红光转换层,所述白色子像素区域(47)未设置过滤层。
