An organic light emitting device (OLED) for a color video display. The OLED (10) is a layered structure formed on a substrate (100). A layer of light emitting organic material (300) is sandwiched between two conductive layers (200, 250) and placed on the substrate (100). Overlying the conductors (200, 250) and organic layer (300) is a transparent cover layer (500). The OLED (10) of the present invention includes an innovative microcavity enhancing structure (400), which restricts light emission in directions parallel to the substrate (100) and provides increased light output toward the viewer.
L'invention concerne un dispositif organique électroluminescent (OLED) pour visuel vidéo couleur. L'OLED (10) est une structure stratifiée formée sur un substrat (100). Une couche de matériau organique électroluminescent (300) est prise en sandwich entre deux couches conductrices (200, 250) et placée sur le substrat (100). Une couche de revêtement transparente (500) recouvre les conducteurs (200, 250) et la couche organique (300). Le dispositif (OLED) (10) de l'invention est amélioré grâce à une structure à microcavité (400) innovante qui restreint l'émission de lumière dans des directions parallèles au substrat (10) et permet une production de lumière accrue en direction de l'utilisateur.
