Title (EN) ORGANIC LIGHT EMITTING DIODE DISPLAY SUBSTRATE, ORGANIC LIGHT EMITTING DIODE DISPLAY APPARATUS, AND METHOD OF FABRICATING ORGANIC LIGHT EMITTING DIODE DISPLAY SUBSTRATE
(FR) SUBSTRAT D'AFFICHAGE À DIODES ÉLECTROLUMINESCENTES ORGANIQUES, APPAREIL D'AFFICHAGE À DIODES ÉLECTROLUMINESCENTES ORGANIQUES ET PROCÉDÉ DE FABRICATION DE SUBSTRAT D'AFFICHAGE À DIODES ÉLECTROLUMINESCENTES ORGANIQUES
Abstract:
(EN) A method of fabricating an organic light emitting diode display substrate having a subpixel region(201) and an inter-subpixel region(202) is provided. The method includes forming a pixel definition layer(20) on the base substrate(10), the pixel definition layer(20) being formed in the inter-subpixel region(202) and defining the subpixel region(201) of the organic light emitting diode display substrate; forming an insulating dielectric layer(50) on a side of the pixel definition layer(20) distal to the base substrate(10), the insulating dielectric layer(50) being formed to define a first aperture region(501) greater than the subpixel region(201); and, subsequent to forming the insulating dielectric layer(50), forming an organic light emitting layer(102) in each subpixel region(201) using a mask plate(30) placed on the insulating dielectric layer(50).
(FR) L'invention concerne un procédé de fabrication d'un substrat d'affichage à diodes électroluminescentes organiques comportant une région de sous-pixel (201) et une région entre sous-pixels (202). Le procédé consiste à former une couche de définition de pixels (20) sur le substrat de base (10), la couche de définition de pixels (20) étant formée dans la région entre sous-pixels (202) et délimitant la région de sous-pixel (201) du substrat d'affichage à diodes électroluminescentes organiques ; à former une couche diélectrique isolante (50) sur un côté de la couche de définition de pixels (20) distal par rapport au substrat de base (10), la couche diélectrique isolante (50) étant formée de façon à délimiter une première région d'ouverture (501) plus grande que la région de sous-pixel (201) ; et, après la formation de la couche diélectrique isolante (50), à former une couche électroluminescente organique (102) dans chaque région de sous-pixel (201) à l'aide d'une plaque de masque (30) placée sur la couche diélectrique isolante (50).
