Abstract:
A method of fabricating a light emitting display panel. The method includes providing a substrate having a display area and a peripheral area, the substrate including a pixel definition layer for defining a plurality of subpixel apertures for a light emitting layer in the display area; attaching a solvent vapor compensation reservoir to the peripheral area of the substrate, the solvent vapor compensation reservoir having one or more ink droplet receiving grooves configured to receive an ink droplet and a connection layer, the solvent vapor compensation reservoir removably attached to the peripheral area of the substrate through the connection layer; dispensing ink droplets into the plurality of subpixel apertures and the one or more ink droplet receiving grooves; drying the ink droplets dispensed into the plurality of subpixel apertures and the one or more ink droplet receiving grooves; and removing the solvent vapor compensation reservoir from the substrate.
