OLED Display Panel and Method for Packaging the Same

摘要

A method for packaging an organic light-emitting diode (OLED) display panel includes: providing a package cover and an OLED substrate, and an OLED device arranged on OLED substrate; simultaneously printing a circle of a support and a hydrophobic barricade on an outer side of the package cover corresponding to the OLED device by means of screen printing, the support printed on an outer side of the hydrophobic barricade; and cementing the package cover and the OLED substrate. The hydrophobic barricade can effectively prevent external water vapor and oxygen from touching the OLED device. Therefore, the effect of package is enhanced, and the lifetime of the OLED device is prolonged. Further, the support and the hydrophobic barricade are formed at the same time through screen printing. Not only the method is simple but the efficiency is enhanced.

1. A method for packaging an organic light-emitting diode (OLED) display panel, comprising:
providing a package cover and an OLED substrate, and an OLED device arranged on OLED substrate; simultaneously printing a circle of a support and a hydrophobic barricade on an outer side of the package cover corresponding to the OLED device by means of screen printing, the support printed on an outer side of the hydrophobic barricade, and a width of the hydrophobic barricade being 100 um to 2000 um; cementing the package cover and the OLED substrate; a step of simultaneously printing a circle of the support and the hydrophobic barricade by means of screen printing comprising steps of: providing a template of screen printing comprising two patterned apertures, and shapes of the two patterned apertures matching shapes of the support and the hydrophobic barricade, respectively; arranging material for forming the support and material for forming the hydrophobic barricade on the template of screen printing; scratching the template of screen printing with a scraper, and blade-coating the materials forming the support and the hydrophobic barricade on the apertures corresponding to the template of screen printing.
