Method for packaging the OLED display panel using screen printing
View Patent ↗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
cementing the package cover and the OLED substrate.
2. The method of claim 1 , wherein a step of simultaneously printing a circle of the support and the hydrophobic barricade by means of screen printing comprises 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.
3. The method of claim 2 , wherein the hydrophobic barricade is made from a solution, and after the package cover and the OLED substrate are cemented, steps further comprise:
shining and solidifying the material for forming the support with ultraviolet (UV) rays; and
drying the solidified support and the solidified solution.
4. The method of claim 3 , wherein the solution is a solution with organic silicon, and the solution with the organic silicon comprises a long chain silane coupling agent and vinyltriethoxysilane (VTES).
