White oled display device and packaging method thereof

A white OLED (organic light-emitting diode) display device comprising:

• a glass cover plate;
• a color filter layer coated on the glass cover plate;
• a transparent protective layer covering the color filter layer;
• a hydrophobic layer self-assembled on the transparent protective layer;
• a desiccant layer disposed on the hydrophobic layer;
• and
• a TFT substrate formed with a white OLED layer;
• wherein the color filter layer, the transparent protective layer, the hydrophobic layer and the desiccant layer are sandwiched between the glass cover plate and the TFT substrate formed with the white OLED layer;
• wherein the white OLED display device further comprises a sealant, the sealant is coated at the periphery of the color filter layer, the transparent protective layer, the desiccant layer, the hydrophobic layer and the white OLED layer and sandwiched between the glass cover plate and the TFT substrate to thereby seal and protect internal coatings of the white OLED display device;
• the transparent protective layer is a Al2O3 layer, a WO3 layer, a ZnO layer or a ZnSe layer, which does not chemically react with the desiccant layer and is dense, and an area of the transparent protective layer is larger than or equal to an area of the color filter layer to thereby ensure the transparent protective layer completely covering the color filter layer;
• the glass cover plate, the color filter layer, the transparent protective layer, the desiccant layer and the hydrophobic layer are vacuum bonded with the TFT substrate formed with the white OLED layer;
• a filling method for the desiccant layer is screen printing, drop coating or dispensing.
