Abstract
The present invention provides a white OLED display device and a packaging method thereof. The white OLED display device includes: 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 disposed with a white OLED layer. 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 disposed with the white OLED layer. The white OLED display device provided by the invention disposes the hydrophobic layer on the transparent protective layer, which can avoid the occurrence of mura caused by uneven distribution of desiccant.
