Abstract
The present disclosure provides an organic light emitting diode display package structure and a method of manufacturing the same. The organic light emitting diode display package structure is provided with a gate insulating layer, a first barrier layer, a first organic buffer layer, a first hydrophobic layer, a second organic buffer layer, and a second barrier layer which are disposed sequentially. A double layer of the organic buffer layer has a thickness capable of wrapping the foreign matters in the area to lower the possibility that the water and oxygen pass through this area and enter OLED device to enhance the protection ability of the TFE on the OLED device.
Claims8
An organic light emitting diode (OLED) display package structure, comprising:
- a gate insulating layer having thereon a pixel definition layer and a blocking wall, wherein a working area is disposed between a boundary of an effective display area of the pixel definition layer and the blocking wall;
- a first barrier layer covering on the pixel definition layer and the blocking wall;
- a first organic buffer layer disposed on the first barrier layer over the pixel definition layer;
- a first hydrophobic layer disposed on the first organic buffer layer over the working area, wherein the first hydrophobic layer is provided with nano microstructures on a surface for limiting a boundary of the first organic buffer layer;
- a second organic buffer layer disposed on the first hydrophobic layer;
- a second barrier layer covering on the second organic buffer layer;
- a second hydrophobic layer disposed on the second organic buffer layer, wherein a surface of the second hydrophobic layer is provided with nano microstructures for limiting a boundary of the second organic buffer layer;
- and
- a third organic buffer layer disposed between the second hydrophobic layer and the second barrier layer.
