An organic light emitting device and a method of manufacturing the same are provided. The organic light emitting device, from bottom to top, includes a substrate, an indium tin oxide layer, a semiconductor layer, and a pixel defining layer. The semiconductor layer covers foreign particles on the indium tin oxide layer to make the indium tin oxide layer have an even thickness. The method of manufacturing the organic light emitting device including steps of providing an indium tin oxide layer, providing a semiconductor layer, patterning, and providing a pixel defining layer. The disclosure prevents from uneven brightness (mura) causing from a bright spot or a dark spot appearing at the foreign particles and ensures an overall even brightness of the organic light emitting device by providing the semiconductor layer disposed on the indium tin oxide layer to cover foreign particles on the indium tin oxide layer.

The invention provides a recess structure for print deposition process and manufacturing method thereof. By disposing the dam () enclosing the recess () as comprising at least two stacked branch dam layers, and increasing the contact angle between the inclined inner circumferential surface of recess () enclosed by the branch dam layers and ink in a layer-by-layer manner, to limit height the ink able to climb on the inclined inner circumferential surface of the recess (), the invention can improve the thickness uniformity of the organic functional layers printed in the recess and the photoelectric properties of organic functional layers. The recess () fabricated by the manufacturing method can limit height the ink able to climb on inclined inner circumferential surface of the recess () to improve the thickness uniformity of the organic functional layers printed in the recess and the photoelectric properties of organic functional layers.

The present invention provides an OLED material vacuum thermal evaporating mask plate, comprising a mask frame (), a quickset () fixed on the mask frame () and a mask () fixed on the quickset (); the mask frame () comprises four edges, and the four edges surround to form an opening corresponding to the mask (); each edge of the mask frame () comprises a groove () dented at the upper surface; the quickset () is fixed in the groove (); the mask () is fixed on the quickset () by point weld, and welding points () are on the quickset (). When the mask deforms and the replacement is necessary, only the quickset is extracted for polishing or is replaced. The mask frame can be repeatedly used to diminish the waste amount and to raise the availability of the mask frame. Meanwhile, the spare amount of the mask frame can be reduced to save material and production cost.

Provided are a device and a method for preprocessing metallic magnesium. The device includes a chamber, a heating device mounted in the chamber, a gas inlet port mounted on the chamber, and a gas evacuation port mounted on the chamber. The gas inlet port is connected to external inert gas supply equipment for supplying an inert gas into the chamber. The gas evacuation port is connected to an external vacuum evacuation device to evacuate the chamber to vacuum. The heating device functions to heat metallic magnesium having an oxidized surface so as to sublimate a layer of magnesium oxide formed on the surface of the metallic magnesium in a vacuum environment to thereby obtain pure metallic magnesium.
