Abstract:
1. A developing apparatus for organic electroluminescent display panels, comprising: a developing unit having a developing tank for supplying a developing solution and at least a spraying device for dispensing said developing solution uniformly to the surface of organic electroluminescent display panels, wherein said spraying devices are nozzles arranged in a N*M array for spraying said developing solution on said organic electroluminescent display panels in a crossed manner, said nozzles sway back and forth as said developing solution is sprayed, and said N and said M are the quantity of said spraying devices and said nozzles, respectively, and said N and said M are integers greater than 0; a cleaning unit having a first washing-bath and a second washing-bath, wherein the cleaning liquid used for cleaning said organic electroluminescent display panels in said second washing-bath is collected or recycled for the pre-rinse in said first washing-bath, which locates and connects the end of said developing unit, and said organic electroluminescent display panels is pre-rinsed in said first washing-bath and then is washed in said second washing-bath; a drying unit having at least an airflow drier, which locates and connects one end of said cleaning unit in order to dry said organic electroluminescent display panels after cleaning; and a transporting unit for transporting said electroluminescent display panels to go through said developing unit, said cleaning unit and said drying unit in a continuous manner; wherein said organic electroluminescent display panels are transported at a constant speed by said transporting unit of said developing apparatus.
