Description

technical field

[0001] The present invention relates to a device for cleaning an ink-jet head, especially a device suitable for removing residues in the ink-jet head. Background technique

[0002] One of the mainstream technologies for manufacturing organic electroluminescent devices is to use inkjet printing to form organic electroluminescent layers (including small molecule organic electroluminescent layers and polymer organic electroluminescent layers). Inkjet printing is a printing method that uses pressure to eject ink from ink nozzles onto the surface of a substrate (such as an organic electroluminescence panel). There are many advantages of manufacturing organic electroluminescent elements by inkjet method. For example, there is no need to use a photomask or a screen, and only a single step is required to print the organic electroluminescent layer into any desired pattern, such as letters, numbers, rules, etc. Or irregular graphics, so its manufacturing process is si...
