Abstract
The present disclosure relates to an inkjet printing ink and application thereof. In one aspect, the inkjet printing ink includes a crosslinking type organic host material, an organic doped luminescent material, a surface tension modifier, a viscosity modifier, and a solvent. On the other aspect, the present disclosure provides printing the inkjet printing ink on a substrate of a display panel to be prepared, performing drying process, and performing baking process at 120° C. to form an organic light emitting layer. Therefore, avoiding the problem of mutual dissolution of the organic light emitting layer and the electron transport layer when the electron transport layer is printed on the organic light emitting layer, avoiding damage to the organic light emitting layer, realize an inkjet printing process of the organic electron transport layer, thereby reducing the cost of manufacturing.
