Ink composition for inkjet printing organic light-emitting diodes and method of manufacturing the same

An ink composition for inkjet printing organic light-emitting diodes, comprising:

• 0.01-40% of bipolar light emission component, 10-99.9% of solvent, 0.01-5% of surface tension modifier, and 0.01-5% of viscosity modifier by weight,
• wherein the bipolar light emission component is single-component light emission material selected from a group consisting of fluorescence material, phosphorescence material, thermally activated delayed fluorescence material, room temperature phosphorescence material, aggregation-induced delayed fluorescence material, free radical material, quantum dot material, excimer material, and exciplex material;
• or
• the bipolar light emission component is multi-component light emission material and comprises light emission material and host material, wherein the light emission material is selected from a group consisting of fluorescent material, phosphorescence material, thermally activated delayed fluorescence material, room temperature phosphorescence material, aggregation-induced delayed fluorescence material, free radical material, quantum dot material, excimer material, and exciplex material, and the host material is selected from single-component bipolar host material or multi-component bipolar host material.
