Abstract
The present disclosure provides a white-light block polymer, an ink composition, and a manufacturing method thereof. The white-light block polymer makes it only necessary to print one ink when using inkjet printing, thereby simplifying inkjet printing processing and meanwhile preventing a crosstalk problem of pixels having different colors of light. The present disclosure makes the ink composition suitable for inkjet printing by properly mixing the white-light block polymer, an organic solvent, a surface tension modifier, and a viscosity modifier in a suitable ratio.
