AI Technical Summary
Existing quantum dot ink compositions are prone to nozzle clogging and reduced single-layer thickness during inkjet printing, making it difficult to maintain low viscosity and high gloss efficiency. Furthermore, the high degassing problem caused by traditional surface modification materials has not been effectively solved.
Quantum dots are modified using surface modifiers represented by chemical formulas 1 and 2, and polymerizable compounds and light diffusing agents are combined to form solvent-free or low-solvent curable compositions. The viscosity is reduced and degassing is minimized by adjusting the structure of the surface modifiers.
The low viscosity and low degassing characteristics of quantum dot inks were achieved, which improved inkjet processability and light efficiency, and ensured the uniformity and optical performance of the cured layer.
