Abstract： The conventional paterning of PSCLC films relies on prefabricated photomasks or complex micro/ nano fabrication processes，which are costly and limited flexibility，thus restricting their applications in personalized optical devices.In this work，a drop-on-demand inkjet printing technique is employed to achieve rapid and eficient paterning，enabling programmable and highly designable liquid crystal patterns.A birefringent film is introduced to enhance optical modulation eficiency and realize gradient color variations.Experimentally，the reflection peaks of red，green，and blue PSCLC materials are centered at 680nm ， 550nm ，and 490nm ，respectively，and all enter a scattering state under applied DC voltages，demonstrating excellent electro-optical responsiveness.By optimizing the viscosity of the liquid crystal solution and the driving waveform，uniform PSCLC pixel arays with a minimum pixel size of 60 （20号 μm are successfully fabricated，verifying the feasibility of the inkjet printing process.This low-cost and scalable patterning method significantly improves the precision of PSCLC patterning.It also expands their potential applications in flexible displays，smart photonic devices，and tunable optical elements.
