Advanced Photolithography-Based Single-Layer RGB Cholesteric Liquid Crystal Display for Next-Generation Anticounterfeiting and Full-Color Reflective Display

To address technical bottlenecks associated with complex fabrication processes and extended manufacturing duration of conventional three-layer cholesteric liquid crystal (CLC) structures, photolithography and a chiral molecular precision diffusion strategy were integrated to prepare monolayer color-reflective photonic display panels. Moreover, by developing monolayer-encapsulated CLC photonic displays, we effectively tackled key technical problems encompassing fine microstructure design, isolated RGB pixel fabrication, and high-precision color tuning of CLC. It is notable that the electric-field-driven CLC switching process was realized through red, green, and blue pixel unit color superposition. The fabricated monolayer color display possesses electric-field-regulated pattern switching functionality. Furthermore, a multimode anticounterfeiting model was successfully constructed based on the Bragg selective reflection characteristics of CLC. Within the model, the original matrix pattern presents varied visual information with obvious differences in color and brightness under varying illumination. Combining specific light source illumination with the matrix encoding table facilitates efficient decoding of encrypted information, significantly boosting CLC anticounterfeiting performance.
