Figure 1.

(a) Schematic of inkjet printing technology to achieve patterning of liquid crystal ink with different components. The pattern showing two kinds of distinct information demonstrates the structural color of “USTB” under natural light and the fluorescent color of “2022” under UV irradiation. (b) Schematic to show FCLC microdroplets with both structure color under natural light and fluorescent color under UV irradiation. (c) Summarized the optical properties of 4 different LC microdroplets. Red solid circle means only structural color of CLC but not fluorescent color; Green solid circle means only fluorescent color but not structural color; Solid green circles with red borders represent both structural color and fluorescent; Yellow solid circles represent neither structural color nor fluorescent.
