Fig. 3. （a） Liquid crystal cell with no voltage applied to both ends. The blue rod shape represents E7 liquid crystal molecules， the white rod shape represents RM257， and the gray rod shape represents AgNWs. The liquid crystal molecules and AgNWs are arranged in the orientation direction； （b） Liquid crystal cell with applied voltage， which causes the liquid crystal particles and AgNWs to stand up with the direction of the electric field due to the pressurization effect. The red arrows indicate the orientation directions of light orientation and friction orientation.

Fig. 5. Schematic diagram of the testing experiment principle. A polarized blue light with a wavelength of 450 nm and an intensity of 30 mW/cm² is used as the erasing light source； Polarized green light with a wavelength of 532 nm and intensity of 1 mW/cm² is used as the test light source for the receiver to sense changes in light intensity.
