Fig. 6. The preparation of multiple channel dynamic addressing 3D holographic display.

a Schematic cartoon illustrating the four-pixel channels (each pixel channel with the size of 500 μm) of PDLC device and operation of each pixel is controlled by microcircuits (blue). b The operation of the four channels dynamic addressing 3D holography display with four flying airplane meaning four pixel channels were switch on state (the scale bar represents 0.5 cm). c–f 3D holographic image sequential switchover exhibition (from pixel 1 to pixel 4) of the four-channel 3D hologaphic display proving its dynamic addressing performance (the scale bar represents 0.5 cm). g When Pixel 1 was activated, the transmittance of each pixel was compared under the wavelength of 635 nm, which is indicating that the crosstalk between 1 and other 2, 3, 4 channel was near in zero. h The transmittance response through the four-pixel channels were cyclically modulated, resulting in periodic switch on and off states
