“…This method has the advantages of simple operation and cost saving, but the transmittance rate is damaged to a certain extent, and its improvement of off-axis viewing angle brightness is limited; On the basis of the original display and then add a layer of control of the viewing angle of the liquid crystal box can also be achieved on the viewing angle of the switch [4][5], but it increases the thickness of the display. In addition, some scholars have developed an optical micro-nano film to achieve a wide viewing angle of directional adjustment, but does not have the function of wide and narrow switching [6][7][8].…”

The market has seen an emergence of special viewing angle needs with the development of display devices. For instance, some consumers require displays with adjustable viewing angles to accommodate different scenarios. This paper proposes an optical micro‐nano film with an adjustable viewing angle effect. The rotation angle of liquid crystal molecules is controlled through the reasonable design of the liquid crystal layer's thickness and the voltage magnitude to achieve the control of the viewing angle. The display is best viewed at the center of the display when no voltage is applied. However, the quality of the wide viewing angle display is significantly better after voltage is applied. The simulation results indicate that the brightness in the viewing angle range of ‐27°to ‐23°and 37°to 41°is significantly improved after applying a voltage of 15V, suggesting a broad application prospect for this technology. In addition, the use of this technology reduces the difficulty of process preparation and makes it more universally applicable.
