“…On the other hand, although the angle-switchable display devices developed in recent years can switch between wide-viewing angles and narrow-viewing angles, − they typically need additional panels or backlight units, resulting in increased manufacturing cost, weight, and device thickness. At the same time, higher driving voltages increase power consumption, which limits their practical applications in real-life scenarios. − These observations indicate that considering economic costs and practicality, it is crucial to develop cost-effective antipeeping films that are thin and easy to manufacture and have high front transparency.…”

With the widespread use of electronic display devices such as smartphones and tablets, the demand for privacy protection has been steadily increasing. While the traditional shutter privacy films offer a decent antipeeping effect, they suffer from thickness, high costs, and poor frontfacing transparency, affecting the user experience. To solve this problem, and also based on the facts that the linearly polarized light (LPL) emitted by displays and the angular dependence of hybrid-aligned liquid crystal (LC) for LPL, for the first time, here we develop the optical composite films for display antipeeping application based on a polarization-dependent strategy. By combining a hybrid-aligned LC polymer (HLCP) film with a polarizing film (PF), the flexible composite film exhibits excellent narrow viewing angle capability while maintaining high front-facing transmittance, minimizing backlight loss. Furthermore, to achieve a polarizer-free system, we prepared the dichroic dye-doped HLCP film and transferred the consequent film onto optical clear adhesive (OCA). The experimental results confirm that this composite film also exhibits a narrow viewing angle property, which offers an approach for the study of display viewing angle control. These two polarized optical composite films based on HLCP have the potential for practical antipeeping applications in current mainstream display devices.

Graphene oxide (GO)-doped dimethyl sulfate (DMS)/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) superconductive alignment layer, aligning liquid crystals (LCs) with super switching and non-residual direct current (non-residual DC) performance, is presented in this manuscript. Doping of GO increased the pristine polar energy of a thin composite layer as well as the corresponding anchoring energy of the LCs sandwiched between these thin layers but only slightly affected the thin layers' morphology. When rubbed GO/DMS/PEDOT:PSS composite layers were used as alignment layers, a homogeneous alignment of nematic LCs was observed with competitive optoelectrical switching properties and non-residual DC performance because of the enhanced field effect and charge transport induced by the doped GO.
