AB  - Bistable hybrid-aligned nematic (HAN) liquid crystal devices (LCDs) with silica 
      nanoparticle-coated polyimide alignment films were investigated. It was observed 
      that the existence of the internal electric field produced from the 
      triboelectrically charged silica nanoparticles layer and impurity ions in the LC 
      reduced the total free energy of the HAN-LCD and stabilized the cell in the 
      homeotropic state. The stable homeotropic state can be switched back to the HAN 
      state by changing the ion distribution through a voltage pulse with proper 
      polarity. The capability of controlling bistability through modification of ion 
      density in the LC layer may have some applications, such as displaying a one-time 
      password requiring a specific stable time.
