  • Patent number: 11016320
    Abstract: A display device with viewing angle switching, and its display method and fabrication method are provided. The display device includes a display module and a guest-host effect box. The guest-host effect box includes a first substrate, a second substrate, and a display dielectric layer. A first transparent electrode is disposed on a surface of the first substrate and a second transparent electrode is disposed on a surface of the second substrate. A first alignment film layer is disposed on a surface of the first transparent electrode, and a second alignment film layer is disposed on a surface of the second transparent electrode. When a bias voltage is not applied to the first and second transparent electrodes, a display mode is a narrow viewing angle mode; and when the bias voltage is applied to the first and second transparent electrodes, the display mode is a wide viewing angle mode.

  • Patent number: 10802359
    Abstract: The present disclosure provides a display panel, display device and display method. Under a wide viewing angle display mode, a first signal is applied to a first electrode and a second electrode, and a long axis of liquid crystal molecules and a long axis of dye molecules are perpendicular to a plane of a first substrate. A relatively large included angle is formed between a polarization direction of emergent light of a first display device and the long axis of the dye molecules. A second signal is applied to the first electrode and the second electrode under a narrow viewing angle display mode, and a long axis of liquid crystal molecules and a long axis of dye molecules form an included angle of 30 to 60 degrees together with the plane of the first substrate.
