  • Patent number: 10504437
    Abstract: This disclosure relates to a display panel, a control method thereof, a display device and a display system comprising such a display panel. The display panel includes a plurality of pixel units. Each pixel unit has a plurality of subpixels Each subpixel has a display subpixel and an interference subpixel. Additionally, the interference subpixel and the display subpixel are different in at least one of color and gray scale. The display panel also includes a first control unit configured to control the display subpixel to be switched on during a first period of time in each display period, and to control the interference subpixel to be switched off during the first period of time in each display period and switched on during a second period of time in each display period.

  • Patent number: 10140915
    Abstract: The present disclosure provides a display device, a display system and a display method. The display device includes a driver circuit, a display panel, and an interference unit arranged at a display side of the display panel. The driver circuit is configured to drive the display panel to display an image, and a time period for each frame of the image includes a display period and an interference period. During the display period, the interference unit is in a transparent state so as to enable light beams from the display panel to pass through the interference unit, and during the interference period, the interference unit is in an interference state so as to interfere with the light beams from the display panel.

  • Patent number: 10134362
    Abstract: A display device, a driving method thereof, a manufacturing method thereof and an anti-peeping display system are provided. The display device includes an interference display module and a first display panel disposed in a light-emitting direction of the interference display module. The light emitted by the interference display module is polarized light. In the display device, the light of an interference image generated by the interference display module will be superimposed to light of a display image generated by the first display panel, so that users can only view an unordered image and cannot view a normal image when viewing the display device under glasses-free state. The light emitted by the interference display module is polarized light, so that the normal display image can be obtained by filtering the polarized light with polarization spectacles which can filter such polarized light.
