Abstract: A display panel and a display device are disclosed. The display panel includes a display liquid crystal cell, a first polarizer, a switchable liquid crystal cell, and a second polarizer. A first substrate and a second substrate of the switchable liquid crystal cell are formed of transparent flexible substrates which are substituted for glass substrates, and a first phase compensation film group including at least a first C-type compensation film group is provided, which is used to compensate the phase difference caused by the phase retardation when the polarized light passes through the transparent flexible substrates, thereby reducing the thickness and weight of the display panel.

Abstract: A display panel and a display device are provided. The display panel includes a panel main body. A first dimming element is disposed on a side of the panel main body. The first dimming element has a first alignment direction. A second dimming element is disposed on a side of the panel main body away from the first dimming element or between the first dimming element and the panel body. The second dimming element has a second alignment direction. The first alignment direction is perpendicular to the second alignment direction. The applicability of the display panel is improved, and it has an anti-peeping effect.

Abstract: A display device and a dimming device are provided. A dimming layer is located between a first polarizer and a second polarizer whose transmission axes are parallel to each other. When the display device is in a first display mode, long axes of the liquid crystal molecules distributed in the first polymer network are arranged along the second direction, and long axis of the liquid crystal molecules distributed in the second polymer network are arranged along the third direction. The third direction and the second direction respectively point to opposite sides of a normal line of the first polarizer.

Abstract: The present application discloses a display module and a display device. The display module includes a light grating assembly. The light grating assembly includes alternately arranged first regions and second regions, and liquid crystal molecules and dye molecules distributed in the first regions and the second regions. Arrangement of the liquid crystal molecules and the dye molecules are controlled to make the first regions light-transmissive and the second regions light-transmissive under a first mode and not light-transmissive under a second mode to form alternately light and dark stripes under the second mode.
