    Abstract: The present disclosure provides a display panel, including: a reflector; a phase retarder configured to change a polarization direction of a light beam passing through the phase retarder; a light-absorbing black matrix configured to absorb the light beam; and a polarization scattering film. After passing through the polarization scattering film, a polarized light beam from a projector is transmitted along an original light path, then the polarized light beam is transmitted through the phase retarder, reflected by the reflector and directed again to the polarization scattering film so as to be scattered. After passing through the polarization scattering film, a light beam with a polarization direction different from the polarized light beam from the projector is scattered by the polarization scattering film and then absorbed by the light-absorbing black matrix.

    Abstract: Disclosed is a display device, which includes: a display panel, and a frontlight source arranged on at least one side of the display panel, where light emitted from the frontlight source is collimated light in the direction perpendicular to a light incidence face of the display panel. The light emitted from the frontlight source can only be incident onto the display panel in the direction perpendicular to the light incidence face of the display panel, and the light emitted from the frontlight source is collimated light with a uniformly distributed intensity in the direction perpendicular to the light incidence face of the display panel, so there is a uniform intensity distribution of light beams incident onto the display panel, thus resulting in high uniformity of brightness, and high contrast in the display device.

    Abstract: A stereoscopic display device and a stereoscopic display method are provided. The stereoscopic display device comprises: a display unit configured for displaying an image and emitting emergent light; and at least two active scattering panels arranged at a light-emitting side of the display unit and in different planes. The active scattering panels are configured for performing a scattering process to the emergent light, so that the emergent light, after being scattered by the different active scattering panels, forms a stereoscopic picture. By providing a plurality of active scattering panels to achieve stereoscopic display without the provision of a plurality of display panels, it is possible to avoid the problem that backlight emitted by a backlight source is subjected to a serious reduction in transmittance after passing through a plurality of layers of display panels, thereby improving display brightness of a stereoscopic display device.

    Abstract: The present invention relates to liquid display technology, and provides a liquid crystal display screen and a display device. A first and a second optical compensation film are disposed on each side of the liquid crystal layer respectively. By the first optical compensation film, a polarized light obtained from light non-normally incident into a first polarizing layer is compensated so that the polarized light becomes a first elliptically polarized light. By means of the phase retardation function of the liquid crystal layer, the first elliptically polarized light is converted into a second elliptically polarized light with its polarization direction consistent with that of the first elliptically polarized light and its rotation direction opposite to that of the first elliptically polarized light. By the second optical compensation film, the second elliptically polarized light is compensated into a polarized light capable of being absorbed completely by a second polarizing layer.
