    摘要: Disclosed are a display panel, a method for controlling a display panel, and a display device. The display panel includes a light-emitting substrate and an optical modulation structure which are laminated; and the optical modulation structure supports a first state and a second state which are switchable. In the first state of the optical modulation structure, a first light-emitting unit forms an image at a first position. In the second state of the optical modulation structure, the first light-emitting unit forms an image at a second position. According to the present disclosure, with the optical modulation structure, each light-emitting unit is enabled to form two images at different positions in different states. In this way, the state of the optical modulation structure can be continuously switched without increasing the number of light-emitting units, thereby improving a display effect of the display panel.

    摘要: 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.

    摘要: The present disclosure provides a display panel and a display device. The display panel includes a pixel unit including first and second sub-unit regions. Liquid crystal molecules in the liquid crystal layer corresponding to the first sub-unit region have a first initial alignment direction, and liquid crystal molecules in the liquid crystal layer corresponding to the second sub-unit region have a second initial alignment direction. The pixel unit further includes a third sub-unit region arranged between the first and second sub-unit regions. Liquid crystal molecules in the liquid crystal layer corresponding to the third sub-unit region have a third initial alignment direction, which is an alignment direction in a rotation from the first initial alignment direction towards the second initial alignment direction along a first rotation direction. An angle difference between the first and second initial alignment directions is greater than 0° and less than or equal to 90°.

    摘要: The embodiments of the present invention provide a liquid crystal display panel and a display device. The liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer. A first grating layer is arranged on a side of a first basal substrate departing from the second substrate, a scattering layer is arranged on a side of the first grating layer departing from the second substrate, the first grating layer includes a plurality of first light shielding walls and first transparent columns arranged alternately. The liquid crystal in the liquid crystal layer is doped with a polymerizable liquid crystal monomer with a predetermined volume ratio. Normal display of bright and dark states can be realized without a polarizer, and the transmittance is improved. The phase retardation can also be achieved without the cooperation of polarizer and liquid crystal, eliminating the issue of viewing angle.
