Abstract: A liquid crystal display is configured such that a composite layer thereof is transparent to incident light in one voltage condition (e.g., in the absence of an applied voltage) and scatters incident light out of the display in another voltage condition (e.g., when a voltage is applied). The liquid crystal display does not need polarizers or color filters.

Abstract: 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.

Abstract: 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.
