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： 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.
