  • Publication number: 20230393414
    Abstract: Provided is a medium-free projection system, comprising: a divergent beam emitted from a light source is collimated and homogenized by a light homogenizing rod and a first Fresnel lens and serves as incident light of a thin film crystal liquid crystal display screen, and a beam emitted from the thin film crystal liquid crystal display screen passes through a collimating optical element, and is converged by an imaging optical assembly into a target region to form an image, so that each point of the beam on an image plane fills an eye box. That is, the image suspended in air can be viewed by naked eyes in the range of the eye box, thereby realizing medium-free projection.

  • Publication number: 20230384585
    Abstract: An optical module and an optical system thereof for head-up display, and a vehicle, relating to the technical field of head-up display. The optical module includes an image generation element and a light blocking assembly which are provided in sequence; the image generation element is used for forming an image signal, the image signal being incident on a receiving end through the light blocking assembly; and the light blocking assembly is further used for transmitting part of light in external light according to a polarization direction and/or wavelength. The image signal is not affected by the light blocking assembly when passing through the light blocking assembly; the external light passes through the light blocking assembly and the image generation element in sequence, and does not generate an image after passing through the image generation element; light heat of the external light would be gathered on the image generation element.

  • Patent number: 10692419
    Abstract: Provided are a display panel, a display device and a display method of the display panel. The display panel includes a pixel array, where the pixel array includes a plurality of pixel groups and each of the plurality of pixels group includes first-type pixel units and second-type pixel units; and a drive circuit configured to provide a drive signal for the pixel array. A display mode of the display panel includes a high-definition display mode in which within one-frame time, the first-type pixel units and the second-type pixel units collectively display a same to-be-displayed picture; a stereoscopic display mode in which the first-type pixel units display a user's left-eye picture within first time and the second-type pixel units display a user's right-eye picture within second time; and a power saving display mode in which the first-type pixel units display a picture and the second-type pixel units do not perform displaying.
