  • Patent number: 12292652
    Abstract: Some implementations pertain to a transflective display device comprising a display surface, an optical path, and/or other components. The optical path may spatially modulate light emitted from a primary light source and direct it to the display surface, generating a display of visual information. The optical path may include a reflective spatial light modulator and a set of Light Emitting Diodes. The modulator may receive light from the primary light source and selectively reflect it toward the display surface. The Light Emitting Diodes may emit light directed to the backside of the modulator, including white light and light of a first color. Some implementations may include drivers to control the intensity of the light emitted by the Light Emitting Diodes, dictating the tone of the light transmitted through the modulator. This configuration may facilitate the creation of a uniform, high-quality display.

  • Patent number: 12289435
    Abstract: A display device includes: a display panel with pixels; a light source with light emission points; an acquirer configured to acquire viewpoint information; and a controller configured to control image display based on the viewpoint information on positions of viewpoints and an arrangement direction of the viewpoints. The controller is configured to drive some or all of pixels positioned on straight lines each connecting a corresponding one of the light emission points to a corresponding one of the viewpoints based on a relative rotation angle between the display panel and the arrangement direction and a relative positional relation between the viewpoints and the light emission points. The light emission points are individually switchable between a turned-on state and a turned-off state. A pitch of the light emission points is smaller than a pitch of light emission points controlled to be turned on when outputting an individual image to each viewpoint.
