  • Patent number: 7920216
    Abstract: A stereo image display, switching between a first display direction and a second display direction, includes a polarized light module for providing a polarized light. A first light grating unit is implemented on the light path of the polarized light. When the first light grating unit is activated, the polarized light is modulated to output light in every two column; and when it is turned off, all the polarized light substantially passes. A second grating unit is implemented on the light path of the polarized light. When the second light grating unit is activated, the polarized light is modulated to output light in every two row; and when it is turned off, all the polarized light substantially passes. By the light passing the light grating units, an image displaying unit displays a first image at odd columns or rows and a second image at even columns or rows.

  • Patent number: 7841847
    Abstract: A system for manufacturing a micro-retarder and a method for manufacturing the same are provided. The system for manufacturing a micro-retarder includes a carrying device, a heating device and a movement control device. The carrying device is used for carrying a polymolecule film. The polymolecule film is selected from a polymolecule film having an arrangement direction. The heating device is used for providing a heating source. The energy formed in the central area of the heating source is smaller than that in the peripheral area of the heating source. The movement control device is used for controlling the heating source and the polymolecule film to relatively move along a first direction, so that the adjusted heating source heats at least one partial area of the polymolecule film along the first direction and resumes the partial area of the polymolecule film to be non-directional.

An image guiding unit has multiple micro-image output terminals, which are arranged according to an array sequence being set, so as to guide the output images from the micro-display devices. A stereo-image discrete screen is coupled with the image guiding unit, so that the image can transit the stereo-image discrete screen through multiple column transparent regions for producing multiple viewing-zone images of the image with respect to the different viewing zones. The image guiding unit can be, for example, an optical fiber array unit or an array-type light guiding unit.
