  • Patent number: 8582041
    Abstract: Moirés due to interference between two liquid crystal display panels in a display device which achieves three-dimensional displaying by using two liquid crystal display panels is to be prevented. By disposing a lenticular lens array between an upper liquid crystal display panel and a lower liquid crystal display panel, moirés and image blurs are prevented. This configuration can prevent the luminance levels and contrast of images from dropping.

  • Patent number: 7679691
    Abstract: The present invention prevents a moiré generated by the interference of two liquid crystal display panels in a display device capable of performing a three-dimensional display using two liquid crystal display panels. By arranging an upper lens array and a lower lens array between an upper liquid crystal display panel and a lower liquid crystal display panel, a moiré and smearing of an image can be prevented. Due to such a constitution, lowering of brightness and contrast can be suppressed.

  • Patent number: 6776844
    Abstract: A production device to produce an organic EL display includes a solution in which a light emitting material is dissolved, and a flying electrode to receive solution from the container. A voltage is applied between the tip of the flying electrode and an electrically conductive material of an organic EL substrate to form an electrostatic field, and the tip of the flying electrode and the organic EL substrate are shifted relative to one another in at least one of a perpendicular direction and a horizontal direction. With this arrangement, the solution is formed into a stringy beam from the tip of the flying electrode to it fly onto the organic EL, substrate, thereby injecting the solution into a concavity formed and surrounded by banks on the organic EL substrate, and forming red, green and blue light emitting layers.
