  • Method and apparatus for printing on a photosensitive material using a liquid crystal display
    Patent number: 6437849
    Abstract: A method and apparatus for printing an image onto a photosensitive media. The apparatus comprises a light source for producing an exposure light and an imaging active matrix liquid crystal display for providing images. The exposure light passing through the liquid crystal display for printing the images on the liquid crystal display onto the media. The liquid display is moved between a first position and a second position. A zoom lens is provided for adjusting the size of the image area on the photosensitive material so that substantially the entire width of the photosensitive material is filled.
    Type: Grant

  • Method and apparatus for correcting light non-uniformity in an LCD photographic printer
    Patent number: 5870205
    Abstract: A method and apparatus for printing an image onto a photosensitive media. The apparatus includes an optical system having a light source for producing an exposure light; an imaging active matrix liquid crystal display through which the exposure light passes; a lens for focusing the exposure light passing through the active matrix liquid crystal display onto a photosensitive media; and a correction active matrix LCD is position between the imaging active matrix LCD and the light source for correcting non-uniformity in the optical exposure system.
