A brightness enhancement article for improving luminance from a light source includes a light-collecting prism surface forms a series of longitudinal trapezoidal prism elements in which each has a face plane disposed toward the light source and first and second legs extending back from the face plane, forming first and second base angles&#x3b2; with the face plane wherein both first and second base angles&#x3b2; satisfy: 90 degrees&#x3c;base angle &#x3b2;&#x3c;120 degrees.

Brightness enhancement article having trapezoidal prism surface

A system for processing a multilayer liquid crystal film display material, with multiple irradiation apparatus () for applying a zone of polarized UV irradiation onto a substrate fed from a web () with incident light at a desired angle. Each irradiation apparatus () includes a UV light source (), and one or more optional filters (). A polarizer () is provided, sized and arranged to polarize light over the web () as it moves. The irradiation apparatus () employs an array of louvers () and/or a prism array (). One irradiation apparatus () irradiates a first LPPlayer () at a 0-degree alignment, in the web movement direction, the other irradiation apparatus () irradiates an LPPlayer () with an orthogonal 90-degree alignment.

Apparatus and method for irradiating a substrate

An apparatus for printing images including an illumination optics ( ) that provides uniform area light is disclosed. A prism ( ) is located at a first position and receives the uniform area light and refracts the light. A first reflective LCD modulator ( ) modulates the refracted light on a site by site basis and reflects the first modulated light to a second position on a media plane. A motor ( ) rotates the prism ( ) around an axis parallel to the illumination optics to a third position. A second reflective LCD modulator ( ) modulates the refracted light on a site by site basis and reflects the second modulated light to a fourth position on the media plane.

Apparatus for printing high resolution images using reflective LCD modulators

An apparatus for printing images including illumination optics ( ) that provides uniform area light is disclosed. A mirror ( ) receives the uniform area light and redirects the light. A first reflective LCD modulator ( ) modulates the redirected light on a site by site basis and reflects the first modulated light to a media plane. A motor ( ) moves the mirror on a line parallel to the illumination optics. The mirror redirects the light to a second reflective LCD modulator ( ). The second reflective LCD modulator modulates the redirected light on a site by site basis and reflects the second modulated light to the media plane.

An apparatus for printing images including an illumination optics ( ) that provides uniform area light is disclosed. A polarizing beamsplitter ( ) receives the uniform area light and redirects a first polarization state of the light to a first reflective LCD modulator ( ) which modulates the first polarized light on a site by site basis and reflects the first modulator light through the polarizing beamsplitter ( ). A parallel plate tilted at a first angle spatially displaces the first modulated light along a first line normal to the polarizing beamsplitter ( ). A print lens assembly ( ) images the first modulated light to a first position on a media plane to print a first image. The parallel plate is moved to a second position ( ) and a new image is printed.

Method and apparatus for printing high resolution images using reflective LCD modulators

An apparatus for printing high resolution images on a photosensitive media (,) includes an array of LEDs (,) for forming a light beam uniformizing optics (,) and a condensor lens (,) which transforms the light beam to a telecentric beam. A polarizing beamsplitter (,) splits said telecentric beam into a first polarized beam and a second polarized beam and directs the first polarized beam to a first reflective LCD modulator (,) and directs the second polarized beam to a second reflective LCD modulator (,). The first reflective LCD modulator (,) rotates a first polarization state of the first polarized beam on a site by site basis to produce a first modulated polarized beam and reflects the first modulated polarized beam, in response to a first image data signal, through the polarizing beamsplitter (,). The second reflective LCD modulator (,) rotates the a second polarization state of the second polarized beam to produce a second modulated polarized beam and reflects the second modulated polarized beam, in response to a second image data signal, through the polarizing beamsplitter (,). A print lens(,) focuses the first and said second modulated polarized beams on the print media (,). In the preferred embodiment, the media is exposed in a color sequential manner with a two-dimensional color image. The media or the assembly may then be moved to a second position and a new image is printed.
