Filed:

Dec 7, 2001

Appl. No.:

10/014029

Inventors:

Thomas J. Haven - Portland OR
Kurt R. Munson - Tigard OR

Assignee:

Delta Electronics, Inc. - Taipei

International Classification:

G03B 2100

US Classification:

353 20, 353 31, 353 33, 353 84, 353102, 349 9, 348790

Abstract:

A projection display system includes a light source emitting a randomly polarized light and a polarization recapture system including a tunnel integrator and a transmitting/reflecting polarizer coupled to the output end of the tunnel integrator. The input end of the tunnel integrator includes an input aperture and a reflective inside surface coated with a quarter wave retarder. In operation, the randomly polarized light enters the tunnel integrator through the input aperture. The polarization recapture system transmits light having a first polarization as polarized light output and recycles light having a second polarization orthogonal to the first polarization. The light having the second polarization is reflected by the transmitting/reflecting polarizer back into the tunnel integrator. The polarization recapture system recycles the light having the second polarization by reflecting and reorienting the light having the second polarization to light of the first polarization.

International Classification:

H04N 5/64

US Classification:

348836

Abstract:

In one embodiment, an electronic display apparatus for installation on a display case merchandiser having a door with a transparent front panel is disclosed. The apparatus comprises a bezel, a transparent electronic image display panel, and a light source. The bezel is configured to attach to the door of the merchandiser so a portion of the transparent front panel of the door is viewable through an opening of the bezel. The display overlays at least a portion of the bezel opening and a portion of the transparent front panel of the door when the apparatus is installed. The light source fits in a gap formed between the bezel and the door when the apparatus is installed.

US Classification:

359 54

Abstract:

A non-emissive flat panel display, such as an LCD having a plurality of pixels defined by the overlapping areas of row and column electrodes, is provided with a novel mask arrangement to block light from leaking through the interpixel spaces or gaps without electrically shorting the electrodes. The light-blocking mask is split into two parts, with one part deposited on each substrate to block the light from being transmitted through the inter-electrode gaps on the opposite substrate to improve the contrast ratio of the display.
