Modifying The Appearance Of Television Pictures By Optical Filters Or Diffusing Screens (epo) Patents (Class 348/E5.136)
  • Patent number: 11372135
    Abstract: An angular selective film is configured to have a higher transmittance for radiation having an incidence angle in a specified range as compared to radiation having an incidence angle outside of the specified range, and includes a plurality of multilayer modules stacked substantially along a normal direction of the angular selective film. Each multilayer module includes at least first and second polymer layers, which have at least one of the following properties: (i) the first polymer layer is isotropic, the second polymer layer is anisotropic, the refractive indices of the first and second polymer layers are substantially the same in a first direction, and are different in a second direction, or (ii) both the first and second polymer layers are anisotropic, the refractive indices of the first and second layers are substantially the same in a first direction, and are different in the second direction.

  • Patent number: 11327358
    Abstract: A privacy display comprises a spatial light modulator and a passive retarder arranged between first and second polarisers arranged in series with the spatial light modulator. On-axis light from the spatial light modulator is directed without loss, and off-axis light has reduced luminance. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction over a wide polar field of view. Off-axis visibility of the display in an automotive vehicle can be reduced.

  • Patent number: 11150488
    Abstract: A display system may include a display screen configured to display an image, a backlight configured to provide collimated or substantially collimated light to the display screen, and a transparent contoured projection screen. The transparent contoured projection screen may include portions at different elevations to display different elements to a viewer in a three dimensional manner.

  • Patent number: 10185064
    Abstract: An electronic display comprises a display matrix, an image-correcting layer, and a luminance-correcting layer. The display matrix includes a flat face portion, a curved corner portion, a light-releasing surface, and a series of pixels extending across the flat face portion and around the curved corner portion. Coupled to the light-releasing surface of the display matrix, the image-correcting layer is configured to transmit light released from the flat face portion of the display matrix and to reorient light released from the curved corner portion of the display matrix such that the transmitted light and the reoriented light exit the image-correcting layer substantially in parallel, forming an apparent plane image of the series of pixels. Arranged between the light-releasing display surface and the image-correcting layer, the luminance-correcting layer is configured to deflect the light released from the curved corner portion into an acceptance profile of the image-correcting layer.

  • Patent number: 8054554
    Abstract: A display apparatus is provided. The display apparatus includes a front side that is exposed the outside. A refractor or set of refractors is positioned so as to minimize the appearance of a shield member to a viewer, thus causing a non-display region of the display apparatus to appear to be smaller than its actual size, thus increasing a size of an image display region of the display apparatus.
