  • Patent number: 7841733
    Abstract: A display device such as a light box comprises: a housing; a light source accommodated in this housing; and at least one diffusely translucent display face illuminated by the light from this light source. Orienting means are added to the light source so as to obtain a directional characteristic of the light emitted by the light source such that the light source directly illuminates at least one wall almost exclusively. This at least one wall is diffusely reflective such that a part of the light incident thereon is reflected to the display face. This has an almost constant luminance as a result.

  • Patent number: 7800708
    Abstract: A backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide formed from a plurality of segments. Each segment has a first side and a second side opposite the first side, and a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. The plurality of segments are arranged substantially in parallel with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display. A light source is disposed along only one of the first side or second side of each segment for transmitting light into the light guide from either the first side or second side. Each segment light source is selectively turned on and off in a particular pattern.

  • Patent number: 7780304
    Abstract: A vehicle instrument cluster lens assembly for achieving a desired smoked lens effect in a vehicle instrument panel includes a first layer having an associated polarizing orientation for transforming incident light into polarized light having a first orientation that corresponds to the polarizing orientation. A second layer receives the polarized light and shifts the first orientation of the polarized light to a second orientation that is different than the first orientation. A surface receives the polarized light from the second layer and at least partially reflects the polarized light in a direction toward the second layer. The second layer shifts the second orientation of the polarized light to a third orientation that is different from the polarizing orientation of the first layer to prevent the polarized light from being transmitted to a vehicle occupant.

    Abstract: A method for selecting paints is disclosed. This method includes the steps of selecting true paint colors, displaying device-dependent colors corresponding to the true paint colors in a simulated full size room and interacting with the buyers to change the displayed colors and select the desired colors. The method also includes the step of dispensing paints corresponding to the selected colors. The displayed colors are generated by multiple color and/or white LEDs to provide a wider gamut of displayable colors and more color saturation and chromatic. A full-size apparatus for displaying paint colors using device-dependent colors is also disclosed.

  • Patent number: RE42975
    Abstract: The present invention features a system for uniformly distributing luminance and a high degree of collimation from a back light module for flat-panel, liquid crystal displays (LCDs) simultaneously. A constant and uniform luminance output of the back light module in two directions is obtained through appropriate selection of lamps, geometry and optical components. An appropriate balance of lamps, lamp spacing, diffusers and light collimating optics are chosen to produce a high brightness back light module with very high intensity output over two very large surfaces. Variations in intensity over the illuminated area are minimized using light recycling in conjunction with the reflective diffusers and collimating optics. Precision collimators eliminate light beyond a defined angle, as required in tiled or monolithic flat-panel LCDs with predetermined display specifications.
