    摘要： An LED package and a lead frame include a reflector cup having a bottom surface with an LED asymmetrically positioned on the bottom surface and a wall surface inclined relative to the bottom surface and defining an opening at an upper end thereof. The bottom surface of the reflector cup has a first axial dimension along a first axis and a second axial dimension along a second axis, orthogonal to the first axis. A display having an asymmetrical FFP and asymmetrical screen curve includes an array of the LED modules including a plurality of LED packages. At least some of the LED packages include a dome-shaped lens asymmetrically positioned with respect to a geometric center of the bottom surface of the reflector cup.

    摘要： The present invention is directed to LED packages and LED displays utilizing LED packages where the peak emission of the LED displays can exhibit improved emission characteristics. In some embodiments the improved characteristics include a wider horizontal emission angle for the LED packages according to the present invention, which results in improved emission characteristics for the LED display such as a wider far field pattern. This provides improved picture intensity and quality when viewing the display at different horizontal viewing angles. Different embodiments also provide for improved emission characteristics for LED packages emitting different colors of light when viewing at different vertical angles. In one embodiment the red and green LED packages can have emission patterns that are substantially the same at different vertical viewing angles within a range. This helps the colors of the display appear consistent at those angles.

    摘要： LED packages and LED displays utilizing the LED packages are disclosed where the peak emission of the LED display can be tilted or shifted to customize its peak emission to the mounting height or location of the LED display. One embodiment of an LED display comprises a plurality of LED package where the peak emission from at least some of the LED packages is tilted off the package centerline. The LED packages are mounted within the display in such a way as to generate an image having a peak emission that is tilted off the perpendicular emission direction of the display.
