Abstract
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.
