Optical lens, optical package having the same, backlight assembly having the same, display device having the same, and method thereof
摘要：
An optical lens includes a recessed part and a refracting part. The recessed part has a substantially circular plan view and a substantially V shaped cross-section. The recessed part forms an angle of no more than an angle of about 20° with respect to a vertical line. The recessed part has a plurality of curved surfaces including different radii so that a light incident into the recessed part is totally reflected from the curved surfaces. The refracting part has a substantially circular plan view extended from the recessed part. A light incident into the refracting part and the reflected light from the recessed part are refracted from the refracting part. Therefore, a luminance uniformity and a color uniformity are improved.
摘要（中）：

光学透镜包括凹部和折射部。 该凹部具有大致圆形的平面图和大致V形的横截面。 凹部相对于垂直线形成不大于约20°的角度的角度。 凹部具有包括不同半径的多个弯曲面，使得入射到凹部的光从曲面全反射。 折射部具有从凹部延伸的大致圆形的平面图。 入射到折射部分的光和来自凹陷部分的反射光从折射部折射。 因此，提高亮度均匀性和颜色均匀性。
