Some implementations described herein involve defining a viewing angle range, also referred to herein as a viewing cone. The viewing cone may be produced by an array of optical fibers on a display. The optical fiber array may include tapered optical fibers that are capable of increasing the amount of light transmitted through the optical fiber array. The optical fiber array may be a graded index optical fiber array, wherein the refractive index of the optical fiber cores varies along the axis of the optical fibers.
