Abstract
A back light unit includes an array of LEDs positioned in rows and columns that emit light from a top surface. A light splitting optical film includes a plurality of inverted pyramids positioned on a first side facing the top surface of the array where each of the plurality of inverted pyramids forms an apex oriented in a direction away from the top surface of the array. A plurality of linear prisms is positioned in a parallel configuration on a second side facing away from the top surface of the array where at least some of the linear prisms form an apex being oriented such that a direction of the apex forms a desired angle with respect to a direction of a row of the array of light emitting diodes.
