Abstract: A collimating device and a transflector for use in a system having a backlight is disclosed herein. In one embodiment of the application, the collimating device and the transflector each include an immersing layer, a reflecting layer, and an optical element layer formed from a plurality of three-dimensional, optical elements. Each optical element is tapered such that a small area end has a horizontal plane cross-sectional area that is less than that of a wide area end. The optical elements of the collimating device are tapered towards the backlight and the optical elements of the transflector are tapered away from the backlight. The reflecting layer has apertures which correspond to the position and shape of the light input ends of the optical elements.

Abstract: Integrated sub-assemblies for light management are disclosed herein. The integrated sub-assemblies include a plurality of films and/or elements, including a light collimating device and/or a transflecting device. At least two of the elements are coupled such that there is no air layer between the coupled elements.

Abstract: A method for manufacturing a collimating device is disclosed herein. In one embodiment the method includes a step of constructing a reflective layer. After the reflective layer is constructed, a step of constructing an optical element layer follows, including a step of forming an array of microstructures in the optical element layer. Next, the array of microstructures is abutted against the reflective layer. Heat and pressure are then applied to the optical element layer to puncture the reflective layer and penetrate a predetermined distance through the reflective layer. Sub-assemblies are also defined, wherein optical elements are coupled to prevent light loss.
