System for Collimating Backlight
First Claim
1. A collimating device for use in a system having a backlight, the collimating device comprising:
- an immersing layer;
a reflecting layer; and
an optical element layer formed from a plurality of three-dimensional, optical elements, each optical element having a light input end and a light output end, each optical element being tapered towards the backlight such that the light input end has a horizontal plan cross-sectional area that is less than that of the light output end, and wherein the reflecting layer has apertures therein which correspond to the position and shape of the light input ends of the optical elements.

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.

15. A transflector configured to reflect light arriving from a first direction and to transmit light arriving from a second direction opposite the first direction, the transflector comprising:
- at least one immersing layer, including a first immersing layer having a first and second side, wherein the first side faces a backlight that projects light in the first direction and the second side faces light arriving from the second direction;
at least one reflective layer, including a first reflective layer having a first and second side, wherein the first side faces the backlight and the second side faces light arriving from the second direction;
at least one optical element layer, including a first optical element layer having a first set of optical elements, wherein each of the first set of optical elements are tapered towards the light arriving from the second direction, such each optical element has a small area end and a large area end, wherein the large area end of each of the first set of optical elements contacts the large area end of another of the first set of optical elements, and wherein the first reflective layer has apertures therein which correspond to the positioning and shape of the small area ends of each of the first set of optical elements. - View Dependent Claims (16, 17, 18, 19, 20)
