摘要： An integrated back light unit can include a light guide plate having a non-uniform distribution of extraction features. The non-uniform distribution of the extraction features can be provided by an extraction-feature-free region in proximity to a light emitting device, and/or by a variable density of the extraction features that changes with distance from the light emitting device. Additionally or alternatively, the light guide unit can include a heterogeneous reflectivity surface that has a different reflectivity at proximity to the light emitting device assembly than at a distal portion of the light guide unit. The different reflectivity may be provided by a specular reflective material, diffusive reflective material, or a light absorbing material. The non-uniform distribution of extraction features and/or the heterogeneous reflectivity surface can be employed to enhance brightness uniformity of the reflective light and/or to control the temperature distribution within the light guide unit.

摘要： Light guide design for an edge-type backlight unit in a display device. The upper surface of the guide (120) is divided by a step into two regions: Reg. I (130) and Reg. II (140); moreover, the guide exhibits a recess or indented channel at its edge opposite to the light sources (112). In each region the guide has a different thickness, with the upper surface in Reg. II being set back from Reg. I by the step. Optical sheets (160) are disposed on the guide surface in Reg. II abutting the step and may be held in place by tabs 142 on the guide surface. The recess at the edge of the guide in Reg. I may accommodate the light sources. The design saves space, reduces light leakage and enhances the reliability of light emission in the backlight. Optionally, reflective films may be arranged in the recess and/or on the lower surface of the guide in Reg. II. A light-scattering pattern may also be arranged on the upper surface in Reg. I. The lower surface of the guide may be inclined in Reg. II, so that the guide has a wedge shape. Indications for preferable sizes, size ratios and shapes (e.g. curvature) for both the recess and the step are given.

摘要： A directional backlight is disclosed. The directional backlight has a directional backplane that has a plurality of directional pixels to scatter a plurality of input planar lightbeams into a plurality of directional lightbeams. Each directional lightbeam has a direction and angular spread controlled by characteristics of a directional pixel in the plurality of directional pixels. A modulation layer having a plurality of modulators modulates the plurality of directional lightbeams. The directional backlight can be used to generate a 3D image with multiple views by specifying the characteristics of the directional pixels in the directional backplane.

摘要： An illumination device (200-c;200-d) includes a light source (210-c;210-d) configured to emit, during operation, light with a prevalent direction of propagation different from a direction of an optical axis (102-c) of the illumination device; and an optical coupler (220-c;220-d) including a transparent material, the optical coupler having an input aperture, an exit aperture (225-c,225-d) and a first side surface (224-c;224-d) and a second side surface (226-c;226-d) arranged between the input aperture and the exit aperture (225-c;225-d), the exit aperture being centered on the optical axis of the illumination device. The optical coupler (220-c;220-d) receives the emitted light through the input aperture from the light source. Further, the first side surface and the second side surface redirect the received light via total internal reflection (TIR) to the exit aperture. Additionally, the redirected light is issued through the exit aperture.
